我正在使用libwebsockets库创建一个c客户端,它将ibm-watson语音调用到文本服务器。所以我使用了minimal-ws-client-rx例如https://github.com/warmcat/libwebsockets/blob/master/minimal-examples/ws-client/minimal-ws-client-rx/minimal-ws-client.c然后我将i.address更改为“gateway-lon.watsonplatform.net”并将i.path更改为“/ speech-to-text / api / v1 / recognition ?apikey:Xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx“当我尝试运行它给我的代码时:
注意:为默认WARN创建了客户端ssl上下文:lws_client_handshake:得到错误的HTTP响应'401'ERR:CLIENT_CONNECTION_ERROR:HS:ws未经授权升级但是当我将i.port更改为80时,错误是:
注意:为默认ERR创建客户端ssl上下文:CLIENT_CONNECTION_ERROR:超时等待SSL USER:已完成失败
整个代码是:

你真的需要显示你用来连接到Speech To Text服务的代码,而不是你基于它的代码,因为那将是你编码错误的代码。如果没有我只能推测你可能做错了什么。
编号1:您应该连接到看起来像Web套接字地址而不是http地址的东西。例如。
WSS://stream.watsonplatform.net/speech-to-text/api/v1/recognize
但是有一个伦敦终点地址。
