This excercise demonstrates how to process data that requires several http calls to produce the end result.
- Start by issuing a HTTP GET request to
http://localhost:3000/moviesand receiving a JSON array of movies. - For each movie POST a JSON object containing the
idandsynopsistohttp://localhost:3000/analyze. This will respond with a JSON array of recognized named entities in the synopsis. - Aggregate the result of all named entities for each movie and POST to
http://localhost:3000/checkwith the array of objects containingidandnamed_entities.
The /movies endpoint will respond with an Array of JavaScript objects like this:

Issue a POST request for every object in the JSON movie array. For example the movie above should look like this (note that it's only the id and synopsis fields):
{
"id": "771250004",
"synopsis": "THE HUNGER GAMES: CATCHING FIRE begins as Katniss Everdeen has returned home safe after winning the 74th Annual Hunger Games along with fellow tribute Peeta Mellark. Winning means that they must turn around and leave their family and close friends, embarking on a \"Victor's Tour\" of the districts. Along the way Katniss senses that a rebellion is simmering, but the Capitol is still very much in control as President Snow prepares the 75th Annual Hunger Games (The Quarter Quell) - a competition that could change Panem forever. (c) Lionsgate"
}
TIP: Make sure to specify the Content-Type header with value application/json.
POST a JavaScript Array containing the results of Step 2 for verification. Here's an example with just one entry. Make sure to POST every entry.
[{
"id": "771250004",
"named_entities":
[ "HUNGER",
"Katniss Everdeen",
"Annual Hunger Games",
"Peeta Mellark",
"Capitol",
"Snow",
"Annual Hunger Games",
"Panem" ]
}]
If your POST data is incorrect you will receive an object like this:
{
"results": [
"You must provide an array of objects with id and named_entities. Example [{ \"id\": \"1234\", \"named_entities\": [\"Joe\"] }]"
]
}
If your POST data is correct the response will simply be: Perfect! Good job!.
