Rails接收参数作为字符串

Question

I'm building an API with Ruby on Rails. Because of that, I can't force the params to follow sone restriction.

Currently, I'm having an error with params that contained a Windows newline, because the newline isn't escaped.

The request body looks like below:

{
    "name": "Jon Do",
    "address": "6th Street\r\nDistrict City\r\nNation"
}

And it generated JSON::ParserError: 784: unexpected token

How to correctly process that request so params[:address] can be called without error?

Answer 1

When passing the data from front-end, make it JSON.stringify , and parse from back-end.

#Front-end
   address: JSON.stringify(objects)

#Back-end
   JSON.parse(params[:address])
