Prevent Rails from encoding the ampersands in a URL when outputting JSON

问题

I have the following code:

render json: { image: image }

Image has an attribute "url". Let's say it's:

https://blah.com/a?A=B&C=D

When rendering, this is what I get:

{"image":{"url":"https://blah.com/a?A=B\u0026C=D"}}

The ampersand is getting encoded as \u0026

Is there any way to avoid this encoding?

回答1:

Add to your application.rb file:

config.active_support.escape_html_entities_in_json = false

回答2:

your answer described there:

Converting URL to JSON version?

JSON encoding wrongly escaped (Rails 3, Ruby 1.9.2)

Why does is Rails 4 unicode escaping in to_json

Encoding JSON in href using encodeURI, Rails parsing (article)

and also this would help you:

Jbuilder
