JSON.stringify 不适用于 Typescript 中对象的所有属性
JSON.stringify not working for all properties of object in Typescript
JSON.stringify 不适用于 Typescript 中最外层对象的所有属性。
请参考以下代码片段:
class Criterion {
'@CLASS' = 'xyz.abc.Criterion'
operator: string;
operand: string[];
field: string;
constructor(field:string,operator:string,operand: string[]) {
this.field = field;
this.operator = operator;
this.operand = operand;
}
}
class Filter {
'@CLASS': 'xyz.ada.Filter';
criteria: Criterion[];
constructor(criteria:Criterion[]) {
this.criteria=criteria;
}
}
var criterion = new Criterion("a","b",["c"]);
var a = new Filter([criterion]);
JSON.stringify(a);
console.log(JSON.stringify(a));
输出:
{"criteria":[{"@CLASS":"xyz.abc.Criterion","field":"a","operator":"b","operand":["c"]}]}
预计:
{"@CLASS":"xyz.ada.Filter","criteria":[{"@CLASS":"xyz.abc.Criterion","field":"a","operator":"b","operand":["c"]}]}
它没有将过滤器 class 对象的 @CLASS 属性 字符串化。
您的 class 过滤器中有错字。将两个点替换为:
'@CLASS'= 'xyz.ada.Filter';
