javascript - 将 ES6 类转换为 Typescript 类

Question

我有以下 ES6 类。

class Http {
    isFormData;
    url;
    token;
    data;

    constructor() {
        this.isFormData = false;
        this.url = '';
        this.token = '';
        this.data = {};
    }

    /** Set url */
    setUrl(url: string) {
        this.url = url;
        return this;
    }

    /** Set data */
      setData(data: Object) {
        this.data = data;
        return this;
    }
}

export default new Http();

我想将其设为 typescript 类。我尝试过，但某些属性未正确识别。我怎样才能使它成为 typescript 类？

Answer 1

您需要指定属性的类型。我还建议您将它们设为私有(private):

class Http {
    private isFormData: boolean;
    private url: string;
    private token: string;
    private data: Object;

    constructor() {
        this.isFormData = false;
        this.url = '';
        this.token = '';
        this.data = {};
    }

    /** Set url */
    setUrl(url: string) {
        this.url = url;
        return this;
    }

    /** Set data */
    setData(data: Object) {
        this.data = data;
        return this;
    }
}

export default new Http();
