上面是网上找的:

根据项目需要进行修改:

UrlEncode:

 1 CString URLEncode(CString url)
 2 {
 3     std::wstring text = url;
 4 
 5     size_t len = text.length();
 6     std::wstring encoded = L"";
 7     for(size_t i = 0; i < len; i++)
 8     {
 9         wchar_t wch = text.at(i);
10         if ('A' <= wch && wch <= 'Z') {
11             encoded += wch;
12         } else if ('a' <= wch && wch <= 'z') {
13             encoded += wch;
14         } else if ('0' <= wch && wch <= '9') {
15             encoded += wch;
16         } else if (wch == ' ') {
17             encoded += hexenc[wch];
18         } else if (wch == '-' || wch == '_'
19             || wch == '.' || wch == '!'
20             || wch == '~' || wch == '*'
21             || wch == '\'' || wch == '('
22             || wch == ')') {
23                 encoded += hexenc[wch];
24         } else if (wch <= 0x007f) {        // other ASCII
25             encoded += hexenc[wch];
26         } else if (wch <= 0x07FF) {        // non-ASCII <= 0x7FF
27             encoded += hexenc[0xc0 | (wch >> 6)];
28             encoded += hexenc[0x80 | (wch & 0x3F)];
29         } else {                    // 0x7FF < ch <= 0xFFFF

32             encoded += hexenc[0x80 | (wch & 0x3F)];
33         }
34     }
35     return encoded.c_str();

21                         if(sequence-- == 2)
22                             tconwch = tconwch << 6;
