1. Open Fiddler packet capture function
2. Download the file in the platform to be tested
3. View download-related data captured by Fiddler, and view the incoming parameters
4. Create a Jmeter HTTP request and pass in the above parameters.

Use regular to extract the current file name:

use BeanShell to save the returned body content to the local:

BeanShell code

//获取上个请求的返回数据

byte[] result = prev.getResponseData();

String f = vars.get("filename_01"); 
String file_name = "D:/a/".concat(f); 
File file = new File(file_name);

FileOutputStream out = new FileOutputStream(file);

out.write(result);
