curlrc set proxy: configuration file permanent

This is probably the most hassle-free solution for setting up curl proxies

Engaged in web development know, with curl test interface always with -proxy parameters, not to mention the trouble is also easy to forget. In fact, there is a hidden trick: in the user directory to create a.curlrcfile to write the proxy configuration in, once and for all. Here's how to play around with this configuration file, using ipipgo's proxy service as a chestnut.

 Enter this line in the terminal (don't miss the dot before it)
touch ~/.curlrc

 The file looks like this:
proxy = http://username:password@proxy.ipipgo.io:8080

Hands on environment matching

Let's get a few key points out of the way:

1. Documents must be placeduser root directory(Windows at C:Users your username, Mac/Linux at ~)

2. proxy address should be replaced with the address given by the ipipgo package you bought, do not directly copy my example

3. 密码里有特殊符号的话记得用百分号转义，比如@要写成%40

 Let's take a real scenario:
 Let's say you get the socks5 proxy in the ipipgo backend
proxy = socks5://vip001:mYp@ssw0rd@gateway.ipipgo.net:1080

Test the proxy to see if it's working.

Don't wait to use it after configuration, run a diagnostic command first:

curl -v http://whatismyip.ipipgo.com

Focus on the returnedX-Forwarded-ForHeader, if it shows the server IP of ipipgo, it means the configuration is successful. If you get a 407 error, it's probably an account password error.

QA Time: A Guide to Ducking the Pit

Q: How come it doesn't work after I've matched the file?
A: First check the file permissions withls -la ~/.curlrcSee if it's -rw-r-r-, if not use thechmod 644change authority

Q: Do I need to distinguish between http and https proxies?
A: Use ipipgo's proxy service does not need, their gateway will automatically recognize the protocol, configure a proxy parameter on the line!

Q: What should I do if I have an exception address on my company's intranet?
A: In .curlrc addnoproxy = ".internal.company,192.168..."Support for wildcards

Why do you recommend ipipgo?

There are three main advantages of their home agent pool:

Particularly suitable for scenarios that require a long-term stable agent, such as crawler projects or automated testing. Used to know, than those who need to frequently change the agent of the wild way to save a lot.

Advanced Tips: Multi-Environment Switching

Play around a bit in .curlrc for development/production environment switching:

 Comment out the default proxy
 proxy = http://default.ipipgo.net:80

 For development environments
proxy-dev = http://dev.ipipgo.net:8080

To use it, add--config-attr proxy=proxy-dev, this cold parameter 90% people do not know.

Finally, a nagging word: with the proxy service remember to comply with local laws and regulations, ipipgo IP are regular server room resources, do not take to do illegal things. Encountered technical problems directly to their customer service, response speed than the free agent much more stable.
