QHttp *http;
http=new QHttp();
QUrl *url=new QUrl("http://feymercurial.com/forum/profile.php?mode=viewprofile&u=873");

QFileInfo fileinfo(url->path());


QFile *file = new QFile(fileinfo.fileName());
file->open(QIODevice::WriteOnly);

http->setHost(url->host(),80);
int httpGetId=http->get(url->path(),file);
qDebug() << httpGetId;

--------------------------------


QUrl *url=new QUrl("http://feymercurial.com/forum/profile.php?mode=viewprofile&u=873");

Are you implementing some spam related software?

[fengtian.we]

NO NO~ haha~

my Boss will salesmanship some our product, so let me find MSN number~

our product is about game WOW.

I think this not spam related software

[fengtian.we]

help me ~ please~

[wysota]

Start by moving that QUrl object to stack.Then connect to QHttp signals that transmit information about the response header and display the header contents, it'll probably tell you something important (at least the status code).

[fengtian.we]

ok , let me try

[fengtian.we]

My case：
page with parameter can download:http://www.a2gold.com/index_en.php
page without parameter,can't download:http://feymercurial.com/forum/profil...wprofile&u=873


Code：

int main(int argc,char *argv[])
{
QApplication qapp(argc,argv);
QHttp *http;
http=new QHttp();
 
//QUrl *url=new QUrl("http://feymercurial.com/forum/profile.php?mode=viewprofile&u=873");   [COLOR="red"]  //this can't download. [/COLOR]
 
QUrl *url=new QUrl("http://www.a2gold.com/index_en.php");   [COLOR="Red"]  //this can download. [/COLOR]
 
QFileInfo fileinfo(url->path());
 
 
QFile *file = new QFile(fileinfo.fileName());
file->open(QIODevice::WriteOnly);
 
http->setHost(url->host(),80);
int httpGetId=http->get(url->path(),file);
qDebug() << httpGetId;
 
return qapp.exec();
}

int main(int argc,char *argv[])
{
QApplication qapp(argc,argv);
QHttp *http;
http=new QHttp();

//QUrl *url=new QUrl("http://feymercurial.com/forum/profile.php?mode=viewprofile&u=873");   [COLOR="red"]  //this can't download. [/COLOR]

QUrl *url=new QUrl("http://www.a2gold.com/index_en.php");   [COLOR="Red"]  //this can download. [/COLOR]

QFileInfo fileinfo(url->path());


QFile *file = new QFile(fileinfo.fileName());
file->open(QIODevice::WriteOnly);

http->setHost(url->host(),80);
int httpGetId=http->get(url->path(),file);
qDebug() << httpGetId;

return qapp.exec();
}

how can i download a page with a parameter?

Simply dont use path(), instead use text parsing, here is an example:

bool HttpGetFile::ParseUrl( const QString& qstrUrlIn, int& iError )
{
	QString qstrUrl = qstrUrlIn;
 
	QUrl qUrl( qstrUrl );
 
	if( qstrUrlIn.length() == (qUrl.scheme().length() + 3 + qUrl.host().length()) )
	{
		qstrUrl += "/";
		qUrl = qstrUrl;
	}
 
	if( !qUrl.isValid() )
	{
		iError = 8;
		return false;
	}
 
	if( qUrl.scheme() != "http" )
	{
		iError = 9;
		return false;
	}
 
	qstrHost = qUrl.host();	
	qstrPath = qstrUrl.remove( 0, 7 + qstrHost.length() );// 7 == http://   
 
	return true;
}

bool HttpGetFile::ParseUrl( const QString& qstrUrlIn, int& iError )
{
	QString qstrUrl = qstrUrlIn;
	
	QUrl qUrl( qstrUrl );
	
	if( qstrUrlIn.length() == (qUrl.scheme().length() + 3 + qUrl.host().length()) )
	{
		qstrUrl += "/";
		qUrl = qstrUrl;
	}
	
	if( !qUrl.isValid() )
	{
		iError = 8;
		return false;
	}
	
	if( qUrl.scheme() != "http" )
	{
		iError = 9;
		return false;
	}
	
	qstrHost = qUrl.host();	
	qstrPath = qstrUrl.remove( 0, 7 + qstrHost.length() );// 7 == http://   
		
	return true;
}

??? what mean?

[wysota]

What do you intend to do with those numbers? Because if you want to send them a message "hey, buy our great software", then that's spamming.

[jacek]

Please, don't start more than one thread on the same problem. Threads merged.

[wysota]

This doesn't answer my question.
