Curl Specify Proxy: Curl Setting Proxy Tutorial

Teach you how to use Curl to hang a proxy!

Engaged in network development know, Curl this tool is as practical as a Swiss Army knife. But some scenarios directly bare access easy to fall, this time the proxy IP is your Golden Bell. Today we do not talk about false, directly on the dry goods to teach you how to use proxy IP to protect Curl request.

Command Line Parameters Most Straight Balls

If you want to use a proxy temporarily, it's easiest to add parameters directly to the command. Remember this universal formula:

curl -x http://用户名:密码@proxy address:port Destination URL

To give a real-life chestnut, suppose one uses theipipgos dynamic residential agent, their address is usually gateway.ipipgo.cn:9021, and the account password can be seen in the console:

curl -x http://user123:pass456@gateway.ipipgo.cn:9021 https://example.com/api

Delineate the focus:parameter in the-xIt can also be written as-proxyThe two are brothers. If the proxy server requires authentication, remember to fill in the account password correctly, otherwise it will return a 407 error.

Great job on the config file.

If you have to hang a proxy every day, it's too much trouble to enter commands every time. Create a new.curlrcfile (Windows in C:Users username), add this line of configuration:

proxy = http://user123:pass456@gateway.ipipgo.cn:9021

When you do this, all curl requests will automatically go to the proxy. If you want to turn it off temporarily, add a-noproxyparameter will be released:

curl --noproxy "" https://example.com

environment variable laziness

Linux/Mac users can set up temporary proxies with export, suitable for use in scripts:

export http_proxy=http://user123:pass456@gateway.ipipgo.cn:9021
export https_proxy=$http_proxy
curl https://example.com

Watch out for potholes:This setting takes effect for all network requests, remember to unset to cancel when you run out:

unset http_proxy https_proxy

Practical QA Triple Strike

Q: Proxy setting is successful but the request fails?
A：First check if the proxy address and port are correct, and then test whether the proxy itself is available. It is recommended to useipipgos online testing tool, their proxies come with a 99.9% availability guarantee.

Q: What if I need to switch between different agents frequently?
A: You can set up shortcut commands with alias, or use theipipgoThe API provided dynamically fetches proxies and they support filtering IPs by region/carrier.

Q: How to solve the problem of slow agent speed?
A: Prioritize geographically proximate nodes thatipipgoThe smart routing feature will automatically match the fastest route. If going http proxy is slow, try their version of socks5 protocol.

Choosing an agent depends on the doorway

The agent service providers on the market are a mixed bag, and here we must be amenable to the followingipipgoThe three best things about it:

• Native Residential IP in 200+ cities nationwide
• Exclusive support for TCP/UDP dual protocol
• Automatic IP rotation without fear of banning

Especially friends doing data collection, with their agents with Curl scripts, the success rate can be directly pulled full. New user registration also send 1G flow trial, pro-test effective not fooled.

最后提醒下，代理参数里的特殊字符记得用百分号转义。比如密码里有@符号就要写成%40，这个坑不少人栽过跟头。有啥不明白的，直接去ipipgoThe official website is much quicker to find 24-hour online technical customer service than to check the documentation.
