The mod_python.publisher implementation always decodes form parameters
regardless of whether the method being called can accept any and also ignores
whether the content type is even of a type where form parameters can be
decoded in the first place. This means that it is not possible using the
mod_python.publisher module to implement a method which accepts POST
requests with a inbound content type such as "text/xml". Attempting to do
so yields an error such as:
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>
<title>501 Method Not Implemented</title>
</head><body>
<h1>Method Not Implemented</h1>
<p>POST to /xmlrpc/service not supported.<br />
</p>
<hr />
<address>Apache/2.0.51 (Unix) mod_python/3.1.4 Python/2.3 Server at localhost Port 8080</address>
</body></html>
The "Method Not Implemented" error in this case is due to FieldStorage
rejecting the content type of "text/xml".
A check could be added to ensure that FieldStorage is only used to decode
form parameters if the content type is appropriate. Ie.,
if not req.headers_in.has_key("content-type"):
content_type = "application/x-www-form-urlencoded"
else:
content_type = req.headers_in["content-type"]
if content_type == "application/x-www-form-urlencoded" or \
content_type[:10] == "multipart/":
req.form = util.FieldStorage(req,keep_blank_values=1)
Because req.form is passed to util.apply_fs_data(), code where it is called
would need to be changed to pass None instead and util.apply_fs_data()
would need to be modified to see that the argument is None and not do
the field conversion process of stuff in the form etc etc.
