Strip out specific set of characters from Curl output in Shell [duplicate]

By -

So I have an api call that can output something such as this

{"access_token":"eyJjdHkiO_bxYJOOn28y5HGtGHgJzHVCE8zfy1qRBf_rhchA","token_type":"bearer","expires_in":900}

If I wanted to take that output and pull out just the content within the second set of quotes (the token), and put it into a variable for use in the script, what would be the easiest method of doing this?

Thanks for your help EDIT: I just checked the A DNS record for js.authorize.net and am getting the following result only: js.authorize.net. 100 IN CNAME js.authorize.net.cdn.cloudflare.net. Doing the same for js.authorize.net.cdn.cloudflare.net. does not return an A Record, unless I specifically instruct to use 1.1.1.1 as DNS server I...

Spring Elasticsearch Operations

By -
Elasticsearch Operations Spring Data Elasticsearch uses two interfaces to define the operations that can be called against an Elasticsearch index. These are ElasticsearchOperations and ReactiveElasticsearchOperations. Whereas the first is used with the classic synchronous implementations, the second one uses reactive infrastructure. The default implementations of the interfaces offer: Read/Write mapping support for domain types. A rich query and criteria api. Resource management and Exception translation.
