dos set proxy ip: CMD/DOS command line network request proxy setting tutorial

Hands-on guide to set up a netbook proxy IP from the command line.

The development of the old iron must have encountered this situation - some command-line tools are not connected to the Internet, especially the need to go to a specific network environment scenarios. This timeproxy IPIt's a lifesaver, today we'll talk about how to set up a proxy directly in the CMD/DOS window.

Why do I need an agent at the command line?

For example, you write a crawler script in python, it runs happily in the IDE, but when you execute it on the command line, it reports a network error. This is because many development tools do not inherit system proxy settings, which must be configured separately at the command line. There are also some server environments that don't have a graphical interface and must be operated from the command line.

Proxy settings in three steps

// Set the temporary proxy (reboot disabled)
set http_proxy=http://用户名:密码@proxyIP:port
set https_proxy=http://用户名:密码@proxyIP:port

// View the current proxy configuration
netsh winhttp show proxy

// Clear the proxy settings
netsh winhttp reset proxy

Note that there is a pitfall here: if the agent requires authentication, remember to put thespecial symbol转义。比如密码里有@符号，就得改成%40。举个真实案例，之前有哥们密码是P@ssw0rd，设代理时就该写成P%40ssw0rd。

curl -x http://代理IP:端口 http://ipipgo.com/ip

If the returned IP is not the same as your local IP, the proxy is working. If you get an error, it's probablyProxy IP failureorThe port is wrong., it's time to switch available resources.
