一、提交参数为json格式,返回数据也为json格式

TStringStream * ms;
char * lpBuf;
TStringList * pParam;
try
{
  //http路径
  AnsiString g_Url= m_httpPath+"Basic/SJG/CheckLogin";
  //接收返回值
  ms     = new  TStringStream("");
  //参数,json格式
  pParam = new  TStringList();
  pParam->Add("{\"LoginName\":20120701,");
  pParam->Add("\"LoginPsw\":\"x12jTF5\",");
  pParam->Add("\"GEID\":20120701}");

  idhtpXR->Request->ContentType    = "application/json";
  idhtpXR->Request->AcceptEncoding = "gzip,deflate,br";
  idhtpXR->Post(g_Url,pParam,ms); //Post提交

  mmoInfo->Text = ms->DataString;//返回为json格式
}
__finally
{
  delete ms;
  delete pParam;
}

二、参数中带Token的post提交如下:

bool  TXingRuan::HeartBeat()
{
    TStringStream * ms     = new  TStringStream("");
    TStringStream * pParam = new  TStringStream("1");

    AnsiString strUrl= m_strPublicPath+"Basic/SJG/HeartBeat";

   try
   {
	  m_pIdHttp->Request->ExtraHeaders->Values["Token"]=Token;//添加Token
      m_pIdHttp->Request->ContentLength = pParam->DataString.Length();//不能为0
      m_pIdHttp->Post(strUrl,pParam,ms);
	  neb::CJsonObject oJson ( ms->DataString.c_str() );
      std::string info = oJson("info");
      m_strInfo  = m_Http.UTF8_To_string(info).c_str();
	  delete ms;
	  delete pParam;
      return true;
   }
   catch(...)
   {
	  delete ms;
	  delete pParam;
      return false;
   }
}

如果参数中包含中文,在用json传输参数时,需要先使用URLEncode编码,否则出现:"400 bad request" 错误提示
pParam->WriteString(URLEncode("\"BsName\":\""+BsName+"\","));//GB2312编码
如果是utf-8编码方式,需要将输入的json字符串,转成unicode码。
