Key Features

• Multi-platform Support: Works on Windows, macOS, and Linux.
• Wide Resource Support: Handles video, audio, images, m3u8, and live streams.
• Platform Compatibility: Supports resources from platforms like WeChat Video Accounts, WeChat Mini Programs, Douyin (TikTok), Kuaishou, Xiaohongshu, Kugou Music, and QQ Music.
• Proxy Sniffing: Supports setting up proxies to capture and retrieve resources from restricted networks.

The application includes various configuration options.

Important: Always click '保存' (Save) after making changes to ensure settings are applied.

For detailed information on any specific configuration item, hover your mouse over the '?' icon next to the setting to view its description.

To correctly capture and download resources (videos, audio, images, etc.) from platforms like WeChat Video Accounts, Douyin, or web pages, follow these steps:

1. Installation: During installation, you must allow the installation of the certificate file and grant network access permissions.
2. Start Proxy: Open the software and click "启动代理" (Start Proxy) located at the top left of the home page.
3. Select Resource Type: Choose the type of resource you want to capture (e.g., video, audio, image, m3u8, live stream). You can leave it as the default (All).
4. Browse Resources: Open your target resource page (e.g., a video in a WeChat Mini Program or a website) in an external browser or app.
5. View Results: Return to the res-downloader home page to see the captured resource list.

Select the appropriate installation file based on your operating system and architecture:

• Windows: Download files ending in .exe. For most modern systems, look for files containing win_amd64.exe or x64-installer.exe.
• macOS: Download the .dmg file.
• Linux: Download the executable or installation package corresponding to your specific Linux distribution.

If you encounter 'Not a private link' errors, the certificate is likely not installed correctly. For macOS (V3+ versions), you can install the certificate and mark it as trusted by running this command in the terminal. Follow the prompts to enter your password:

sudo security add-trusted-cert -d -r trustRoot -k /Library/Keychains/System.keychain /Users/$(whoami)/Library/Preferences/res-downloader/cert.crt && touch /Users/$(whoami)/Library/Preferences/res-downloader/install.lock && echo "安装完成"

Follow these steps to capture and download resources:

1. Installation Requirements: During installation, you must agree to install the certificate files and allow network access.
2. Launch the Software:
   • Windows: For the first use, right-click the application and select Run as Administrator.
   • Important: Before installing on Windows, close all security/antivirus software.
   • Mac: If the software fails to intercept traffic, please disable your firewall.
3. Start Proxy: Click the “启动代理” (Start Proxy) button in the top-left corner of the application.
4. Capture Resources: Open the source you want to capture (e.g., WeChat Video Accounts, web pages, mini-programs, etc.).
5. View Resources: Return to the software's home page to see the list of captured resources.

By default, TypeScript treats .vue imports as generic Vue components, which means you won't get full prop type validation when importing components into .ts files (e.g., when using manual h(...) calls).

To enable Volar's Take Over mode and get actual prop types, follow these steps in VS Code:

1. Open the Command Palette (Ctrl+Shift+P or Cmd+Shift+P).
2. Run Extensions: Show Built-in Extensions.
3. Find the extension named TypeScript and JavaScript Language Features.
4. Right-click it and select Disable (Workspace).
5. Open the Command Palette again and run Developer: Reload Window to reload the VS Code window.

This allows Volar to handle both Vue and TypeScript files directly, providing better type information for .vue imports.

Once the proxy is enabled, the software can intercept resources from various sources:

• WeChat Channels (视频号): Open the Channels feature in WeChat, and the intercepted video/media resources will appear in the software's list.
• Web Browsers: Open any website (e.g., https://www.baidu.com/) in a standard browser or a built-in browser within another app. The resources requested by the page will be captured.
• Other Apps: The same interception method works for resources within Mini Programs (小程序), Official Accounts (公众号), Douyin (抖音), Xiaohongshu (小红书), QQ Music (QQ音乐), Kugou (酷狗), and similar applications.

Installation methods vary depending on your distribution and file type:

Ubuntu (using .deb package)

Use apt to install the .deb file:

sudo apt install res-downloader_3.0.2_linux_x64.deb

Generic Linux (using executable binary)

If you have a standalone executable, grant it execution permissions and run it with sudo:

chmod +x ./res-downloader_3.0.2_linux_x64
sudo ./res-downloader_3.0.2_linux_x64

Note: Replace the filename in the commands above with the exact version you downloaded.

After resources have been intercepted and listed in the software, you can save them to your computer:

1. Locate the specific video or resource you wish to save from the intercepted list.
2. Click the 下载 (Download) button associated with that resource to save it to your local machine.
