= Gerrit Code Review - REST API Developers' Notes
This document is about developing the REST API. For details of the
actual APIs available in Gerrit, please see the
link:rest-api.html[REST API interface reference].
== Testing REST API Functionality
=== Basic Testing
Basic testing of REST API functionality can be done with `curl`:
curl http://localhost:8080/path/to/api/
By default, `curl` sends `GET` requests. To test APIs with `PUT`, `POST`,
or `DELETE`, an additional argument is required:
curl -X PUT http://localhost:8080/path/to/api/
curl -X POST http://localhost:8080/path/to/api/
curl -X DELETE http://localhost:8080/path/to/api/
=== Sending Data in the Request
Some REST APIs accept data in the request body of `PUT` and `POST` requests.
Test data can be included from a local file:
curl -X PUT -d@testdata.txt --header "Content-Type: application/json" http://localhost:8080/path/to/api/
Note that the `-d` option will remove the newlines from the content of the
local file. If the content should be sent as-is then use the `--data-binary`
option instead:
curl -X PUT --data-binary @testdata.txt --header "Content-Type: text/plain" http://localhost:8080/path/to/api/
Example to set a Gerrit project's link:rest-api-projects.html#set-project-description[description]:
curl -X PUT --user john:2LlAB3K9B0PF --data-binary @project-desc.txt --header "Content-Type: application/json; charset=UTF-8" http://localhost:8080/a/projects/myproject/description
=== Authentication
To test APIs that require authentication, the username and password must be specified on
the command line:
curl --user username:password http://localhost:8080/a/path/to/api/
This makes it easy to switch users for testing of permissions.
It is also possible to test with a username and password from the `.netrc`
file (on Windows, `_netrc`):
curl -n http://localhost:8080/a/path/to/api/
In both cases, the password should be the user's link:user-upload.html#http[HTTP password].
=== Verifying Header Content
To verify the headers returned from a REST API call, use `curl` in verbose mode:
curl -v -n -X DELETE http://localhost:8080/a/path/to/api/
The headers on both the request and the response will be printed.
