查看 QNetworkAccessManager 我没有看到任何与“推送”相关的内容。 http://qt-project.org/doc/qt-5/qnetworkaccessmanager-members.html 与 POST 或 GET 不同，使用“推送”http 连接时，您要保持连接，以便可以从服务器接收定期更新。 Qt5 中用于 HTTP REST“推送”客户端连接的正确函数是什么？或者可能是持久的 http 连接？
最佳答案

<thiago> pEYEd: what HTTP command do you need to send?
> thiago good point. I am not sure. It looks like json https://www.cryptsy.com/pages/pushapi
<thiago> pEYEd: JSON is not an HTTP command
<thiago> try again: what HTTP command do you need to send?
> i know
<thiago> pEYEd: let me try this: have you tried to simply get() the page?
> it looks like POST
> http://pusher.com/docs/client_api_guide/client_connect
<thiago> then use post()
> thiago will it automatically do a persistant connection?
<thiago> pEYEd: what exactly do you need to happen?
<thiago> it will keep giving you data as long as there's data to be given
> but it can't time out
<thiago> once the data ends, the connection may be closed or reused. But you cannot and must not care about it.
<thiago> there's no timeout mechanism in QNAM
> no FIN/ACK unless specified?
<thiago> that's at a much lower level
<thiago> the HTTP request/reply ends when the server says it ends
> the connection can't close. no fin/ack
<thiago> under HTTP/1.1, it ends when the number of bytes specified in Content-Length is reached
<thiago> or the chunked encoding says it's the last chunk
<thiago> if either of those conditions happen, the QNetworkReply signals the end
<thiago> then QNAM can do whatever it wants to the socket
