Hi Fan,
A couple of things to try.
1. Use a field name to associate to the file: curl -X PUT
"http://localhost:8111"; -F "upload=@file.txt"
2. According to the @Put JavaDoc, you use a String return type with a
String argument. However, you usually don't need a return type from
a PUT since the common paradigm is to redirect to a GET. My
declaration looks like this:
public void accept(final Representation payload) throws Exception
{
...
final RestletFileUpload upload = new
RestletFileUpload(myDiskItemFactory);
final FileItemIterator fileItemIterator =
upload.getItemIterator(payload);
while (fileItemIterator.hasNext())
{
final FileItemStream nextFileItemStream = fileItemIterator.next();
if (nextFileItemStream.getFieldName().equals("upload"))
{
// Do upload stuff
}
}
}
And it works fine.
