[FIXED] PHP Composer behind http proxy

Issue

I use composer on a network where the only way to access the internet is using HTTP or socks proxy. I have http_proxy and https_proxy environment variables. When compose tries to access HTTPS URLs I get this:

 file could not be downloaded: failed to open stream: Cannot connect to HTTPS server through proxy

As far as I know the only way to connect to a https website is using a connect verb. How can I use composer behind this proxy?

Solution

If you're on Linux or Unix (including OS X), you should put this somewhere that will affect your environment:

export HTTP_PROXY_REQUEST_FULLURI=0 # or false
export HTTPS_PROXY_REQUEST_FULLURI=0 #

You can put it in /etc/profile to globally affect all users on the machine, or your own ~/.bashrc or ~/.zshrc, depending on which shell you use.

If you're on Windows, open the Environment Variables control panel, and add either a system or user environment variables with both HTTP_PROXY_REQUEST_FULLURI and HTTPS_PROXY_REQUEST_FULLURI set to 0 or false.

For other people reading this (not you, since you said you have these set up), make sure HTTP_PROXY and HTTPS_PROXY are set to the correct proxy, using the same methods. If you're on Unix/Linux/OS X, setting both upper and lowercase versions of the variable name is the most complete approach, as some things use only the lowercase version, and IIRC some use the upper case. (I'm often using a sort of hybrid environment, Cygwin on Windows, and I know for me it was important to have both, but pure Unix/Linux environments might be able to get away with just lowercase.)

If you still can't get things working after you've done all this, and you're sure you have the correct proxy address set, then look into whether your company is using a Microsoft proxy server. If so, you probably need to install Cntlm as a child proxy to connect between Composer (etc.) and the Microsoft proxy server. Google CNTLM for more information and directions on how to set it up.
