尝试使用Python通过API访问数据时出错

Question

尝试使用API访问有关服务器存储的详细信息时出错。我想提取json中的备份状态，即state：

{
   "storage": {
      "access": "private",
      "backup_rule": {},
      "backups": {
         "backup": []
      },
      "license": 0,
      "part_of_plan": "",
      "servers": {
         "server": [
            ""
         ]
      },
      "size": ,
      "state": "online",
      "tier": "",
      "title": "",
      "type": "",
      "uuid": "",
      "zone": ""
   }
}

当我执行此代码时：

bkpdet = requests.get('https://fffff.com/1.2/storage/08475', auth=HTTPBasicAuth('login', 'pass'))
bkpdet_json = bkpdet.json()
datastg = bkpdet.json()
print(datastg)
for sts in datastg['storage']:
    bkpsts = sts['state']
    print(bkpsts)

我得到这个错误：

Traceback (most recent call last):
  File "<stdin>", line 2, in <module>
TypeError: string indices must be integers

如何访问状态*？ 整体思路是在最后使用以下代码获取有关状态的信息：

if bkpsts == "online":
    print('Backup has been created.')
else bkpsts == "backuping":
    print('Backup creation is in progress.')
else:
    print(bkpdet.status_code)

我一直在找，但还是找不到这里出了什么问题

正如@MarkMeyer所建议的，我修改了如下代码：

bkpdet = requests.get('https://fffff.com/1.2/storage/08475', auth=HTTPBasicAuth('login', 'pass'))
bkpdet_json = bkpdet.json()
datastg = bkpdet.json()
bkpsts = datastg['storage']['state']
print(bkpsts)

它工作得很好
