如何使用负载请求在 python 中创建 post 请求？

Question

我想创建一个 post 请求，如下图 python 中的 return 我在浏览器中收到的数据：

cookie如下：为此，我编写了以下代码：

import requests

url = "https://flight-api-v1.utravs.com/Flight/statistic/FlightPriceStatistics"
data = {
    "minimumPriceStatisticRequest": {
        "$id": 1,
        "availabilityRequest": {
            "$id": 2,
            "segments": {
                "$id": 3,
                "$values": [
                    {
                        "$id": 4,
                        "destination": "KIH-Kish-all",
                        "origin": "THR-Tehran-all",
                        "departureDateTime": "2021-12-02T00:00:00.000Z",
                        "uniqueIndex": 0
                    }
                ]
            },
            "passengers": {
                "$id": 5,
                "$values": [
                    {
                        "$id": 6,
                        "type": 1,
                        "quantity": 1,
                        "optionalServices": {
                            "$id": 7,
                            "$values": []
                        }
                    }
                ]
            },
            "travelDetails": {
                "$id": 8,
                "cabinType": 1,
                "airTripType": 1,
                "stopQuantityType": 3,
                "pricingSourceType": 3
            },
            "availabilityType": 0
        },
        "minRange": 10,
        "maxRange": 10
    }
}
x = requests.post(url, data=data)
print(x.text)

但是我没有从服务器收到正确的信息。

Answer 1

您需要 post 一个 application/json 请求，因此请为 requests.post()
使用 json 参数
您正在与之通信的 api 似乎需要某种身份验证，请尝试使用 cookies 参数
移植会话 cookie
```
data = {...}
cookies = {"_session": "1ac[..]"}
response = requests.post(url, json=data, cookies=cookies)
```

Answer 2

这会给你想要的：

import requests

url = "https://flight-api-v1.utravs.com/Flight/statistic/FlightPriceStatistics"
data = {
    "minimumPriceStatisticRequest": {
        "$id": 1,
        "availabilityRequest": {
            "$id": 2,
            "segments": {
                "$id": 3,
                "$values": [
                    {
                        "$id": 4,
                        "destination": "KIH-Kish-all",
                        "origin": "THR-Tehran-all",
                        "departureDateTime": "2021-12-02T00:00:00.000Z",
                        "uniqueIndex": 0
                    }
                ]
            },
            "passengers": {
                "$id": 5,
                "$values": [
                    {
                        "$id": 6,
                        "type": 1,
                        "quantity": 1,
                        "optionalServices": {
                            "$id": 7,
                            "$values": []
                        }
                    }
                ]
            },
            "travelDetails": {
                "$id": 8,
                "cabinType": 1,
                "airTripType": 1,
                "stopQuantityType": 3,
                "pricingSourceType": 3
            },
            "availabilityType": 0
        },
        "minRange": 10,
        "maxRange": 10
    }
}
with requests.Session() as session:
    cookies = {"_session": "1acda9e8-3051-47bb-bddf-9d68553ebbee"}
    headers = {"Accept": "application/json"}
    (x := session.post(url, json=data, cookies=cookies, headers=headers)).raise_for_status()
    print(x.json()['Result'])

注意：此回答中使用的会话 cookie 可能会过期。所以，虽然它现在有效，但可能并不总是有效
