I want to create a post request like the following picture in python that return data as I received in a browser :

And cookie is as follow: For this, I have written the following code:

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)

But I don't receive the right information from the server.

CodePudding user response：

1. you need to post an application/json request so use the json parameter for requests.post()

2. the api you're communicating with seems to require some sort of authentication, try to transplant the session cookie with the cookies parameter

   data = {...}
   cookies = {"_session": "1ac[..]"}
   response = requests.post(url, json=data, cookies=cookies)

This will give you what you want:

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'])

Note: The session cookie used in this answer may expire. So, although it works now, it may not always work
