如何在Godot 3中配置网络代理及代理授权？

Hey there! I’ve dealt with proxy setups in Godot 3 before, so let me walk you through the steps to get it working with authentication smoothly.

1. Using the Editor's Graphical Interface #

Godot 3 has built-in proxy settings that are straightforward once you know where to look:

• Open Godot 3, then go to Editor > Editor Settings (or use the shortcut Ctrl+, on Windows/Linux, Cmd+, on macOS).
• In the left sidebar, navigate to Network > HTTP.
• Fill in the required fields:
  • Proxy Host: Your proxy server’s IP address or domain (e.g., proxy.yourcompany.com).
  • Proxy Port: The port your proxy uses (common values are 8080 or 3128).
  • Proxy User: Your proxy username if authentication is required.
  • Proxy Password: Your proxy password corresponding to the username.
• Click Save Settings at the bottom right, then restart the editor to ensure changes take effect.

2. Manual Configuration via the Config File #

If the GUI isn’t working for you, or you prefer editing files directly, modify the editor config file:

• Locate the Godot 3 configuration folder based on your OS:
  • Windows: %APPDATA%\Godot\editor_settings-3.tres
  • Linux: ~/.config/godot/editor_settings-3.tres
  • macOS: ~/Library/Application Support/Godot/editor_settings-3.tres
• Open the file with a text editor, find the [network/http] section, and add/modify these lines:

  proxy_host = "your_proxy_host"
  proxy_port = your_proxy_port
  proxy_user = "your_proxy_username"
  proxy_password = "your_proxy_password"
  

• Save the file and restart Godot—your proxy settings will be applied immediately.

3. Testing the Proxy Setup #

To confirm everything’s working, run a quick test script:

• Create a new GDScript file, attach it to a node, and paste this code:

  extends Node
  
  func _ready():
      var http = HTTPRequest.new()
      add_child(http)
      http.request("https://example.com")
      yield(http, "request_completed")
      if http.get_response_code() == 200:
          print("Proxy connection successful!")
      else:
          print(f"Proxy connection failed. Response code: {http.get_response_code()}")
  

• Run the scene. If you see "Proxy connection successful!", your setup is good to go. If not, double-check your proxy details (host, port, credentials) and ensure your proxy allows outgoing connections to the test URL.

Key Notes #

• Proxy Type Limitation: Godot 3 natively supports HTTP/HTTPS proxies only. For SOCKS proxies, you’ll need a third-party tool like proxychains (Linux) or a similar utility to forward traffic.
• Security Reminder: Your proxy password is stored in plain text in the editor_settings-3.tres file. If security is a concern, consider using an unauthenticated proxy or a dedicated proxy tool that handles credentials securely.
• Project-Specific Settings: If you need proxy config for a single project instead of the global editor, add the same network/http entries to your project’s project.godot file under the [editor] section.
