关于性能优化:性能工具之locust工具get与post请求

最近在学习 locust 性能工具，发现 locust 性能工具脚本须要 python 根底能力写脚本，然而对于性能测试人员来说 python 是根本功夫。

在 locust 中 get 脚本怎么写，为了不便间接在代码运行调试，采纳敞开 web 模式，通过参考官网文档本人试验 get/post 代码，参考代码如：
@task(1)

def get_7dTest(self):
    # 定义申请头
    header = {"User-Agent": "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/69.0.3497.100 Safari/537.36"}
    response = self.client.get("/7d/", headers=header, verify=False)
    # print("Response status code:", response.status_code)
    if response.status_code == 200:
        print("successful")
        # print("Response text:", response.json())
    else:
        print('failure')

post 申请写法如下
# 登陆 

@task(1)
def get_login(self):
    response = self.client.post("/login", {"userName": "7d", "passWord": "123456"})
    print("Response json:", response.json())

post 申请 json 申请写法：
@task(1)

def get_login_json(self):
    jsonData = {"userName": "7d", "passWord": "123456"}
    response = self.client.post("/login/json", json=json.dumps(jsonData))
    print("Response json:", response.json())

后果

Response json: {‘msg’: ‘success’, ‘code’: 0, ‘data’: ‘ 登陆胜利 ’}

试验申请资源代码：

@GetMapping("/7d")
@ResponseBody
public R indexPage() {HashMap<String, Object> map = new HashMap<>();
    map.put("success", "欢送来到性能实战课堂");
    map.put("Data", new Date());
    return R.ok().put("data", map);
}

/**

 * 登陆
 *
 * @param memberEntity
 * @return
 */
@PostMapping("/login")
@ResponseBody
public R login(MemberEntity memberEntity) {if ("7d".equals(memberEntity.getUserName()) && "123456".equals(memberEntity.getPassWord())) {return R.ok().put("data", "登陆胜利");
    }
    return R.error().put("data", "用户名或者明码失败");
}


/**
 * 登陆
 *
 * @param requestBody
 * @return
 */
@PostMapping(value = "/login/json", produces = "application/json")
@ResponseBody
public R login_json(@RequestBody String requestBody) {log.info("json 数据：{}", requestBody);
    Object parse = JSON.parse(requestBody);
    MemberEntity memberEntity = JSON.parseObject(parse.toString(), MemberEntity.class);
    if ("7d".equals(memberEntity.getUserName()) && "123456".equals(memberEntity.getPassWord())) {return R.ok().put("data", "登陆胜利");
    }
    return R.error().put("data", "用户名或者明码失败");
}

locust 间接在 python 代码调试代码敞开 web 页面，这样调试很不便，参考如下命令：

os.system(“locust -f demoLcou.py –host=http://127.0.0.1:8080 –headless -u 1 -r 1 -t 1s”)
# –no-web 示意不应用 Web 界面运行测试。
# -c 设置虚构用户数。
# -r 设置每秒启动虚构用户数。
# -t 设置设置运行工夫。

总结：
locust 官网文档还是比拟具体，只有缓缓看就能把握 locust 工具怎么操作，然而在老师性能工程中，工具只有能发压就行。
