One of our clients is using .NET and we receive their data, however if they send it as “text/xml” mime type, I receive it at the controller parsed like:
However if they disable the content type in their code – removing this line: (//web.ContentType = “text/xml”
Then I get what I need and would expect:
{“<WEB_REQUEST>\n\t\n\t\t<POSTING_SYSTEM>zzzLending</POSTING_SYSTEM>\n\t\t<CLIENT_ID>LDAP</CLIENT_ID>\n\t\tft\n\t\tdir\n\t\n\t\n\t\t\n\t\t\tnew\n\t\t\t<DOCUMENT

Is there a way for me to handle within Rails the situation where they are posting the xml mime type? Really, I would expect them to be able to do so as it is in fact xml. Can I tell Rails to not do any magic to the incoming xml? (just kind of tacky to tell our client ‘I know it is an xml request, but dont send it with the xml content type’).

Probably. But I wonder if it's really the right thing to do.

Well, if I realized this before I might have. However I have a parser built with Nokogiri which handles my requests very nicely and makes no sense to redo it as it is solid and well tested.
I just noticed I can call
params[“WEB_REQUEST”].to_xml
So I could write a hack which (1) adds back the root <WEB_REQUEST> node, removes the node… but this is real ugly. Do you have any idea where I would look to disable this the right way?

which sounds like it is in the same part of the processing that you’re interested in. I don’t know whether it is supported in whichever version of rails you’re using, but it certainly seems like a good path to investigate.

As you can see in the private method "parse_formatted_parameters(env)"
the parsing of XML, JSON, YML, etc is based on mime-type.
It seems to me like one could possibly write a small custom middleware
that overrides the incoming mime-type and insert that middleware just
before ActionController::ParamsParser.
config.middleware.insert_before(existing_middleware, new_middleware,
args) – Adds the new middleware before the specified existing middleware
in the middleware stack.
Seems like that would effectively disable the automatic parsing of
incoming XML.
