gsoap 中文乱码问题

中文乱码与locale有关，这里给出两种解决方法：

一、设置locale

      1、setlocale(LC_ALL, "");//设置程序locale为系统默认（我的系统是zh_CN.utf8），gsoap内部进行编码转换依赖于locale,所以必须设置为中文环境。

      2、gSoap初始化 gSoap生成的代理类名字为：CSmsProxy

           CSmsProxy soapRequest(SOAP_C_MBSTRING);

      下面同一般编程。gSoap会自动把字符串转换为正确的编码。

二、不设置locale，使用默认的"C" locale，程序中传给gSoap、从gSoap接收的字符串都使用utf8编码

      代理类初始化： CSmsProxy soapRequest(SOAP_C_UTFSTRING);

      下面同一般编程。gSoap会把字符串当成utf8编码处理。

下面附带gb2312与utf8编码之间的转换函数：

//gb2312转utf8 

void Gb2312ToUtf8(char* pstrOut, u32 dwOutLen, const char* pstrIn, u32 dwInLen) 

{ 

#ifdef WIN32 

    int i = MultiByteToWideChar(CP_ACP, 0, pstrIn, -1, NULL, 0); 

    wchar_t * strSrc = new wchar_t[i+1]; 

    MultiByteToWideChar(CP_ACP, 0, pstrIn, -1, strSrc, i); 

    i = WideCharToMultiByte(CP_UTF8, 0, strSrc, -1, NULL, 0, NULL, NULL); 

    if (i >= dwOutLen) 

    { 

        i = dwOutLen - 1; 

    } 

    WideCharToMultiByte(CP_UTF8, 0, strSrc, -1, pstrOut, i, NULL, NULL); 

    delete strSrc; 

#else 

    iconv_t iConv = iconv_open("utf-8", "gb2312"); 

    iconv(iConv, (char **)&pstrIn, (size_t *)&dwInLen, (char **)&pstrOut, (size_t *)&dwOutLen); 

    iconv_close(iConv); 

#endif 

} 

//utf8转gb2312 

void Utf8ToGb2312(char* pstrOut, u32 dwOutLen, const char* pstrIn, u32 dwInLen) 

    if (NULL == pstrOut) 

        return ; 

    int i = MultiByteToWideChar(CP_UTF8, 0, pstrIn, -1, NULL, 0); 

    MultiByteToWideChar(CP_UTF8, 0, pstrIn, -1, strSrc, i); 

    i = WideCharToMultiByte(CP_ACP, 0, strSrc, -1, NULL, 0, NULL, NULL); 

    WideCharToMultiByte(CP_ACP, 0, strSrc, -1, pstrOut, i, NULL, NULL); 

    iconv_t iConv = iconv_open("gb2312", "utf-8"); 

}

//gb2312转Unicode 

void Gb2312ToUnicode(wchar_t* pstrOut, u32 dwOutLen, const char* pstrIn, u32 dwInLen) 

    u32 i = MultiByteToWideChar(CP_ACP, 0, pstrIn, -1, NULL, 0); 

    MultiByteToWideChar(CP_ACP, 0, pstrIn, -1, pstrOut, i); 

    iconv_t iConv = iconv_open("unicode", "gb2312"); 

    iconv(iConv, (char**)pstrIn, &dwInLen, (char**)pstrOut, &dwOutLen); 

//Unicode转Gb2312 

void UnicodeToGb2312(char* pstrOut, u32 dwOutLen, const wchar_t* pstrIn, u32 dwInLen) 

    u32 i = WideCharToMultiByte(CP_ACP, 0, pstrIn, -1, NULL, 0, NULL, NULL); 

    WideCharToMultiByte(CP_ACP, 0, pstrIn, -1, pstrOut, i, 0, 0); 

    iconv_t iConv = iconv_open("gb2312", "unicode"); 

//utf8转Unicode 

void Utf8ToUnicode(wchar_t* pstrOut, u32 dwOutLen, const char* pstrIn, u32 dwInLen) 

    u32 i = MultiByteToWideChar(CP_UTF8, 0, pstrIn, -1, NULL, 0); 

    MultiByteToWideChar(CP_UTF8, 0, pstrIn, -1, pstrOut, i); 

    iconv_t iConv = iconv_open("unicode", "utf-8");
