微信小程序，实现一个简易的新闻网

废话不多说，先上效果图，功能实现了广播、轮播图、登入微信用户、获取收藏列表、获取新闻详情页面、页面跳转…

项目结构图：

模拟数据库页面data

data.js

/**存放公共js文件 */
//临时新闻数据
const news = [{
    
    
  id: '1',
  title: '标题一',
  
  poster: '在线图片链接地址',
  add_date: '2022-05-07',
  detail: '详细内容'
},
{
    
    
  id: '2',
  title: '标题2',
  poster: '在线图片链接地址',
  add_date: '2022-05-08',
  detail:'详细内容'
},
{
    
    
  id: '3',
  title: '标题三',
  poster: '在线图片链接地址',
  add_date: '2022-05-09',
  detail:'详细内容'
}
]

//获取新闻列表
function getNewList() {
    
    
let list = [];
for(var i = 0; i < news.length; i++) {
    
    
  let obj = {
    
    };
  obj.id = news[i].id;
  obj.poster = news[i].poster;
  obj.content = news[i].detail;
  obj.add_date = news[i].add_date;
  obj.title = news[i].title;
  // console.log('obj',obj);
  list.push(obj);
}
return list;
}

//获取新闻内容
function getNewsDetail(newsID) {
    
    
let message = {
    
    
  code: '404',
  news: {
    
    }
};
for (var i = 0; i < news.length; i++) {

    message.code = '200',
      message.news = news[i];
    break;
  }
}
return message;
}

module.exports = {
