Proxy IP Implementation of cURL HTTPS POST: cURL Proxy IP HTTPS Submit

Hands-on teaching you to play with proxy IP cURL requests

Engaged in the development of small partners should have encountered this situation: local debugging interface is always restricted, or need to batch test the effect of access to different regions. This time we have to ask the proxy IP this magic weapon! Let's useipipgoProxy service, hand in hand to teach you how to hang proxy in the cURL to send HTTPS POST request.

What exactly is a proxy IP?

Simply put, it helps youChange network outlets.The transit station. For example, your local IP is Beijing, through the proxy IP can be disguised as Shanghai, Guangzhou and even foreign export address. Here to remind, choose the proxy service provider to open eyes, like theipipgothis kind of provisionHigh Stash AgentsIt's only reliable and won't give away the real IP.

Why do I have to use a proxy to send a request?

Let's take a real-life scenario: when doing data collection the target website hasIP access frequency limitationIf you don't use a proxy, you'll be blocked in minutes. Another example is the testterritorial function(like weather interfaces in different regions), you can't really carry a computer around, can you? This is where hooking up a proxy can simulate multi-location access.

Real-world code walk!

First, install the latest version of cURL (version 7.60 or above is recommended), then prepare aipipgoThe address of the proxy. Their home proxy format looks like this:http://用户名:密码@gateway.ipipgo.com:端口

curl -x "http://user123:pass456@gateway.ipipgo.com:8899"
-H "Content-Type: application/json"
-d '{"phone": "13800138000", "code": "1234"}'
-X POST https://api.example.com/login

Code Explanation:

-x parameterSpecify a proxy server
-HSet the request header (in json format here)
-dFollowed by POST data
Note that the proxy address in theUser name and passwordIf you were to replace yourself in theipipgoCredentials obtained in the backend

Guide to avoiding pitfalls (actual blood and tears experience)

1. timeout setting: Recommendation to add--connect-timeout 30parameter to prevent the proxy server from responding slowly and getting stuck
2. Certification issues: SSL errors can be added to-kParameter skip validation (use with caution in production environments)
3. IP Switching::ipipgoThe API supports dynamic acquisition of proxy pools, so remember to change to a different proxy each time when doing batch operations.

These are the questions you always ask.

Q: What should I do if the proxy settings don't take effect?
A: First withcurl -vLook at the request details and check if the proxy address is formatted correctly, especially the special symbols to be URL-encoded

Q: What is the difference between an HTTPS proxy and an HTTP proxy?
A:ipipgoThe gateway automatically adapts to the protocol, so you can use the same address without distinguishing between

Q: How to automatically switch between agents in different regions?
A: CallipipgoThe -x parameter value is dynamically replaced in the code to get the proxy node for the specified city.

Agent service provider selection doorway

I've used five or six proxy service providers, and in the end, the one that renews for the long term is stillipipgo. Mainly their homeConnection StabilityTop indeed, it's rare to encounter disconnections in the middle when doing automation scripts. New users also get a free1G flow, enough for testing.

The last nagging sentence: proxy IP used well, work efficiency doubled early! Encounter specific problems can be directly pickipipgoThe official document, written in a very grounded, much stronger than those yanking jargon. Code millions of lines, the first line of stability, the proxy is not standardized, debugging two lines of tears!
