Jmeter-提取Json数据进行关联

 

 

1：Json后置处理器提取结果作为下一个sampler的传入参数

1.1：【线程组】->【简单控制器】->【HTTP sampler】->【Beanshell后置取样器】->【查看结果树】

1.2：Beanshell后置取样器获取HTTP请求1所有响应数据returnData和其中单独的数据

log.info(returnData)可以在Log中输出returnData的值

1.4：添加第二个sampler

 

1.5：查看结果树 HTTP请求1的响应数据作为HTTP请求2的POST Data传入服务器

2：Beanshell对Json数据的增删改查

2.1：Beanshell后置处理器对响应数据的查询

 

2.1.1：eclipse的httpclient获取接口返回数据

Maven导入的Jar包

<!-- https://mvnrepository.com/artifact/com.alibaba/fastjson -->
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>fastjson</artifactId>
<version>1.2.47</version>
</dependency>

<!-- https://mvnrepository.com/artifact/org.apache.httpcomponents/httpclient -->
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
<version>4.5.5</version>
</dependency>

 

package Test.Json;

import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;
import org.junit.Test;

import com.alibaba.fastjson.JSONObject;

public class GetJsonData {

private String URL = "http://mobile.weather.com.cn/data/sk/101010100.html";

// Get方法获取 http://mobile.weather.com.cn/data/sk/101010100.html
@Test
public void GetMethodData() {

HttpGet httpGet = new HttpGet(URL);

CloseableHttpClient httpClient = HttpClients.createDefault();

try {
CloseableHttpResponse response = httpClient.execute(httpGet);

int code = response.getStatusLine().getStatusCode();// 获取返回状态码

System.out.println(code);

String returnData = EntityUtils.toString(response.getEntity());// 获取接口返回的text格式数据

System.out.println(returnData);
//======================================================================
// 将text格式数据转换成JSON格式数据
JSONObject jsonObject = JSONObject.parseObject(returnData);
// sk_inf为Json的一个节点 节点下采薇key value键值对
JSONObject data = jsonObject.getJSONObject("sk_info");
System.out.println(data);
//======================================================================
//增
data.put("phone", 110);
System.out.println(data);
//======================================================================
//删除
data.remove("cityName");
//======================================================================
//改
data.put("phone", 120);
//======================================================================
//查询
data.get("phone");

} catch (Exception e) {
System.out.println(e);
}
}
}

 

2.1.2：Beanshell对响应Json数据的删除

Beanshell后置处理器脚本

 

//导入Json jar包
import com.alibaba.fastjson.JSONObject;

String returnData = prev.getResponseDataAsString();
log.info(returnData);
//将获取的数据放入 方便下面的sampler取值
JSONObject jsonObject = JSONObject.parseObject(returnData);
JSONObject data = jsonObject.getJSONObject("sk_info");
//eclipse里面不用toString Jmeter中需要
log.info(data.toString());//这里输出有“北京”
data.remove("cityName");
log.info(data.toString());//这里输出没有"北京"

vars.put("returnData",returnData);
vars.put("data",data.toString());//data不是string形式变量 需要toString转换

 

HTTP请求2

查看结果树

2.1.3：Beanshell对响应Json数据的增

 

//导入Json jar包
import com.alibaba.fastjson.JSONObject;


String returnData = prev.getResponseDataAsString();
log.info(returnData);
//将获取的数据放入 方便下面的sampler取值
JSONObject jsonObject = JSONObject.parseObject(returnData);
JSONObject data = jsonObject.getJSONObject("sk_info");
//eclipse里面不用toString Jmeter中需要
log.info(data.toString());
data.put("name","Anndy");
log.info(data.toString());//这里输出增加"name":"Anndy"


vars.put("returnData",returnData);
vars.put("data",data.toString());//data不是string形式变量 需要toString转换

2.1.4：Beanshell对响应Json数据的改

 

//导入Json jar包
import com.alibaba.fastjson.JSONObject;


String returnData = prev.getResponseDataAsString();
log.info(returnData);
//将获取的数据放入 方便下面的sampler取值
JSONObject jsonObject = JSONObject.parseObject(returnData);
JSONObject data = jsonObject.getJSONObject("sk_info");
//eclipse里面不用toString Jmeter中需要
log.info(data.toString());//cityName:北京
data.put("cityName","南京");
log.info(data.toString());//这里输出增加"cityName":"南京"


vars.put("returnData",returnData);
vars.put("data",data.toString());//data不是string形式变量 需要toString转换

2.1.5：Beanshell对响应Json数据的查

 

//导入Json jar包
import com.alibaba.fastjson.JSONObject;


String returnData = prev.getResponseDataAsString();
log.info(returnData);
//将获取的数据放入 方便下面的sampler取值
JSONObject jsonObject = JSONObject.parseObject(returnData);
JSONObject data = jsonObject.getJSONObject("sk_info");
//eclipse里面不用toString Jmeter中需要
log.info(data.toString());
String city = data.get("cityName");


vars.put("returnData",returnData);
vars.put("city",city);

2.1.6：放入list集合

 

//导入Json jar包
import com.alibaba.fastjson.JSONObject;


String returnData = prev.getResponseDataAsString();
log.info(returnData);
//将获取的数据放入 方便下面的sampler取值
JSONObject jsonObject = JSONObject.parseObject(returnData);
JSONObject data = jsonObject.getJSONObject("sk_info");
//eclipse里面不用toString Jmeter中需要
log.info(data.toString());
//beanshell不能使用泛型
List list = new ArrayList();
list.add("AAA");
list.add("BBB");
list.add("CCC");
data.put("nameList", list);
//vars只能放入基础类型数据
vars.put("data",data.toString());//data不是基础类型 所以需要转换 否则会报错
