How to access raw POST request content

[Diaoul]

Sorry if this is a dumb question I couldn't find any mention of this in the docs or examples.
Using ESP8266WebServer, I want to process the raw content of an incoming POST request.

Is that possible?

How do you meen the raw content of the POST request ?

[Diaoul]

Well, the data POST, after the headers. I'm not using application/x-www-form-urlencoded but json.

After digging in the source code of the library I found the answer, raw content is considered as an argument named "plain".

I leave the issue open because this is quite unusual and should be documented somewhere.

what do you think is the proper way to do it?

[Diaoul]

RFC defines the content of a request as the "message-body" (see https://tools.ietf.org/html/rfc7230#section-3)
I think "content" is also a good name and is used in the popular python library requests

[me-no-dev]

I vote for "messageBody" :) or just "body"

I also vote for body, the message part is implicit. It is also a name used by popular libraries, like the request module in Node.js

Another vote for getting this documented. Thanks for posting the issue and your findings; it helped me.

This issue can be closed. The documentation is available in the README.

arg - get request argument value, use arg("plain") to get POST body
