装饰器编写get请求

说明

本文演示使用装饰器编写get请求的方法

准备工作

mkdir demo
touch index.ts
npm i axios -S

编写代码

import axios from "axios";


const Get = (url: string) => {
    return (target: any, key: any, descriptor: PropertyDescriptor) => {
        const fnc = descriptor.value
        axios.get(url).then(res => {
            fnc(res, {
                status: 200,
                success: true
            })
        }).catch(e => {
            fnc(e, { status: 500, success: false })
        })
    }
}

class Controller {
    constructor() {
    }
    @Get('https://api.apiopen.top/api/getHaoKanVideo?page=0&size=10')
    getList(res: any, status: any) {
        console.log(res.data.result.list,status)
    }

}

测试执行ts-node .\index.ts,返回数据如下
