我使用这个代码做一个简单的HTTP邮政(登录)
QNetworkAccessManager *nwam = new QNetworkAccessManager;
QNetworkRequest request(QUrl("http://localhost/laptop/trylogin.php"));
QByteArray data;
QUrl params;
QString userString(user);
QString passString(pass);
params.addQueryItem("user", userString );
params.addQueryItem("pass", passString );
data.append(params.toString());
data.remove(0,1);
QNetworkReply *reply = nwam->post(request,data);
如果记录succeedes与否,我该如何发送和阅读在Qt的反应?
