Simple HTTP Server▲
This example shows how to set up a server using the https:// class. The server is bound to an incoming port using the listen() function, and the route() function is used to add a handler for each of several different incoming URLs. For one of the URLs, "/auth", https:// is used.
Sélectionnez
const auto sslCertificateChain =
QSslCertificate::fromPath(QStringLiteral(":/assets/certificate.crt"));
if (sslCertificateChain.empty()) {
qWarning() << QCoreApplication::translate("QHttpServerExample",
"Couldn't retrieve SSL certificate from file.");
return -1;
}
QFile privateKeyFile(QStringLiteral(":/assets/private.key"));
if (!privateKeyFile.open(QIODevice::ReadOnly)) {
qWarning() << QCoreApplication::translate("QHttpServerExample",
"Couldn't open file for reading: %1")
.arg(privateKeyFile.errorString());
return -1;
}
httpServer.sslSetup(sslCertificateChain.front(), QSslKey(&privateKeyFile, QSsl::Rsa));
privateKeyFile.close();
const auto sslPort = httpServer.listen(QHostAddress::Any);
if (!sslPort) {
qWarning() << QCoreApplication::translate("QHttpServerExample",
"Server failed to listen on a port.");
return -1;
}In the above example QSslConfiguration is used to show how to create an SSL configuration for a https:// to serve HTTPS traffic.
Sélectionnez
httpServer.afterRequest([](QHttpServerResponse &&resp) {
resp.setHeader("Server", "Qt HTTP Server");
return std::move(resp);
});The above example shows how to use the afterRequest() function of the https:// to change the https:// object after it has been handled by the route() function. It demonstrates how HTTP headers can be added to the response.
