Re: RE: [qDecoder] 버그인지는 모르겠지만….

qURLencode가 아니라 qURLdecode 였어요. 죄송합니다..
아무튼 문제가 있긴 해요..
결과가 아래와 같이 나옵니다.

query_string이 sss="%2000%" 일경우…

sss = " 00?

이렇게 나오고요……

query_string이 sss=%22+00%25%22 이면

sss = " 00%"

이렇게 나옵니다..

이 문제에 대해서 알수 있는 url 알려드리겠습니다..

http://www.blooberry.com/indexdot/html/topics/urlencoding.htm

그리고.. 제가 해결했긴 했는데 제대로 했는지 모르겠습니다..

/* Heximal 코드 이면 1 아니면 0을 리턴 */
int isHex(char c)
{
   if((c >= ‘0’) && (c <= ‘9’)) return 1;
   else if((c >= ‘A’) && (c <= ‘Z’)) return 1;
   else if((c >= ‘a’) && (c <= ‘z’)) return 1;
   else return 0;
}

/**********************************************
** Usage : qURLdecode(Query Pointer);
** Return: Pointer of Query string
** Do    : Decode query string
**********************************************/
void qURLdecode(char *str){
int i, j;

if(!str)return;
for(i = j = 0; str[j]; i++, j++){
   switch(str[j]){
     case ‘+’:{
       str[i] = ‘ ‘;
       break;
     }
     case ‘%’:{
if (!str[j+1]) break;
/* ‘%’ 뒤에 오는 문자가 Heximal 인지 판단 */
if (!isHex(str[j+1]))
{
str[i] = str[j];
break;
}

       str[i] = _x2c(str[j + 1], str[j + 2]);
       j += 2;
       break;
     }
     default:{
       str[i] = str[j];
       break;
     }
   }
}
str[i]=’’;
}
