QT Http Post Request Problem

[zzzuui]

Hello I just try to process a simple Http Post request,but I always get an Error: Unknown Protocol.

This is my Code:

void Tester::ppp()
{
	QNetworkAccessManager* manager = new QNetworkAccessManager(this);
	connect(manager, SIGNAL(finished(QNetworkReply *)), this, SLOT(replyFinished(QNetworkReply *)));
 
	QUrl url = QUrl("*");
 
	QNetworkRequest request;
	request.setHeader(request.UserAgentHeader,"Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/535.2 (KHTML, like Gecko) Chrome/15.0.874.121 Safari/535.2");
	request.setHeader(request.ContentTypeHeader,"Content-Type: application/x-www-form-urlencoded");
 
	QByteArray postData;
	postData.append("email=*&");
	postData.append("password=*");
 
	manager->post(request,postData);
}
 
void Tester::replyFinished(QNetworkReply *reply)
{
	if(reply->error() != QNetworkReply::NoError)
    {
		ui.textEdit->setText("Error: " +  reply->errorString());
	}
	else
	{
		QByteArray responseData = reply->readAll();
		QString qstr(responseData);
		ui.textEdit->setText(qstr);
	}
}

void Tester::ppp()
{
	QNetworkAccessManager* manager = new QNetworkAccessManager(this);
	connect(manager, SIGNAL(finished(QNetworkReply *)), this, SLOT(replyFinished(QNetworkReply *)));

	QUrl url = QUrl("*");

	QNetworkRequest request;
	request.setHeader(request.UserAgentHeader,"Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/535.2 (KHTML, like Gecko) Chrome/15.0.874.121 Safari/535.2");
	request.setHeader(request.ContentTypeHeader,"Content-Type: application/x-www-form-urlencoded");

	QByteArray postData;
	postData.append("email=*&");
	postData.append("password=*");

	manager->post(request,postData);
}

void Tester::replyFinished(QNetworkReply *reply)
{
	if(reply->error() != QNetworkReply::NoError)
    {
		ui.textEdit->setText("Error: " +  reply->errorString());
	}
	else
	{
		QByteArray responseData = reply->readAll();
		QString qstr(responseData);
		ui.textEdit->setText(qstr);
	}
}
