Cannot install laravel/socialite using composer behind proxy - php

Question

I'm using win7x64.
I can install laravel using composer when I'm not behind proxy, but when I'm behind proxy I cannot install anything using composer.
I tried install laravel/socialite I receive error:

this solution
but it still not working
Here are the composer diag stat:
Checking composer.json: OK
Checking platform settings: OK
Checking git settings: OK
Checking http connectivity to packagist: FAIL

" file could not be downloaded: failed to open stream: HTTP request failed!
Checking https connectivity to packagist: OK
Checking HTTP proxy: OK
Checking HTTP proxy support for request_fulluri: FAIL
Unable to assess the situation, maybe packagist.org is down (The "http://packagi
st.org/packages.json" file could not be downloaded: failed to open stream: HTTP
request failed! )
Checking HTTPS proxy support for request_fulluri: OK
Checking github.com rate limit: OK
Checking disk free space: OK
Checking composer version: OK
Is there any setup I missed?

Answer 1

I add this to composer.json
"repositories": [
{
"packagist": false
},
{
"type": "composer",
"url": "https://packagist.org/"
}
],
