Access raw body and json body

[gerwinbrunner]

Hi,

how can I get the raw body and also the json body from a request?
Currently I use

Picker.middleware( bodyParser.json() );

And this works fine, but for security checks I would also need the raw body. How could I get both of them?

Best,
Gerwin

@gerwinbrunner Re: raw body. Have you tried just passing a function to Picker.middleware that listens for 'data'?

@gerwinbrunner I know this is coming really late, but I figured out how to do this in case it helps you or anyone else. From the body-parser documentation:

verify
The verify option, if supplied, is called as verify(req, res, buf, encoding), where buf is a Buffer of the raw request body and encoding is the encoding of the request. The parsing can be aborted by throwing an error.

So you can pass a verify function to bodyParser.json like this:
Picker.middleware(bodyParser.json({ verify: verifyParsing }));

and then in that function, grab out the raw body:

let rawBody;
const verifyParsing = (req, res, buf, encoding) => {
  rawBody = buf;
}
