聚合数据API申请链接:https://www.juhe.cn/docs/api/id/235

架在服务器上。 地址可访问:http://106.13.193.149:8081/
后端使用的是nodejs(express+superagent)
直接上代码:
文件目录:

app.js


//superagent是一个HTTP库
这里之所以用superagent,也是因为前端页面如果直接掉聚合数据api 会出现跨域。
const superagent= require('superagent');
var express = require('express');
var app = express();
//解决跨域
app.all('*', function (req, res, next) {
    res.header('Access-Control-Allow-Origin', '*');
    //Access-Control-Allow-Headers ,可根据浏览器的F12查看,把对应的粘贴在这里就行
    res.header('Access-Control-Allow-Headers', 'Content-Type');
    res.header('Access-Control-Allow-Methods', '*');
    res.header('Content-Type', 'application/json;charset=utf-8');
    next();
  });
//静态资源路径
app.use('/public', express.static('public'));
//首页
app.get('/', function (req, res) {
    res.sendFile( __dirname + "/" + "toutiao.html" );
})
//首页会调用此接口,携带参数type 可返回不同的新闻类型
 app.get('/get_toutiao',(req,res)=>{
  console.log(req.query.type)
  superagent.get(`http://v.juhe.cn/toutiao/index?key=58ff2000704bbf8e31ce031c1b555a33&type=${req.query.type}`).end((err, reso) => {
    // console.log(reso);
    //返回的是字符,需要前端页面转换为对象
     res.jsonp({
       data:reso
     })
  });
})
var server = app.listen(8081, function () {
 
  var host = server.address().address
  var port = server.address().port
 
  console.log("应用实例,访问地址为 http://%s:%s", host, port)
 
})
