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.For example, if your website access is restricted too often, you can continue to operate with a different IP. For example, if your website access is restricted too often, you can continue to operate with a different IP; or if you need to test the effect of access to different areas, using a proxy IP is much more reliable than fleshing over the wall. Here we recommend the use of ipipgo residential proxy, their IP are real people online with real addresses, not easy to be recognized.

 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!

How to choose a ipipgo package

Their TK line is particularly suitable for friends doing cross-border e-commerce, measured latency is lower than the ordinary line 40% or so. New users remember to take the first trial quota, customer service support 24 hours online, encounter technical problems at any time to ask.

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.
