如何使用齐射解析json数据

Question

I am using volley lib. at every activities in my project my first login page has done using volley JSON Object Request method(POST) and next activities could not parsed.

Json data of the main screen:

{
"err-code": 5,
  "job_details": [
    {
      "job_id": 33,
      "job_no": "ES53-AF",
      "contract_manager_id": 4,
      "company_name": "A Construction  Ltd",
      "time_spent": 4.5
    },
    {
      "job_id": 5,
      "job_no": "ES1465-AF",
      "contract_manager_id": 4,
      "company_name": "Trios Property",
      "job_description": "Carry out the rewire of ",
      "time_spent": 26.5
    },
    {
      "job_id": 81,
      "job_no": "ES101-AF",
      "contract_manager_id": 4,
      "company_name": "Arden Construction  Ltd",
      "job_description": "Carry out works as per esti 3AQ",
      "time_spent": 2.5
    },
  }]
}

Code:

private  void getDataNew()
{
   String url = "http://103.5.103.8:067/ivservices/Webservices/joblisting";
    HashMap<String, String> user = session.getUserDetails();
    String token = user.get(SessionManager.KEY_TOKEN);
    Log.e("token check kro", token);
    final String role = user.get(SessionManager.KEY_ROLE);
    Log.e("role", role);
    String user_id = user.get(SessionManager.KEY_USERID);
 // Log.e("user_id", user_id.toString());
    Map<String, String> params = new HashMap();
    params.put(KEY_TOKEN, token);
    params.put(KEY_ROLE, role);
    params.put(KEY_ID, user_id);

        JSONObject parameters = new JSONObject(params);

        JsonObjectRequest jsonRequest = new JsonObjectRequest(Request.Method.POST, url, parameters, new Response.Listener<JSONObject>() {
            @Override
            public void onResponse(JSONObject response) {
               // Log.e("response mila", response.toString());
                parseData(response);
            }
        }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error)
            {
                error.printStackTrace();
                //TODO: handle failure
            }
        });

    Volley.newRequestQueue(this).add(jsonRequest);
    }

Answer 1

Try this

Note Check Also your json remove ,} before ] than you have without syntax error response

 try {

        int err_code=response.getInt("err-code");

        JSONArray jsonArray=response.getJSONArray("job_details");
        for(int i=0;i<jsonArray.length();i++)
        {
            JSONObject jsonObjectdetail=jsonArray.getJSONObject(i);

            int job_id=jsonObjectdetail.getInt("job_id");
            int time_spent=jsonObjectdetail.getInt("time_spent");
            int contract_manager_id=jsonObjectdetail.getInt("contract_manager_id");
            String job_no=jsonObjectdetail.getString("job_no");
            String company_name=jsonObjectdetail.getString("company_name");
        }
    } catch (JSONException e) {
        e.printStackTrace();
    }

Answer 2

remove Extra }, from your json.

one mistake you did in json parsing code you replied to @Er. Arjun saini .

that mistake is in this line :

JSONArray jsonArray = Object.getJSONArray(" err-code ");

it should be like this :

JSONArray jsonArray = Object.getJSONArray(" job_details ");

Make sure json should be like this:

    {


"err-code": 5,
  "job_details": [
    {
      "job_id": 33,
      "job_no": "ES53-AF",
      "contract_manager_id": 4,
      "company_name": "A Construction  Ltd",
      "time_spent": 4.5
    },
    {
      "job_id": 5,
      "job_no": "ES1465-AF",
      "contract_manager_id": 4,
      "company_name": "Trios Property",
      "job_description": "Carry out the rewire of ",
      "time_spent": 26.5
    },


{
  "job_id": 81,
  "job_no": "ES101-AF",
  "contract_manager_id": 4,
  "company_name": "Arden Construction  Ltd",
  "job_description": "Carry out works as per esti 3AQ",
  "time_spent": 2.5
}
  ]
}

And Try this code hope it will work if not work than please share logcat errors and exceptions

try {
        JSONObject Object=new JSONObject(response);
        int code = Object.getInt("err-code");
        if (code == 0) {
            JSONArray jsonArray = Object.getJSONArray("job_details");
            List<JobList> jobListArray=new ArrayList<JobList>();
            for (int i = 0; i <= jsonArray.length(); i++) { 
                JSONObject jsonObject = (JSONObject) jsonArray.get(i);
                JobList model_joblist=new JobList();
                model_joblist.setJobno(jsonObject.getString(JobList.JOB_NO));
                model_joblist.setJobid(jsonObject.getInt(JobList.JOB_ID));
                model_joblist.setDescreption(jsonObject.getString(JobList.JOB_DESCRIPTION));
                jobListArray.add(model_joblist);
            }
        }
    } catch (JSONException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

if it still not work than there is error in any other code eg in json are in your model_joblist etc.

share more code and logcat please.
