Error submit process, can not download application/octet-stream.
Hi... I am a LaTeX user. I don't know HTML, JavaScript... My purpose, is to download a file, from a PDF file I created from an internet site. Here is the HTML example. Good working.
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Post method example</title>
<style>
form {
width: 420px;
}
div {
margin-bottom: 20px;
}
label {
display: inline-block;
width: 240px;
text-align: right;
padding-right: 10px;
}
button, input {
float: right;
}
</style>
</head>
<body>
<form action="https://edu.casio.com/education/activity/download.php" method="post">
<div>
<label for="say">FILE NO:146</label>
<input name="dl_FILE_NO" value="146">
</div>
<div>
<label for="to">FILE NAME:fx991esplus.pdf</label>
<input name="dl_FILE_NAME" value="fx991esplus.pdf">
</div>
<div>
<label for="to">FILE CD:1</label>
<input name="dl_FILE_CD" value="1">
</div>
<div>
<button>Submit</button>
</div>
</form>
</body>
</html>
Here is the LaTeX example.
\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{lmodern}
\usepackage{hyperref}
\usepackage[pdftex]{insdljs}
\usepackage[pdftex]{eforms}
\begin{document}
\begin{Form}[action={https://edu.casio.com/education/activity/download.php},encoding=html,method=post]
\TextField[name=dl\_FILE\_NO,value={146}]{NO:}
\TextField[name=dl\_FILE\_NAME,value={fx991esplus.pdf}]{NAME:}
\TextField[name=dl\_FILE\_CD,value={1}]{CD:}
\Submit{Send}
\end{Form}
\href{https://www.gimp.org/}{GNU Image Manipulation Program}
\end{document}
My PDF file...

The PDF file I generated with LaTeX code first gave the following error, click the Send Key,

Then the following window appeared when I wrote http instead of https, click the Send Key,

What should I do? How can I solve this problem? I'm waiting for your help. Maybe I could have opened it in the wrong discussion place. My system, Adobe Reader Version 9.5.5 04/26/2013 - Firefox 54.0 (64 BIT) - Ubuntu 16.10.
