从python中的json格式获取特定密钥

Question

我正在尝试从这个json文件中获取一个特定的密钥vulnerabilityID和vulnerabilitySoln。这是向json脚本底部的方向。

{
   "vulnerabilities": [
      {
         "labels": [
            {
               "labelKey": "com.acme.image.source",
               "labelValue": "http://github.com/base-image.git"
            },
            {
               "labelKey": "BA",
               "labelValue": "abc"
            },
            {
               "labelKey": "OwnerContact",
               "labelValue": "john.doe@gmail.com"
            }
         ],
         "repositoryDigest": [
            {
               "digest": "9089",
               "repository": "frost/micro",
               "registry": "artifactory.acme.com"
            }
         ],
         "artifactorySha": "4324",
         "imageID": "er34342",
         "createdTimestamp": "2022-10-17",
         "engineeringEID": "afd343",
         "vulnerabilities": [
            {
               "test1": "12444",
               "test2": "433w",
               "vulnerabilityID": "12345",
               "vulnerabilitySoln": "http://website.com"
            }
         ]
      }
   ]
}

下面是我尝试的代码

import json
import smtplib


with open("dummy.json") as json_file:
    data = json.load(json_file)

def vulnData():
    for i in data["vulnerabilities"]:
        vulnID = (i["vulnerabilities"]["vulnerabilityID"])
        vulnSoln = (i["vulnerabilities"]["vulnerabilitySoln"])
        print(vulnID, vulnSoln)

vulnData()

这是我得到的错误输出-- TypeError:列表索引必须是整数或切片，而不是str。请建议我如何获得特定的价值。

    vulnID = (i["vulnerabilities"]["vulnerabilityID"])
TypeError: list indices must be integers or slices, not str

Answer 1

其中还有两个层次的清单：

def vulnData():
    for i in data["vulnerabilities"]:
        vuln = i["vulnerabilities"][0]
        vulnID = vuln["vulnerabilityID"]
        vulnSoln = vuln["vulnerabilitySoln"])
        print(vulnID, vulnSoln)
