如何从响应中提取值并使用请求库将其与另一个值进行比较？

Question

我正在向两个不同的 API 发出两个请求。如何从响应中提取一个值，从第二个响应中提取另一个值并进行比较？非常喜欢！

import requests

BASE_PATH = "https://example_url.com"
ACCESS_TOKEN = "1111"


def fill_basket():
    basket_data = {
            "article": "13",
            "some_info1": "1"
            "some_info2": "2"
    }
    r = requests.post(f"{BASE_PATH}/api/v5/basket/create/",
                      headers={"X-Access-Token": f"{ACCESS_TOKEN}"},
                      json=basket_data
    )
    assert r.status_code == 200, r.text
    return r.json()["some_id"] #here i tried to catch value from the response 1 
fill_basket()

def check_basket():
    b = requests.post(f"{BASE_PATH}/api/v5/basket/calculate/",
                     headers={"X-Access-Token": f"{ACCESS_TOKEN}"}
    )
    assert b.status_code == 200, b.text
    return b.json()["some_id"] #here i tried to catch value from the response 2
check_basket()


assert r.json()["some_id"] == b.json()["some_id"]

此处响应check_basket请求：

{
    "quantity": 1,
    "cost": 10,
    "pricesCurrentCountry": {
        "cost": 10,
        "oldCost": 20,
        "discount": 10
    },
    "productList": [
        {
            "some_id": "39KK8ME6BTEL27",
            "article": "101",
        }
    ]
}

此处对 fill_basket 请求的响应：

{
    "some_id": "39KK8ME6BTEL27",
    "quantity": 1,
    "paymentMethodId": null,
}

根据您对“函数外的变量”的评论，此 Real Python article about scopes 可能会对您有所帮助。

由于您的函数正在返回值，您可以直接比较这些值（方法 2）或创建一个标识符来引用它们（方法 1）。

import requests

BASE_PATH = "https://example_url.com"
ACCESS_TOKEN = "1111"


def fill_basket():
    basket_data = {
        "article": "13",
        "some_info1": "1",  # A missing comma caused a syntax error here
        "some_info2": "2"
    }
    r = requests.post(f"{BASE_PATH}/api/v5/basket/create/",
                      headers={"X-Access-Token": f"{ACCESS_TOKEN}"},
                      json=basket_data
                      )
    assert r.status_code == 200, r.text
    # here i tried to catch value from the response 1
    return r.json()["some_id"]


def check_basket():
    b = requests.post(f"{BASE_PATH}/api/v5/basket/calculate/",
                      headers={"X-Access-Token": f"{ACCESS_TOKEN}"}
                      )
    assert b.status_code == 200, b.text
    # here i tried to catch value from the response 2
    return b.json()["productList"][0]["some_id"]


# Approach 1
# Follow this approach if you need to re-use the data.
x = fill_basket()
y = check_basket()
assert x == y

# Approach 2
# Or if you don't need to re-use the data, do this.
assert fill_basket() == check_basket()
