Parse data from multiple numbers in a list or slice - TypeError: list indices must be integers or slices, not str

Question

问题

我正在尝试从 freshdesk 获取所有支持工单的状态列表。

到目前为止，我已经能够 request.get 所有门票，但它包含的信息太多了。所以我试图只从 json 数据中提取“状态”。

如果我只想打印一张票的信息，会发生以下情况：

ticketresponse = requests.get(freshdeskticketsurl, auth = (freshdeskapi, freshdeskpassword))
ticket_json = ticketresponse.json()


ticket_str = json.dumps(ticket_json[0], indent=2)
print(ticket_str)

回复：

{
  "cc_emails": [],
  "fwd_emails": [],
  "reply_cc_emails": [],
  "ticket_cc_emails": [],
  "fr_escalated": false,
  "spam": false,
  "email_config_id": null,
  "group_id": 43000110950,
  "priority": 1,
  "requester_id": taking that out of this example,
  "responder_id": taking that out of this example,
  "source": 3,
  "company_id": taking that out of this example,
  "status": 5,
  "subject": "Receptiontv-min - can't use slide show in powerpoint",
  "association_type": null,
  "support_email": null,
  "to_emails": null,
  "product_id": null,
  "id": taking that out of this example,
  "type": "Trouble Ticket",
  "due_by": "2021-03-09T19:21:09Z",
  "fr_due_by": "2022-02-25T19:21:09Z",
  "is_escalated": false,
  "custom_fields": {},
  "created_at": "2021-03-02T19:21:09Z",
  "updated_at": "2021-03-02T19:21:16Z",
  "associated_tickets_count": null,
  "tags": []
}

我只想要“状态” 部分。我可以通过这样做只用一张票来做到这一点：

ticketresponse = requests.get(freshdeskticketsurl, auth = (freshdeskapi, freshdeskpassword))
ticket_json = ticketresponse.json()


ticket_str = json.dumps(ticket_json[0]['status'], indent=2)
print(ticket_str)

回复：

但是，我遇到问题的地方是尝试一次打印出所有票证的状态。我可以使用 ticket_str = json.dumps(ticket_json, indent=2) print(ticket_str)

一次打印出所有的票

但是，如果我尝试使用以下任何代码行来尝试获取所有状态，它会给我同样的错误：

ticket_str = json.dumps(ticket_json['status'], indent=2)

响应 TypeError: list indices must be integers or slices, not str

ticketslice = slice(0,20) ticket_str = json.dumps(ticket_json[ticketslice]['status'], indent=2)

响应 TypeError: list indices must be integers or slices, not str

如果有人有任何想法或有不同的想法，请告诉我。

感谢您的宝贵时间，

如果你想要所有你需要在响应数组上循环的状态，像这样：

for i in range(len(ticket_json)):
    ticket_str = json.dumps(ticket_json[i], indent=2)
    print(ticket_str['status'])
