Making a curl to an API and get an specific field from the JSON


json shell parsing http curl

By using jq you could parse the json data instead of the text based parsing.

curl -X GET "https://api.mercadolibre.com/items/MLA511127356" | jq '.[].id'

As mentioned here you can use grep -Po '"keyThatYouWant":.*?[^\\]",' file.json. Like that:

local result=$(curl -X GET $YOUR_HUGE_URL)echo $result | grep -Po '"keyThatYouWant":.*?[^\\]",'

jq is pretty impressive but if you do not want to install another dependency, using python is a nice alternative by also giving you some extra flexibility if further processing is desired.

Jist of it is to pipe the json curl result to python -c.

Example:

curl -X GET https://jsonplaceholder.typicode.com/comments/4 | python -c "import sys,json; print json.load(sys.stdin)['email']"
