Jmeter如何测试需要登录的接口

首先说明本系统的登录采用的是session，但是无论是什么登录步骤都是大差不差的

1.首先要构造用户测试的数据保存到数据库
在这里插入图片描述

2.构造请求获取请求后的请求头（如果需要代码参照请看最后）
3.解析请求头获取需要的cookie（sessionId是放在cookie中）或token。如果对header的结果无法把控就打印一个看一下结构再解析
4.保存所有的cookie或token到一个txt文件中

在这里插入图片描述

5.接下来就是jmter的测试环节，最基本得有这几个
在这里插入图片描述
选择刚刚生成的cookie.txt文件

使用${}获取即可
在这里插入图片描述
接下来测试即可

所有代码

    /*** 登录接口示例*/@PostMapping("/login")@ResponseBodypublic ResponseDTO userLogin(@Valid @RequestBody UserLoginReq req, HttpSession session, HttpServletRequest request)
