はじめに

  • 設定方法: VS Codeでのプロキシ設定は、ユーザーの設定ファイルでhttp.proxyおよびhttp.proxyStrictSSLを指定することで行われます。

  • SSL検証無効化: http.proxyStrictSSLをfalseに設定することで、SSL証明書の検証を無効化し、自己署名証明書を使ったプロキシとの通信を可能にします。

  • 命令構造: VS Codeの設定ファイルに以下の構造を追加します: { "http.proxyStrictSSL": false, "http.proxy": "http://USERID:[email protected]:3128" }。

  • プロキシ環境での拡張機能のインストール: 自動プロキシ検出や手動設定を行うことで、ネットワーク障害を避け、拡張機能のインストールを成功させます。

  • 環境に応じた設定: 特定のプロキシ環境では、OSのプロキシ設定変更や環境変数の再設定が必要です。

General Proxy Settings [1]

  • Hostnames Allowance: Ensure the firewall allows communication with specific hostnames like update.code.visualstudio.com.

  • Proxy Server Support: Chromium's documentation can be referred for deeper insights on proxy settings usage within VS Code.

  • Authenticating proxies: Supported methods include Basic, Digest, NTLM, and Negotiate within VS Code.

  • Command-line Proxy Configuration: Options available to bypass, disable, or configure manual proxy addresses using command-line arguments.

SSL Certificate Issues [1]

  • Certificate Trust: Add the proxy's certificate to the OS's trust chain to resolve any SSL trust issues.

  • Localhost Proxy Usage: Use --allow-insecure-localhost flag for local proxy setups.

  • Ignoring Certificate Errors: Use --ignore-certificate-errors for resolving SSL verification problems, although it's not recommended due to security risks.

Browser-based Proxy Configuration [2]

  • Network Stack: VS Code uses Chromium's network stack that leverages system-wide network settings.

  • Command-line Configuration: Options include setting direct proxy and PAC addresses.

  • Environment Variables: Proxy settings can be configured as system environment variables for broader application.

Common Errors and Troubleshooting [3]

  • XHR Errors: XHR failed issues can often be resolved by updating VS Code or modifying proxy settings.

  • automatic proxy detection: Often, setting 'Automatically detect settings' resolves connectivity issues.

  • Proxy Detection Differences: Environmental differences across Windows and Mac can affect proxy setting changes.

Proxy Configuration for Extensions [4]

  • Legacy Support: Some features, including extensions, do not support the advanced proxy configurations yet.

  • remote development: Proxy settings are vital for remote development setups like Docker and SSH connections.

  • JSON Direct Editing: Proxy settings can be edited directly in the JSON configuration file for precise updates.
