The curl Command with Request Header: Advanced Request Configuration

What the heck is a request header? Let's get the basics out of the way

We usually use curl to send a request like sending a courier, the request header is attached to the parcelLogistics LabelingFor example, tell them: "I'm making this request from an Android phone" or "I support compression". For example, tell the other side: "I am from the Android phone request" or "I support compressed format". Some websites specifically block requests without a request header, this time we need to manually forge the courier receipt number.

For example, a website only accepts visits from WeChat's built-in browser. We use ordinary curl direct access will be pinched neck, this time with such a request header can be fooled:

curl -H "User-Agent: MicroMessenger/8.0"
-H "Referer: https://servicewechat.com/"

Proxy IPs and request headers are a good pair of friends.

Using a proxy IP alone is like going out with a mask on, but you'll still be recognized if you're wearing your original clothes. This is where the request header is yourprops for dress-up. When using ipipgo's proxy service, it is recommended to configure all three key headers at the same time:

Hands-on Advanced Configuration

Here's a real-world example of using ipipgo's residential proxy + custom request headers for data collection:

curl -x http://user:password@proxy.ipipgo.com:8000
-H "User-Agent: Mozilla/5.0 (iPhone; CPU iPhone OS 14_7_1 like Mac OS X)"
-H "Accept-Encoding: gzip, deflate" -H "Cookie: sessionid=abc123"
-H "Cookie: sessionid=abc123"
--connect-timeout 15
--max-time 30

• -connect-timeoutControl the connection wait time and give up if it exceeds
• User-AgentDisguised as an Apple phone here, adjusted to the target

First Aid Guidelines for Common Rollover Scenes
