Parsing a JSON string in Ruby
(8 answers)
Closed 4 years ago.
Apologies if it is very basic one , completely new to ruby.
Below is the sample response I am getting while using the curl , need to get the values of body , created_at from the below output .
When I tried to check type of the value , puts returns true for (string) and false for hash and array
`#puts value.is_a?(Hash)
#puts value.is_a?(Array)
#puts value.is_a?(String)`
Not sure how to get value from the below output , Please help on with the first step/idea need to do here , will try on and revert back on getting any issues further

A new slave database node was created and placed into the rotation to guard against future master failures. The promoted slave database performed slowly for the next couple of hours as the query cache began to warm up, and eventually settled into a reasonable performance profile around 20:00 UTC.\r\n\r\n##### Future Mitigation Plans\r\n\r\nOver the past few months, we've been working on an overhaul to our data storage layer with a migration from a Postgres setup to a distributed, fault-tolerant, multi-region data layer using Riak. This initiative has been prioritized, and the migration will be performed in the coming weeks. We will notify our clients of the scheduled downtime via an incident on this status site, and via a blog post.",

Answer 1

It's JSON. Since you're using Rails, it will be sufficient to call
JSON.parse(value)
This will return an array of multiple hashes which you will be able to further map.
