网站返回的IdHTTP1.Response.RawHeaders.Text是utf8编码的，之前使用的是D7，读取到的值里面含有中文能正常解码，但是现在换成了XE10.2了，就不知道应该如何转换了，求教

之前：D7 indy superjson
现在：XE10.2 indy superjson


我测试代码为下载一个文件，此文件名处于返回的http header信息中，文件名含中文，需要得到这个文件名
首先在D7中测试，代码为：
Str:=BDC.SysSite 'download/product';
jo := SO('{"productid":"' productid '","type":"' TypeName '"}');
TStream := TMemoryStream.Create;
TJ := TStringList.Create;
TJ.Append(utf8Encode(jo.AsString));
IdHTTP1.Post(Str,TJ,TStream);
TJ.Free;
ProcessTxt.Lines.Add(UTF8Decode(IdHTTP1.Response.RawHeaders.Text));
返回的头部信息为

==========获取成功，得到文件名==========
==========
接下来在10.2的IDE里，代码
jo:=SO();
jo.S['productid']:=productid;
jo.S['type']:=dltypeTxt.Value;
MS := TMemoryStream.Create;
stream := TStringStream.Create(jo.AsString, TEncoding.UTF8);
FWSInfo.IdHTTP1.Post( BDC.SysSite 'download/product', stream,MS);
stream.Free;
dllogTxt.Lines.Add(FWSInfo.IdHTTP1.Response.RawHeaders.Text);
返回的头部信息为：

==========获取失败==========
所以中文要如何转换

能麻煩你提供一下你的 server 網址嗎? 我找時間給你寫一個範例測試看看?
