使用python在JSON文件中搜索特定密钥

JSON文件：

我可以提取TECH-XXX

#!/usr/bin/python
import sys
import json
sys.stdout = open('output.txt','wt')

datapath = sys.argv[1]
data = json.load(open(datapath))

for issue in data['issues']:
        if len(issue['fields']['subtasks']) == 0:
                print(issue['key'])

针对没有子任务的每个问题（TECH-729 TECH-731）我想从中提取TECH

                    "avatarUrls": {
                        "16x16": "https://jira.corp.company.com/secure/projectavatar?size=xsmall&pid=10001&avatarId=10201",

                },

和customfield_10107.id

我尝试了

打印（问题['customfield_10107']['id']）

并获得了成功

./tasks1.py 1.json
Traceback (most recent call last):
  File "./tasks1.py", line 11, in <module>
    print(issue['customfield_10107']['id'])
KeyError: 'customfield_10107'

/tasks1.py 1.json
回溯（最近一次呼叫最后一次）：
文件“/tasks1.py”，第11行，在
打印（问题['customfield_10107']['id']
KeyError:'customfield_10107'

键

存在于

问题下

和

自定义字段_10107

存在于

问题['fields']

：

for issue in response["issues"]:
    # For issues without subtasks
    if len(issue['fields']['subtasks']) == 0:
        # Print custom field id
        if 'customfield_10107' in issue['fields']:
            custom_field = issue['fields']['customfield_10107']
            print custom_field['id']

        # Print key
        if 'key' in issue:
            print issue['key']
