I'm trying to use QtWebApp to create a simple web app server, but it shows some error that i could not figure how to fix, any hint how to fix this?
这是我所做的:
=从 http://stefanfrings.de/qtwebapp/
=使用qmake和make编译QtWebApp，成功完成
= compiling QtWebApp using qmake and make, completed successfully
=创建一个新的qwtest.pro，其中包含:
= create a new qwtest.pro, containing:
QT += core network
QT -= gui
TARGET = qwtest
CONFIG += console
CONFIG -= app_bundle
TEMPLATE = app
SOURCES += main.cpp
=创建源文件main.cpp，其中包含:
= create source file main.cpp, containing:
#include "../v1.3.2 2014-01-08/lib/bfHttpServer/src/httplistener.h"
#include <QtCore>
class MyController: public HttpRequestHandler {
private:
QCoreApplication *app;
public:
MyController(QCoreApplication *app) : app(app) {}
void service(HttpRequest& request, HttpResponse& response);
};
void MyController::service(HttpRequest& request, HttpResponse& response) {
QByteArray path=request.getPath();
QByteArray username=request.getParameter("username");
response.setHeader("Content-Type", "text/html; charset=ISO-8859-1");
response.setCookie(HttpCookie("myCookie","any value",600));
response.write("<html><body>");
response.write("Hello ");
response.write(username);
response.write("</body></html>");
}
int main(int argc, char *argv[]) {
QCoreApplication* app=new QCoreApplication(argc,argv);
QSettings* settings=new QSettings("configfile.ini",QSettings::IniFormat,app);
MyController* controller=new MyController(app);
HttpListener* listener=new HttpListener(settings,controller,app);
return app->exec();
}
=使用qmake和make

推荐答案
我忘记添加库，这是我应该在qwtest.pro文件上添加的
I forgot to add the libs, this what i should add on the qwtest.pro file
LIBS += /home/foo/qtwebapp/qwtest/http*.o \
/home/foo/qtwebapp/qwtest/moc_*.o \
/home/foo/qtwebapp/qwtest/log*.o \
/home/foo/qtwebapp/qwtest/f*.o \
/home/foo/qtwebapp/qwtest/template*.o \
/home/foo/qtwebapp/qwtest/du*.o \
/home/foo/qtwebapp/qwtest/request*.o \
/home/foo/qtwebapp/qwtest/session*.o \
/home/foo/qtwebapp/qwtest/static*.o
