ios使用微信登录sdk可以拉起微信但是闪一下就退了，无法正确获取授权页面该怎么办？

环境描述：系统IOS 12.4 ，微信版本 7.0.8， SDK 1.8.6, 错误日志： Error:set token fail, errCode:4, errLog:wx token[] or contextId[(null)] is nil 状态描述：可以看到有跳转微信的过程，但是不能正确获取微信授权界面。但是又能拿到相应的返回值，很奇怪，有人遇到过嘛？相关代码： //三个重写的API func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool { returnWXApi.handleOpen(url, delegate: self) // func application(_ application: UIApplication, open url: URL, sourceApplication: String?, annotation: Any) -> Bool { // return WXApi.handleOpen(url, delegate: self) // } func application(_application: UIApplication, handleOpen url: URL) -> Bool{ returnWXApi.handleOpen(url, delegate: self) func application(_ application: UIApplication, continueuserActivity: NSUserActivity, restorationHandler: @escaping ([UIUserActivityRestoring]?) -> Void) -> Bool { logger.info("调用useractivity" returnWXApi.handleOpenUniversalLink(userActivity, delegate: self) //回调 func onResp(_ resp: BaseResp) { logger.info(String(format: "返回的resp是：%p", resp)) //微信登录 ifresp is SendAuthResp { logger.info("微信登录接口" // switch(resp.errCode){ // case 0: // let response = resp as! SendAuthResp // NotificationCenter.default.post(name: NSNotification.Name(rawValue: "WXLoginSuccessNotification"), object: response.code) // break // case -4: //用户拒绝 // NotificationCenter.default.post(name: NSNotification.Name(rawValue: "WXLoginDenyNotification"), object: nil) // break // case -2: //用户取消 // NotificationCenter.default.post(name: NSNotification.Name(rawValue: "WXLoginCancelNotification"), object: nil) // break // default: // break // } ifresp.errCode == 0 && resp.type == 0 {//授权成功 let response = resp as! SendAuthResp NotificationCenter.default.post(name: NSNotification.Name(rawValue: "WXLoginSuccessNotification"), object: response.code) // end of internal if return // end of external if // end of onResp // send @IBAction func wechatLogin(_ sender: LGButton) { sender.isLoading = true ifWXApi.isWXAppInstalled() { let app = UIApplication.shared ifapp.canOpenURL(URL.init(string: WEIXIN_SCHEME)!) { let req = SendAuthReq.init() req.scope = "snsapi_message,snsapi_userinfo,snsapi_friend,snsapi_contact" req.state = "\(arc4random()%100)" logger.info("准备开启微信登录!" let deadlineTime = DispatchTime.now() + .seconds(1) DispatchQueue.main.asyncAfter(deadline: deadlineTime) { //停止转圈圈 WXApi.send(req, completion: { (success) in sender.isLoading = false logger.info("成功获取微信app的授权，开始向微信服务器发起请求!" })} } else if#available(iOS 10.0, *) { UIApplication.shared.open(URL.init(string: "http://weixin.qq.com/r/qUQVDfDEVK0rrbRu9xG7")!, options: [:], completionHandler: nil) } else // Fallback on earlier versions UIApplication.shared.openURL(URL.init(string: "http://weixin.qq.com/r/qUQVDfDEVK0rrbRu9xG7")!) else self.sendmsgToWxServer() sender.isLoading = false // 登录成功之后 @objc func WXLoginSuccess(notification:Notification) { logger.info("WXLoginSuccess开始执行" let code = notification.object as! String let requestUrl = "https://api.weixin.qq.com/sns/oauth2/access_token?appid=\(WX_APPID)&secret=\(WX_APPSecret)&code=\(code)&grant_type=authorization_code" DispatchQueue.global().async { let requestURL: URL = URL.init(string: requestUrl)! let data = try? Data.init(contentsOf: requestURL, options: Data.ReadingOptions()) //TODO：从微信获取到的用户信息，然后再回传到app的后台服务器 DispatchQueue.main.async { let jsonResult = try!
