Question

获取提供的示例的源代码here，转换为Swift 3并应用我生成的已升级Twilio帐户的令牌。

尝试拨打电话时会发出声音，但在尝试访问HTTP/1.0 400 Bad request时会失败并显示https://matrix.twilio.com/2012-02-09/AC ...。

这是尝试拨打电话后的日志 -

可能是什么问题？

Answer 1

很难看到代码（使用您输入的参数）来确定真正的问题是什么。但是我会努力的。您的日志文件中存在两个问题：

400 BAD REQUEST表示：HTTP POST或PUT中提供的数据验证失败。

longPollConnection : didFailWithError表示：服务器不可用，不响应和/或发送新信息。 --------------------------------------------

2016-10-16 18:32:14.030074 MyApp[577:121739] [DEBUG TCEventStream] Inside longPollConnection:didFailWithError:, stream <TCEventStream: 0x17427cbc0> disconnected, error Error Domain=com.twilio.client.TCHttpErrorDomain Code=4 "HTTP server returned non-success status" UserInfo={com.twilio.client.TCHttpStatusCodeKey=400, NSLocalizedDescription=HTTP server returned non-success status}

以下是可能的解决方案：

如果有必要，请更新您的Podfile：Pod install vs. pod update



阅读有关可能出现问题的文章：What is HTTP Long Polling?



观看此有用视频：Advanced Debugging and the Address Sanitizer



仔细检查以下参数：Voice: Twilio's request



如果您正在编写自己的 客户端 ，则需要将HTTP Content-Type标头设置为 application/x-www-form-urlencoded 根据您的要求。



您应该检查response正文以获取详细信息。

希望这有帮助！

Answer 2

在iOS 10中，您应该使用PushKit来处理传入VoIP呼叫的推送通知。因此，当您针对iOS 10 SDK构建应用程序时，您需要转移到PushKit（可以一直支持iOS 8，但是一旦转移到iOS 10，我们的建议是将您的最低部署目标更新到iOS 9）。

Answer 3

我相信您最好的选择是更新到Programmable TwilioVoice SDK以避免将来出现此类问题，我们开始使用TwilioClient在我们的应用程序中遇到类似的问题。 Twilio不再支持TwilioClient SDK。

请查看以下内容：https://www.twilio.com/docs/voice/client/ios

切换到最新的SDK要求后端/前端进行一些更改，因为它们已弃用了TCDevice，TCConnection等类。

请让我知道我是否可以帮上忙。祝好运。
