TsgcHTTP2Client | HTTP/2 Download File

When the client requests a file from the server, use OnHTTP2Response event to load the stream response.

 

Large File Downloads

When downloading large files (hundreds of MB or more), set HTTP2Options.ReadTimeout to 0 (no timeout) to ensure the transfer completes without being interrupted by the default 60-second timeout:

 

oClient := TsgcHTTP2Client.Create(nil);
oClient.HTTP2Options.ReadTimeout := 0; // no timeout for large files
oClient.Get('https://server/largefile', oStream);

 

oClient := TsgcHTTP2Client.Create(nil);
oClient.OnHTTP2Response := OnHTTP2ResponseEvent;
oClient.Get('https://http2.golang.org/file/gopher.png');
...
procedure OnHTTP2ResponseEventEvent(Sender: TObject; const Connection: TsgcHTTP2ConnectionClient; 
  const Request: TsgcHTTP2RequestProperty; const Response: TsgcHTTP2ResponseProperty)
begin
  oStream := TFileStream.Create('file', fmOpenWrite or fmCreate);
  Try
    oStream.CopyFrom(Response.Data, Response.Data.Size);
  Finally
    oStream.Free;
  End;
end;
