Corporate Proxy Azure Devops with Git

问题:

I've created a Project and Repo inside of Azure Dev-Ops. We are sitting behind a corporate proxy and would like to clone from this project.

I have set the environment variables http_proxy,https_proxy, HTTP_PROXY,HTTPS_PROXY, git config --global https.proxy, git config --global http.proxy to the matching http or https version below http://domain\username:password@ProxAddr:Proxy or https://domain\username:password@ProxAddr:Proxy

When I run git clone https://username:[e-mail]/username/ProjectName/_git/RepoName, I receive the error below.

Cloning into 'ProjectName'...

fatal: unable to access 'https://username:[e-mail]/username/DevOpsProject/_git/DevOpsRepo/': gnutls_handshake() failed: Error in the push function.

The error appears to be this?

< Proxy-Authenticate: NEGOTIATE
* gss_init_sec_context() failed: : SPNEGO cannot find mechanisms to negotiate

Do I need to explicitly state something?

回答1:

It looks like your proxy may be misconfigured, and is offering authentication mechanisms it can't support (in this case, Negotiate). You can work around this by setting the http.proxyAuthMethod option to something suitable. Based on the output, you'll probably want to use ntlm or basic.

In addition, you can set this on a per-url or pattern basis by using something like git config http.https://*.azure.com/.proxyAuthMethod ntlm for all HTTPS URLs with hostnames matching *.azure.com.

Updating to a newer version of git resolves this.
