从 JSON 数据访问特定数据 (Python)

Question

I am new to JSON in Python (forgive me if I word something incorrectly) and I am trying to parse JSON information I get from an API. 我成功获得了 API 信息，但是当我尝试提取我需要的信息时（特别是变量信息中的“名称”值）。 我似乎找不到任何有关如何访问它的信息。 代码如下：

# Importing JSON handling library for parsing GET request using requests library
import json
import requests
import ast
import collections

# API Endpoint
url = "https://fnbr.co/api/shop"

# API key
key = "" # key is usually here

# Defining Parameters
headers = {"x-api-key":key}

# Sending GET request
req = requests.get(url = url, headers = headers)



info = req.json()
info = info['data']['featured']
print(info)

和 output：

我特别需要所有“名称”值属性，例如“死侍装备包”，但我不确定如何。 如果我尝试访问位置 info['data']['featured']['name'] 位置，它会给我一个错误。 此外，每天可能会有不同数量的“名称”值，因此我需要一种方法来返回所有这些值的属性。

Answer 1

因此，您需要注意两种类型的对象。

dict ：当您加载 JSON 时，它会存储为字典 object。 Dict 对象允许您通过键访问值，就像您在此处所做的那样 -> info['data']['featured']

list : print(info) 显示 'info' 是一个事物列表。 您可以通过方括号 [] 或仅通过调用print(type(info))来判断。 订购了一个列表，以便访问列表中第一个 object 的名称，您会说info[0]['name'] 。

要连续获取列表中的所有对象，可以使用 for 循环：

for x in info: print(x['name'])你可以随意命名'x'。 该循环只是说“对于此列表中的每个 object，执行以下操作”
