How to use the gerrit REST API

[Olivier Paule]

Hi all,

I hope I'm in the good group to ask my question.

Usually, I use the command "ssh www.myserver.com gerrit query --commit-message --current-patch-set 123456" to retrieve a JSON with data I need.

I would like to retrieve the same data using the REST API of gerrit (on the url https://www.myserver.com/123456) but I'm stuck.

Can someone help me please? :-)

Thanks

To get the same data as in your ssh command you will want to do
something like:

curl -n --digest
"http://www.myserver.com/a/changes/CHANGEID/detail/?o=CURRENT_REVISION&o=CURRENT_COMMIT"

- The HTTP username and password (from the "HTTP password" page on your
user settings) should be in the ~/.netrc file.

- Replace "CHANGEID" with the Change Id in the format
"project~branch~revision". The project name and branch name should be
url encoded.

For further details check the documentation [1].

Thanks for your response.

I forgot something. This is for a php page. And I am under Windows (using wampserver). I cannot find where is the  ~/.netrc for my Apache user.

I tried with curl_setopt($curl, CURLOPT_USERPWD, "$username:$password"); but that does not work.

What does "doesn't work" mean?

Are you using a service user, or a regular user? If it's a regular user,
are you using the extra HTTP password to be set through the settings, or
your main password?

Cheers,
Jan

This link should help [1].  Scroll down a bit and it explains the environment vars you need to set.  Also note that the name of the file is _netrc on Windows, not .netrc as it is on Ubuntu et al.

Please be more specific than "does not work".  Does it fail to authenticate?  Any error message?

It's a long time since I used php so I can't help with that.  All I can suggest is to make sure the request is using digest authentication, or, try it without authentication by removing /a/ from the url.

It means "Unauthorized access".

Wampserver uses a service user "nt authority\system". Creating a ssh key for this user would be great. But for now, I don't know how.

I tried with both my password and the http password.

I get: "Unauthorized access".

I'll see how to use digest authentication with curl_setopt.

[Olivier PAULE]

Here is what I did:

$curl = curl_init();

curl_setopt($curl, CURLOPT_USERPWD, "$username:$password");

curl_setopt($curl, CURLOPT_URL, $url);

curl_setopt($curl, CURLOPT_HTTPAUTH, CURLAUTH_DIGEST);

curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);

curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1);

curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 0);

curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 0);

$issue_list = (curl_exec($curl));

var_dump($issue_list);

And I get:

tring '<html>
<head>
<meta http-equiv="Content-Type" content="text/html;charset=ISO-8859-1"/>
<title>Error 401 Unauthorized</title>
</head>
