C++ 如何在Qt5中通过http连接到推送服务器
回顾QNetworkAccessManager，我没有看到任何与“推送”相关的内容。 与POST或GET不同，使用“推送”http连接时，您需要维护连接，以便能够从服务器接收定期更新。 Qt5中HTTP REST“推送”客户端连接使用的正确函数是什么？或者可能是一个持久的http连接？C++ 如何在Qt5中通过http连接到推送服务器,c++,qt,push,qt5,qtnetwork,C++,Qt,Push,Qt5,Qtnetwork,回顾QNetworkAccessManager，我没有看到任何与“推送”相关的内容。 与POST或GET不同，使用“推送”http连接时，您需要维护连接，以便能够从服务器接收定期更新。 Qt5中HTTP REST“推送”客户端连接使用的正确函数是什么？或者可能是一个持久的http连接？>如何使用QNetworkAccessManager连接到http推送服务器？ > How would I use QNetworkAccessManager to connect to an http pu

<thiago> it will keep giving you data as long as there's data to be given

<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

<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
*** Signoff: katmandoo (Ping timeout: 240 seconds)
<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

你需要发送什么HTTP命令？

只要有数据要提供，它就会一直给你提供数据

***签准：filipesaraiva（读取错误：对等方重置连接）
数据结束后，可以关闭或重新使用连接。但是你不能也不应该关心它。
QNAM中没有超时机制

>除非另有规定，否则无FIN/ACK？
这是一个低得多的水平
当服务器说HTTP请求/应答结束时，HTTP请求/应答结束
>连接无法关闭。无财务/确认
在HTTP/1.1下，当达到Content Length中指定的字节数时，它结束
***签署：加德满都（Ping超时：240秒）
或者分块编码表示这是最后一块
如果出现上述任一情况，QNetworkReply将发出结束信号
然后QNAM可以对套接字执行任何操作
