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的变量，并尝试像这样序列化相同的

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))

我这样得到错误： -

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

    at startup (bootstrap_node.js:146:9)

我怎么能纠正这个？

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，用：

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