【Turn】CURL command uses proxies and proxies are introduced

Sometimes for privacy reasons, we want to hide our IP so that the http server cannot record that we have accessed it, and then we can use a proxy server.

Proxy Server is a service application that works between the browser and the http server, and all http requests that pass through the proxy server will be forwarded to the corresponding http server.

Of course, in addition to HTTP proxy, https, ftp, RTSP, pop3 and other protocols can also be accessed by proxy, but this article introduces proxies that support http and https protocol access.

1. Proxy server classification:

There are two main types of proxies that are commonly used and support the HTTP(S) protocol: HTTP proxies and SOCKS proxies, see the following table:

Category	Subcategory	Subcategories	description
http proxy	http proxy https proxy	Transparent proxy	The http server knows that the browser uses a proxy and can obtain the original IP address of the browser.
		Anonymous agents	The http server knows that the browser uses a proxy, but cannot obtain the original IP address of the browser side.
		High anonymity proxies	The http server does not know that the browser side uses a proxy and cannot obtain the original IP address of the browser side.
SOCKS Agent	SOCKS4	Known as the Almighty Generation Reason, support http and other agreements	Only TCP applications are supported.
	SOCKS4A		Support TCP applications; Server-side domain name resolution is supported.
	SOCKS5		Support TCP and UDP applications; Server-side domain name resolution is supported. Support multiple authentications; IPV6 support;

2. Linux curl command proxy setting parameters:

The Linux curl command can use the following parameters to set the HTTP(S) proxy and SOCKS proxy, and their usernames, passwords, and authentication methods have been set:

parameter	usage
-x host:port -x [protocol://[user:pwd@]host[:port] --proxy [protocol://[user:pwd@]host[:port]	Access using HTTP proxy; If no port is specified, port 8080 is used by default. protocol defaults to http_proxy, other possible values include: http_proxy、HTTPS_PROXY、socks4、socks4a、socks5； As: --proxy 8.8.8.8:8080； -x "http_proxy://aiezu:123@aiezu.com:80"
--socks4 <host[:port]> --socks4a <host[:port]> --socks5 <host[:port]>	Use SOCKS4 agents; Use SOCKS4A agents; Use SOCKS5 agents; This parameter overrides the "-x" parameter;
--proxy-anyauth --proxy-basic --proxy-diges --proxy-negotiate --proxy-ntlm	Agent authentication methods, reference: --anyauth --basic --diges --negotiate --ntlm
-U <user:password> --proxy-user <user:password>	Set the proxy's username and password;

3. Linux curl command setting proxy example:

1. Linux curl command to set HTTP proxy:

# Specify the http proxy IP and port
curl -x 113.185.19.192:80http://aiezu.com/test.php
curl --proxy 113.185.19.192:80http://aiezu.com/test.php

#指定为http代理
curl -x http_proxy://113.185.19.192:80http://aiezu.com/test.php

#指定为https代理
curl -x HTTPS_PROXY://113.185.19.192:80http://aiezu.com/test.php

#指定代理用户名和密码, basic authentication method
curl -x aiezu:123456@113.185.19.192:80http://aiezu.com/test.php
curl -x 113.185.19.192:80 -U aiezu:123456http://aiezu.com/test.php
curl -x 113.185.19.192:80 --proxy-user aiezu:123456http://aiezu.com/test.php

#指定代理用户名和密码. NTLM authentication method
curl -x 113.185.19.192:80 -U aiezu:123456 --proxy-ntlmhttp://aiezu.com/test.php

#指定代理协议, username and password, basic authentication method
curl -x http_proxy://aiezu:123456@113.185.19.192:80http://aiezu.com/test.php

2. Linux curl command to set the socks agent:

#使用socks4代理, no authentication method is required
curl --socks4 122.192.32.76:7280http://aiezu.com/test.php
curl -x socks4://122.192.32.76:7280http://aiezu.com/test.php

#使用socks4a代理, no authentication method is required
curl --socks4a 122.192.32.76:7280http://aiezu.com/test.php
curl -x socks4a://122.192.32.76:7280http://aiezu.com/test.php

#使用socks5代理, basic authentication method
curl --socks5 122.192.32.76:7280 -U aiezu:123456http://aiezu.com/test.php
curl -x socks5://aiezu:123456@122.192.32.76:7280http://aiezu.com/test.php

#使用socks5代理, basic authentication method, NTLM authentication method
curl -x socks5://aiezu:123456@122.192.32.76:7280 --proxy-ntlmhttp://aiezu.com/test.php
