How to get data from page an independent of your size?


In:

PHP Code:

    new g_Socket, g_Data[2000], sendbuffer[512]
    g_Socket = socket_open("127.0.0.1", 80, SOCKET_TCP, error)
    format(sendbuffer, 1024, "GET /data.php HTTP/1.1^nHost: 127.0.0.1^n^n")
    socket_send(g_Socket, sendbuffer, 1024)
    
    if (socket_change(g_Socket))
    {
        socket_recv(g_Socket, g_Data, 999)
        server_print("Data: %s", g_Data)
    }
    socket_close(g_Socket) 


Is not picking up all the page content, why?

Socket has a limit? I can not solve this problem ...

[jimaway]

socket_recv(g_Socket, g_Data, 999)

there's your limit, you read 999 bytes of data (and for some bizarre reason you declare the g_Data array with 2000 cells)

My data.php page:

PHP Code:

<?php
header('Content-Type: application/json');
?>
{"hats":[{"id":"1","name":"Meu Hats","arquivo":"hat.mdl"},{"id":"2","name":"Meu Hat 2","arquivo":"hat2.mdl"}],"hats":"2"}

server_print("Data: %s", g_Data) return only:

Json: HTTP/1.1 200 OK
Date: Sun, 18 Jan 2015 00:27:14 GMT
Server: Apache/2.4.10 <Win32> OpenSSL/1.0.1i PHP/5.6.3
X-Powered-By: PHP/5.6.3
Content-Length: 122
Content-Type: application/json

{"hats":[{"id":"1","name":"Meu Hats","arquivo":"hat.mdl"},

Why?

It's possible that server_print() will only show up to X characters per print, but I'm not sure on that one.

There are some instances where you will not receive all data in a single socket_recv() call. I quickly put this together to show you how to get an entire file. It will write all received data to TESTFILE.txt in your mod directory.

PHP Code:

#include <amxmodx>
#include <sockets>

new g_Socket;
const TASKID = 5213;

public plugin_init() 
{
    register_concmd( "test" , "test" );
}

public test()
{
    new sendbuffer[512] , error

    g_Socket = socket_open( "www.google.com" , 80 , SOCKET_TCP , error );
    
    if ( g_Socket && !error )
    {
        formatex( sendbuffer , charsmax( sendbuffer ) , "GET /index.html HTTP/1.1^nHost: www.google.com^n^n" );
        socket_send( g_Socket, sendbuffer , sizeof( sendbuffer ) );
        
        //Create a task to check for data every second (you would want a faster interval in real-world situations)
        set_task( 1.0 , "CheckForData" , TASKID , .flags="b" );

        //Create a task to close the socket and stop checking for data after 60 seconds. There are cleaner ways, this 
        //was just a fast method for demonstration.
        set_task( 60.0 , "CloseSocket" );
    }
}

public CheckForData()
{
    static g_Data[2000];
    new iRecv;
    
    server_print("Checking for data")
    
    if ( socket_change( g_Socket ) )
    {
        iRecv = socket_recv(g_Socket, g_Data, charsmax( g_Data ) )
        server_print("Recv=%d Data: %s", iRecv , g_Data)
        write_file( "TESTFILE.txt" , g_Data );
    }
}

public CloseSocket()
{
    socket_close( g_Socket );
    remove_task( TASKID );
}
