GraphQL 中的布尔运算

  • 772

告诉我，谁使用过 GraphQL，我想从SpaceX API提出这样的请求：

{
  ships(find: {name: "", home_port: "'Fort Lauderdale' || 'Port of Los Angeles'"}) {
    name
    home_port
    type
    id
  }
}

有必要找到拥有一个或另一个港口的所有船只。但||它不起作用，只有一条简单的线路起作用，一个端口。有谁知道在 GraphQL 中一次这样做的方法？没有 JavaScript

    first例如，您可以这样做：（second这些是我想出的随机名称）

    {
  first: ships(find: {name: "", home_port: "Fort Lauderdale"}) {
    name
    home_port
    type
    id
  }
  second: ships(find: {name: "", home_port: "Port of Los Angeles"}) {
    name
    home_port
    type
    id
  }
}

    答案将是：

    {
  "data": {
    "first": [
      {
        "name": "Hollywood",
        "home_port": "Fort Lauderdale",
        "type": "Tug",
        "id": "HOLLYWOOD"
      }
    ],
    "second": [
      {
        "name": "American Champion",
        "home_port": "Port of Los Angeles",
        "type": "Tug",
        "id": "AMERICANCHAMPION"
      },
      {
        "name": "Just Read The Instructions 2",
        "home_port": "Port of Los Angeles",
        "type": "Barge",
        "id": "JRTI-2"
      },
      {
        "name": "NRC Quest",
        "home_port": "Port of Los Angeles",
        "type": "Cargo",
        "id": "NRCQUEST"
      },
      {
        "name": "Pacific Warrior",
        "home_port": "Port of Los Angeles",
        "type": "Tug",
        "id": "PACIFICWARRIOR"
      },
      {
        "name": "Pacific Freeedom",
        "home_port": "Port of Los Angeles",
        "type": "Tug",
        "id": "PACIFICFREEDOM"
      },
      {
        "name": "Betty R Gambarella",
        "home_port": "Port of Los Angeles",
        "type": "Tug",
        "id": "BETTYRGAMBARELLA"
      },
      {
        "name": "American Islander",
        "home_port": "Port of Los Angeles",
        "type": "Cargo",
        "id": "AMERICANISLANDER"
      },
      {
        "name": "Kelly C",
        "home_port": "Port of Los Angeles",
        "type": "Tug",
        "id": "KELLYC"
      },
      {
        "name": "American Spirit",
        "home_port": "Port of Los Angeles",
        "type": "Cargo",
        "id": "AMERICANSPIRIT"
      }
    ]
  }
}
