 webmagic
 ---------
-####*一个网络爬虫工具包*
+[![Build Status](https://travis-ci.org/code4craft/webmagic.png?branch=master)](https://travis-ci.org/code4craft/webmagic)
 
-webmagic的发起源于工作中的需要，其定位是帮助开发者更便捷的开发一个垂直的网络爬虫。webmagic可以便捷的使用xpath和正则表达式进行链接和内容的提取，对于有Java和xpath或者正则基础的开发者，只需编写少量代码即可完成一个定制爬虫。
+>webmagic是一个开源的Java垂直爬虫框架，目标是简化爬虫的开发流程，让开发者专注于逻辑功能的开发。webmagic的核心非常简单，但是覆盖爬虫的整个流程，也是很好的学习爬虫开发的材料。作者曾经在前公司进行过一年的垂直爬虫的开发，webmagic就是为了解决爬虫开发的一些重复劳动而产生的框架。
 
-###哲学###
+>web爬虫是一种技术，webmagic致力于将这种技术的实现成本降低，但是出于对资源提供者的尊重，webmagic不会做反封锁的事情，包括：验证码破解、代理切换、自动登录、抓取静态资源等。
 
-* Write Less, Do more.
+webmagic的主要特色：
 
-	webmagic是一个开发者的工具包，它的目标是让开发者可以通过更少的代码，实现一个高质量的爬虫。webmagic内部还集成了一些常见的垂直性爬虫的功能，例如针对页面正文的Readability技术，可以直接对页面的正文进行智能提取。
-	
-	以下是爬取oschina博客的一段代码：
-	
-		Spider.me().processor(new SimplePageProcessor("http://my.oschina.net/", "http://my.oschina.net/*/blog/*")).run();
+* 核心简单但是涵盖爬虫的全部流程，灵活而强大，也是学习爬虫入门的好材料。
+* 提供丰富的抽取页面API。
+* 无配置，但是可通过POJO+注解形式实现一个爬虫。
+* 支持多线程。
+* 支持分布式。
+* 支持爬取js动态渲染的页面。
+* 无框架依赖，可以灵活的嵌入到项目中去。
+
+webmagic的架构和设计参考了以下两个项目，感谢以下两个项目的作者：
+
+python爬虫 **scrapy** [https://github.com/scrapy/scrapy](https://github.com/scrapy/scrapy)
+
+Java爬虫 **Spiderman** [https://gitcafe.com/laiweiwei/Spiderman](https://gitcafe.com/laiweiwei/Spiderman)
 
-* 简单可用
+## 快速开始
 
-	webmagic的功能覆盖整个爬虫的生命周期(链接提取、页面下载、内容抽取、持久化)，是一个完整的爬虫框架。但是与其他Full-Stack的框架不同，webmagic只引入少量约定，大部分功能都通过简单的API调用完成，目的是尽量降低开发者的学习成本。webmagic以jar包的形式存在，并且不依赖任何框架，在程序可以随处进行调用。
+### 使用maven
 
-* 灵活性
+webmagic使用maven管理依赖，你可以直接下载webmagic源码进行编译：
 
-	参考scrapy的设计，webmagic将爬虫的扩展点分为processor、schedular、downloader、pipeline三个模块，可以通过扩展这些接口实现强大的扩展功能。如可以通过多个Spider实现多线程抓取；可以通过扩展schedular实现断点续传乃至于分布式爬虫；可以通过扩展pipeline实现业务可定制的持久化功能。
+	git clone https://github.com/code4craft/webmagic.git
+	cd webmagic
+	mvn clean install
+
+安装后，在项目中添加对应的依赖即可使用webmagic：
+
+		<dependency>
+            <groupId>us.codecraft</groupId>
+            <artifactId>webmagic-core</artifactId>
+            <version>0.2.0</version>
+        </dependency>
+		<dependency>
+            <groupId>us.codecraft</groupId>
+            <artifactId>webmagic-extension</artifactId>
+            <version>0.2.0</version>
+        </dependency>
+
+#### 项目结构
 	
-------
+webmagic主要包括两个包：
 
-###Get Started
+* **webmagic-core**
+	
+	webmagic核心部分，只包含爬虫基本模块和基本抽取器。webmagic-core的目标是成为网页爬虫的一个教科书般的实现。
+	
+* **webmagic-extension**
 	
-webmagic定制的核心是PageProcessor接口。一个最简单的webmagic爬虫例子是这样的：
+	webmagic的扩展模块，提供一些更方便的编写爬虫的工具。包括注解格式定义爬虫、JSON、分布式等支持。
+	
+webmagic还包含两个可用的扩展包，因为这两个包都依赖了比较重量级的工具，所以从主要包中抽离出来：
+
+* **webmagic-saxon**
+
+	webmagic与Saxon结合的模块。Saxon是一个XPath、XSLT的解析工具，webmagic依赖Saxon来进行XPath2.0语法解析支持。
 
-	Spider.me().processor(new SimplePageProcessor("http://my.oschina.net/", "http://my.oschina.net/*/blog/*")).run();
+* **webmagic-selenium**
+
+	webmagic与Selenium结合的模块。Selenium是一个模拟浏览器进行页面渲染的工具，webmagic依赖Selenium进行动态页面的抓取。
 	
-其中SimplePageProcessor实现如下：
+在项目中，你可以根据需要依赖不同的包。
 
-    public class SimplePageProcessor implements PageProcessor {
+### 不使用maven
 
-        private String urlPattern;
+不使用maven的用户，可以下载这个二进制打包版本(感谢[oschina](http://www.oschina.net/))：
 
-        private static final String UA = "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_7_2) AppleWebKit/537.31 (KHTML, like Gecko) Chrome/26.0.1410.65 Safari/537.31";
+	git clone http://git.oschina.net/flashsword20/webmagic-bin.git
 
-        private Site site;
+在**bin/lib**目录下，有项目依赖的所有jar包，直接在IDE里import即可。
 
-        public SimplePageProcessor(String startUrl, String urlPattern) {
-            this.site = Site.me().setStartUrl(startUrl).
-                    setDomain(UrlUtils.getDomain(startUrl)).setUserAgent(UA);
-            this.urlPattern = "("+urlPattern.replace(".","\\.").replace("*","[^\"'#]*")+")";
+### 第一个爬虫
 
-        }
+#### 定制PageProcessor
+
+PageProcessor是webmagic-core的一部分，定制一个PageProcessor即可实现自己的爬虫逻辑。以下是抓取osc博客的一段代码：
+
+    public class OschinaBlogPageProcesser implements PageProcessor {
+
+        private Site site = Site.me().setDomain("my.oschina.net")
+           .addStartUrl("http://my.oschina.net/flashsword/blog");
 
         @Override
         public void process(Page page) {
-            List<String> requests = page.getHtml().as().rs(urlPattern).toStrings();
-            page.addTargetRequests(requests);
-            page.putField("title", page.getHtml().x("//title"));
-            page.putField("content", page.getHtml().sc());
+            List<String> links = page.getHtml().links().regex("http://my\\.oschina\\.net/flashsword/blog/\\d+").all();
+            page.addTargetRequests(links);
+            page.putField("title", page.getHtml().xpath("//div[@class='BlogEntity']/div[@class='BlogTitle']/h1").toString());
+            page.putField("content", page.getHtml().$("div.content").toString());
+            page.putField("tags",page.getHtml().xpath("//div[@class='BlogTags']/a/text()").all());
         }
 
         @Override
         public Site getSite() {
             return site;
+
+        }
+
+        public static void main(String[] args) {
+            Spider.create(new OschinaBlogPageProcesser())
+                 .pipeline(new ConsolePipeline()).run();
         }
     }
 
----
+这里通过page.addTargetRequests()方法来增加要抓取的URL，并通过page.putField()来保存抽取结果。page.getHtml().xpath()则是按照某个规则对结果进行抽取，这里抽取支持链式调用。调用结束后，toString()表示转化为单个String，all()则转化为一个String列表。
 
-TODO
+Spider是爬虫的入口类。Pipeline是结果输出和持久化的接口，这里ConsolePipeline表示结果输出到控制台。
 
+执行这个main方法，即可在控制台看到抓取结果。webmagic默认有3秒抓取间隔，请耐心等待。
 
-		public class OschinaBlogPageProcesser implements PageProcessor {
+#### 使用注解
 
-        @Override
-        public void process(Page page) {
-            List<String> strings = page.getHtml().rs("<a[^<>]*href=[\"']{1}(http://my\\.oschina\\.net/\\w+/blog/\\d+)[\"']{1}").toStrings();
-            page.addTargetRequests(strings);
-            page.putField("title", page.getHtml().xs("//div[@class='BlogEntity']/div[@class='BlogTitle']/h1"));
-            page.putField("content", page.getHtml().sc());
-            page.putField("author", page.getUrl().r("my\\.oschina\\.net/(\\w+)/blog/\\d+"));
-        }
+webmagic-extension包括了注解方式编写爬虫的方法，只需基于一个POJO增加注解即可完成一个爬虫。以下仍然是抓取oschina博客的一段代码，功能与OschinaBlogPageProcesser完全相同：
 
-        @Override
-        public Site getSite() {
-            return Site.me().setDomain("my.oschina.net").setStartUrl("http://www.oschina.net/").
-                    setUserAgent("Mozilla/5.0 (Macintosh; Chrome/26.0.1410.65 Safari/537.31");
-        	}
-    	}
+	@TargetUrl("http://my.oschina.net/flashsword/blog/\\d+")
+	public class OschinaBlog {
+
+	    @ExtractBy("//title")
+	    private String title;
+
+	    @ExtractBy(value = "div.BlogContent",type = ExtractBy.Type.Css)
+	    private String content;
+
+	    @ExtractBy(value = "//div[@class='BlogTags']/a/text()", multi = true)
+	    private List<String> tags;
+
+	    public static void main(String[] args) {
+	        OOSpider.create(
+	        	Site.me().addStartUrl("http://my.oschina.net/flashsword/blog"),
+				new ConsolePageModelPipeline(), OschinaBlog.class).run();
+	    }
+	}
+
+这个例子定义了一个Model类，Model类的字段'title'、'content'、'tags'均为要抽取的属性。这个类在Pipeline里是可以复用的。
+
+### 详细文档
+
+见[webmagic manual.md](https://github.com/code4craft/webmagic/blob/master/webmagic%20manual.md)。
+
+### 示例
+
+webmagic-samples目录里有一些定制PageProcessor以抽取不同站点的例子。
+
+作者还有一个使用webmagic进行抽取并持久化到数据库的项目[JobHunter](http://git.oschina.net/flashsword20/jobhunter)。这个项目整合了Spring，自定义了Pipeline，使用mybatis进行数据持久化。

+
+增加了webmagic-extension模块。
+
+增加了注解方式支持，可以通过POJO+注解的方式编写一个爬虫，更符合Java开发习惯。以下是抓取一个博客的完整代码：
+
+    @TargetUrl("http://my.oschina.net/flashsword/blog/\\d+")
+    public class OschinaBlog {
+
+        @ExtractBy("//title")

+webmagic使用手册
+------
+>webmagic是一个开源的Java垂直爬虫框架，目标是简化爬虫的开发流程，让开发者专注于逻辑功能的开发。webmagic的核心非常简单，但是覆盖爬虫的整个流程，也是很好的学习爬虫开发的材料。
+
+>web爬虫是一种技术，webmagic致力于将这种技术的实现成本降低，但是出于对资源提供者的尊重，webmagic不会做反封锁的事情，包括：验证码破解、代理切换、自动登录、抓取静态资源等。
+
+>作者黄亿华([code4crafter@gmail.com](code4crafter@gmail.com))目前就职于大众点评，曾经在前公司进行过一年的垂直爬虫的开发，webmagic就是为了解决爬虫开发的一些重复劳动而产生的框架。
+
+>webmagic的架构和设计参考了以下两个项目，感谢以下两个项目的作者：
+
+>python爬虫 **scrapy** [https://github.com/scrapy/scrapy](https://github.com/scrapy/scrapy)
+
+>Java爬虫 **Spiderman** [https://gitcafe.com/laiweiwei/Spiderman](https://gitcafe.com/laiweiwei/Spiderman)
+
+>webmagic遵循[Apache 2.0协议](http://www.apache.org/licenses/LICENSE-2.0.html)，你可以自由进行使用和修改。有使用不便或者问题，欢迎在github[提交issue](https://github.com/code4craft/webmagic/issues)，或者在[oschina讨论模块](http://www.oschina.net/question)提问。
+
+<div style="page-break-after:always"></div>
+
+
+## 快速开始
+
+### 使用maven
+
+webmagic使用maven管理依赖，你可以直接下载webmagic源码进行编译：
+
+	git clone https://github.com/code4craft/webmagic.git
+	mvn clean install
+
+安装后，在项目中添加对应的依赖即可使用webmagic：
+
+		<dependency>
+            <groupId>us.codecraft</groupId>
+            <artifactId>webmagic-core</artifactId>
+            <version>0.2.0</version>
+        </dependency>
+		<dependency>
+            <groupId>us.codecraft</groupId>
+            <artifactId>webmagic-extension</artifactId>
+            <version>0.2.0</version>
+        </dependency>
+
+#### 项目结构
+	
+webmagic主要包括两个包：
+
+* **webmagic-core**
+	
+	webmagic核心部分，只包含爬虫基本模块和基本抽取器。webmagic-core的目标是成为网页爬虫的一个教科书般的实现。
+	
+* **webmagic-extension**
+	
+	webmagic的扩展模块，提供一些更方便的编写爬虫的工具。包括注解格式定义爬虫、JSON、分布式等支持。
+	
+webmagic还包含两个可用的扩展包，因为这两个包都依赖了比较重量级的工具，所以从主要包中抽离出来：
+
+* **webmagic-saxon**
+
+	webmagic与Saxon结合的模块。Saxon是一个XPath、XSLT的解析工具，webmagic依赖Saxon来进行XPath2.0语法解析支持。
+
+* **webmagic-selenium**
+
+	webmagic与Selenium结合的模块。Selenium是一个模拟浏览器进行页面渲染的工具，webmagic依赖Selenium进行动态页面的抓取。
+	
+在项目中，你可以根据需要依赖不同的包。
+
+### 不使用maven
+
+不使用maven的用户，可以下载这个二进制打包版本(感谢[oschina](http://www.oschina.net/))：
+
+	git clone http://git.oschina.net/flashsword20/webmagic-bin.git
+
+在**bin/lib**目录下，有项目依赖的所有jar包，直接在IDE里import即可。
+
+### 第一个爬虫
+
+#### 定制PageProcessor
+
+PageProcessor是webmagic-core的一部分，定制一个PageProcessor即可实现自己的爬虫逻辑。以下是抓取osc博客的一段代码：
+
+    public class OschinaBlogPageProcesser implements PageProcessor {
+
+        private Site site = Site.me().setDomain("my.oschina.net")
+           .addStartUrl("http://my.oschina.net/flashsword/blog");
+
+        @Override
+        public void process(Page page) {
+            List<String> links = page.getHtml().links().regex("http://my\\.oschina\\.net/flashsword/blog/\\d+").all();
+            page.addTargetRequests(links);
+            page.putField("title", page.getHtml().xpath("//div[@class='BlogEntity']/div[@class='BlogTitle']/h1").toString());
+            page.putField("content", page.getHtml().$("div.content").toString());
+            page.putField("tags",page.getHtml().xpath("//div[@class='BlogTags']/a/text()").all());
+        }
+
+        @Override
+        public Site getSite() {
+            return site;
+
+        }
+
+        public static void main(String[] args) {
+            Spider.create(new OschinaBlogPageProcesser())
+                 .pipeline(new ConsolePipeline()).run();
+        }
+    }
+
+这里通过page.addTargetRequests()方法来增加要抓取的URL，并通过page.putField()来保存抽取结果。page.getHtml().xpath()则是按照某个规则对结果进行抽取，这里抽取支持链式调用。调用结束后，toString()表示转化为单个String，all()则转化为一个String列表。
+
+Spider是爬虫的入口类。Pipeline是结果输出和持久化的接口，这里ConsolePipeline表示结果输出到控制台。
+
+执行这个main方法，即可在控制台看到抓取结果。webmagic默认有3秒抓取间隔，请耐心等待。
+
+#### 使用注解
+
+webmagic-extension包括了注解方式编写爬虫的方法，只需基于一个POJO增加注解即可完成一个爬虫。以下仍然是抓取oschina博客的一段代码，功能与OschinaBlogPageProcesser完全相同：
+
+	@TargetUrl("http://my.oschina.net/flashsword/blog/\\d+")
+	public class OschinaBlog {
+
+	    @ExtractBy("//title")
+	    private String title;
+
+	    @ExtractBy(value = "div.BlogContent",type = ExtractBy.Type.Css)
+	    private String content;
+
+	    @ExtractBy(value = "//div[@class='BlogTags']/a/text()", multi = true)
+	    private List<String> tags;
+
+	    public static void main(String[] args) {
+	        OOSpider.create(
+	        	Site.me().addStartUrl("http://my.oschina.net/flashsword/blog"),
+				new ConsolePageModelPipeline(), OschinaBlog.class).run();
+	    }
+	}
+
+这个例子定义了一个Model类，Model类的字段'title'、'content'、'tags'均为要抽取的属性。这个类在Pipeline里是可以复用的。
+
+注解的详细使用方式见后文中得webmagic-extension注解模块。

+
+
+## webmagic-core
+
+webmagic-core是爬虫的核心框架，只包括一个爬虫各功能模块的核心功能。webmagic-core的目标是成为网页爬虫的一个教科书般的实现。
+
+此节部分内容摘自作者的博文
+[webmagic的设计机制及原理-如何开发一个Java爬虫](http://my.oschina.net/flashsword/blog/145796)。
+
+### webmagic-core的模块划分
+
+webmagic-core参考了scrapy的模块划分，分为Spider(整个爬虫的调度框架)、Downloader(页面下载)、PageProcessor(链接提取和页面分析)、Scheduler(URL管理)、Pipeline(离线分析和持久化)几部分。只不过scrapy通过middleware实现扩展，而webmagic则通过定义这几个接口，并将其不同的实现注入主框架类Spider来实现扩展。
+
+![image](http://code4craft.github.io/images/posts/webmagic.png)
+<div style="page-break-after:always"></div>
+
+#### Spider类(核心调度)
+
+**Spider**是爬虫的入口类，Spider的接口调用采用了链式的API设计，其他功能全部通过接口注入Spider实现，下面是启动一个比较复杂的Spider的例子。
+
+    Spider.create(sinaBlogProcessor)
+	.scheduler(new FileCacheQueueScheduler("/data/temp/webmagic/cache/"))
+	.pipeline(new FilePipeline())
+	.thread(10).run();	
+
+
+Spider的核心处理流程非常简单，代码如下：
+
+    <!-- lang: java -->
+    private void processRequest(Request request) {
+        Page page = downloader.download(request, this);
+        if (page == null) {
+            sleep(site.getSleepTime());
+            return;
+        }
+        pageProcessor.process(page);
+        addRequest(page);
+        for (Pipeline pipeline : pipelines) {
+            pipeline.process(page, this);
+        }
+        sleep(site.getSleepTime());
+    }
+    
+#### PageProcessor(页面分析及链接抽取)
+
+页面分析是垂直爬虫中需要定制的部分。在webmagic-core里，通过实现**PageProcessor**接口来实现定制爬虫。PageProcessor有两个核心方法：public void process(Page page)和public Site getSite() 。
+
+* public void process(Page page)
+
+	通过对**Page**对象的操作，实现爬虫逻辑。Page对象包括两个最重要的方法：addTargetRequests()可以添加URL到待抓取队列，put()可以将结果保存供后续处理。
+	Page的数据可以通过Page.getHtml()和Page.getUrl()获取。
+
+* public Site getSite()
+	
+	**Site**对象定义了爬虫的域名、起始地址、抓取间隔、编码等信息。
+
+**Selector**是webmagic为了简化页面抽取开发的独立模块，是webmagic-core的主要着力点。这里整合了CSS Selector、XPath和正则表达式，并可以进行链式的抽取。
+		
+    <!-- lang: java -->
+    //content是用别的爬虫工具抽取到的正文
+    List<String> links = page.getHtml()
+    .$("div.title")  //css 选择，Java里虽然很少有$符号出现，不过貌似$作为方法名是合法的
+    .xpath("//@href")  //提取链接
+    .regex(".*blog.*") //正则匹配过滤
+    .all(); //转换为string列表
+
+webmagic包括一个对于页面正文的自动抽取的类**SmartContentSelector**。相信用过Evernote Clearly都会对其自动抽取正文的技术印象深刻。这个技术又叫**Readability**。当然webmagic对Readability的实现还比较粗略，但是仍有一些学习价值。
+
+基于Saxon，webmagic提供了XPath2.0语法的支持。XPath2.0语法支持内部函数、逻辑控制等，是一门完整的语言，如果你熟悉XPath2.0语法，倒是不妨一试(需要引入**webmagic-saxon**包)。
+
+**webmagic-samples**包里有一些为某个站点定制的PageProcessor，供学习之用。
+
+#### Downloader(页面下载)
+
+**Downloader**是webmagic中下载页面的接口，主要方法：
+
+* public Page download(Request request, Task task) 
+	
+	**Request**对象封装了待抓取的URL及其他信息，而Page则包含了页面下载后的Html及其他信息。Task是一个包装了任务对应的Site信息的抽象接口。
+	
+* public void setThread(int thread)
+	
+	因为Downloader一般会涉及连接池等功能，而这些功能与多线程密切相关，所以定义了此方法。
+
+目前有几个Downloader的实现：
+
+* HttpClientDownloader
+	
+	集成了**Apache HttpClient**的Downloader。Apache HttpClient(4.0后整合到HttpCompenent项目中)是强大的Java http下载器，它支持自定义HTTP头(对于爬虫比较有用的就是User-agent、cookie等)、自动redirect、连接复用、cookie保留、设置代理等诸多强大的功能。
+
+* SeleniumDownloader
+	
+	对于一些Javascript动态加载的网页，仅仅使用http模拟下载工具，并不能取到页面的内容。这方面的思路有两种：一种是抽丝剥茧，分析js的逻辑，再用爬虫去重现它；另一种就是：内置一个浏览器，直接获取最后加载完的页面。**webmagic-selenium**包中整合了Selenium到SeleniumDownloader，可以直接进行动态加载页面的抓取。
+
+#### Scheduler(URL管理)
+
+**Scheduler**是webmagic的管理模块，通过实现Scheduler可以定制自己的URL管理器。Scheduler包括两个主要方法：
+
+* public void push(Request request,Task task)
+	
+	将待抓取URL加入Scheduler。Request对象是对URL的一个封装，还包括优先级、以及一个供存储数据的Map。Task仍然用于区分不同任务，在多个任务公用一个Scheduler时可以此进行区分。
+
+* public Request poll(Task task)
+	
+	从Scheduler里取出一条请求，并进行后续执行。
+
+webmagic目前有三个Scheduler的实现：
+
+* QueueScheduler
+	
+	一个简单的内存队列，速度较快，并且是线程安全的。
+	
+* FileCacheQueueScheduler
+	
+	使用文件保存队列，它可以用于耗时较长的下载任务，在任务中途停止后(手动停止或者程序崩溃)，下次执行仍然从中止的URL开始继续爬取。
+	
+* RedisScheduler
+	
+	使用redis存储URL队列。通过使用同一台redis服务器存储URL，webmagic可以很容易的在多机部署，从而达到分布式爬虫的效果。
+
+#### Pipeline(后续处理和持久化)
+
+**Pipeline**是最终抽取结果进行输出和持久化的接口。它只包括一个方法：
+
+* public void process(ResultItems resultItems,Task task)
+	
+	**ResultItems**是集成了抽取结果的对象。通过ResultItems.get(key)可以获取抽取结果。Task同样是用于区分不同任务的对象。
+	
+webmagic包括以下几个Pipeline的实现：
+
+* ConsolePipeline
+	
+	直接输出结果到控制台，测试时使用。
+	
+* FilePipeline
+	
+	输出结果到文件，每个URL单独保存到一个页面，以URL的MD5结果作为文件名。通过构造函数`public FilePipeline(String path)`定义存储路径，**以下使用文件持久化的类，多数都使用此方法指定路径**。
+	
+* JsonFilePipeline
+	
+	以JSON输出结果到文件(.json后缀)，其他与FilePipeline相同。
+
+webmagic目前不支持持久化到数据库，但是结合其他工具，持久化到数据库也是很容易的。这里不妨看一下[webmagic结合JFinal持久化到数据库的一段代码](http://www.oschina.net/code/snippet_190591_23456)。因为JFinal目前还不支持maven，所以这段代码并没有放到webmagic-samples里来。
+
+<div style="page-break-after:always"></div>
+
+## webmagic-extension
+
+webmagic-extension是为了开发爬虫更方便而实现的一些功能模块。这些功能完全基于webmagic-core的框架，包括注解形式编写爬虫、分页、分布式等功能。
+
+### 注解模块
+
+webmagic-extension包括注解模块。为什么会有注解方式？
+
+因为PageProcessor的方式灵活、强大，但是没有解决两个问题：
+
+* 对于一个站点，如果想抓取多种格式的URL，那么必须在PageProcesser中写判断逻辑，代码难以管理。
+* 抓取结果没有对应Model，并不符合Java程序开发习惯，与一些框架也无法很好整合。
+
+注解的核心是Model类，本身是一个POJO，这个Model类用于传递、保存页面最终抓取结果数据。注解方式直接将抽取与数据绑定，以便于编写和维护。
+
+注解方式其实也是通过一个PageProcessor的实现--ModelPageProcessor完成，因此对webmagic-core代码没有任何影响。仍然以抓取OschinaBlog的程序为例：
+
+	@TargetUrl("http://my.oschina.net/flashsword/blog/\\d+")
+	public class OschinaBlog {
+
+	    @ExtractBy("//title")
+	    private String title;
+
+	    @ExtractBy(value = "div.BlogContent",type = ExtractBy.Type.Css)
+	    private String content;
+
+	    @ExtractBy(value = "//div[@class='BlogTags']/a/text()", multi = true)
+	    private List<String> tags;
+
+	    public static void main(String[] args) {
+	        OOSpider.create(
+	        	Site.me().addStartUrl("http://my.oschina.net/flashsword/blog"),
+				new ConsolePageModelPipeline(), OschinaBlog.class).run();
+	    }
+	}
+
+注解部分包括以下内容：
+
+* #### TargetUrl
+
+	"TargetUrl"表示这个Model对应要抓取的URL，它包含两层意思：符合这个条件的URL会被加入抓取队列；符合这个条件的URL会被这个Model抓取。TargetUrl可以**sourceRegion**指定提取URL的区域(仅支持XPath)。
+	
+	TargetUrl使用了正则表达式，匹配 "http://my.oschina.net/flashsword/blog/150039" 格式的URL。webmagic对正则表达式进行了修改，"."仅表示字符"."而不代表任意字符，而"\*"则代表了".\*"，例如"http://\*.oschina.net/\*"代表了oschina所有的二级域名下的URL。
+	
+	与TargetUrl相似的还有**HelpUrl**，HelpUrl表示：仅仅抓取该URL用作链接提取，并不对它进行内容抽取。例如博客正文页对应TargetUrl，而列表页则对应HelpUrl。
+
+* #### ExtractBy	
+
+	* #### 用于字段
+
+		"ExtractBy"可用于类以及字段。用于字段时，定义了字段抽取的规则。抽取的规则默认使用[**XPath**](http://www.w3school.com.cn/xpath/)，也可以选择使用CSS Selector、正则表达式(通过设置type)。
+	
+		ExtractBy还有几个扩展属性。**multi**表示是否抽取列表，当然，设置为multi时，你需要一个List字段去容纳它。**notnull**则表示，此字段不允许为null，若为null则放弃整个对象。
+
+	* #### 用于类	
+		
+		"ExtractBy"用于类时，则限定了字段抽取的区域。用于类时仍支持multi，multi则表示一个页面可以抽取到多个对象。
+
+	* #### ExtractByRaw & ExtractByUrl
+	
+		在类使用"ExtractBy"修饰后，字段的"ExtractBy"使用的是其抽取的结果，如果仍然想要抽取原HTML，可以使用"ExtractByRaw"。与此类似的还有"ExtractByUrl"，表示从URL中抽取信息。ExtractByUrl只支持正则表达式。
+
+	* #### ExtractBy2 ExtractBy3	
+		
+		"ExtractBy"、"ExtractByRaw"支持链式抽取，通过增加注解"ExtractBy2"、"ExtractBy3"实现。
+		
+* #### AfterExtractor
+
+	AfterExtractor接口是对注解方式抽取能力不足的补充。实现AfterExtractor接口后，会在**使用注解方式填充完字段后**调用**afterProcess()**方法，在这个方法中可以直接访问已抽取的字段、补充需要抽取的字段，甚至做一些简单的输出和持久化操作(并不是很建议这么做)。这部分可以参考[webmagic结合JFinal持久化到数据库的一段代码](http://www.oschina.net/code/snippet_190591_23456)。
+
+* #### OOSpider
+	OOSpider是注解式爬虫的入口，这里调用**create()**方法将OschinaBlog这个类加入到爬虫的抽取中，这里是可以传入多个类的，例如：
+	
+		OOSpider.create(
+			Site.me().addStartUrl("http://www.oschina.net"),
+			new ConsolePageModelPipeline(),
+			OschinaBlog.clas,OschinaAnswer.class).run();
+		
+	OOSpider会根据TargetUrl调用不同的Model进行解析。
+
+* #### PageModelPipeline
+	可以通过定义PageModelPipeline来选择结果输出方式。这里new ConsolePageModelPipeline()是PageModelPipeline的一个实现，会将结果输出到控制台。
+	
+* #### 分页
+
+	处理单项数据分页(例如单条新闻多个页面)是爬虫一个比较头疼的问题。webmagic目前对于分页的解决方案是：在注解模式下，Model通过实现**PagedModel**接口，并引入PagedPipeline作为第一个Pipeline来实现。具体可以参考webmagic-samples中抓取网易新闻的代码：**us.codecraft.webmagic.model.samples.News163**。
+	
+	关于分页，这里有一篇对于webmagic分页实现的详细说明的文章[关于爬虫实现分页的一些思考](http://my.oschina.net/flashsword/blog/150039)。
+	目前分页功能还没有分布式实现，如果实现RedisScheduler进行分布式爬取，请不要使用分页功能。
+	
+### 分布式
+
+webmagic-extension中，通过redis来管理URL，达到分布式的效果。但是对于分布式爬虫，仅仅程序能够分布式运行，还满足不了大规模抓取的需要，webmagic可能后期会加入一些任务管理和监控的功能，也欢迎各位用户为webmagic提交代码，做出贡献。

-            "<p> 最近初学Python, 语法大概熟悉了之后就开始拿web.py做点小东西，web.py非常轻量，用起来感觉很舒服。但不过无论什么语言或者框架，web开发中有一个最大烦人之处就是表单验证，web.py提供了web.form来进行表单验证的统一处理，这个东西虽然用起来很简单，但是感觉还是不太合心意，首先这套验证机制跟web.py框架耦合的程度太高，而自己的架构是这样的，业务逻辑跟web逻辑完全分离，web仅仅是交互形式的一种，即使添加客户端C/S形式的服务或者是向开发者提供API，业务逻辑也是完全可用，不需要修改，这样对用户输入的验证是属于业务逻辑这一块，不应该跟web表单耦合在一起；另外感觉web.py这套东西还是有些简单，只支持每个表单的正则验证和最后表单提交的整体验证，而很多时候可能需要对用户进行丰富的错误提示，比如针对用户名的错误会具体到是不能为空还是长度错误或者格式错误等, 这个用web.py的form验证就感觉很别扭了。于是就决定自己设计一个用户输入的验证方案。 </p> \n" +
-            "<h2> 设计 </h2> \n" +
-            "<p> web项目的开发多数都是遵循这么一个结构的设计，即DAO-&gt;Service-&gt;Controller-&gt;View, 按我前面说的，对用户的输入验证应是发生在Service这一层上，这一层的设计是接受用户输入的参数，然后进行验证处理，再进行业务相关的计算，最后输入结果。每个Service接口都应该返回一个结果，我一般都会把这个结果的内容抽象成一个一致类型的对象: </p> \n" +
-            "<pre class=\"brush:python; toolbar: true; auto-links: false;\">class Result(object):\n" +
-            "    \n" +
-            "    u''' 操作结果抽象 '''\n" +
-            "    \n" +
-            "    def __init__(self, code, value=None):\n" +
-            "       &nbsp;self.code = code   #操作结果代号\n" +
-            "        self.value = value #操作结果值\n" +
-            "        \n" +
-            "    def __str__(self):\n" +
-            "        return &quot;operation result, code: %s, value: %s&quot; % (self.code, self.value)</pre> \n" +
-            "<p> 这个结果对象包含两个属性，一个是操作结果的代码，一个是操作的值，举个例子，比如用户注册的接口，如果注册成功，那么就会返回一个这样的Result对象，code属性是'success', value属性是新注册用户分配的ID，如果用户名已经被占用，那么code属性就是'username_exised', value属性的值是None。客户端拿到code属性的值可以做响应的处理，如果是直接面向最终用户的web应用，那么就会去找到这个code对应的错误信息来展示给用户，所有的错误信息我是组织在一个单独的Python模块中(opresult.py): </p> \n" +
-            "<pre class=\"brush:python; toolbar: true; auto-links: false;\">reg = {\n" +
-            "       'success':u'注册成功',\n" +
-            "       'username_empty':u'用户名不得为空',\n" +
-            "       'username_format':u'用户名必须只能有数字、字母下划线组成',\n" +
-            "       'username_length':u'用户名长度必须在5到10个字符之间',\n" +

-            "       }</pre> reg是注册的接口名称，这样客户端通过接口名称和code就可以获取对应的提示。 \n" +
-            "<p> 由此，用户输入验证就是要把接口参数同这些code联系起来。对于参数验证，Python有天生的语言优势，那就是装饰器。一开始就想到了使用装饰器来描述参数验证需求，但这个装饰器需要哪些信息？怎么个形式?这个得从表单验证的需求开始看起，个人总结表单验证大抵不过这些判断条件： </p> \n" +
-            "<p> 1. 是否允许为空 </p> \n" +
-            "<p> 2. 长度限制:比如密码的长度一般会不允许少于多少位 </p> \n" +
-            "<p> 3. 格式限制:比如Email地址,需要正则判断 </p> \n" +
-            "<p> 4. 逻辑限制：比如注册时判断用户名是否已经存在 </p> \n" +
-            "<p> 初步根据这些判断条件设计出这么一个方案: </p> \n" +

-            "                    'min-length':5, 'max-length':10, \n" +
-            "                    'check_logic':[check_username_usable]},\n" +

-            "def reg(username, password, repassword):\n" +
-            "    ....</pre> \n" +
-            "<p> 每一个参数使用一个字典来描述验证信息, allow_empty是表示是否为空，regex为验证的正则表达式，min-length和max-length用来描述长度，check_logic用来配置其他的验证逻辑。然后如何把这些验证结果同code进行匹配呢？最开始是在这个验证信息的字典中有一项'code':{'allow_empty':'username_empty'}通过这样的形式去匹配错误提示，但是感觉这样整的这个参数太复杂了（感觉现在已经挺复杂了- -b）,于是决定这个地方使用约定优于配置的形式，code的值为'参数名_错误类型'的形式，比如allow_empty如果验证了为空，那么会自动返回名为username_empty的code,如果是一些额外的处理逻辑呢？没法做约定，怎么办？那么就约定这些检测函数返回一个元组，第一个元素为一个bool值，表示成功失败，第二个参数为code,表示失败原因,比如判断两次密码是否输入一致的那个lambda: </p> \n" +
