前端传过来的中文参数是%3D%E9%98%BF%E8%90%A8%E8%BE%BE%26,需要将这个参数转换为中文
#include "stdafx.h"
#include <iostream>
#include < codecvt>
#include <locale>
std::string unicodeToString(const std::string &str) {
std::string u8str ;
std::wstring_convert<std::codecvt_utf8<char32_t>, char32_t> converter;
for (size_t i = 0; i < str.length(); ) {
char32_t uhan = strtol(str.substr(i,4).c_str(), nullptr, 16);
u8str += converter.to_bytes (uhan);
i+=4;
}
return u8str;
}
int main() {
std::cout << unicodeToString( "4F 60597D554A" ) << std::endl ;
return 0;
}
在网上试了好多方法,要么是代码报错,要么就是解析出来的是乱码
#include <stdio.h>
#include <string.h>
#include <windows.h>
int main() {
char s[]="%3D%E9%98%BF%E8%90%A8%E8%BE%BE%26";
char msg[256];
char b[256];
WCHAR wstr[256];
int i,L;
i=0;
while (1) {
if (1!=sscanf(s+i*3,"%%%02X",&L)) break;
msg[i]=(char)L;
i++;
if (i>=256-1) break;
}
msg[i]=0;
L=strlen(msg);
i=MultiByteToWideChar(CP_UTF8,0,msg,L,wstr,256);
wstr[i] = 0;
i=WideCharToMultiByte(CP_OEMCP,WC_COMPOSITECHECK,wstr,i,b,256,0,0);
b[i]=0;
printf("[%s]\n",b);//[=阿萨达&]
return 0;
}
试试这个

decodeURIComponent('%3D%E9%98%BF%E8%90%A8%E8%BE%BE%26')
'=阿萨达&'
c++ 应该也有现在库吧 decodeURI 类似的搜索一下
楼上的C实现已经相当高效了,我续个C++版本的
