1. Import json package

 

2. Import JSON jar package-time format package (modified value used)

import com.alibaba.fastjson.JSON;
import com.alibaba.fastjson.JSONObject;

//import java.text.SimpleDateFormat;
import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;

3. Get the system variable -responsedata 

String response_data = prev.getResponseDataAsString();

4. Modify a field of json data.param.ciType.description Modify this field

JSONObject jsonObject=JSON.parseObject(response_data);
JSONObject paramJson = (JSONObject)((JSONObject) jsonObject.get("data")).get("param");
JSONObject ciTypeJsom = (JSONObject)paramJson.get("ciType");
ciTypeJsom.put("description",ciTypeJsom.get("description")+"_auto_"+LocalDateTime.now().format(DateTimeFormatter.ofPattern("yyyyMMddHHmm")));

//SimpleDateFormat sdf=new SimpleDateFormat("yyyyMMddHHmm");
//ciTypeJsom.put("description",ciTypeJsom.get("description")+"_auto_"+sdf.format(new Date()));
String responseData_a=jsonObject.toString();

5. System time-two ways to get it, remember to import the package-the original description becomes the description value plus + _auto_ + time

import java.text.SimpleDateFormat;

SimpleDateFormat sdf=new SimpleDateFormat("yyyyMMddHHmm");
ciTypeJsom.put("description",ciTypeJsom.get("description")+"_auto_"+sdf.format(new Date()));

import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;

ciTypeJsom.put("description",ciTypeJsom.get("description")+"_auto_"+LocalDateTime.now().format(DateTimeFormatter.ofPattern("yyyyMMddHHmm")));

6. Save variables

vars.put("responseData_b", responseData_a);

 

7. Get the string in json-the following transfer

1. Scenario 1: Obtain the data in the request response and save it

import com.alibaba.fastjson. *;   // Import package. This package needs to be placed in: <install directory> \ apache-jmeter-3.2 \ lib \ ext

// Get data 

String response = prev.getResponseDataAsString ();   // Get Response 

JSONObject responseObj = JSON.parseObject (response);   // The whole Response as JSON object 

JSONObject resObj = responseObj.getJSONObject ("res");   // Get a certain Part of the object. That is, the content of {} in the json string 

JSONArray listArray = resObj.getJSONArray ("list");   // Get the list. That is, the contents of [] in the json string

// Save data

// 1) List

int len = listArray.size();

for(int i=0; i<len; i++){

    temp[i] = listArray.get(i).getString("name");

}

vars.put ( "names", Arrays.toString (temp));   // Save to JMeter variable, vars.put can only save string, so toString () is used here for conversion

// 2) String type 

String id = resObj.get ("id");   // Get the content of a string in the object. 

vars.put ( "id", id);   // Save to JMeter variable, the following components can be used

// 3) Integer type 

Integer no = resObj.get ("id");  // Get the content of an integer in the object. 

vars.put ( "no", no.toString ());    // Save to JMeter variable, vars.put can only save string, so toString () is used here for conversion

2. Scenario 2: Obtain the data queried in the database and save it

Premise: The data has been obtained in JDBC Request. For details, please refer to "Usage of JDBCRequest".

select total_cash from t_cash where user_name="tom";

The value in Result variable name is: result

String cash_new = vars.getObject("result").get(0).get("total_cash").toString();

vars.put ( "cash_new", cash_new);   // The same as this step before operation, no more details. The saved variable is named cash_old
