我想为MJPEGs
创建一个服务器,我找到了这个教程:http://www.bogotobogo.com/Qt/Qt5_QTcpServer_Client_Server.php。但是,当我从像Chrome这样的Web浏览器进行连接时(Microsoft Telnet工作正常),它会显示连接重置。
创建服务器后,我想在我的浏览器上显示MJPEGs
(就像IP相机一样):How to Create a HTTP MJPEG Streaming Server With QTcp-Server Sockets?
这是我的 Server.cpp(稍加修改) -
#include "stdafx.h"
#include "TCPServer.h"
TcpServer::TcpServer(QObject *parent) :
QObject(parent)
{
server = new QTcpServer(this);
connect(server, SIGNAL(newConnection()),
this, SLOT(newConnection()));
if (!server->listen(QHostAddress::Any, 9999))
qDebug() << "Server could not start";
else
qDebug() << "Server started!";
}
void TcpServer::newConnection()
{
QTcpSocket *socket = server->nextPendingConnection();
QByteArray header = "HTTP/1.1 200 OK\r\n";
socket->write(header);
QByteArray ContentType = "Content-Type: text/html\r\n";
socket->write(ContentType);
QByteArray Body = "Test";
socket->write(Body);
socket->flush();
socket->close();
}
答案 0 :(得分:0)
经过大量的试验和错误(以及运气)后,我找到了解决方案。代码应该像这样结束 -
...
socket->flush();
socket->waitForBytesWritten(10000);
socket->close();
编辑 -
再次尝试后,我发现了这一点 - 标题后应该有一个额外的\r\n
。所以这将有效 -
void TcpServer::newConnection()
{
QTcpSocket *socket = server->nextPendingConnection();
QByteArray header = "HTTP/1.1 200 OK\r\n";
socket->write(header);
QByteArray ContentType = "Content-Type: text/html\r\n\r\n\*Here is the edit*\";
socket->write(ContentType);
QByteArray Body = "Test";
socket->write(Body);
socket->flush();
socket->close();
}
