Note:
- Pass
${apps.home}in studio VM args or from property files. To run in studio:-Dapps.home=/Users/<user>/studio/workspace/upload/src/main/resources - In the code,
payload."parts"."file"."content", the object "file" is from the below HTML input name for file tag. If you change the name in HTML, then the same needs to be used.<input type="file" required="required" name="file"> - Instead of using a parse template, we can also use the Load static resources component.
HTML Code:
HTML
x
13
1
<html lang="en"><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
2
<title>File Upload</title>
3
</head>
4
<body>
5
<div class="container">
6
<form method="POST" action="/upload" enctype="multipart/form-data">
7
<h3>File Upload</h3>
8
<input type="file" required="required" name="file">
9
<button type="submit">Submit</button>
10
</form><br>
11
<font color="green"> #[if (vars.status != null) 'File upload: ' ++ vars.status else '']</font>
12
</div>
13
</body></html>
Note:
- Keep this HTML file in <app-name>/src/main/resources/web-page
- action="upload" invokes the above Mule flows
