python - 如何在Python中发送带有路径参数的GET请求

Question

我在使用 Python 从 EatStreet Public API 发出 GET 请求时遇到问题。我已经在网站上的其他端点上取得了成功，但我不确定如何处理这种情况下的路径参数。

此curl请求返回200:

curl -X GET\ -H 'X-访问 token :API_EXPLORER_AUTH_KEY'\ 'https://eatstreet.com/publicapi/v1/restaurant/90fd4587554469b1f15b4f2e73e761809f4b4bcca52eedca/menu?includeCustomizations=false '

这就是我目前所拥有的，但我不断收到错误代码 404。我尝试了多种其他方法来弄乱参数和 header ，但似乎没有任何效果。

api_url = 'https://eatstreet.com/publicapi/v1/restaurant/
90fd4587554469b1f15b4f2e73e761809f4b4bcca52eedca/menu'
headers = {'X-Access-Token': apiKey}

def get_restaurant_details():

        response = requests.request("GET", api_url, headers=headers)
        print(response.status_code)

        if response.status_code == 200:
                return json.loads(response.content.decode('utf-8'))
        else:
                return None

<强> Passing Parameters In URLs

You often want to send some sort of data in the URL’s query string. If you were constructing the URL by hand, this data would be given as key/value pairs in the URL after a question mark, e.g. httpbin.org/get?key=val. Requests allows you to provide these arguments as a dictionary of strings, using the params keyword argument. As an example, if you wanted to pass key1=value1 and key2=value2 to httpbin.org/get, you would use the following code:

    payload = {'key1': 'value1', 'key2': 'value2'}
    r = requests.get('https://httpbin.org/get', params=payload)

通过打印 URL 可以看到 URL 已正确编码:

    print(r.url)
    https://httpbin.org/get?key2=value2&key1=value1

Note that any dictionary key whose value is None will not be added to the URL’s query string.

You can also pass a list of items as a value:

    payload = {'key1': 'value1', 'key2': ['value2', 'value3']}
    r = requests.get('https://httpbin.org/get', params=payload)
    print(r.url)
    https://httpbin.org/get?key1=value1&key2=value2&key2=value3

所以在你的情况下它可能看起来像

parameters = {'includeCustomizations':'false'}
response = requests.request("GET", api_url, params=parameters, headers=headers)
