I've seen this function on the forum:
Code: [Select]procedure DownloadFile(const Url, PathToSaveTo: string);
var
  fs: TFileStream;
begin
   fs := TFileStream.Create(PathToSaveTo, fmOpenWrite or fmCreate);
   try
      HttpGetBinary(Url, fs);
   finally
      fs.Free;
   end;
end;  
But how to make a POST requiest in it? I want to send a HTML file and
get as result PDF file (my php script can handle it).

Hello,

Know Brook framework (http://brookframework.org), downloading current
version in:
https://github.com/silvioprog/brookframework/archive/master.zip

So, you can do it easily, e.g:

Code: [Select]uses
  BrookHTTPClient, BrookFCLHTTPClientBroker, BrookHTTPConsts;

procedure TForm1.Button1Click(Sender: TObject);
var
  VHttp: TBrookHTTPDef;
  VClient: TBrookHTTPClient;
begin
  VClient := TBrookHTTPClient.Create('fclweb');
  try
    VClient.Prepare(VHttp);
    VHttp.Url := 'your-url';
    VHttp.Method := BROOK_HTTP_REQUEST_METHOD_POST;
    VHttp.Contents.LoadFromFile('your-file.html');
    if VHttp.Request then
      VHttp.Contents.SaveToFile('your-file.pdf')
    else
      ShowMessageFmt('ERROR: code: %d, text: %s, content: %s',
        [VHttp.StatusCode, VHttp.ReasonPhrase, VHttp.Contents.Text]);
  finally
    VHttp.Free;
    VClient.Free;
  end;
end;
Good luck!

Thank you very much but can you tell me how to get the HTML file in
server-side PHP script? I mean, okay, i sent it to server but i don't
know how to work with it. Can you make a simple example for me to show
how to gain file content in PHP server-side script, please?

Hm... I don't know if it would be interesting talk about PHP, but ...

A thousands years ago, when I worked with PHP, I used this script to
send uploads:

sending it.

Oops, sorry.

I am sorry that i am asking again but i am trying to receive the file
with this code:
Code: [Select]<?php 
        $target_path = "upload/"; 

        $target_path = $target_path . "my_sent_file.html"; 

        if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $ta
rget_path)) { 
                echo "The file ". basename( $_FILES['uploadedfile']['n
ame'])." has been uploaded"; 
        } else{ 
echo "There was an error uploading the file, please try again!"; 
        }
?>
It should take sent file and save it to "upload/my_sent_file.html" but
it does nothing.
Does anybody know where is the problem? I am out of ideas...

QuoteIt should take sent file and save it to
"upload/my_sent_file.html" but it does nothing.Is the echo on if part
executed? Do your application has permission to write to that
directory? Could you try absolute path for destination?

Hey boss, so you is trying to send it via upload!

Please try this sample:

http://www.sendspace.com/file/p3j6ks

Open and run, it uses my host for tests.
