Twilio iOS SDK在撥出電話時失敗並顯示“400 Bad request”

Question

獲取此處提供的示例源代碼，轉換為Swift 3並應用我生成的升級后的Twilio帳戶令牌。

嘗試撥打電話時，它會播放聲音，但在嘗試訪問https://matrix.twilio.com/2012-02-09/AC ...時，會因HTTP/1.0 400 Bad request失敗。

這是試圖打電話后的日志 -

可能是什么問題？

Answer 1

很難看到代碼（使用您輸入的參數）來確定真正的問題是什么。 但是我會努力的。 您的日志文件中有兩個問題：

1. 400 BAD REQUEST意味着：HTTP POST或PUT給出的數據驗證失敗。

2. longPollConnection : didFailWithError表示：服務器不可用，不響應和/或發送新信息。 --------------------------------------------

    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} 

以下是可能的解決方案：

1. 重置Xcode和iOS模擬器： 如何重置Xcode和iOS模擬器和SO帖子

2. 如果有必要，請更新Podfile： Pod安裝與pod更新

3. 閱讀有關可能出現的問題的文章： 什么是HTTP長輪詢？

4. 觀看此有用視頻： 高級調試和地址清理程序

5. 仔細檢查這些參數： 語音：Twilio的請求

6. 如果您正在編寫自己的客戶端 ，則需要將HTTP Content-Type標頭設置為application/x-www-form-urlencoded以滿足您的請求。

7. 您應該檢查response正文以獲取詳細信息。

還有其他有用的參考：

希望這可以幫助！

Answer 2

在iOS 10中，您應該使用PushKit來處理傳入VoIP呼叫的推送通知。 因此，當您針對iOS 10 SDK構建應用程序時，您需要轉移到PushKit（可以一直支持iOS 8，但是一旦轉移到iOS 10，我們的建議是將您的最低部署目標更新到iOS 9）。

Answer 3

我相信您最好的選擇是更新到Programmable TwilioVoice SDK以避免將來出現此類問題，我們開始在使用TwilioClient的應用程序中遇到類似的問題。 Twilio已停止支持TwilioClient SDK。

請查看： https ： //www.twilio.com/docs/voice/client/ios

切換到最新的SDK需要從后端/前端進行一些更改，因為他們已經棄用了類，如TCDevice，TCConnection等。

如果我有所幫助，請告訴我。 祝好運。
