Idhttp Post 服务器接收不到数据，求原因

[春华-秋实]

小弟往服务器post 编码过的数据，结果服务器接收不到，不知道post的格式哪里不对了，求指点，代码如下
编码函数如下

AnsiString __fastcall URLEncodeT(AnsiString& inStr)
{
        char hex[] = "0123456789ABCDEF";
        AnsiString dst;
       AnsiString src = inStr;
        for (int i = 1; i <= src.Length(); ++i)
    {
    //ShowMessage(IntToStr(i));
    char cc = src[i];
    if(cc == ' ')
    {
     dst += '+';
    }else if(cc >= 'A' && cc <= 'Z'){
     dst += cc;
    }else if(cc >= 'a' && cc <= 'z'){
     dst += cc;
    }else if(cc >= '0' && cc <= '9'){
     dst += cc;
    }else if(cc == '-' || cc == '.' || cc == '!'|| cc == '_' || cc == '~' || cc == '*' || cc == '\'' || cc == '(' || cc == ')' ){
     dst += cc;
    }else{
      char c = static_cast<unsigned char>(src[i]);
           dst += '%';
           dst += hex[c / 16];
           dst += hex[c % 16];
    }
    }
    return dst; 
}

正文如下

Url = "http://172.21.4.138:8080/UnionUpdate/UnionUpdateService";

ClientVersion = "KABW900+_CH.2.02.002";
request = "<?xml version=\"1.0\" encoding=\"utf-8\"?><Request><RequestType>mobileVersion</RequestType><MobileVersionParams><OpType>verifyRom</OpType><ClientVersion>"+ClientVersion+"</ClientVersion><RomSize>12345678</RomSize><UserName></UserName><SystemOuterVersion></SystemOuterVersion><FileType>img</FileType><CustomizationType>cmcc</CustomizationType><Paramater1></Paramater1><Paramater2></Paramater2><Paramater3></Paramater3></MobileVersionParams><OtherParams></OtherParams></Request>";

AnsiString sa = URLEncodeT(request);

TStringList *params = new TStringList();
AnsiString param = "param";
params->Add((param+"="+sa));
TStringStream *returnString=new TStringStream("");
try
{
IdHTTP1->Post(Url,params,returnString);
}
catch(...)
{
        ShowMessage("服务器连接错误，无法检测升级包的合法性!");
}
delete params;
delete returnString;

搜了下，看到不是dephi的就是pascal的，你专栏里的那个我没看懂，我这个code里哪里错了，能指出来吗？谢谢了~
