Want for urldecode method, need help with rewrite from C

Code:

https://github.com/abejfehr/URLDecode/blob/master/urldecode.c

Need help in written same code in SM. Thx. I use sockets which not provided UTF-8 decoding

Re: Want for urldecode method, need help with rewrite from C

I've something like this.. that all which can I do ))

Code:

stock void decodeURL(const char[] inStr, char[] outStr, int size) {
    
    char buffer[4096]; int len = strlen(inStr); int wpos = 0; int diff = 0;
    
    // "%D0%BF%D1%80%D0%BE%D1%81%D1%82%D0%BE+%D0%BF%D0%B0%D1%80%D0%B0%D0%BB%D0%BB%D0%B5%D0%BB%D1%8C%D0%BD%D1%8B%D0%B9+%D0%BC%D0%B8%D1%80" = len
    
    for(int i = 0; i < len; i += diff)
    {
        special[4]; strcopy(special, sizeof(special), inStr[i]);
        chars[6]; strcopy(chars, sizeof(chars), inStr[i]);
    
        for(int j = 0; j < sizeof(dec); ++j)
        {
            if(StrEqual(special, dec[j][1], false))
            {
                strcopy(outStr, size, inStr[wpos]); ++wpos; diff = 4;
            }
            
            else if(StrEqual(chars, dec[j][1], false))
            {
                strcopy(outStr, size, inStr[wpos]); ++wpos;  diff = 6;
            }
        }
    }
    
    PrintToServer("Decoded URL: %s", outStr);
}

And some characters table..

Code:

static char dec[][] = {
    {"~", "%7E"},
    {"`", "60%"},
    {"'", "27%"},
    
    /* ....... */

    {"Ю", "%D0%A%"},
    {"ю", "%D1%8%"},
    {"Я", "%D0%A%"},
    {"я", "%D1%8F"}
};

Re: Want for urldecode method, need help with rewrite from C

....I don't know.
I maybe made it too complex. Have a fun.

resultss

Code:

char buffer[] = "https%3A%2F%2Fwww.google.ca%2F%3Fgws_rd%3Dssl%23q%3Durl%2Bdecoding";

PrintToServer "httpsAFFwww.google.caFFgws_rdDsslqDurlBdecoding"

PrintToServer "https://www.google.ca/?gws_rd=ssl#q=url+decoding"

PHP Code:


		
			
#include <regex>



Regex regex;



public void OnPluginStart()

{

    regex = new Regex("^%[0-9a-fA-F]{2}");



    if(regex == null) SetFailState("Regex fail");



    RegConsoleCmd("sm_test", test);



}



public Action test(int client, int args)

{



    char buffer[] = "https%3A%2F%2Fwww.google.ca%2F%3Fgws_rd%3Dssl%23q%3Durl%2Bdecoding";



    char buffer2[PLATFORM_MAX_PATH];



    PrintToServer(buffer); // ...you not see '%' symbols in console, function is formatting it.



    int index = 0;

    int result;





    do

    {



        result = FindCharInString(buffer[index], '%', false);



        if(result == -1) break;



        index += result;



        //PrintToServer("%s", buffer[index]);





        // found something like %3A

        if(isxdigit(buffer[index]))

        {

            // Change characters to hex value

            char a[4]; // %3A

            char b[2]; // new character



            Format(a, sizeof(a), "%c%c%c", buffer[index], buffer[index+1], buffer[index+2]);



            Format(b, sizeof(b), "%c", StringToInt(a[1], 16)); // exclude %



            //PrintToServer("%s", b);



            ReplaceString(buffer, sizeof(buffer), a, b, true);

            

            index = -1; // reset loop



        }







        index++;



    }

    while( index < strlen(buffer))

    



    // Final

    PrintToServer("%s", buffer);



}





bool isxdigit(const char[] x)

{

    char a[4]; // %3A

    Format(a, sizeof(a), "%c%c%c", x[0], x[1], x[2]);



    //PrintToServer("%s", a);



    return regex.Match(a) > 0;

}

Re: Want for urldecode method, need help with rewrite from C

Code:

PrintToServer(buffer); // ...you not see '%' symbols in console, function is formatting it.

This is dangerous, the correct usage is:

Code:

PrintToServer("%s", buffer);

Re: Want for urldecode method, need help with rewrite from C

I'm late but there are 2 natives provided by System2 Extension.

Code:

/**

 * Converts a plain string to an URL encoded string.

 * All input characters that are not a-z, A-Z, 0-9, '-', '.', '_' or '~' 

 * are converted to their "URL escaped" version (%NN where NN is a two-digit hexadecimal number).

 *

 * Be aware that the output string may be larger then the input string.

 *

 * @param output        Buffer to store encoded string in. May point to the input string (will replace the input string).

 * @param maxlength     Maxlength of the output buffer.

 * @param input         String to encode.

 * @param ...           Input string format arguments

 *

 * @return              True on success, false otherwise.

 */

native bool System2_URLEncode(char[] output, int maxlength, const char[] input, any ...);



/**

 * Converts an URL encoded string to a plain string.

 * All input characters that are URL encoded (%XX where XX is a two-digit hexadecimal number) are converted to their binary versions.

 *

 * @param output        Buffer to store decoded string in. May point to the input string (will replace the input string).

 * @param maxlength     Maxlength of the output buffer.

 * @param input         String to decode.

 * @param ...           Input string format arguments

 *

 * @return              True on success, false otherwise.

native bool System2_URLDecode(char[] output, int maxlength, const char[] input, any ...);
