Curl call REST API: cURL proxy REST call code

Teach you how to use cURL to hang a proxy to call interface

Brothers engaged in interface calls should have encountered this situation: local debugging good code, on the line on the crazy error. If you can hang a proxy IP at this time, many problems can be solved. Let's take the most common curl command to start, say how to give it a "cloak".

What's the point of a proxy IP anyway?

Simply put, it gives your web requestPut on a vest.。比如你网站访问太频繁被限制，换个IP就能继续操作；或者需要测试不同地区的访问效果，用代理IP比肉身代理靠谱多了。这里推荐用ipipgo的住宅代理，他们家的IP都是真人上网用的真实地址，不容易被识别。

 Example of minimal proxy setup
curl -x http://用户名:密码@proxy address:port https://目标网址

The actual code should be looked at carefully

Here's the point! Remember the difference between these two parameters:

 Normal proxy mode (recommended)
curl --proxy http://ipipgo_user:password123@gateway.ipipgo.com:9020 -X GET http://api.example.com

 Write this when you need to go HTTPS
curl --proxy https://gateway.ipipgo.com:9021 --proxy-user ipipgo_user:password123 -k https://secure-api.com

Watch the port number change, ipipgo's HTTP proxy uses port 9020, HTTPS dedicated channel is 9021. if you get it wrong, you will not be able to connect to it, I've stepped over this pit for you.

Great job on the environment variables!

Temporary settings can be operated with this soi:

export http_proxy=http://ipipgo_user:密码@proxy:9020
export https_proxy=http://ipipgo_user:密码@proxy:9021
curl -I https://whatismyip.com This will check the current export IPs

Common Rollover Scene QA

Q: The proxy is set but it doesn't work?
A: First check three elements: protocol header (http/https), port number, and account password. It is recommended to usecurl -vSee the detailed log

Q: HTTPS requests always have certificate errors?
A: Try adding-kParameters temporarily skip the verification, long-term use is recommended in the ipipgo background to download their CA certificate

Q: How to change IP automatically?
A: Use ipipgo's Dynamic Residential Package, their API extraction interface will return new IPs, remember to add a random delay in your code!

Say something from the heart.

When I first started using proxy IP, I was also confused by the various protocols and ports. Later, I realized that the core of the three points:Choose the right service provider, memorize the connection parameters, and make good use of debugging tools.. Now use ipipgo's API to extract IP, with shell scripts to automatically switch, the efficiency is directly doubled. If you don't understand anything, just go to their official website and look for code examples, it's much better than blindly doing it yourself.
