如何从Airbnb API获取JSON响应？遇400无效密钥错误求助

问题描述 #

尝试用Python调用Airbnb的StaysPdpSections接口获取房源数据，但返回400错误，错误响应显示：

{
    "errors": [
        {
            "message": "Response not successful: Received status code 400",
            "locations": [{"line": 1,"column": 1}],
            "path": [],
            "extensions": {
                "response": {
                    "statusCode": 400,
                    "body": {
                        "error_code": 400,
                        "error": "invalid_key",
                        "error_message": "Invalid API key."
                    }
                },
                "code": "Bad Request"
            }
        }
    ],
    "data": null
}

调用代码如下：

import json
from urllib.request import urlopen

def fetch_airbnb_data():
    api_url = "https://www.airbnb.co.uk/api/v3/StaysPdpSections/3bcbe9ee20da9daa6722934f0b54ef68db41699d179e698c3aeab4ec30a964cb?operationName=StaysPdpSections&locale=en-GB&currency=GBP&variables=%7B%22id%22%3A%22U3RheUxpc3Rpbmc6MTAyNzQ1NzkyNDI2OTA2NDk4OQ%3D%3D%22%2C%22pdpSectionsRequest%22%3A%7B%22adults%22%3A%221%22%2C%22amenityFilters%22%3Anull%2C%22bypassTargetings%22%3Afalse%2C%22categoryTag%22%3Anull%2C%22children%22%3Anull%2C%22disasterId%22%3Anull%2C%22discountedGuestFeeVersion%22%3Anull%2C%22displayExtensions%22%3Anull%2C%22federatedSearchId%22%3Anull%2C%22forceBoostPriorityMessageType%22%3Anull%2C%22hostPreview%22%3Afalse%2C%22infants%22%3Anull%2C%22interactionType%22%3Anull%2C%22layouts%22%3A%5B%22SIDEBAR%22%2C%22SINGLE_COLUMN%22%5D%2C%22pets%22%3A0%2C%22pdpTypeOverride%22%3Anull%2C%22photoId%22%3Anull%2C%22preview%22%3Afalse%2C%22previousStateCheckIn%22%3Anull%2C%22previousStateCheckOut%22%3Anull%2C%22priceDropSource%22%3Anull%2C%22privateBooking%22%3Afalse%2C%22promotionUuid%22%3Anull%2C%22relaxedAmenityIds%22%3Anull%2C%22searchId%22%3Anull%2C%22selectedCancellationPolicyId%22%3Anull%2C%22selectedRatePlanId%22%3Anull%2C%22splitStays%22%3Anull%2C%22staysBookingMigrationEnabled%22%3Afalse%2C%22translateUgc%22%3Anull%2C%22useNewSectionWrapperApi%22%3Afalse%2C%22sectionIds%22%3Anull%2C%22checkIn%22%3Anull%2C%22checkOut%22%3Anull%2C%22p3ImpressionId%22%3A%22p3_1729488926_P3eUXvpmVbFyX_Cq%22%7D%7D&extensions=%7B%22persistedQuery%22%3A%7B%22version%22%3A1%2C%22sha256Hash%22%3A%223bcbe9ee20da9daa6722934f0b54ef68db41699d179e698c3aeab4ec30a964cb%22%7D%7D"
    
    try:
        jsonurl = urlopen(api_url)
        data = json.loads(jsonurl.read())
        print(json.dumps(data, indent=4))
    except Exception as e:
        print(f"Error fetching data: {e}")

fetch_airbnb_data()

问题原因 #

你调用的是Airbnb网页端使用的私有GraphQL接口，这类接口需要携带合法的验证信息（如API密钥、Cookie、请求头等）才能访问。直接裸请求没有任何验证标识，会被服务器判定为无效请求，返回"invalid_key"错误。

解决方法 #

1. 改用官方公开API（推荐商业场景） #

如果是商业用途，需申请Airbnb官方的Partner API，获取合法的API密钥后，按照官方文档要求构造请求。通常需要在请求头中添加授权字段，例如：

headers = {
    'Authorization': 'Bearer YOUR_OFFICIAL_API_KEY',
    'Content-Type': 'application/json'
}

2. 模拟浏览器请求（仅用于个人学习测试） #

如果只是个人学习，可通过模拟浏览器的请求头绕过基础验证。至少需要添加User-Agent字段模拟真实浏览器，若仍失败，可从浏览器开发者工具中复制网页请求的Cookie、X-Airbnb-API-Key等字段补充到请求头：

import json
import urllib.request

    api_url = "https://www.airbnb.co.uk/api/v3/StaysPdpSections/3bcbe9ee20da9daa6722934f0b54ef68db41699d179e698c3aeab4ec30a964cb?operationName=StaysPdpSections&locale=en-GB&currency=GBP&variables=%7B%22id%22%3A%22U3RheUxpc3Rpbmc6MTAyNzQ1NzkyNDI2OTA2NDk4OQ%3D%3D%22%2C%22pdpSectionsRequest%22%3A%7B%22adults%22%3A%221%22%2C%22amenityFilters%22%3Anull%2C%22bypassTargetings%22%3Afalse%2C%22categoryTag%22%3Anull%2C%22children%22%3Anull%2C%22disasterId%22%3Anull%2C%22discountedGuestFeeVersion%22%3Anull%2C%22displayExtensions%22%3Anull%2C%22federatedSearchId%22%3Anull%2C%22forceBoostPriorityMessageType%22%3Anull%2C%22hostPreview%22%3Afalse%2C%22infants%22%3Anull%2C%22interactionType%22%3Anull%2C%22layouts%22%3A%5B%22SIDEBAR%22%2C%22SINGLE_COLUMN%22%5D%2C%22pets%22%3A0%2C%22pdpTypeOverride%22%3Anull%2C%22photoId%22%3Anull%2C%22preview%22%3Afalse%2C%22previousStateCheckIn%22%3Anull%2C%22previousStateCheckOut%22%3Anull%2C%22priceDropSource%22%3Anull%2C%22privateBooking%22%3Afalse%2C%22promotionUuid%22%3Anull%2C%22relaxedAmenityIds%22%3Anull%2C%22searchId%22%3Anull%2C%22selectedCancellationPolicyId%22%3Anull%2C%22selectedRatePlanId%22%3Anull%2C%22splitStays%22%3Anull%2C%22staysBookingMigrationEnabled%22%3Afalse%2C%22translateUgc%22%3Anull%2C%22useNewSectionWrapperApi%22%3Afalse%2C%22sectionIds%22%3Anull%2C%22checkIn%22%3Anull%2C%22checkOut%22%3Anull%2C%22p3ImpressionId%22%3A%22p3_1729488926_P3eUXvpmVbFyX_Cq%22%7D%7D&extensions=%7B%22persistedQuery%22%3A%7B%22version%22%3A1%2C%22sha256Hash%22%3A%223bcbe9ee20da9daa6722934f0b54ef68db41699d179e698c3aeab4ec30a964cb%22%7D%7D"
    
    headers = {
        'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/129.0.0.0 Safari/537.36'

    }
    
    try:
        req = urllib.request.Request(api_url, headers=headers)
        jsonurl = urllib.request.urlopen(req)
        data = json.loads(jsonurl.read())
        print(json.dumps(data, indent=4))
    except Exception as e:
        print(f"Error fetching data: {e}")

注意事项 #

• 私有接口随时可能变更，且未经授权使用可能违反Airbnb服务条款，商业场景务必使用官方API。
• 模拟浏览器请求时，Cookie等验证字段可能会过期，需要定期更新。
