使用http标准库异步加载https请求json数据

//通过https加载json数据
let url = 'https://img-home.csdnimg.cn/data_json/toolbar/toolbar1105.json';
let GetJsonData=function (url){
    const https = require('https');
    https.get(url, (response) => {
        let data = '';
        //数据正在接收中...
        response.on('data', (chunk) => {
            data += chunk;
        });
        //数据接收完成
        response.on('end', () => {
            console.log('同步请求数据完成:',JSON.parse(data));
        });
 
    }).on("error", (error) => {
        console.log("Error: " + error.message);
    });
}

GetJsonData(url);

//异步请求JSON数据实现
let GetJsonDataAsync=(url)=>{
    const https = require('https');
    return new Promise((resolve, reject) => {
        https.get(url, (response) => {
            let data = '';
            //数据正在接收中...
            response.on('data', (chunk) => {
                data += chunk;
            });
            //数据接收完成
            response.on('end', () => {
                //console.log(JSON.parse(data));
                resolve(data);//数据接收完成
            });
 
        }).on("error", (error) => {
            console.log("Error: " + error.message);
            reject(new Error(error.message));
        });
    });
};

//异步调用
GetJsonDataAsync(url).then(value => {
    console.log("======================下面为异步加载数据=================================");
    if (typeof value === "string") {
        console.log('异步加载请求数据完成:', JSON.parse(value));
    }
})
