The headers have to be json or else it doesn't work. e.g. it won't work if content-type is text/html

Beautiful! It would be great if there was a sort by key option.

Great Plugin. I've used others that just pretty print the JSON. This one gives you options: + Option to see raw format + Option to see parsed format + Can collapse nested structures/arrays + When collapsed details how many items are hidden.

HTTP Header里必须得有 "Content-Type: application/json" 不然不会自动格式化的。。。

Awesome tool! Commenting the number of items in a collection is very helpful.
