就是報createTime這個字段不匹配，這個字段的類型是Date。最上面一段是提示信息，下面是關(guān)于Date的定義。 與字段無關(guān)的都省略了，用...代替了

Date 類型，定義總是報錯：

... is not assignable to type 'EvaluationDTO.
Types of property 'createTime' are incompatible.
Type 'string' is not assignable to type 'Date'

private evaluationDTO: EvaluationDTO;

this.evaluationDTO = {
...
createTime: '2018-03-20',
}


export interface EvaluationDTO{
...
createTime: Date;


interface Date{
...
[Symbol.toPrimitive](hint: "default"): string;
}
}
