Twilio iOS SDK在傳出呼叫時出現「400 Bad request」失敗

將提供的示例源代碼here轉換爲Swift 3並應用我生成的升級Twilio帳戶的令牌。Twilio iOS SDK在傳出呼叫時出現「400 Bad request」失敗

當試圖撥打電話時，它播放聲音，但在嘗試訪問https://matrix.twilio.com/2012-02-09/AC ...時失敗，出現HTTP/1.0 400 Bad request。

這裏的日誌試圖撥打電話後 -

什麼可以是問題？

您是否能夠讀取響應中發送的錯誤消息（除了400錯誤代碼）？像這樣顯示在這裏：https://www.twilio.com/docs/api/errors#debugging-calls-to-the-rest-api – aksh1t

我沒有檢查實際的請求/響應，但不是日誌中寫的是什麼？ – Kof

很難看不到一個代碼（帶有你輸入的參數）來確定真正的問題是什麼。但是我會努力的。有你的日誌文件中的兩個問題：

  1. 400 BAD REQUEST是指：在HTTP POST或PUT驗證失敗給出的數據。

  2. longPollConnection : didFailWithError表示：服務器不可用並且不響應和/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爲您提供：

  1. 復位Xcode和iPhone模擬器：How to Reset Xcode and the iOS Simulator和SO post

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

  3. 閱讀有關可能出現的問題的文章：What is HTTP Long Polling?

  4. 關注此有用的視頻：Advanced Debugging and the Address Sanitizer

  5. 仔細檢查這些參數：Voice: Twilio's request

  6. 如果你正在編寫你自己的客戶端，你需要設置HT TP內容類型頭到application/x-www-form-urlencoded爲您的請求。

  7. 您應該檢查一個response正文的細節。

還有其他有用的參考資料：

¡希望這有助於！

不，我正在使用他們的官方SDK，pod'TwilioClient'。此外，它發生在他們的官方演示項目上。 – Kof

@Kof您是否更改過Phone.swift中定義的常量？請發佈代碼片段。 – andy

+0

是的，在'Phone.swift'上使用我的憑證。沒有什麼可展示的，我只是分配了我的SID並放置了我的後端網址。我的Node.js後端使用Twilio Node.js SDK生成一個有效的標記，然後將其返回到應用程序並用於創建連接。 – Kof

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，需要轉移到PushKit（可以一直支持到iOS 8，但是一旦移動到iOS 10，我們的建議是將最低部署目標更新爲iOS 9）。
