Question

我希望locust能够登录我的Web应用程序并开始单击Web应用程序内的链接。

使用此代码，我只是通过登录获得首页的活动，而我没有从应用程序内部获得任何通知。

代码：

import random
from locust import HttpLocust, TaskSet, task
from pyquery import PyQuery


class WalkPages(TaskSet):
    def on_start(self):
        self.client.post("/", {
            "UserName": "my@email.com",
            "Password": "2Password!",
            "submit": "Sign In"
        })
       self.index_page()

    @task(10)
    def index_page(self):
        r = self.client.get("/Dashboard.mvc")
        pq = PyQuery(r.content)
        link_elements = pq("a")
        self.urls_on_current_page = []
        for l in link_elements:
          if "href" in l.attrib:
            self.urls_on_current_page.append(l.attrib["href"])

    @task(30)
    def load_page(self):
        url = random.choice(self.urls_on_current_page)
        r = self.client.get(url)


class AwesomeUser(HttpLocust):
    task_set = WalkPages
    host = "https://myenv.beta.webapp.com"
    min_wait = 20  * 1000
    max_wait = 60  * 1000

我在第一轮结束后在终端获得了跟踪消息。

Answer 1

您的清单可能是空的。

@task(30)
def load_page(self):
    if self.urls_on_current_page:
        url = random.choice(self.urls_on_current_page)
        r = self.client.get(url)

Answer 2

我需要时间，但有人可能需要这个。我在您的代码中发现的结果：登录请求似乎不正确（检查我是否正确），您无法从另一个函数到达函数内部定义的变量，因为task(10)不适合数据设置功能。将urls_on_current_page设置为类变量以供其他类成员使用。请参阅我的代码和评论：

import random
from locust import HttpLocust, TaskSet, task
from pyquery import PyQuery


class WalkPages(TaskSet):
    # define variable here to access them from inside the functions
    urls_on_current_page = []

    def login(self):
        self.client.post("/login", data = {"UserName": "mesutgunes@email.com", "Password": "password"})

    def get_urls(self):
        r = self.client.get("/Dashboard.mvc")
        pq = PyQuery(r.content)
        link_elements = pq("a")
        for link in link_elements:
            if key in link.attrib and "http" not in link.attrib[key]: 
            # there maybe external link on the page
                self.urls_on_current_page.append(link.attrib[key])


    def on_start(self):
        self.login()
        self.get_urls()


    @task(30)
    def load_page(self):
        url = random.choice(self.urls_on_current_page)
        r = self.client.get(url)


class AwesomeUser(HttpLocust):
    task_set = WalkPages
    host = "https://myenv.beta.webapp.com"
    min_wait = 20  * 1000 
    max_wait = 60  * 1000

使Locust登录Web应用程序
