无法正确读取json文件

Question

我想从联机https://api.myjson.com/bins/y2k4y读取json文件，并基于参数“ipv4”、“ipv6”进行打印。我已经用python编写了代码。它向我展示了这个错误。请建议我解决这个问题

Python代码

import requests
import json

# Method To Get REST Data In JSON Format
def getResponse(url,choice):

    response = requests.get(url)

    if(response.ok):
        jData = json.loads(response.content)
        if(choice=="deviceInfo"):
            print("working")
            deviceInformation(jData)
    else:
        print("NOT working")
        response.raise_for_status()


# Parses JSON Data To Find Switch Connected To H4
def deviceInformation(data):
    global switch
    global deviceMAC
    global hostPorts
    switchDPID = ""
    print ( data)
    for i in data:
        print ("i: ", i['ipv4'])


deviceInfo = "https://api.myjson.com/bins/y2k4y"
getResponse(deviceInfo,"deviceInfo")

错误

  File "E:/aaa/e.py", line 27, in deviceInformation
    print ("i: ", i['ipv4'])
TypeError: string indices must be integers

json文件https://api.myjson.com/bins/y2k4y

Answer 1

尝试使用for i in data['devices']:而不是for i in data:

Answer 2

jData是一个dict只有一个键devicesdevices包含您需要的所有其他信息

将for i in data更改为for i in data['devices']：

for i in data['devices']:
        print ("i: ", i['ipv4'])
        print ("i: ", i['ipv6'])
