qtwebapp's Introduction

THIS PROJECT IS NO LONGER MAINTAINED

QtWebApp

This library was forked from http://stefanfrings.de/qtwebapp/index-en.html

QtWebApp is a library to develop server-side web applications in C++. It depends on Qt5, minimum required version is 5.5.

The library comes with 3 components:

HttpServer
TemplateEngine
Logging

Usage

This short example demonstrates how to use the library:

class DefaultRequestHandler : public HttpRequestHandler
{
public:
	void service(HttpRequest &request, HttpResponse &response);
}

void DefaultRequestHandler::service(HttpRequest &request, HttpResponse &response)
{
	response.write("<html><body><h1>" + request.getPath() + "</h1></body></html>");
}

int main(int argc, char **argv)
{
	QCoreApplication app(argc, argv);
	
	QSettings *config = new QSettings;
	// ...
	
	new HttpListener(config, new DefaultRequestHandler);
	return app.exec();
}

You can the compile it using cmake, like this:

# ...
find_package(QtWebApp REQUIRED COMPONENTS HttpServer)
add_executable(thinkofabettername main.cpp)
target_link_libraries(thinkofabettername ${QtWebApp_LIBRARIES})
# ...

Build

QtWebApp uses CMake as the build system. To compile, simply run:

mkdir build && cd build
cmake -DCMAKE_BUILD_TYPE=Release ..
make -j4
sudo make install

qtwebapp's Issues

How to support gui thread.

When I handle a new connection,I want use qtwebkit to get a page and send back in this connection,but got the error:

ASSERT failure in QWidget: "Widgets must be created in the GUI thread.", file kernel\qwidget.cpp, line 1133

Is it possible to detect request cancellation?

Hello, we need a way to detect when clients abort their connection. For example in ASP there is a concept of cancellatkiontoken. Does this library have anything similar?

Fix GitHub Actions on Windows

The CI fails on Windows with some weird linker error. I have no experience whatsoever with Windows, so if someone knows how to fix this, please tell me / open a PR!

Is it possible to send button click signal to qt side without forms?

Hello,

I want to implement multiple buttons on one page for ex. to control blind rollers, by pressing a button the blind goes up by few centimeters, by press and hold it continously goes up etc.
Is it possible to do this mechanic using this library? I only saw examples by sending data using forms and post/get method but can you use javascript to send data directly to c++? or plain input type button without the need of form?
Thanks for response :)

StaticFileController

QtWebApp/httpserver/staticfilecontroller.cpp
the code here:

if (!cfg.fileName.isEmpty() && !(docroot.startsWith(":/") || !docroot.startsWith("qrc://"))) {
	// Convert relative path to absolute, based on the directory of the config file.
	if (QDir::isRelativePath(docroot)) {
		QFileInfo configFile(cfg.fileName);
		docroot = QFileInfo(configFile.absolutePath(), docroot).absoluteFilePath();
	}
}`

The first judgment condition is wrong. Suppose my [docroot] is "../location/staticfiles", it returns false.

using any SQL database in project

dear friend
despite this is newest fork of QtWebApp, i wonder if you can help.
in short sentence, exactly where should i create a database connection in project?
Qt does not allow to use database connection that is created in a controller to be executed in the HttpRequestHandler::service()
even i tried to have db in the HttpRequestHandler itself. but again db queries don't exec inside service() method and all ways throws this error:
QSqlDatabasePrivate::database: requested database does not belong to the calling thread.

HTTP POST request

Does it support HTTP POST request?

Upstream moved from Website-based ZIP Download to a Git Repository

Hello msrd0,
sorry for the bad title, I cannot change it anymore. I did not find contact information, otherwise I would have sent you an email.

I just wanted to tell you that QtWebApp is now officially available on my own site on https://github.com/StefanFrings/QtWebApp/

As far as I can see, you added support for CMAKE, which is a good reason to keep your repo. Right?

Qt 6 build relies on qt5compat

Currently QtWebApp built with Qt 6 needs the compatibility module. Over time it would be great to get rid of the dependency. The question is how. The compatibility is needed for QTextCodec which is used by the template engine. I'm unsure whether it would be good enough to drop the codec conversion API and require UTF-8 (I think this sounds sensible) or how important it is to keep compatibility here.
