Play REST API
This is the example project for Making a REST API in Play.
You need to download and install sbt for this application to run.
Once you have sbt installed, the following at the command prompt will start up Play in development mode:
Play will start up on the HTTP port at http://localhost:9000/. You don't need to deploy or reload anything -- changing any source code while the server is running will automatically recompile and hot-reload the application on the next HTTP request.
If you call the same URL from the command line, you’ll see JSON. Using httpie, we can execute the command:
http --verbose http://localhost:9000/v1/posts
and get back:
GET /v1/posts HTTP/1.1
Likewise, you can also send a POST directly as JSON:
http --verbose POST http://localhost:9000/v1/posts title="hello" body="world"
POST /v1/posts HTTP/1.1
The best way to see what Play can do is to run a load test. We've included Gatling in this test project for integrated load testing.
Start Play in production mode, by staging the application and running the play script:s
sbt stage cd target/universal/stage bin/play-rest-api-example -Dplay.crypto.secret=testing
Then you'll start the Gatling load test up (it's already integrated into the project):
For best results, start the gatling load test up on another machine so you do not have contending resources. You can edit the Gatling simulation, and change the numbers as appropriate.
Once the test completes, you'll see an HTML file containing the load test chart:
That will contain your load test results.
