如何检查 Python HTTP 请求中存在哪些 JSON 数据？

Question

我正在使用 Python 编写一个脚本，该脚本将使用我在网上找到的 API 生成笑话。 (https://sv443.net/jokeapi/v2/)。然而，笑话的一些设置/问题部分使用 JSON 数据，它在“设置”和“笑话”之间变化。我正在寻找是否可以编写一个脚本来检查响应是拉哪一个。我的脚本在这里：

import requests
import json

def getJoke():
  response = requests.get("https://v2.jokeapi.dev/joke/Any")
  print(response.text)
  json_data = json.loads(response.text)
  joke = json_data['joke'] + json_data['setup'] + " " + json_data['delivery']
  print(joke)

getJoke()

有些回答是

    "error": false,
    "category": "Christmas",
    "type": "twopart",
    "setup": "How will Christmas dinner be different after Brexit?",
    "delivery": "No Brussels!",

和

    "error": false,
    "category": "Programming",
    "type": "twopart",
    "joke": "Why is Linux safe?",
    "delivery": "Hackers peak through Windows only.",

有没有办法检查响应获得的数据名称？

Answer 1

有两种类型的笑话。单衬里和多部分衬里。

单行笑话：

{
    "error": false,
    "category": "Pun",
    "type": "single",
    "joke": "To whoever stole my copy of Microsoft Office, I will find you. You have my Word!",
    "flags": {
        "nsfw": false,
        "religious": false,
        "political": false,
        "racist": false,
        "sexist": false,
        "explicit": false
    },
    "id": 191,
    "safe": true,
    "lang": "en"
}

多部分笑话：

{
    "error": false,
    "category": "Programming",
    "type": "twopart",
    "setup": "Why do programmers prefer using the dark mode?",
    "delivery": "Because light attracts bugs.",
    "flags": {
        "nsfw": false,
        "religious": false,
        "political": false,
        "racist": false,
        "sexist": false,
        "explicit": false
    },
    "id": 232,
    "safe": true,
    "lang": "en"
}

您需要在查询其他 json 元素之前检查笑话类型。

import requests
import json

def getJoke():
  response = requests.get("https://v2.jokeapi.dev/joke/Any")
  json_data = json.loads(response.text)
  joke_type = json_data['type']
  if joke_type == 'single':
      joke = json_data['joke']
  elif joke_type == 'twopart':
    joke_setup = json_data['setup']
    joke_delivery = json_data['delivery']
    print (f'Joke Setup: {joke_setup} \nJoke Delivery: {joke_delivery}')
    # output
    Joke Setup: Why does Dr. Pepper come in a bottle?
    Joke Delivery: His wife is dead.


getJoke()

检查所有数据字段名称：

json_data = json.loads(response.text)
fields = json_data.keys()

然后检查joke或setup是否在字段名称内：

"joke" in fields
"setup" in fields
