How to read data from an API which returns data in json in selenium webdriver?

Question

Basically i am firing a set of APIs using GET call which returns data in json, and i want to print only specific String like hostid as mentioned in below json snippet.

  "hostId" : 286,
  "parentSectionName" : "adadfr",
  "rank" : 86096.0,
  "activationStatus" : "ACTIVE",
  "overrideLinkProp" : 0,

There are a variety of libraries that you can use to parse JSON depending on what language you're using. Pick one that looks good to you. It might be part of your selenium tests, but you won't use the selenium library for dealing with JSON objects. — mrfreester

Assuming that your json looks like this:

        String jsonToDecode =   "{" +
         " \"hostId\" : 286,\n" +
            "  \"parentSectionName\" : \"adadfr\",\n" +
            "  \"rank\" : 86096.0,\n" +
            "  \"activationStatus\" : \"ACTIVE\",\n" +
            "  \"overrideLinkProp\" : 0,"+
            "}";

You can decode it using "com.googlecode.json-simple" package like so:

    JSONParser parser = new JSONParser();
    Object parsedJson = new Object();
    try {
        parsedJson  = parser.parse(jsonToDecode);
    } catch (ParseException e) {
        //do something when json parsing fails
    }
    JSONObject jsonObject = (JSONObject) parsedJson;
    String name = (String) jsonObject.get("parentSectionName");
    System.out.print(name); // will output adadfr

In java you can use JsonPath:

String jsonToDecode =   "{" +
         " \"hostId\" : 286,\n" +
            "  \"parentSectionName\" : \"adadfr\",\n" +
            "  \"rank\" : 86096.0,\n" +
            "  \"activationStatus\" : \"ACTIVE\",\n" +
            "  \"overrideLinkProp\" : 0,"+
            "}";
System.out.println(JsonPath.from(jsonToDecode).getString("hostId"));
