Graphql API 响应返回意外数据

Question

我正在尝试使用 graphql API 调用从 expedia.com 获取酒店评论，我有 graphql 查询及其变量

当我尝试使用 postman 时，它返回正确的结果，但是当我尝试使用 cURL php 时，它什么也没返回

这是我的网址

https://www.expedia.com/graphql

这是我发布请求的行数据

{
  "operationName": "Reviews",
  "query": "query Reviews($context: ContextInput!, $propertyId: String!, $pagination: PaginationInput!, $sortBy: PropertyReviewSort!, $filters: PropertyReviewFiltersInput!) {propertyInfo(propertyId: $propertyId,  context: $context) {reviewInfo(sortBy: $sortBy, pagination: $pagination, filters: $filters) { summary { superlative totalCount { raw formatted } reviewCountLocalized averageOverallRating { raw formatted } cleanliness { raw formatted } serviceAndStaff { raw formatted } amenityScore { raw formatted } hotelCondition { raw formatted } cleanlinessPercent cleanlinessOverMax serviceAndStaffPercent serviceAndStaffOverMax amenityScorePercent amenityScoreOverMax hotelConditionPercent hotelConditionOverMax ratingCounts { count { formatted raw } percent rating } lastIndex reviewDisclaimer } reviews { id ratingOverall superlative submissionTime { raw } title text locale author userLocation stayDuration helpfulReviewVotes negativeRemarks positiveRemarks locationRemarks photos { description url } managementResponses { id date displayLocale userNickname response } travelers themes { icon { id description } label } } sortAndFilter { sortAndFilter { name label options { label isSelected optionValue } } } } } }",
  "variables": {
    "context": {
      "siteId": 1,
      "locale": "en_US",
      "currency": "USD",
      "device": {
        "type": "DESKTOP"
      },
      "identity": {
        "duaid": "986e9653-0e36-413f-8fff-19bd7bddbe9b",
        "expUserId": "-1",
        "tuid": "-1",
        "authState": "ANONYMOUS"
      },
      "debugContext": {
        "abacusOverrides": [

        ],
        "alterMode": "RELEASED"
      }
    },
    "propertyId": "1173275",
    "sortBy": "NEWEST_TO_OLDEST",
    "filters": {
      "includeRecentReviews": false,
      "includeRatingsOnlyReviews": true
    },
    "pagination": {
      "startingIndex": 10,
      "size": 10
    }
  }
}

这是我的 php cURL 代码

<?php

$curl = curl_init();

curl_setopt_array($curl, array(
  CURLOPT_URL => "https://www.expedia.com/graphql",
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_ENCODING => "",
  CURLOPT_MAXREDIRS => 10,

  ),
));

$response = curl_exec($curl);
$err = curl_error($curl);

curl_close($curl);

if ($err) {
  echo "cURL Error #:" . $err;
} else {
  echo $response;
}

我也尝试使用 node js 请求调用，但它在缓冲区中返回数据并且该数据无法转换为 json 格式

请帮我解决这个问题

您的 GraphQL 查询出现错误，我不确定具体是什么，但我使用了 GraphQL Playground 并选择了“Copy Curl”并将查询粘贴到您的代码中，这对我有用：

<?php

$curl = curl_init();

curl_setopt_array($curl, array(
