post request body

When receiving a JSON request, I expected the request.data to include the keys and values, but instead it's a json string key and value that are identical, ie:

["{\"hello\":\"world\"}" : "{\"hello\":\"world\"}"]

Vapor currently only supports form encoded data. Issue #28 covers supporting JSON requests.

@tannernelson Cool, in the meantime, here's two different examples that work:

In case it helps, these are both functioning for me:

extension Request {
    public var jsonBody: Any? {
        var bytes = body
        let data = NSData(bytes: &bytes, length: body.count)
        return try? NSJSONSerialization
            .JSONObjectWithData(data, options: .AllowFragments)
    }
}

Or w/ pure json dependency:

.Package(url: "https://github.com/gfx/Swift-PureJsonSerializer", majorVersion: 1)

extension Request {
    public var jsonBody: Json? {
        return try? Json.deserialize(body)
    }
}

Does that compile on Ubuntu 14, 15, and OS X?

If so, you should submit that as a PR.

They both work on Heroku box, but the NSJSON version is relatively useless for anything but printing. It doesn't like it if I cast to [String : Any], and it doesn't like it if I cast to [String : AnyObject] on linux.

I think until Foundation adds official support, it might be worth using, or pointing to a 3rd party dependency. The PureJson version above runs on all instances and in my opinion, is a better way to deal with Json.

If you're interested in that, I can make a pull that includes the dependency. It's a little slower than NSJSON, but you also get the added benefit of being able to return:

return json.serialize(.PrettyPrint)

Which serializes more effectively

The NSJSON from Foundation won't work because it relies on the automatic casting of any Array or Dictionary to an NSArray or NSDictionary. I don't know if that's something that will ever be added to Linux.

So I think a dependency makes sense for serialization on Linux. If Apple does decide to include Foundation support at some point it can be removed.
