Can't specify http.extraheader

[ermshiperete]

I'm trying to implement the equivalent of

git -c http.extraheader="Authorization: Basic $TOKEN" push $REMOTE $BRANCH

However, the following doesn't work:

git.raw([
  '-c',
  `http.extraheader="Authorization: Basic ${token}"`,
  'push',
  remote,
  branch,
]);

I get a The requested URL returned error: 400 from github whereas calling the above command on the command line works. Is this a bug or am I doing something wrong?

I have the same problem. Did you manage to find a solution ?

In my testing, the commands in your example are passed to the ChildProcess used by simple-git. Are you able to switch to adding configuration with addConfig instead?

const gitP = require('simple-git/promise');
const git = gitP('./').addConfig('http.extraheader', `Authorization: Basic ${token}`);

const result = await git.push(remote, branch);

For me, the problem is with the clone command so I can't use the addConfig given the fact that I don't have local git configuration yet.

You could try logging all output by adding the GIT_TRACE environment variable

const GIT_TRACE = true;
const gitP = require('simple-git/promise');
const git = gitP('./').env({ ...process.env, GIT_TRACE });

const result = await git.raw(['-c', `http.extraheader="Authorization: Basic ${token}"`, remote, branch]);

The standard git binary uses curl for any http request, adding GIT_TRACE will add curl's verbose output to stdout which should help find where the header is being lost.

So I ran the clone command with simple-git and in command line. And here is the difference in the trace logs:
With Simple Git

exec-cmd.c:238          trace: resolved executable dir: ***/git-core
fatal: unable to access '${my_url}: The requested URL returned error: 400

With Command Line

exec-cmd.c:238          trace: resolved executable dir: ***/git-core
12:17:56.155715 run-command.c:663       trace: run_command: git fetch-pack --stateless-rpc --stdin --lock-pack --thin --check-self-contained-and-connected --cloning ${my_url}

[steveukx]

The format of the http.extraHeader setting requires that there are no quotes in the value, this passes the header through to the remote repo:

const header = `http.extraHeader=X-Foo: Bar`;
const result = await git.raw(['-c', header 'clone', repo]);

Whereas this fails:

const header = `http.extraHeader="X-Foo: Bar"`;
const result = await git.raw(['-c', header 'clone', repo]);

Please can you check that your header argument is formatted without the quotes...

[NightFox7]

You are correct. Thank you ! It works now.

[steveukx]

No problem, I'll add to the readme shortly.

@ermshiperete this info should resolve your query too - please ensure you are passing a correctly formatted string as the -c value (ie: http.extraheader=Authorization: Basic ${token} without the ")
