POST json data with cURL from a while loop - bash shell

Question

I have a JSON output from which I need to extract an ID and Iterate through them and send multiple request to API execute REST API with curl. For example:

This is how the JSON output looks like:

{
    "glossary": [
        {
            "Title": "example glossary1",
            "id": 1,
            "description": "Hello Glossary1"
        },
        {
            "Title": "example glossary2",
            "id": 2,
            "description": "Hello Glossary2"
        },
        {
            "Title": "example glossary3",
            "id": 3,
            "description": "Hello Glossary3"
        },
        {
            "Title": "example glossary4",
            "id": 4,
            "description": "Hello Glossary4"
        }
    ]
}

The shell script should loop through this JSON file, extract the ID and loop through and execute REST API calls with CURL.

Here is example:

for (( i = 0 ; i < ${#id[@]} ; i++ ))
do 
     POST REST API 
done

Solution

If you have you output in a file called tmp.json use jq to get the list of ids, one per line and then with a simple for loop make a post to your api

for i in `cat tmp.json  | jq .glossary[].id`; do 
   curl -X POST http://host/api/$i"
done
