数据必须是对象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：来自服务器的错误

当尝试运行上面的代码时，我不断收到错误"additionalInfo必须是一个对象"。有人能帮我找出原因吗。我也尝试过传入json对象etc，但仍然不起作用。当additionalInfo字段为空时，它似乎只会给我一个2xx的响应，就像下面的代码一样

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获得TypeError: Object of type datetime is not JSON serializable，然后使用json参数直接传递数据。

查看差异，特别是additionalInfo数据的情况：

>>> 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。对于未来访问此网站的任何人，请点击此处：

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"
}
}
}
)

非常感谢所有帮助我的人
