Question

我似乎遇到了一个奇怪的阻止程序，试图访问JSON数据结构中的一些数据项。

我需要在JSON中迭代数据数组中的项目，但无法确定如何访问它们。

我试过这个：

import json
from pprint import pprint

file = 'data.json'

with open(file) as data_file:
    data = json.load(data_file)

for host in data:
    print host["host"]

    for proto in host["protocols"]:
        print proto

这让我得到了我的协议版本，但我无法找到如何获取数据数组中的项目。

[
  {
    "host": "192.168.0.1",
    "port": 443,
    "protocols": {
      "v1": {
        "data": ["12345","54354334534253245342"],
        "tag": "abc"
      },
      "v2": {
        "data": ["45678"],
        "tag": "xyz"
      }
    },
    "processed": false
  },
  {
    "host": "192.168.0.3",
    "port": 443,
    "protocols": {
      "v1": {
        "data": ["12345","43434","543543543"],
        "tag": "abc"
      },
      "v2": {
        "data": ["45678"],
        "tag": "xyz"
      },
      "v3": {
        "data": ["910111"],
        "tag": "ttt"
      }
    },
    "processed": false
  }
]

Protocols是一个字典，所以你需要以不同的方式迭代它：

import json
from pprint import pprint

file = 'data.json'

with open(file) as data_file:
    data = json.load(data_file)

for host in data:
    print host["host"]

    for version, proto in host["protocols"].iteritems():
        print version
        print proto
        print proto["data"]

JSON迭代数组
