　　引言

　　前面已经介绍Locust基本使用与案例分享，脚本已经写好后，我们仅仅只是完成了一小部分的工作，对于监控到的数据展示以及后面的数据准确性分析、问题定位等等，我们并没有讲到。该篇简单分享一下Locust界面上面基本知识与使用。

　　UI界面

　　这里就不重复讲解脚本中的代码了，如果不懂，建议从头看起。

　　脚本如下：

from locust import TaskSet,HttpLocust,between,task



class TestLogin(TaskSet):



    def setup(self):
        print("开始...")

    def teardown(self):
        print("结束...")

    def _login(self):
        url = '/api/private/v1/login'
        body = {
            "username": "admin",
            "password": "123456"
        }
        r = self.client.post(url=url, data=body)
        print("测试")
        print("响应数据是:%s"%r.text)
        assert "登录成功" in r.text
        return r.json()['data']['token']

    def logout(self):
        print("退出系统")

    @task(1)
    def goods_list(self):
        url = '/api/private/v1/goods'
        params = {
            "pagenum":1,
            "pagesize":10
        }
        headers = {
            'Authorization': self._login()
        }
        r = self.client.get(url=url,params=params,headers=headers)
        print(r.text)
        print("获取商品列表")

    @task(1)
    def user_list(self):
        url = '/api/private/v1/users'
        params = {
            'pagenum':1,
            'pagesize':1
        }
        headers = {
            'Authorization':self._login()
        }
        r = self.client.get(url=url,params=params,headers=headers)
        print(r.text)
        print("获取用户列表")

    def on_start(self):
        """ on_start is called when a Locust start before any task is scheduled """
        print("启动")
        self._login()

    def on_stop(self):
        """ on_stop is called when the TaskSet is stopping """
        print("停止")
        self.logout()

import random

class WebsiteUser(HttpLocust):
    task_set = TestLogin
    def setup(self):
        print('locust setup')

    def teardown(self):
        print('locust teardown')
    wait_time = between(5,6)
    wait_function = lambda self: random.expovariate(1) * 1000


if __name__ == '__main__':
    import os
    os.system('locust -f locustfile_pro.py --host=http://127.0.0.1:8899 --port=8084')

　　启动界面

名词解析：

Number of users to simulate：设置模拟的用户总数

　　Hatch rate (users spawned/second)：每秒启动的虚拟用户数

　　Start swarming：执行locust脚本

　　测试监控界面

　　Statistics类似Jmeter中的聚合报告

　　名词解析：

　　Type：请求类型，即接口的请求方法；　　Name：请求名称；　　requests：当前已完成的请求数量；　　fails：当前失败的数量；　　Median：响应时间的中间值，即50%的响应时间在这个数值范围内，单位为毫秒；　　90%ile：根据正态分布，90%的响应时间在正态分布平均值下方，即小于这个值；　　Average：平均响应时间，单位为毫秒；　　Min：最小响应时间，单位为毫秒；　　Max：最大响应时间，单位为毫秒；　　average Size：平均每个请求的数据量，单位为字节；　　current RPS（requests per second）：每秒钟处理请求的数量，即RPS。（以前叫reqs/sec：每秒钟处理请求的数量，即QPS；），所以这两个可以看成一个。
