Python 在Hocust中，如何从一个任务获得响应并将其传递给另一个任务

我已经开始使用蝗虫做性能测试。 我想将两个post请求发送到两个不同的端点。但是第二个post请求需要第一个请求的响应。如何以方便的方式进行此操作。我试过像下面这样，但没有工作

from locust import HttpLocust, TaskSet, task

class GetDeliveryDateTasks(TaskSet):

    request_list = []

    @task
    def get_estimated_delivery_date(self):
        self.client.headers['Content-Type'] = "application/json"
        response = self.client.post("/api/v1/estimated-delivery-date/", json=
        {
            "xx": "yy"

        }
          )
        json_response_dict = response.json()
        request_id = json_response_dict['requestId']
        self.request_list.append(request_id)


    @task
    def store_estimated_delivery_date(self):
        self.client.headers['Content-Type'] = "application/json"
        response = self.client.post("/api/v1/estimated-delivery-date/" + str(self.request_list.pop(0)) + "/assign-order?orderId=1")


class EDDApiUser(HttpLocust):
    task_set = GetDeliveryDateTasks
    min_wait = 1000
    max_wait = 1000
    host = "http://localhost:8080"

您可以在启动时调用

（self）

函数，在传递到

任务

列表之前为您准备数据。见下例：

from locust import HttpLocust, TaskSet, task

class GetDeliveryDateTasks(TaskSet):

    request_list = []

    def get_estimated_delivery_date(self):
        self.client.headers['Content-Type'] = "application/json"
        response = self.client.post("/api/v1/estimated-delivery-date/", json=
        {
            "xx": "yy"

        }
          )
        json_response_dict = response.json()
        request_id = json_response_dict['requestId']
        self.request_list.append(request_id)

    def on_start(self):
        self.get_estimated_delivery_date()


    @task
    def store_estimated_delivery_date(self):
        self.client.headers['Content-Type'] = "application/json"
        response = self.client.post("/api/v1/estimated-delivery-date/" + str(self.request_list.pop(0)) + "/assign-order?orderId=1")


class EDDApiUser(HttpLocust):
    task_set = GetDeliveryDateTasks
    min_wait = 1000
    max_wait = 1000
    host = "http://localhost:8080"
