Hi, where can I find an example of how to use TScHttpWebRequest.RequestStream to transmit parameters ?
I'm using Delphi 7.
Thanks

The RequestSteam property gets or sets a stream that is used to write the request data. This property can be only set if SendChunked is set to True and Method is not rmGET or rmHEAD.

If you mean something else, please clarify.

Four months and still no answer to the OP's question
where can I find an example of how to use TScHttpWebRequest.RequestStream
I have read the documentation and find it lacking, particularly in real life examples of use.
I'm also trying to find out how to POST parameters (as content type application/json).
Simply quoting the documentation in response to a question about it isn't very helpful

You can use code like this to show the use of this property:
Code: Select all
var
Request: TScHttpWebRequest;
Response: TScHttpWebResponse;
ResponseStr: string;
Stream: TFileStream;
begin
Request := TScHttpWebRequest.Create(URL);
Stream := TFileStream.Create(FileName, fmOpenRead);
try
Request.Method := rmPut;
Request.ContentType := 'application/pdf';
Request.TransferEncoding := 'binary';
Request.Headers.Add('Content-Disposition', 'form-data; name="FormFile"; filename="Document1.pdf"');
Request.ContentLength := Stream.Size;
Request.SendChunked := True;
Request.RequestStream := Stream;
Response := Request.GetResponse;
ResponseStr := Response.ReadAsString;
Response.Free;
finally
Stream.Free;
Request.Free;
end;
end;
