javascript - 通过 JSONAPI-Serializer 进行反序列化时遇到奇怪的问题

Question

如果我喜欢这个

var JSONAPIDeserializer = require('jsonapi-serializer').Deserializer;

var UserDeserialize = new JSONAPIDeserializer('id');
UserDeserialize.deserialize({ data: [ { type: 'ids', id: '1' }, { type: 'ids', id: '2' } ] })
.then(a => console.log(a))

我能够获得所需的反序列化输出

[ { id: '1' }, { id: '2' } ]

但是如果我创建一个序列化数据变量并尝试像这样序列化相同的变量

var JSONAPIDeserializer = require('jsonapi-serializer').Deserializer;

var test = "{ data: [ { type: 'ids', id: '1' }, { type: 'ids', id: '2' } ] }"
var UserDeserialize = new JSONAPIDeserializer('id');
UserDeserialize.deserialize(test)
.then(a => console.log(a))

我收到这样的错误:-

/Users/acid/node_js/node_modules/jsonapi-serializer/lib/deserializer-utils.js:70
    var dest = keyForAttribute(from.attributes || {});
                                   ^

    at run (bootstrap_node.js:425:7)
    at startup (bootstrap_node.js:146:9)

我该如何纠正这个问题？

Answer 1

替换...

var test = "{ data: [ { type: 'ids', id: '1' }, { type: 'ids', id: '2' } ] }"
UserDeserialize.deserialize(test)

...与:

var test = '{"data":[{"type":"ids","id":"1"},{"type":"ids","id":"2"}]}'
UserDeserialize.deserialize(JSON.parse(test))

...或者，与:

var test = { data: [ { type: 'ids', id: '1' }, { type: 'ids', id: '2' } ] }
UserDeserialize.deserialize(test)
