Basic usage tutorial

[zhmq0124v]

Dear gurus,

I am currently trying to get project list and branches of a project, but my code failed at the beginning. The exception is
com.fasterxml.jackson.core.JsonParseException: Unexpected character ('<' (code 60)): expected a valid value (number, String, array, object, 'true', 'false' or 'null')
at [Source: <title>Request Rejected</title>The requested URL was rejected. Please consult with your administrator.

Here is my code:
final String URL = "https://example.com";
final String token = "myToken";
api = GitlabAPI.connect(URL, token);
System.out.println(api.getProjects().size());

Could you please take a look?
A basic tutorial in readme would be better, I tried gitlab python API it works but I prefer to use Java.
Thanks.

It works for me.

GitlabAPI api = GitlabAPI.connect("https://gitlab.com", private_token);
System.out.println(api.getProjects().size());

I made sure to grab the token from https://gitlab.com/profile/account or whatever it is for your server. If your token is right try visiting the url in your browser to make sure you get JSON (it sounds like the response is HTML).

Try this url, with the right hostname and token:
https://gitlab.com/api/v3/projects?private_token=<private_token>

Thanks, your url works perfectly.
I also tried https://gitlab.com, it worked too.
But when access my own gitlab server, I still get the following exception. Is it because my gitlab server version too low or any other settings?(it works with python API)...

I would think it would have to be either a setting on your GitLab server or possibly the version? I'm not sure, I've never ran into those issues. I feel like if the URL works in your browser then it should work in the Java code.

What version of GitLab do you have?

[zhmq0124v]

I am using GITLAB 6.
Not sure why URL works while API does not.
My GITLab server is https://git-lenovo.hybris.hec.ondemand.com/
Could (invalid) SSL certificate be the root cause?

[rockwotj]

The invalid SSL cert should not be the issue:

https://github.com/timols/java-gitlab-api/blob/master/src/main/java/org/gitlab/api/http/GitlabHTTPRequestor.java#L367

I think @timols will have to help you here, I don't have any insight for you. Sorry!

[zhmq0124v]

You can create a new user in https://git-lenovo.hybris.hec.ondemand.com/ and test the API.
@rockwotj @timols I had tried days, the site itself might have issues but I could not figure it out.

[rockwotj]

This is the data that I'm getting back from the HTTP request and this is the URL it's requesting: https://git-lenovo.hybris.hec.ondemand.com/api/v3/projects. But again, it works from the browser.

Have you checked the GitLab logs?

[zhmq0124v]

Sorry, I have no access to GitLab logs.
I am really confused, URL in browser works, Python API also works.
Did I missing something in my code or settings in GitLab?

[rockwotj]

I can't think of a settings issue. I'd have to look at the difference between the Python API and the Java client to see the difference

[zhmq0124v]

@rockwotj @timols the root cause has been found: remote Gitlab server requires valid browser(user-agent) information.
We need to check how Python overcomes this restriction.

[rockwotj]

You should be able to set the User-Agent header here.

Thanks, issue has been resolved.
