POST请求在POSTMAN上工作，但在Python和cURL中不工作

我正试图从一家酒店获取信息。他们有公共API来获取这些信息。如果我们检查正确，我们将得到API。当我通过邮递员发出POST请求时，它以正确的格式提供数据，但在我从邮递员粘贴到Jupyter笔记本时代码相同，得到403错误。我尝试了cURL和python3

我认为有效负载项的正确格式有问题

这是我从POSTMAN获得的Python请求模块代码-

import requests

url = "https://www.homeaway.co.uk/pdp/graphql"

payload = "{\"query\":\"\\n    query priceDetails($createTravelerCheckoutRequest: CreateTravelerCheckoutRequest) {\\n        priceDetails(createTravelerCheckoutRequest: $createTravelerCheckoutRequest) {\\n            notes {\\n                description\\n            }\\n            totals {\\n                title\\n                amount\\n                tooltip\\n                subItems {\\n                    title\\n                }\\n            }\\n            checkoutUrl\\n            instantBooking\\n            dueNow {\\n                title\\n                amount\\n                tooltips {\\n                    title\\n                    amount\\n                    tooltip\\n                }\\n            }\\n            payments {\\n                title\\n                amount\\n                paidText\\n                infoText\\n                status\\n                viewUrl\\n            }\\n            averageNightlies {\\n                perNightCost {\\n                    currency\\n                    amount\\n                    localized\\n                }\\n                type\\n            }\\n            edapEventJson\\n            edapQuoteSuccess\\n            edapPriceQuotePresented\\n            lineItems {\\n                title\\n                amount\\n                mixedCurrencyDisclaimer\\n                type\\n                tooltip\\n                subItems {\\n                    title\\n                    amount\\n                    type\\n                    tooltip\\n                }\\n            }\\n        }\\n    }\\n\",\"variables\":{\"createTravelerCheckoutRequest\":{\"unit\":\"/units/0001/06a12c46-a89b-4620-86f2-7007e2955d90\",\"arrivalDate\":\"2020-03-13\",\"departureDate\":\"2020-03-18\",\"children\":0,\"adults\":2,\"pets\":0,\"listingRef\":\"611.10570866.5597723\",\"currency\":\"USD\"}},\"operation\":\"graphql_get_pricing_quote\"}"

请求类型-POST

请求URL-

邮递员的回应--

来自Python请求模块的请求和响应--

谁能帮我解释一下为什么会发生这种事？？如何解决这个问题

---

检查页面的链接是-。请参考图ql请求。

您的有效负载可能正在发挥作用。您可以以原始格式发布有效负载（不带\n）。@VishalSingh这里是不带（\n）-``的有效负载，试试看是否有区别：

response=requests.request（“post”，url，json=json.loads（payload），headers=headers）

。记住导入json模块。这将正确地将请求作为JSON有效负载发送。@MarcSances对

JSON.loads（）

方法没有任何运气。当我用单引号发送负载参数时出错，但当我在Postman中使用双引号时，工作正常…在JSON.loads（）之后获取此错误代码400，``{“statusCode”：400，“error”：“Bad Request”，“message”：“Invalid Request payload JSON format”}```
