Nodejs如何使用http标准库异步加载https请求json数据_node.js_

//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)); } })
