Redmine

Hello, I'm trying to create a Wiki page using REST API.
The page is created, but no files are attached.
I perform the following sequence of requests (below).

How can I attach a file to a wiki page in Redmine using REST API?

1)

POST /uploads.xml

<?xml version="1.0" encoding="UTF-8"?><upload><token>4.0aa1a60c74216523e275e92da1bc382a</token></upload>

2)

PUT /projects/test/wiki/Wiki.xml
<?xml version="1.0"?>
<wiki_page>
<text>Example 18.9cade8a56871e4867c97b5fbe2842f08</text>
