curl 获取信息编码问题

[Smile_Tiger]

c++ 利用 curl sdk 获取信息，代码如下：

std::string get(const std::string& strURL)  
{  
    memset(szbuffer,0x0,sizeof(szbuffer));  
    CURL *pCurl = NULL;  
    pCurl = curl_easy_init();   
    if(pCurl == NULL)     
    {  
        //Print Error Info    
    }  
    
    //这是网上的处理方法，但是运行会crash
    //curl_easy_setopt(pCurl,CURLOPT_HTTPHEADER,"content-type: application/x-www-form-urlencoded;charset=UTF-8");
    
   //这是网上的另外一个处理方法，不报错，但是无效
    curl_slist *plist = curl_slist_append(NULL, "Content-Type: application/x-www-form-urlencoded; charset=gb2312");

    curl_easy_setopt(pCurl, CURLOPT_HTTPHEADER, plist);

    curl_easy_setopt(pCurl, CURLOPT_SSL_VERIFYPEER, FALSE);
    curl_easy_setopt(pCurl, CURLOPT_SSL_VERIFYHOST,  FALSE);
    curl_easy_setopt(pCurl, CURLOPT_ERRORBUFFER, szErrorBuffer);  
    curl_easy_setopt(pCurl, CURLOPT_TIMEOUT, 30000);  
    curl_easy_setopt(pCurl, CURLOPT_URL, strURL.c_str());   
    curl_easy_setopt(pCurl, CURLOPT_WRITEFUNCTION, &DownloadData);   
    curl_easy_setopt(pCurl, CURLOPT_WRITEDATA, szbuffer);   
    curl_easy_setopt(pCurl, CURLOPT_HEADER, 0);  

    CURLcode code = curl_easy_perform(pCurl);  
    if(code != CURLE_OK)  
    {  
        //curl_easy_perform failed    
    }  

    if (pCurl)   
    {   
        curl_easy_cleanup(pCurl);   
        pCurl = NULL;   
    }  
    return szbuffer;  
}  

测试代码:

        std::string path;
        path =  "http://192.168.1.107:8080/query/user/info.html?param=test";
        std::string strRet = get(path.c_str());  

浏览器中的结果： "{\"date\":\"\",\"errorMsg\":\"json串为空\",\"map\":null,\"reqTime\":0,\"result\":1}"
c++运行的结果：" {\"date\":\"\",\"errorMsg\":\"json涓蹭负绌篭",\"map\":null,\"reqTime\":0,\"result\":1}"

该怎样正确处理编码？

已经解决！

//gbk ת utf8
std::string GBKToUTF8(const std::string& strGBK)
{
    std::string strOutUTF8 = "";
    WCHAR * str1;
    int n = MultiByteToWideChar(CP_ACP, 0, strGBK.c_str(), -1, NULL, 0);
    str1 = new WCHAR[n];
    MultiByteToWideChar(CP_ACP, 0, strGBK.c_str(), -1, str1, n);
    n = WideCharToMultiByte(CP_UTF8, 0, str1, -1, NULL, 0, NULL, NULL);
    char * str2 = new char[n];
    WideCharToMultiByte(CP_UTF8, 0, str1, -1, str2, n, NULL, NULL);
    strOutUTF8 = str2;
    delete[]str1;
    str1 = NULL;
    delete[]str2;
    str2 = NULL;
    return strOutUTF8;
}

//utf-8 ת gbk
std::string UTF8ToGBK(const std::string& strUTF8)
{
    int len = MultiByteToWideChar(CP_UTF8, 0, strUTF8.c_str(), -1, NULL, 0);
    unsigned short * wszGBK = new unsigned short[len + 1];
    memset(wszGBK, 0, len * 2 + 2);
    MultiByteToWideChar(CP_UTF8, 0, (LPCSTR)strUTF8.c_str(), -1, (LPWSTR)wszGBK, len);

    len = WideCharToMultiByte(CP_ACP, 0, (LPWSTR)wszGBK, -1, NULL, 0, NULL, NULL);
    char *szGBK = new char[len + 1];
    memset(szGBK, 0, len + 1);
    WideCharToMultiByte(CP_ACP,0, (LPWSTR)wszGBK, -1, (LPSTR)szGBK, len, NULL, NULL);
    //strUTF8 = szGBK;
    std::string strTemp(szGBK);
    delete[]szGBK;
    delete[]wszGBK;
    return strTemp;
