Technical Principle

Based on Playwright browser automation, simulates real user operations on the WeChat Channels Creator Center (https://channels.weixin.qq.com):

  4. Supports scheduled publishing, original content declaration, and adding to collections

Prerequisites

2. Obtain Login Cookie for First-Time Use

bash
python .opencode/skills/auto-weixin-video/scripts/get_cookie.py
After execution, a browser will open. Log in via WeChat QR code, and the cookie will be automatically saved after successful login.

Workflow

Step 1: Verify Login Status

Check if the cookie exists and is valid:
bash
python .opencode/skills/auto-weixin-video/scripts/check_cookie.py
If the cookie is invalid, re-obtain it:
bash
python .opencode/skills/auto-weixin-video/scripts/get_cookie.py

Step 2: Prepare Video Files

Video file requirements:
  • Format: 
    .mp4
    (recommended)
  • Resolution: Recommended 1080x1920 (vertical 9:16) or 1920x1080 (horizontal 16:9)
  • Duration: Best within 1 minute

Step 3: Publish Video

bash
python .opencode/skills/auto-weixin-video/scripts/publish.py \
    --video "video file path" \
    --title "video title" \
    --tags "topic1,topic2,topic3" \

Notes

  1. Cookie Validity Period: WeChat cookies have a relatively short validity period, so it is recommended to check before each use
  2. Publishing Frequency: It is recommended to control the publishing frequency to avoid being identified as abnormal behavior by the platform
  3. Short Title: The system will automatically generate a short title of 6-16 characters from the main title
  4. Number of Topics: It is recommended to add 3-5 relevant topics
  5. Original Content Declaration: Checking the original content option must comply with the platform's original content specifications, otherwise penalties may be imposed
  6. Collections: If the account has collections, the video will be automatically added to the first collection
