如何使用代理配置composer'

Question

First of all I apologize for my English and thank you in advance for any response. I was reading several solutions about the configuration of composer behind a proxy but the truth is that I still have problems. Already create the environment variables

HTTP_PROXY_REQUEST_FULLURI = false
HTTPS_PROXY_REQUEST_FULLURI = false
HTTP_PROXY = my_http_proxy: proxy_port
HTTPS_PROXY = my_https_proxy: proxy_port

But I get the following problem when I use composer: The "https://packagist.org/packages.json" file could not be downloaded: failed to open stream: Cannot connect to HTTPS server through proxy https://packagist.org could not be fully loaded, package information was loaded from the local cache and may be out of date

[Composer\Downloader\TransportException]
The 'http://packagist.org/p/provider-    2013%24c23e27d4ef97dede5bbe3fe1d348566
bd1a463ccbe767186c51beab5436c9bad.json' URL could not be accessed:     HTTP/1.1
400 Bad Request 

Again thank you for any help and time you can give me

Answer 1

Maybe your SO need define variables in lower case, or maybe you need define user and password for your proxy.

Another thing in my case was I didn't set http_proxy variable with "http://" part like below:

http_proxy = http://username:password@ip:port
and
https_proxy = http://username:password@ip:port
