composer installation from behind proxy server - php

Question

I'm trying to run composer update on windows 10 behind a proxy server, it gives me an error.
and I set http proxy using below command
SET HTTP_PROXY="http://192.168.1.6:808"
SET HTTPS_PROXY="http://192.168.1.6:808"
this also return same error.

Answer 1

Here are the key points to make Composer work behind a proxy (works on Windows, didn't try on Linux):
1) URL encode your password (for special characters)
You can do that easily with the PHP command line, for example:
Input:
php -r "echo urlencode('P*a/$$/w!0%r$d');"
Output:
P%2Aa%2F%24%24%2Fw%210%25r%24d
Use the generated value to set the HTTP_PROXY and HTTPS_PROXY env variables.
2) Remove the quotes around the HTTP_PROXY and HTTPS_PROXY env variables
From:
SET HTTP_PROXY="http://username:password#hostname:port"
SET HTTPS_PROXY="http://username:password#hostname:port"
To:
SET HTTP_PROXY=http://username:password#hostname:port
SET HTTPS_PROXY=http://username:password#hostname:port
Composer WON'T WORK with quotes, it uses the PHP core function "parse_url" to parse the variable:
With quotes:
php -r "print_r(parse_url('\"http://username:password#proxy:8080\"'));"
Array
(
[path] => "http://username:password#proxy:8080"
)
Without quotes:
php -r "print_r(parse_url('http://username:password#proxy:8080'));"
Array
(
[scheme] => http
[host] => proxy
[port] => 8080
[user] => username
[pass] => password
)
3) Make sure the certificate authority file or path is correctly set for HTTPS connections
Composer will use the first readable file or path in the following order:
Env variables:
SSL_CERT_FILE
SSL_CERT_DIR
php.ini:
openssl.cafile
openssl.capath
Files:
/etc/pki/tls/certs/ca-bundle.crt
/etc/ssl/certs/ca-certificates.crt
/etc/ssl/ca-bundle.pem
/usr/local/share/certs/ca-root-nss.crt
/usr/ssl/certs/ca-bundle.crt
/opt/local/share/curl/curl-ca-bundle.crt
/usr/local/share/curl/curl-ca-bundle.crt
/usr/share/ssl/certs/ca-bundle.crt
/etc/ssl/cert.pem
/usr/local/etc/ssl/cert.pem
/usr/local/etc/openssl/cert.pem
Non-empty folder:
/etc/pki/tls/certs/
/etc/ssl/certs/
/etc/ssl/
/usr/local/share/certs/
/usr/ssl/certs/
/opt/local/share/curl/
/usr/local/share/curl/
/usr/share/ssl/certs/
/etc/ssl/
/usr/local/etc/ssl/
/usr/local/etc/openssl/
If none of the above is valid, Composer will use its embedded file:
composer.phar /vendor/composer/ca-bundle/res/cacert.pem
4) If you experience the "certificate verify failed" error
[Composer\Downloader\TransportException]
The "https://packagist.org/packages.json" file could not be downloaded: SSL operation failed with code 1. OpenSSL Error messages:
error:14090086:SSL routines:ssl3_get_server_certificate:certificate verify failed
failed to open stream: Cannot connect to HTTPS server through proxy
This means that the used CA file or path does not contains the required certificates.
You may then:
extract the default file from composer.phar:
php -r "(new Phar('composer.phar'))->extractTo('/tmp/cacert/', 'vendor/composer/ca-bundle/res/cacert.pem');"
then add the required certificates (e.g. your company proxy certificates) to the end of the file
and force this file in php.ini
[openssl]
; The location of a Certificate Authority (CA) file on the local filesystem
; to use when verifying the identity of SSL/TLS peers. Most users should
; not specify a value for this directive as PHP will attempt to use the
; OS-managed cert stores in its absence. If specified, this value may still
; be overridden on a per-stream basis via the "cafile" SSL stream context
; option.
openssl.cafile=/tmp/cacert/vendor/composer/ca-bundle/res/cacert.pem

Answer 2

Maybe it needs authentication too? Try this if so:
SET HTTP_PROXY="http://username:password#hostname:port"
SET HTTPS_PROXY="http://username:password#hostname:port"

Answer 3

encode your password then use
SET HTTP_PROXY="http://username:encodedPassword#hostname:port"
SET HTTPS_PROXY="http://username:encodedPassword#hostname:port"

Answer 4

The best way if it fails to work is to enter this command
SET HTTP_PROXY=0
SET HTTPS_PROXY=0
This will empty the proxy then you can now use composer.install
