locust参数化

前面用篇专门讲了requests实现接口的参数关联案例，这里直接转化成locust脚本就行了

from locust import HttpLocust, TaskSet, task
from lxml import etree

class LoginDemo(TaskSet):
    '''用户行为描述'''

        }
        self.client.headers.update(h1)
        r = self.client.get("/passport/login", verify=False)
        # 从返回html页面，解析出lt、execution
        dom = etree.HTML(r.content.decode("utf-8"))
        try:
            result["lt"] = dom.xpath('//input[@name="lt"]')[0].get("value")
            result["execution"] = dom.xpath('//input[@name="execution"]')[0].get("value")
            print(result)
        except:
