如何配置cURL使其默认始终使用SOCKS代理？

Got it, let's get this sorted so you don't have to type that tedious --socks5 flag every time you run cURL! There are two solid ways to set a default SOCKS proxy for cURL—one that's persistent (via a config file) and another that's flexible (via environment variables). Here's how each works:

This is the best option for permanent defaults, since it lives in a file and applies to all your cURL requests automatically.

• Linux/macOS: Create or edit the file ~/.curlrc (it might not exist yet, so just make it with touch ~/.curlrc if needed).
• Windows: Create or edit %APPDATA%\curl\.curlrc (or C:\Users\<YourUsername>\.curlrc if that path doesn't exist).
• Add this line to the file, replacing <proxy name> and <proxy port> with your actual proxy details:

  socks5 = socks5://<proxy name>:<proxy port>
  

  Example: If your proxy is running on localhost port 1080, it would be socks5 = socks5://localhost:1080.
• Save the file, and that's it! Now any curl <url> command you run will automatically use the SOCKS proxy.

Pro tip: If you ever need to bypass the proxy temporarily, just add the --noproxy "*" flag:

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

This is great if you want to set the proxy only for the current terminal session, or if you prefer not to edit config files.

Linux/macOS (Bash/Zsh) #

• For a temporary session: Run this in your terminal:

  export ALL_PROXY=socks5://<proxy name>:<proxy port>
  

• For permanent global setup: Add the above line to your ~/.bashrc, ~/.zshrc, or shell profile file, then run source ~/.bashrc (or the corresponding file) to apply changes immediately.

Windows #

• Command Prompt (CMD):
  • Temporary: Run set ALL_PROXY=socks5://<proxy name>:<proxy port>
  • Permanent: Go to This PC → Properties → Advanced System Settings → Environment Variables, add a new user variable named ALL_PROXY with the proxy address as its value.
• PowerShell:
  • Temporary: Run $env:ALL_PROXY = "socks5://<proxy name>:<proxy port>"
  • Permanent: Edit your PowerShell profile with notepad $PROFILE, add the line above, save, and restart PowerShell.

Bonus: Proxy with Authentication #

If your SOCKS proxy requires a username and password, use this format for either the config file or environment variable:

socks5://<username>:<password>@<proxy name>:<proxy port>
