Passing JSON objects to jq arguments

Question

Data sample - sample.json (full sample: https://pastebin.com/KFkVmc2M)

    {
      "ip": 3301234701,
      "_shodan": {
        "options": {
          "referrer": "7ae15507-f5cc-4353-b72e-5cc0b1c34c5e"
        },
      },
      "hash": -1056085507,
      "os": null,
      "title": "WHM Login",
      "opts": {
        "vulns": ["!CVE-2014-0160"],
        "heartbleed": "2017/08/29 09:57:30 196.196.216.13:2087 - SAFE\
        }
      },
      "isp": "Fiber Grid Inc",
      "http": {
        "redirects": [],
        "title": "WHM Login",
        "robots": null,
        "favicon": null,
        "host": "196.196.216.13",
        "html":
}

Script using jq which I hoped would work and haven't found a another solution yet.

   cat sample.json | jq \
   --arg key0   'Host' \
   --arg value0 '.host' \
   --arg key1   'Vulnerability' \
   --arg value1 '.opts.vulns[0]' \
   --arg key2   'ISP' \
   --arg value2 '.isp' \
   '. | .[$key0]= $value0 | .[$key1]=$value1 | .[$key2]=$value2' \
   <<<'{}'

The end result I hoped, but not getting:

{
  "Host": "196.196.216.13",
  "Vulnerability": "!CVE-2014-0160",
  "ISP": "Fiber Grid Inc"
}

Right now it just returns the object as a string and I've tried a lot of different ways to approach the problem. I am quite new to working with JSON and jq but based on what I've read so far, the solution might not be as simple as I'm wishing?

Simply put, why isn't the object being returned as a value of the sample.json object and what do I have to do, to make it work?

Thanks!

Answer 1

Here's a variant solution using the approach suggested by @CharlesDuffy:

$ config='{"Host": ["http", "host"], 
           "Vulnerability": ["opts", "vulns", 0], 
           "ISP": ["isp"]}'
$ jq --argjson config "$config" '
   . as $in
   | $config
   | map_values( . as $p | $in | getpath($p) )' pastebin.json

Output:

{
  "Host": "196.196.216.13",
  "Vulnerability": "!CVE-2014-0160",
  "ISP": "Fiber Grid Inc"
}

This incidentally highlights @chepner's point: the care and maintenance required for $config is no less than the care and maintenance required for the corresponding jq query, whereas the jq query language -- by design -- offers far more flexibility.
