python - 用Python重写Curl请求: Result Invalid Json

Question

我有这个可以工作的 curl ，它返回这个

curl -X POST \
https://login.smoobu.com/booking/checkApartmentAvailability \
-H 'Api-Key: xxxxx' \
-H 'cache-control: no-cache' \
-d '{
    "arrivalDate" : "2018-04-01",
    "departureDate":  "2019-12-03",
    "apartments": [126936, 127858, 126937],
    "customerId": 38484
}'

它返回这个

{
    "availableApartments": [
        127858
    ],
    "prices": [],
    "errorMessages": {
        "126936": {
            "errorCode": 405,
            "message": "The chosen day of departure is not available.",
            "departureDays": [
                "Sa"
            ]
        },
        "126937": {
            "errorCode": 405,
            "message": "The chosen day of departure is not available.",
            "departureDays": [
                "Sa"
            ]
        }
    }
}

我像这样用Python重写了它

In [1]: import requests

In [2]: headers = {'Api-Key': 'xxxx', 'cache-control': 'no-cache'}

In [8]: payload = {
...:     "arrivalDate" : "2018-04-01",
...:     "departureDate":  "2019-12-03",
...:     "apartments": [126936, 127858, 126937],
...:     "customerId": 38484
...: }

In [4]: r = requests.post("https://login.smoobu.com/booking/checkApartmentAvailability", data=payload, headers=headers)

In [5]: r
Out[5]: <Response [400]>

In [13]: r.content
Out[13]: b'{"title":"Error occurred","detail":"json is invalid"}'

我收到了无效 json 的响应，但我不确定为什么，因为我知道它的工作方式是它需要一个字典并将其转换为 json 请求。

要发送 JSON，您应该使用 json 参数:

r = requests.post("https://login.smoobu.com/booking/checkApartmentAvailability", json=payload, headers=headers)

如 docs 中所述:

r = requests.post(url, data=json.dumps(payload))
r = requests.post(url, json=payload)

Instead of encoding the dict yourself, you can also pass it directly using the json parameter (added in version 2.4.2) and it will be encoded automatically
