H5 调 accreditlogin 仍无反应。加临时 print 排查链路： AccreditLoginHandler: - 入口"H5 调用命中 ✅" → 确认 WVJB 协议握手 + handler 注册 OK - canImport(WechatOpenSDK) 真值 → 确认 SDK 是否真链接进了 binary - Task @MainActor 入口 → 确认 actor hop 没卡死 - 失败分支区分用户取消（errCode -2）/ 其它 WeChatManager.authorize(): - isWXAppInstalled() → 用户手机是否真装了微信 - getVersion() → 加载的 SDK 版本字符串（验证链接的 framework） - topmostViewController() nil 检测 → present 上下文是否拿到 - sendAuthReq completion success=true/false → SDK 是否成功拉起微信 app 跑一次 H5 调 accreditlogin 看 Xcode console 输出序列，按 print 出现/缺失 精确定位卡点（H5 没调进来 / SDK 未链接 / VC 拿不到 / SDK 拉起失败）。 排查完成后可删除 print。 Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
