回覆： Re: [twsocket] HTTP POST - SendStream With TMemoryStream

[Opqrst Ghrst]

hello

I try to use FileStrem, it must has Free Space to
create the same size of File,but it should be better
than TmemoryStream, if teh file is biger.

HttpCli-ContentTypePost=multipart/form-data;
boundary=---7d5168231620eb2;
Buf1=-7d5168231620eb2\r\nContent-Disposition:
form-data; name=fname+;
filename=+key+\r\nContent-Type:
application/octet-stream\r\n\r\n;
Buf2==-7d5168231620eb2--

SendStream=new TFileStream(temp, fmCreate);
SendStream-Size=0;
SendStream-WriteBuffer(Buf1.c_str(), Buf1.Length());
TFileStream* ms=new
TFileStream(Filepath.c_str(), fmOpenRead);
SendStream-CopyFrom(ms,ms-Size);
delete ms;
SendStream-WriteBuffer(Buf2.c_str(), Buf2.Length());
SendStream-Seek(0, soFromBeginning);

 You should use a TFileStream instead of a
 TMemorystream.

 Subject: [twsocket] HTTP POST - SendStream With
 TMemoryStream
 
 
 
  Hello all,
 
  when I use Http Post Web to send file,
  if the file is bigger as 100mb.
  because content must has some FormField to post,
  I use MemorrStream write these information and
  FileStream.
  when I load to TMemoryStream it will cause my
 computer
  slow to build MemoryStream, can I use other
 mothods to
  resolve this problem?

thanks F.P.

I See,
but if the file is more than 1 GB, That will cost my
too mush disk free space,I am confuse on this problem,
because I must add Form Field Value information on the
Head of the data and boundary end of data.it will be
work by ContentTypePost=multipart/form-data mothod
post.

 If you use TMemoryStream, then your 100MB of data is
 loaded onto RAM which 
 can be slow. Use another kind of TStream, for
 example a TFileStream which 
 store his data in a disk file instead of RAM.
