gsoap 中文亂碼問題

中文亂碼與locale有關，這裡給出兩種解決方法：

一、設定locale

      1、setlocale(LC_ALL, "");//設定程式locale為系統預設（我的系統是zh_CN.utf8），gsoap内部進行編碼轉換依賴于locale,是以必須設定為中文環境。

      2、gSoap初始化 gSoap生成的代理類名字為：CSmsProxy

           CSmsProxy soapRequest(SOAP_C_MBSTRING);

      下面同一般程式設計。gSoap會自動把字元串轉換為正确的編碼。

二、不設定locale，使用預設的"C" locale，程式中傳給gSoap、從gSoap接收的字元串都使用utf8編碼

      代理類初始化： CSmsProxy soapRequest(SOAP_C_UTFSTRING);

      下面同一般程式設計。gSoap會把字元串當成utf8編碼處理。

下面附帶gb2312與utf8編碼之間的轉換函數：

//gb2312轉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轉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轉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轉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轉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");
