需要将返回的UTF-8数据转换为string，char等都支持的ansi

void ConvertUTF8ToANSI(CString strUTF8,CString &strANSI) //   {   	int nLen = ::MultiByteToWideChar(CP_UTF8, MB_ERR_INVALID_CHARS, (LPCTSTR)strUTF8, -1, NULL, 0); 	//返回需要的unicode长度   	WCHAR *wszANSI = new WCHAR[nLen+1];   	memset(wszANSI, 0, nLen * 2 + 2);   	nLen = MultiByteToWideChar(CP_UTF8, 0, (LPCTSTR)strUTF8, -1, wszANSI, nLen);    //把utf8转成unicode  	nLen = WideCharToMultiByte(CP_ACP, 0, wszANSI, -1, NULL, 0, NULL, NULL);        //得到要的ansi长度   	char *szANSI=new char[nLen + 1];   	memset(szANSI, 0, nLen + 1);   	WideCharToMultiByte (CP_ACP, 0, wszANSI, -1, szANSI, nLen, NULL,NULL);          //把unicode转成ansi   	strANSI = szANSI;   	delete wszANSI;   	delete szANSI;   }

或者利用C++11

void ConvertUTF8ToANSI(){   	auto LocUtf8 = std::locale(std::locale(""), new std::codecvt_utf8
   
    );	std::wifstream wfin("temp1.xml");	std::wstring wstr, content;	wfin.imbue(LocUtf8);	while(getline(wfin, wstr))	{		content += wstr;	}	wfin.close();	system("del temp1.xml");	//std::wcout.imbue(std::locale(""));	//std::wcout << content << std::endl;	std::locale::global(std::locale("Chinese-simplified"));	std::wofstream wfout("temp.xml");	wfout << content;	wfout.close();}

寻得一个不用解码的API

支持的常用的快递公司更多，果断换了。
