Qt开发http server，兼容Qt4（QtWebApp）

下载QtWebApp

http://www.stefanfrings.de/qtwebapp/QtWebApp.zip

解压后将httpserver中的文件引入到项目中
编写CHttpServer类，继承自HttpRequestHandler，并重新实现service接口，代码如下：

CHttpServer.h

#ifndef CHTTPSERVER_H
#define CHTTPSERVER_H

#include <QObject>
#include "QtWebApp/httpserver/httprequesthandler.h"

using namespace stefanfrings;

class CHttpServer : public HttpRequestHandler
{
    Q_OBJECT
public:
    explicit CHttpServer(QObject *parent = 0);
    
    void service(HttpRequest& request, HttpResponse& response);
signals:
    
public slots:
    
};

#endif // CHTTPSERVER_H

CHttpServer.cpp

#include "chttpserver.h"

CHttpServer::CHttpServer(QObject *parent) :
    HttpRequestHandler(parent)
{

}

void CHttpServer::service(HttpRequest& request, HttpResponse& response)
{
    // Get a request parameters
    QByteArray username=request.getParameter("username");
    QByteArray path = request.getPath();

    // Set a response header
    response.setHeader("Content-Type", "text/html; charset=UTF-8");

    // Generate the HTML document
    response.write("<html><body>");
    response.write("Hello ");
    response.write(username);
    response.write(" path="+path);
    response.write("</body></html>");
}

main.cpp

#include "widget.h"
#include <QApplication>
#include <chttpserver.h>
#include <QDebug>

#include "QtWebApp/httpserver/httplistener.h"

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    Widget w;
    w.show();

    new HttpListener(
        new QSettings("E:/test/test1/cfg.ini",QSettings::IniFormat,&app),
        new CHttpServer(&app),
        &app);
    
    return app.exec();
}

cfg.ini为配置文件，其内容如下：

;host=192.168.0.100
port=8088
minThreads=4
maxThreads=100
cleanupInterval=60000
readTimeout=60000
maxRequestSize=16000
maxMultiPartSize=10000000
;sslKeyFile=ssl/my.key
;sslCertFile=ssl/my.cert

运行程序后访问：

http://127.0.0.1:8080/path?username=test
