Thread: using ifsteam from a webpage??

To the best of my knowledge, no one has written a TCP, HTTP, or any other kind of internet stream and made it publically available.

No, the iostream interface is too unflexible for any serious net communication to be done over it.

if i post this link you can see what information i need from the web site

but where it says zezima u will be able to put any name you want but im sure ill work that out just need to get that info



http://hiscore.runescape.com/lang/en/aff/runescape/hiscorepersonal.ws?user1=zezima

this has the info i need for my program im sure ill be able to parse the data t omy program but i would have no idea how to make that class work?

twomers if u could maybe point me in the right direction or give me a link to where i can find out how to get the webpage to download to my program i would appreciate it very much

and again thank you

Sure I'll go one better, here's some source:

Code:

#include <iostream>
#include <string>
#include <fstream>

#include <urlmon.h>

#pragma comment( lib, "urlmon.lib" )	

class URLstream 
{

private:
	std::string PageURL;
	std::string PageSource;

	HRESULT ReturnValue;

	void ReadFile ( void );


public:
	URLstream( void );
	URLstream( std::string n_PageURL );

	bool open( std::string n_PageURL );

	void getpage( void );

	friend std::istream &operator >> ( std::istream &in,  URLstream &instance );
	friend std::ostream &operator << ( std::ostream &out, URLstream &instance );

};

void URLstream::ReadFile( void )
{
	std::ifstream in ( "tmp.tmp" );
	std::string tmp;

	if ( in )
		while ( std::getline( in, tmp ) )
			PageSource += tmp + "\n";

	in.close();
}

URLstream::URLstream( void ) : ReturnValue( 0 ) 
{}

URLstream::URLstream( std::string n_PageURL ) : PageURL( n_PageURL ), ReturnValue( 0 )
{
	open( PageURL );
}

bool URLstream::open( std::string n_PageURL )
{
	PageURL = n_PageURL;

	ReturnValue = URLDownloadToFile( NULL, PageURL.c_str(), "tmp.tmp", 0, NULL );

	if ( ReturnValue == E_OUTOFMEMORY )
		return false;

	ReadFile();

	return true;
}

std::istream &operator >> ( std::istream &in, URLstream &instance )
{
	in >> instance.PageURL;
	instance.open( instance.PageURL );

	return in;
}

std::ostream &operator << ( std::ostream &out, URLstream &instance )
{
	return out << instance.PageSource;
}

int main( void )
{
	URLstream URL;

	std::cout<< "Enter the URL: ";
	std::cin >> URL;
	std::cout<< URL;


	return 0;
}

You're gonna have to wait for the file to download properly though.

EDIT: You're probably going to have to put in the whole address. with the http:// etc. The checking I put in there was minimal so you should put in more, and more functions too.

hey thanks alot i really appreciate it.
at a quick glance i thinks its gone straight over my head but ill read through and study it properly. im sure that is just what i need


thank you

ok the first thing i dont understand is the <urlmon>
and the urlmon.lib
are these files included with my compiler? i use devcpp 4.9.8.0

sorry i ment the code you wrote for me didnt compile when i saved it as url.cpp
but it did compile when i saved it as url.h

i just googled urlmon.h but i couldnt find any place to download it from have you got any ideas where i could find it?
