**一 .编写测试任务**

1.1 编写测试任务

右键测试计划,找到线程组点击进去

1.3添加http请求并

**二 设置下载的文件保存到本地**

2.1 添加BeanShell PostProcessos

在Script添加java代码

**内容如下**

import java.io.*;
    
    import java.util.UUID;
    
    
    //获取上个请求的返回数据
    
    byte[] result = prev.getResponseData();
    
    //要下载到什么地方
    
    String file_name = "C:\\resources\\"+UUID.randomUUID().toString()+".jpg";
    
    File file = new File(file_name);
    
    FileOutputStream out = new FileOutputStream(file);
    
    out.write(result);
    
    out.close();

file\_name变量表示存储到本地的路径加文件名称

**三 执行任务并查看结果**

查看下载到本地的图片，400个项目对应着设置的并发线程量数量,表示请求都成功了
