数据必须是一个对象 python 请求库

Question

response = requests.post(
    url=bid_url,
    headers={'Authorization': my_api_key},
    data={
      "type": "open",
      "initiatorId": "ecc52cc1-a3e4-4037-a80f-62d3799645f4",
      "dateCreated": datetime.now(),
      "subjectId": "8a921487-859f-4931-8743-f69c38f91b25",
      "additionalInfo": {
        "someInfo": {
          "abcd":"123",
          "efgh":"456"
        }
      }
    }
)

错误： error from the server

在尝试运行上面的代码时，我一直收到错误 'additionalInfo must be an object'。有人可以帮我弄清楚为什么。我也尝试传入 json 对象等，但它仍然不起作用。当 additionalInfo 字段为空时，它似乎只给我一个 2xx 响应，如下面的代码

response = requests.post(
    url=bid_url,
    headers={'Authorization': my_api_key},
    data={
      "type": "open",
      "initiatorId": "ecc52cc1-a3e4-4037-a80f-62d3799645f4",
      "dateCreated": datetime.now(),
      "subjectId": "8a921487-859f-4931-8743-f69c38f91b25",
      "additionalInfo": {}
    }
)

Answer 1

您可以尝试先将 datetime.datetime.now() 转换为字符串以避免得到 TypeError: Object of type datetime is not JSON serializable，然后使用 json 参数直接传递数据。

看看区别，具体来说 additionalInfo 数据会发生什么：

>>> response = requests.post(
...     url='https://httpbin.org/post',
...     headers={'Authorization': 'abc'},
...     data={
...       "type": "open",
...       "initiatorId": "ecc52cc1-a3e4-4037-a80f-62d3799645f4",
...       "dateCreated": datetime.datetime.now().strftime("%Y-%m-%d %H:%M:%S"),
...       "subjectId": "8a921487-859f-4931-8743-f69c38f91b25",
...       "additionalInfo": {
...         "someInfo": {
...           "abcd":"123",
...           "efgh":"456"
...         }
...       }
...     }
... )
>>> print(response.text)

Answer 2

使用 strftime 帮助解决了我的问题，而且我不得不将数据类型从响应更改为 json。对于以后访问此网站的任何人，请前往：

response = requests.post(
    url=bid_url,
    headers={'Authorization': my_api_key},
    json={
      "type": "open",
      "initiatorId": "ecc52cc1-a3e4-4037-a80f-62d3799645f4",
      "dateCreated": datetime.now().strftime('%Y-%m-%dT%H:%M:%S.%f'),
      "subjectId": "8a921487-859f-4931-8743-f69c38f91b25",
      "additionalInfo": {
        "BidInfo": {
          "abcd":"123",
          "efgh":"456"
        }
      }
    }
)
