Question

解析时，我得到以下答案：

{ 
    data: { 
        type: 'match',
        id: 'ae825686-8a74-4363-a1d1-402d5a4207d5',
        attributes: { 
            createdAt: '2018-11-20T17:06:52Z',
            titleId: 'bluehole-pubg',
            shardId: 'pc-ru',
            tags: null,
            seasonState: 'progress',
            duration: 1823,
            stats: null,
            gameMode: 'squad-fpp'
        },
    },  
    included: [ 
        { 
            type: 'participant',
            id: '0b1b8f78-bb3e-4c0a-9955-9fdf8e33e5b4',
            attributes: [Object] 
        },
        { 
            type: 'participant',
            id: '85e74b88-125b-4529-8c3f-fd76bd43b9aa',
            attributes: [Object] 
        },
        { 
            type: 'roster',
            id: '6db70dce-b056-4bed-8cc4-6521b83bea50',
            attributes: [Object],
            relationships: [Object] 
        },
        { 
            type: 'roster',
            id: 'a35db9ae-e559-4474-b922-784e3221f484',
            attributes: [Object],
            relationships: [Object] 
        }
    ]
}

我需要获取具有可能类型为“名册” 的数据，以及对象内容为属性，关系的数据。我该怎么做？我尝试提取数据数组console.log(included [0]);是从 type：'participant'类型中获取数据的。如此尝试console.log (included [{type: 'roster', relationship}]);是，我收到消息 undefined 请告诉我如何获取必要的数据。

Answer 1

使用Array.prototype.filter()

const response = { 
    data: { 
        type: 'match',
        id: 'ae825686-8a74-4363-a1d1-402d5a4207d5',
        attributes: { 
            createdAt: '2018-11-20T17:06:52Z',
            titleId: 'bluehole-pubg',
            shardId: 'pc-ru',
            tags: null,
            seasonState: 'progress',
            duration: 1823,
            stats: null,
            gameMode: 'squad-fpp'
        },
    },  
    included: [ 
        { 
            type: 'participant',
            id: '0b1b8f78-bb3e-4c0a-9955-9fdf8e33e5b4',
            attributes: [Object] 
        },
        { 
            type: 'participant',
            id: '85e74b88-125b-4529-8c3f-fd76bd43b9aa',
            attributes: [Object] 
        },
        { 
            type: 'roster',
            id: '6db70dce-b056-4bed-8cc4-6521b83bea50',
            attributes: [Object],
            relationships: [Object] 
        },
        { 
            type: 'roster',
            id: 'a35db9ae-e559-4474-b922-784e3221f484',
            attributes: [Object],
            relationships: [Object] 
        }
    ]
}

const arrayWithRoster = response.included.filter(item => item.type === 'roster');

console.log(arrayWithRoster);

我将创建两个数组并分别推送，如下所示：

let json = { 
    data: { 
        type: 'match',
        id: 'ae825686-8a74-4363-a1d1-402d5a4207d5',
        attributes: { 
            createdAt: '2018-11-20T17:06:52Z',
            titleId: 'bluehole-pubg',
            shardId: 'pc-ru',
            tags: null,
            seasonState: 'progress',
            duration: 1823,
            stats: null,
            gameMode: 'squad-fpp'
        },
    },  
    included: [ 
        { 
            type: 'participant',
            id: '0b1b8f78-bb3e-4c0a-9955-9fdf8e33e5b4',
            attributes: [Object] 
        },
        { 
            type: 'participant',
            id: '85e74b88-125b-4529-8c3f-fd76bd43b9aa',
            attributes: [Object] 
        },
        { 
            type: 'roster',
            id: '6db70dce-b056-4bed-8cc4-6521b83bea50',
            attributes: [Object],
            relationships: [Object] 
        },
        { 
            type: 'roster',
            id: 'a35db9ae-e559-4474-b922-784e3221f484',
            attributes: [Object],
            relationships: [Object] 
        }
    ]
}
let attributes = [];
let relationships = [];

let dataIneed = json.included.forEach(element => {
   if(element.type === 'roster'){
    attributes.push(element.attributes);
    relationships.push(element.relationships);
  }
})
