Hi and welcome to devnet,

You should describe more precisely what you are currently doing e.g. accessing a REST service ? Sharing your code would also be good idea.

this is my QT code
class TT : public QObject
{
Q_OBJECT
public:
static QString getHtml(QString url)
{
QNetworkAccessManager *manager = new QNetworkAccessManager();
QNetworkReply reply = manager->get(QNetworkRequest(QUrl(url)));
QByteArray responseData;
QEventLoop eventLoop;
connect(manager, SIGNAL(finished(QNetworkReply)), &eventLoop, SLOT(quit()));
eventLoop.exec(); //block until finish

	responseData = reply->readAll();
	
	return QString(responseData);
}
static QString postHtml(QString url,QByteArray post_data)
{
	QNetworkAccessManager *manager = new QNetworkAccessManager();
	QNetworkRequest req;
	req.setUrl(QUrl(url));
	req.setRawHeader("Accept-Charset", "ISO-8859-1,utf-8;q=0.7,*;q=0.7");
	req.setRawHeader("Accept", "text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5");
	req.setRawHeader("Accept-Language", "zh-CN,zh;q=0.8");
	QNetworkReply *reply = manager->post(req,post_data);
	QByteArray responseData;
	QEventLoop eventLoop;

	
	connect(manager, SIGNAL(finished(QNetworkReply*)), &eventLoop, SLOT(quit()));
	eventLoop.exec();       //block until finish


	 QVariant var = reply->rawHeader("Content-Length");
	QString r="";
	while(!reply->atEnd()){
		r+=reply->read(1024);
	}

	QString rr=r;

	responseData = reply->readAll();
	
	r=responseData.data();
	return r;
}

};

the php code is my demo. the website which I want to get the data is like that.
