cv2.imread cannot open files under non-ASCII (e.g. Chinese) paths on
Windows, so decode_qrcode_from_path() always returned None when the
project lived under a directory like D:\视频全平台同步\, and the
terminal QR re-print silently failed. Use np.fromfile + cv2.imdecode
instead, which handles arbitrary paths.
The WeChat Channels login page now embeds the QR code in an
open.weixin.qq.com/connect/qrconnect iframe whose img.qrcode src is a
relative path (e.g. /connect/qrcode/xxxx) instead of an inline
data:image/ URL. The previous logic looked for a login-for-iframe
frame and only accepted data:image/ sources, so login always failed
with '未获取到视频号登录二维码地址'.
Changes:
- Detect the qrconnect iframe and resolve the relative img src,
download the QR image via the browser context and convert it to a
data URL so downstream save/decode logic stays unchanged
- Keep the legacy login-for-iframe and selector fallbacks
- Tolerate QR extraction failure: the login flow now continues and
lets the user scan directly in the headed browser instead of
aborting the whole login
