如何通过Amadeus API获取特定航班全舱位座位图数据

首先看你代码里的核心问题：
你的originDestinations数组里只有一个id为"1"的行程，但在cabinRestrictions里给BUSINESS舱设置了originDestinationIds: ["2"]，这个id不存在，所以这个舱位限制不会生效，自然搜不到商务舱的数据。

修正后的Flight Offer Search请求参数 #

把两个舱位限制的originDestinationIds都改成["1"]：

$data = [
    "currencyCode" => "USD",
    "originDestinations" => [
        [
            "id" => "1",
            "originLocationCode" => $originLocationCode,
            "destinationLocationCode" => $destinationLocationCode,
            "departureDateTimeRange" => [
                "date" => $departureDate,
                "time" => date('H:i:s', strtotime($departureTime)),
            ]
        ],
    ],
    "travelers" => [
        [
            "id" => "1",
            "travelerType" => "ADULT",
        ],
    ],
    "sources" => [
        "GDS",
    ],
    "searchCriteria" => [
        "flightFilters" => [
            "connectionRestriction" => [
                "maxNumberOfConnections" => 1,
            ],
            "cabinRestrictions" => [
                [
                    "cabin" => "ECONOMY",
                    "originDestinationIds" => ["1"],
                ],
                [
                    "cabin" => "BUSINESS",
                    "originDestinationIds" => ["1"],
                ],
                // 如需头等舱/超级经济舱，添加对应条目，注意枚举值正确性
                [
                    "cabin" => "FIRST",
                    "originDestinationIds" => ["1"],
                ],
                [
                    "cabin" => "PREMIUM_ECONOMY",
                    "originDestinationIds" => ["1"],
                ]
            ],
        ],
    ],
];

额外检查项 #

1. 确认Flight Offer Search返回结果包含多舱位offer
   调用Flight Offer Search后，检查返回的data数组里的每个flightOffers条目，查看travelerPricings[0].fareDetailsBySegment[0].cabin字段是否包含不同舱位值。如果搜索结果本身只有经济舱，说明对应航线/日期无其他舱位可用库存，或GDS源未提供该舱位数据。

2. 座位图API调用需传递所有目标舱位的flightOfferId
   每个flightOffer对应一个舱位，调用Seatmap API时，要把所有需要获取座位图的flightOfferId都传入请求体的flightOffers数组，示例：

   {
     "flightOffers": [
       { "flightOfferId": "offer-id-for-economy" },
       { "flightOfferId": "offer-id-for-business" }
     ]
   }
   

3. 验证舱位枚举值正确性
   Amadeus API的舱位枚举值需严格匹配官方定义：

   • 经济舱：ECONOMY
   • 超级经济舱：PREMIUM_ECONOMY（注意不是你写的Business_Economy）
   • 商务舱：BUSINESS
   • 头等舱：FIRST
