如何在Python中从此JSON获取“url”变量

Question

如何从这个JSON字符串打印出“url”的内容

[{"breeds":[],"id":"bkv","url":"https://cdn2.thecatapi.com/images/bkv.jpg","width":800,"height":600}]

我只想在python控制台中打印它。如果重要的话，该JSON来自https://api.thecatapi.com/v1/images/search

    response = requests.get('https://api.thecatapi.com/v1/images/search')
x = response.json()
json_obj = json.loads(x)
for i in json_obj:
    print(i["url"])

Answer 1

假设JSON字符串中有多个JSON元素：

import json
json_string = '[{"breeds":[],"id":"bkv","url":"https://cdn2.thecatapi.com/images/bkv.jpg","width":800,"height":600}]'
json_obj = json.loads(json_string)
for i in json_obj:
    print(i["url"])

如果希望直接从URL接收JSON，可以直接执行以下操作：

import requests
for i in requests.get("https://api.thecatapi.com/v1/images/search").json():
    print(i["url"])
