JMeter JSON extractor extracts two parameters at the same time

Two interfaces A、B, Interface B Interface required A Two parameters returned , from A Get the return value of the same object at random orderType and orderformId,

Interface A The return value of ：

{
    "list": [
        {
            "orderType": "1",
            "orderformId": "2562",
        },
        {
            "orderType": "1",
            "orderformId": "2546",
           
        },
        {
            "orderType": "0",        
            "orderformId": "2430",
        }
    ]
}

json Extractor parameters ：

json path expressions：$.list[1].orderformId;$.list[1].orderType , In this way, only one fixed object can be specified ; and $.list[*].orderformId;$.list[*].orderType,Match No ：0;0    The two objects selected are random , The values of the two extracted parameters are different from the same object .

Solutions ：json  Expression , Parameterize the array index , According to the interface A The size of the returned array , Generate random number , Pass in json  expression .（ There are many ideas ： utilize json The extractor randomly selects an object , Reuse Bean Sell  The code takes the value of two parameters ... Never tried. ）.

utilize Bean Sell Read the return value of the interface , Use regular expressions to determine the number of objects （json Processing seems to be guided , lazy , Regular substitution ）, Generate random numbers for a specified range , Save variables , for json The extractor uses .

Bean Sell  Code ：

import java.util.regex.Matcher;
import java.util.regex.Pattern;

data = prev.getResponseDataAsString();
subs = "\"orderType\"";
Pattern pattern = Pattern.compile(subs); 
Matcher matcher = pattern.matcher(data); 
int count=0; 
while(matcher.find()){ 
    count++; 
} 
int i = new Random().nextInt(count-1);
vars.put("i",i+"");//vars.put("","") No numbers , Convert to string

json path expressions To configure ：$.list[${i}].orderformId;$.list[${i}].orderType.
