上面是网上找的:
根据项目需要进行修改:
UrlEncode:
CString URLEncode(CString url)
{
std::wstring text = url; size_t len = text.length();
std::wstring encoded = L"";
for(size_t i = ; i < len; i++)
{
wchar_t wch = text.at(i);
if ('A' <= wch && wch <= 'Z') {
encoded += wch;
} else if ('a' <= wch && wch <= 'z') {
encoded += wch;
} else if ('' <= wch && wch <= '') {
encoded += wch;
} else if (wch == ' ') {
encoded += hexenc[wch];
} else if (wch == '-' || wch == '_'
|| wch == '.' || wch == '!'
|| wch == '~' || wch == '*'
|| wch == '\'' || wch == '('
|| wch == ')') {
encoded += hexenc[wch];
} else if (wch <= 0x007f) { // other ASCII
encoded += hexenc[wch];
} else if (wch <= 0x07FF) { // non-ASCII <= 0x7FF
encoded += hexenc[0xc0 | (wch >> )];
encoded += hexenc[0x80 | (wch & 0x3F)];
} else { // 0x7FF < ch <= 0xFFFF
encoded += hexenc[0xe0 | (wch >> )];
encoded += hexenc[0x80 | ((wch >> ) & 0x3F)];
encoded += hexenc[0x80 | (wch & 0x3F)];
}
}
return encoded.c_str();
}
UrlDecode：
CString UrlDecode(CString encodeUrl)
{
std::wstring text = encodeUrl;
std::wstring decoded = L"";
wchar_t temp[] = L"0x00";
size_t len = text.length();
int sequence = ;
wchar_t conwch = ;
for(size_t i = ; i < len; i++)
{
wchar_t wch = text.at(i++);
if((wch == '%') && (i+ < len))
{
temp[] = text.at(i++);
temp[] = text.at(i);
long tconwch = wcstol(temp, NULL, );
if(tconwch <= 0x7F) {
decoded += tconwch; // normal ascii char
} else if(tconwch >= 0x80 && tconwch <= 0xBF) { // partial byte
tconwch = tconwch & 0x3F;
if(sequence-- == )
tconwch = tconwch << ;
conwch |= tconwch;
if(sequence == )
decoded += conwch;
} else if(tconwch >= 0xC0 && tconwch <= 0xDF) {
conwch = (tconwch & 0x1F) << ; // make space for partial bytes
sequence = ; // 1 more partial bytes follow
} else if(tconwch >= 0xE0 && tconwch <= 0xEF) {
conwch = (tconwch & 0xF) << ; // make space for partial bytes
sequence = ; // 2 more partial bytes follow
} // TODO add case fore 3 partial bytes ... very rare
} else {
decoded += text.at(--i);
}
}
return decoded.c_str();
}
