Как извлечь конкретный объект из файла JSON с помощью Python JSON

Question

Используя Python, мне нужно извлечь все конечные точки API (только имена конечных точек API) путем чтения из файла JSON.

Ниже приведен пример кода JSON,

}

Я попробовал следующий код:

import json
with open("example.json", "r") as reading:
        data = json.load(reading)
        print(data["paths"])

Здесь мне нужно пойти дальше кода, чтобы захватить только все имена конечных точек API.

В примере файла json, в разделе «Пути» мне нужно захватить все конечные точки и тип метода API, как показано ниже,

Кроме того, я также хотел бы получить значения для приведенных ниже ключей из примера кода JSON.

В разделе «Параметры» мне также нужно захватить следующие ключи, название: в: требуется:

Ожидаемый результат (только пример):

/service-provider/details
get
bus (comment - refers to the key - name under 'parameters')
query (comment - refers to the key - in under 'parameters')
false (comment - refers to the key - required under 'parameters')

/Bus/{bus-id}/names
get
bus-id (comment - refers to the key - name under 'parameters')
query (comment - refers to the key - in under 'parameters')
false (comment - refers to the key - required under 'parameters')

/busoperator/{bus-id}/names/routes
get
routes (comment - refers to the key - name under 'parameters')
query (comment - refers to the key - in under 'parameters')
false (comment - refers to the key - required under 'parameters')

/operator/{id}/route/path
get
id (comment - refers to the key - name under 'parameters')
query (comment - refers to the key - in under 'parameters')
false (comment - refers to the key - required under 'parameters')

Попробуйте это:

with open('example.json', 'r') as f:
    data = json.load(f)
    for path, values in data['paths'].items():
        print(path)
        for value in values:
            print(value)

Answer 2

Чтобы получить список из двух кортежей (конечная точка, тип), используйте:

[(endpoint, value.keys[0]) for endpoint, value in data["paths"].items()]
