我想从这部分：

"subtasks": [
                    {
                        "fields": {
                            "issuetype": {
                                "avatarId": 10316,
                                "description": "The sub-task of the issue",
                                "iconUrl": "https://jira.corp.company.com/secure/viewavatar?size=xsmall&avatarId=10316&avatarType=issuetype",
                                "id": "10101",
                                "name": "Sub-task",
                                "self": "https://jira.corp.company.com/rest/api/2/issuetype/10101",
                                "subtask": true
                            },
                            "priority": {
                                "iconUrl": "https://jira.corp.company.com/images/icons/priorities/medium.svg",
                                "id": "3",
                                "name": "Medium",
                                "self": "https://jira.corp.company.com/rest/api/2/priority/3"
                            },
                            "status": {
                                "description": "",
                                "iconUrl": "https://jira.corp.company.com/",
                                "id": "10000",
                                "name": "Backlog",
                                "self": "https://jira.corp.company.com/rest/api/2/status/10000",
                                "statusCategory": {
                                    "colorName": "blue-gray",
                                    "id": 2,
                                    "key": "new",
                                    "name": "To Do",
                                    "self": "https://jira.corp.company.com/rest/api/2/statuscategory/2"
                                }
                            },
                            "summary": "Remove user account in Local AD"
                            },

提取"Remove user account in Local AD"（摘要字段）

到目前为止，我有这个代码：

data = json.load(open(1.json))


for issue in data['issues']:
   print issue['fields']['subtasks']

以及上面的获取部分，如何仅获取汇总值？

如果我添加：

for issue in data['issues']:
   print issue['fields']['subtasks']['summary']

我明白了：

 print issue['fields']['subtasks']['summary']
TypeError: list indices must be integers, not str

与：

    for i in range (0, len (data['issues'])):
       print data['issues']['fields']['subtasks'][i]['fields']['summary']
TypeError: list indices must be integers, not str

【问题讨论】：

子任务是一个列表，遍历它并为列表中的每个项目打印item['summary']。虽然从这个例子来看，它看起来是item['fields']['summary']
item['fields']['summary'] 提供主要问题的摘要，而不是子任务摘要（删除本地 AD 中的用户帐户）

标签： python json

【解决方案1】：

啊，子任务是关键，但是item是一个列表！

所以你要找的是issue['fields']['subtasks'][0]['summary']。

【讨论】：

print issue['fields']['subtasks'][0]['summary'] KeyError: 'summary'
我仔细看了看：试试print issue['fields']['subtasks'][0]['fields']['summary'] 它应该可以工作
已经试过了：print issue['fields']['subtasks'][0]['fields']['summary'] IndexError: list index out of range
我认为使用 .get() issue.get('fields').get(...) 方法更好
print issue.get("fields").get("subtasks").get("summary") AttributeError: 'list' object has no attribute 'get'

【解决方案2】：

感谢@nawarkhede

for issue in data['issues']:
  for subtask in issue['fields']['subtasks']:
    if subtask['fields']['summary'] == 'The specified directory could not be found in the specified region.-traider':
      print subtask['fields']['summary']
