# Compute Engine API . forwardingRules

## Instance Methods

Retrieves an aggregated list of forwarding rules.

Retrieves the next page of results.

Close httplib2 connections.

Deletes the specified ForwardingRule resource.

Returns the specified ForwardingRule resource.

Creates a ForwardingRule resource in the specified project and region using the data included in the request.

Retrieves a list of ForwardingRule resources available to the specified project and region.

Retrieves the next page of results.

Updates the specified forwarding rule with the data included in the request. This method supports PATCH semantics and uses the JSON merge patch format and processing rules. Currently, you can only patch the network_tier field.

Sets the labels on the specified resource. To learn more about labels, read the Labeling Resources documentation.

Changes target URL for forwarding rule. The new target should be of the same type as the old target.

Returns permissions that a caller has on the specified resource.

### Method Details

`aggregatedList(project, filter=None, includeAllScopes=None, maxResults=None, orderBy=None, pageToken=None, returnPartialSuccess=None, x__xgafv=None)`

    Retrieves an aggregated list of forwarding rules.

    Args:
      project: string, Project ID for this request. (required)
      filter: string, A filter expression that filters resources listed in the response. The expression must specify the field name, a comparison operator, and the value that you want to use for filtering. The value must be a string, a number, or a boolean. The comparison operator must be either `=`, `!=`, `>`, or `<`. For example, if you are filtering Compute Engine instances, you can exclude instances named `example-instance` by specifying `name != example-instance`. You can also filter nested fields. For example, you could specify `scheduling.automaticRestart = false` to include instances only if they are not scheduled for automatic restarts. You can use filtering on nested fields to filter based on resource labels. To filter on multiple expressions, provide each separate expression within parentheses. For example: ``` (scheduling.automaticRestart = true) (cpuPlatform = "Intel Skylake") ``` By default, each expression is an `AND` expression. However, you can include `AND` and `OR` expressions explicitly. For example: ``` (cpuPlatform = "Intel Skylake") OR (cpuPlatform = "Intel Broadwell") AND (scheduling.automaticRestart = true) ```
      includeAllScopes: boolean, Indicates whether every visible scope for each scope type (zone, region, global) should be included in the response. For new resource types added after this field, the flag has no effect as new resource types will always include every visible scope for each scope type in response. For resource types which predate this field, if this flag is omitted or false, only scopes of the scope types where the resource type is expected to be found will be included.
      maxResults: integer, The maximum number of results per page that should be returned. If the number of available results is larger than `maxResults`, Compute Engine returns a `nextPageToken` that can be used to get the next page of results in subsequent list requests. Acceptable values are `0` to `500`, inclusive. (Default: `500`)
      orderBy: string, Sorts list results by a certain order. By default, results are returned in alphanumerical order based on the resource name. You can also sort results in descending order based on the creation timestamp using `orderBy="creationTimestamp desc"`. This sorts results based on the `creationTimestamp` field in reverse chronological order (newest result first). Use this to sort resources like operations so that the newest operation is returned first. Currently, only sorting by `name` or `creationTimestamp desc` is supported.
      pageToken: string, Specifies a page token to use. Set `pageToken` to the `nextPageToken` returned by a previous list request to get the next page of results.
      returnPartialSuccess: boolean, Opt-in for partial success behavior which provides partial results in case of failure. The default value is false.
      x__xgafv: string, V1 error format.
        Allowed values
          1 - v1 error format
          2 - v2 error format

    Returns:

The fingerprint is initially generated by Compute Engine and changes after every request to modify or update labels. You must always provide an up-to-date fingerprint hash in order to update or change labels, otherwise the request will fail with error 412 conditionNotMet.

If its filterMatchCriteria is set to MATCH_ALL, then all of its filterLabels must match with corresponding labels provided in the metadata. If multiple metadataFilters are specified, all of them need to be satisfied in order to be considered a match. metadataFilters specified here will be applifed before those specified in the UrlMap that this ForwardingRule references. metadataFilters only applies to Loadbalancers that have their loadBalancingScheme set to INTERNAL_SELF_MANAGED.

If its filterMatchCriteria is set to MATCH_ALL, then all of its filterLabels must match with corresponding labels provided in the metadata. An example for using metadataFilters would be: if loadbalancing involves Envoys, they will only receive routing configuration when values in metadataFilters match values supplied in of their XDS requests to loadbalancers.

`aggregatedList_next(previous_request, previous_response)`

    Retrieves the next page of results.

    Args:
      previous_request: The request for the previous page. (required)
      previous_response: The response from the request for the previous page. (required)

    Returns:
      A request object that you can call 'execute()' on to request the next
      page. Returns None if there are no more items in the collection.

`close()`

    Close httplib2 connections.

`delete(project, region, forwardingRule, requestId=None, x__xgafv=None)`

    Deletes the specified ForwardingRule resource.

    Args:
      project: string, Project ID for this request. (required)
      region: string, Name of the region scoping this request. (required)
      forwardingRule: string, Name of the ForwardingRule resource to delete. (required)
      requestId: string, An optional request ID to identify requests. Specify a unique request ID so that if you must retry your request, the server will know to ignore the request if it has already been completed. For example, consider a situation where you make an initial request and the request times out. If you make the request again with the same request ID, the server can check if original operation with the same request ID was received, and if so, will ignore the second request. This prevents clients from accidentally creating duplicate commitments. The request ID must be a valid UUID with the exception that zero UUID is not supported ( 00000000-0000-0000-0000-000000000000).

      requestId: string, An optional request ID to identify requests. Specify a unique request ID so that if you must retry your request, the server will know to ignore the request if it has already been completed. For example, consider a situation where you make an initial request and the request times out. If you make the request again with the same request ID, the server can check if original operation with the same request ID was received, and if so, will ignore the second request. This prevents clients from accidentally creating duplicate commitments. The request ID must be a valid UUID with the exception that zero UUID is not supported ( 00000000-0000-0000-0000-000000000000).

`list(project, region, filter=None, maxResults=None, orderBy=None, pageToken=None, returnPartialSuccess=None, x__xgafv=None)`

    Retrieves a list of ForwardingRule resources available to the specified project and region.

    Args:
      project: string, Project ID for this request. (required)
      region: string, Name of the region scoping this request. (required)
      filter: string, A filter expression that filters resources listed in the response. The expression must specify the field name, a comparison operator, and the value that you want to use for filtering. The value must be a string, a number, or a boolean. The comparison operator must be either `=`, `!=`, `>`, or `<`. For example, if you are filtering Compute Engine instances, you can exclude instances named `example-instance` by specifying `name != example-instance`. You can also filter nested fields. For example, you could specify `scheduling.automaticRestart = false` to include instances only if they are not scheduled for automatic restarts. You can use filtering on nested fields to filter based on resource labels. To filter on multiple expressions, provide each separate expression within parentheses. For example: ``` (scheduling.automaticRestart = true) (cpuPlatform = "Intel Skylake") ``` By default, each expression is an `AND` expression. However, you can include `AND` and `OR` expressions explicitly. For example: ``` (cpuPlatform = "Intel Skylake") OR (cpuPlatform = "Intel Broadwell") AND (scheduling.automaticRestart = true) ```
      maxResults: integer, The maximum number of results per page that should be returned. If the number of available results is larger than `maxResults`, Compute Engine returns a `nextPageToken` that can be used to get the next page of results in subsequent list requests. Acceptable values are `0` to `500`, inclusive. (Default: `500`)
      orderBy: string, Sorts list results by a certain order. By default, results are returned in alphanumerical order based on the resource name. You can also sort results in descending order based on the creation timestamp using `orderBy="creationTimestamp desc"`. This sorts results based on the `creationTimestamp` field in reverse chronological order (newest result first). Use this to sort resources like operations so that the newest operation is returned first. Currently, only sorting by `name` or `creationTimestamp desc` is supported.
      pageToken: string, Specifies a page token to use. Set `pageToken` to the `nextPageToken` returned by a previous list request to get the next page of results.
      returnPartialSuccess: boolean, Opt-in for partial success behavior which provides partial results in case of failure. The default value is false.
      x__xgafv: string, V1 error format.
        Allowed values
          1 - v1 error format
          2 - v2 error format
