Question

基本上，我的问题归结为以下事实：我无法拥有与用于getter或setter的名称相同的属性。此问题有更多详细信息：Duplicate declaration TypeScript Getter Setter。

因此，为了避免出现这种情况，我通过以下方式创建我的课程（此处仅显示其私有字段之一）：

export class RFilter
{
    private _phone_model: string;

    constructor(task: Task)
    {
        this.phone_model = task.phone_model;
    }

    set phone_model(val: string)
    {
        this._phone_model = val;
    }

    get phone_model(): string
    {
        return this._phone_model;
    }

此问题是服务器希望该字段的名称为phone_model，而不是_phone_model。我知道我可以给我的getter和setter方法命名，例如Phone_model，然后将私有字段重命名为phone_model，但是...这违反约定。

处理此问题的正确方法是什么？

So I did some checking and the following should bypass the manual JSON (I had the idea, but the nice code I have found on SO)

Add this on the top of your class (original code: Get properties of class in typescript / @nitzantomer):

public static getGetters(): string[] {
   return Reflect.ownKeys(this.prototype).filter(name => {
      return typeof Reflect.getOwnPropertyDescriptor(this.prototype, name)["get"] === "function";
 }) as string[];

after that you can use

let rFilter = new RFilter();
rFilter.phone_model = "flashy phone";

let obj = {};

for (getter of RFilter.getGetters()) {
   console.log(getter " - "+rFilter[getter]);
   obj[name] = settings[name];
}

console.log(JSON.stringify(obj));
