Yuxuan 'fishy' Wang 61698b14e0 Use the new section title style in Asciidoctor.
We previous use the section title style like:

Section level 1
===============

Section level 2
---------------

Which have a problem in Asciidoctor that the number of "="s or "-"s must match
the number of characters in the header exactly, as a result it's easy to make
mistakes while changing the titles. Asciidoctor provides a better style like:

= Section level 1

== Section level 2

So we switched to this style.

Also fixed a bug in replace_macros.py, which will not cause any problem in the
old style.

= 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/
----
=== Authentication
To test APIs that require authentication, the username and password must be specified on
the command line:
----
curl --digest --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 --digest -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 --digest -X DELETE http://localhost:8080/a/path/to/api/
----
The headers on both the request and the response will be printed.
