Question

我正在创建一个Python脚本来解析来自https://vulners.com/api/v3/search/stats/

的JSON响应

我的.py中有以下代码：

import json
import requests

response = requests.get('https://vulners.com/api/v3/search/stats/')
vuln_set = json.loads(response.text)

vuln_type = vuln_set['data']['type_results']
vuln_bulletinfamily = vuln_set['data']['type_results'][vuln_type]['bulletinFamily']
vuln_name = vuln_set['data']['type_results'][vuln_type]['displayName']

print("Type: " + vuln_type)
print("Bulletin Family: " + vuln_bulletinfamily)
print("Name: " + vuln_name)

我需要获取vuln_type以及子信息（vuln_bulletinfamily＆amp; vuln_name） JSON响应的摘录：

"data": {
"type_results": {
  "aix": {
    "lastUpdated": [],
    "bulletinFamily": "unix",
    "displayName": "IBM AIX",
    "lastrun": "2017-09-14T14:04:56",
    "count": 110,
    "workTime": "0:00:10.983795"
  },
  "akamaiblog": {
    "lastUpdated": [],
    "bulletinFamily": "blog",
    "displayName": "Akamai Blog",
    "lastrun": "2017-09-14T10:38:52",
    "count": 1463,
    "workTime": "0:00:00.358691"
  },
  "amazon": {
    "lastUpdated": [],
    "bulletinFamily": "unix",
    "displayName": "Amazon Linux AMI",
    "lastrun": "2017-09-14T14:17:40",
    "count": 889,
    "workTime": "0:00:01.839594"
  },

我收到TypeError的错误：unhashable类型：＆＃39; dict＆＃39;

回溯：

Traceback (most recent call last):
File "test.py", line 9, in <module>
vuln_bulletinfamily = vuln_set['data']['type_results'][vuln_type]['bulletinFamily']
TypeError: unhashable type: 'dict'

Answer 1

在追溯线，下一行和第一个打印行中，您尝试使用也是字典的键访问字典type_results和vuln_type。您需要循环键，例如： -

import json
import requests

response = requests.get('https://vulners.com/api/v3/search/stats/')
vuln_set = json.loads(response.text)

vuln_type = vuln_set['data']['type_results']
for k in vuln_type :
    vuln_bulletinfamily = vuln_set['data']['type_results'][k]['bulletinFamily']
    vuln_name = vuln_set['data']['type_results'][k]['displayName']

    print("Type: " + k)
    print("Bulletin Family: " + vuln_bulletinfamily)
    print("Name: " + vuln_name)

Answer 2

vuln_set = json.loads(response.text) vs response.json()

Python JSON不可用类型：＆＃39; dict＆＃39;
