升級到Azure（微軟）websocket不確認

由於當前項目的限制，我不得不手動編寫C++中的WebSocket協議。我能夠獲得授權密鑰，但是當我嘗試升級下一個套接字連接時，服務器在獲得完整的MIME頭後停頓。然後當我發送任何東西后，我得到一個400錯誤。我沒有從服務器獲得連接已升級到WebSocket的確認。這裏是一個轉儲：升級到Azure（微軟）websocket不確認

HTTP/1.1 400 Bad Request 
Exception: 4xx Client failure

請注意，服務器不會盡管獲得兩個答覆爲「\ r \ n」表示MIME頭的一端。當我發送任何東西后，我得到一個400錯誤。

根據您的轉儲日誌，似乎您想使用Microsoft的語音服務將語音轉換爲文本。

通過使用Microsoft的語音服務，400錯誤意味着您沒有應用所有必需的參數和HTTP標頭，並且這些值是正確的。

我發現您的請求在您的請求中遺漏了X-ConnectionId。

根據這一article：

微軟語音服務要求所有的客戶包括一個獨特的ID來識別連接。啓動Web套接字握手時，客戶端必須包含X-ConnectionId標頭。 X-ConnectionId標頭值必須是通用唯一標識符。不包含X-ConnectionId的Web套接字升級請求，沒有指定X-ConnectionId標頭的值或不包含有效通用唯一標識符值的Web套接字升級請求將被具有400錯誤請求響應的服務拒絕。

所以我建議你可以添加識別ID並再次測試。
