Answer 1

You need to write this in the command prompt:

set HTTP_PROXY=http://your_proxy:your_port

Answer 2

For http/https proxy with or without authentication:

Run one of the following commands in cmd.exe

set http_proxy=http://your_proxy:your_port
set http_proxy=http://username:password@your_proxy:your_port
set https_proxy=https://your_proxy:your_port
set https_proxy=https://username:password@your_proxy:your_port

Answer 3

You can try export http_proxy=http://your_proxy:your_port

Answer 4

In Addition to @Yifei answer. If you have special character like @, &, $

You have to go with percent-encode | encode the special characters. E.g. instead of this:

http://foo:B@r@http-gateway.domain.org:80

you write this:

http://foo:B%40r@http-gateway.domain.org:80

So @ gets replaced with %40.

Answer 5

When setting http_proxy and https_proxy, you are also probably going to need no_proxy for URLs on the same side of the proxy. https://msdn.microsoft.com/en-us/library/hh272656(v=vs.120).aspx

Answer 6

You need to add http_proxy and https_proxy environment variables as described here.
