Groovy - json 的访问元素

Question

I have this json output:

{"UT":{
  "test_results":[
   [
     {
         "branches": "8",
          "build": "normal"
     },
     {
         "branches": "8",
         "build": "normal"
     }
   ]
  ],
 }
}

I use this piece of code:

            def json = JsonOutput.toJson(br2)
            def parsed = new groovy.json.JsonSlurper().parseText(json)

I parse the text but how could I access the values of build?

Answer 1

The JsonSlurper().parseText(json) call will return a LazyMap. From there, you can interact with it as you would with any map. The offcial groovy docs have an approachable explainer here .

In your case, there are multiple ways to get the values of build. Your json structure seems to have an extra list wrapping the test_results objects. If this is constant, you can do something like:

assert parsed["UT"]["test_results"][0]["branches"] == ["8", "8"]

alternatively, you can simply flatten the values returned by direct access:

assert parsed["UT"]["test_results"]["branches"].flatten() == ["8", "8"]
