Re: Sockets and webservers

Yeah, get the server uptime, then save it to sql, then make a simple .php script to get it on webpage.

Re: Sockets and webservers

Of course.

You can find a way to get the uptime here:

and you can create a webserver with:

Re: Sockets and webservers

My clan runs this on all their servers

Code:

#include <amxmodx>

#include <fakemeta>



new amx_gamename;

public plugin_init( ) { 

        register_plugin( "Game Namer", "1.1", "NeuroToxin" ); 

        amx_gamename = register_cvar( "amx_gamename", "Team Fortress Classic" ); 

        register_forward( FM_GetGameDescription, "GameDesc" ); 

}

 

public GameDesc( ) { 

        static gamename[32]; 

        get_pcvar_string( amx_gamename, gamename, 31 ); 

        forward_return( FMV_STRING, gamename ); 

        return FMRES_SUPERCEDE; 

}

Sometimes we change domains or forums, is their a way to make this plugin retrieve the value of amx_gamename from a web page?

Re: Sockets and webservers

Great Tutorial :D ! But how to use sockets with an IRC-Bot ???

Re: Sockets and webservers

hallo,

i try to compile the example but i'm getting alot of errors:

any ideas to get it working?

Re: Sockets and webservers

download it locally and not with the webcompiler

Re: Sockets and webservers

it's not the web compiler, it's the "else" in connect_web() having its closing bracket missing.

EDIT:
oh, and the closing bracket for if (socket_change(g_sckweb, 100)) is missing also. and an include for <amxmodx> before the <sockets> include is needed as well. let me just post the code that compiles:

Code:

#include <amxmodx>
#include <sockets>

new g_sckweb //socket "id"

#define SCRIPT_NAME "/myplugin/parser.php"
#define REMOTE_HOST "myserver.com" //port d.80

public plugin_init()
{
    register_plugin("Socket sample", "??" ,"Darksnow")
    set_task(5.0,"connect_web") 
}

public connect_web()
{
    new error = 0
    new constring[512]

    g_sckweb = socket_open(REMOTE_HOST, 80, SOCKET_TCP, error)
    if (g_sckweb > 0)
    {
        format(constring,511,"GET %s HTTP/1.1^nHost: %s^n^n",SCRIPT_NAME,REMOTE_HOST)
        write_web(constring)
        read_web()
    }
    else
    {
        switch (error)
        {
            case 1: { server_print("Error creating socket"); }
            case 2: { server_print("Error resolving remote hostname"); }
            case 3: { server_print("Error connecting socket"); }
        }
    }
    return PLUGIN_CONTINUE
}

public read_web()
{
    const SIZE = 63
    new line_variable[SIZE + 1], line_value[SIZE + 1]

    if (socket_change(g_sckweb, 100))
    {
        new buf[512], lines[30][100], count = 0
        socket_recv(g_sckweb, buf, 511)
        count = ExplodeString(lines, 50, 119, buf, 13)
        for(new i=0;i<count;i++)
        {
            parse(lines[i], line_variable, SIZE, line_value, SIZE)
            if (equal(line_variable, "some_value"))
            {
                server_print("Value is %s", line_value)
            }
        }   
    }

    if (g_sckweb != 0)
        set_task(0.5, "read_web")
    else
        disconnect_web()
}

public write_web(text[512])
{
    socket_send(g_sckweb, text, 511)
}

public disconnect_web()
{
    server_print("Socket disconnected")
}

stock ExplodeString( p_szOutput[][], p_nMax, p_nSize, p_szInput[], p_szDelimiter ) { // Function by xeroblood
    new nIdx = 0, l = strlen(p_szInput)
    new nLen = (1 + copyc( p_szOutput[nIdx], p_nSize, p_szInput, p_szDelimiter ))
    while( (nLen < l) && (++nIdx < p_nMax) )
        nLen += (1 + copyc( p_szOutput[nIdx], p_nSize, p_szInput[nLen], p_szDelimiter ))
    return nIdx
}

Re: Sockets and webservers

One question about the first sockets sample.

Why don't we need to call socket_close ?

Re: Sockets and webservers

Can someone please give a working example about how to retrive some data from a .php file using sockets?
