Question

由于当前项目的限制，我不得不在C ++中手工编写WebSocket协议。我能够获得授权密钥，但是当我尝试升级下一个套接字连接时，服务器在获得完整的MIME头后停止。然后当我发送任何东西后，我得到400错误。我没有从服务器得到连接已升级到WebSocket的确认。这是一个转储：

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

请注意，尽管有两个＆＃34; \ r \ n＆＃34;服务器仍未回复表示MIME标头的结尾。当我之后发送任何内容时，我收到400错误。

Answer 1

根据您的转储日志，您似乎希望使用Microsoft的语音服务将语音转换为文本。

通过使用Microsoft的语音服务，400错误意味着您没有应用所有必需的参数和HTTP标头，并且值正确。

我发现您的请求在您的请求中错过了X-ConnectionId。

根据article：

Microsoft语音服务要求所有客户端都包含唯一ID以标识连接。启动Web套接字握手时，客户端必须包含X-ConnectionId标头。 X-ConnectionId标头值必须是通用唯一标识符。不包含X-ConnectionId的Web套接字升级请求（不指定X-ConnectionId标头的值，或者不包含有效的通用唯一标识符值）将被具有400 Bad Request响应的服务拒绝。

所以我建议你可以添加识别ID并再次测试。

升级到Azure（Microsoft）websocket未得到承认
