Apicloud_(项目)网上书城03_拓展模块实现　　传送门

 

ApiCloud数据云特点

　　1)无需搭建服务器、设计表结构，并且无需编写任何后端代码

　　2)默认内置user、file、role等基础数据结构，可以更具应用需求，拓展字段或自定义其它数据模型

　　3)在线可视化定义数据模型，根据数据模型自动生成RESTful API

　　4)在移动端通过云API，操作云端数据模型，业务逻辑在App端实现

 

 

实现用户注册功能

　　在login.html登陆界面中为注册按钮添加跳转事件

        <h1>用户登录</h1>
        <div class="right" tapmode onclick="fnOpenRegisterWin();">注册</div>

 

　　编写跳转页面js代码

// 打开注册Window
function fnOpenRegisterWin () {
    api.openWin({
        name: 'register',
        url: './register.html'
    });
}

 

　　在register_frame.html中为注册按钮添加点击事件

<div class="btn" tapmode="highlight" onclick="fnRegister();">注册</div>

 

　　在Script标签中添加fnRegister()注册函数

　　"X-APICloud-AppId"：填写自己项目APPID

　　"X-APICloud-AppKey"生成规则是基于SHA1()算法生成的：　　传送门

  // 注册
  function fnRegister() {
      var username = $api.byId("username");
      var password = $api.byId("password");
      var vusername = $api.val(username);
      var vpassword = $api.val(password);
      var now = Date.now();
      var appKey = SHA1("A6099005614565"+"UZ"+"5FB51794-FCDC-1FE9-19E0-A2C449C163AF"+"UZ"+now)+"."+now

      api.ajax({
          url: 'https://d.apicloud.com/mcm/api/user',
          method: 'post',
          headers: {
              "X-APICloud-AppId": "A6099005614565",
              //5FB51794-FCDC-1FE9-19E0-A2C449C163AF
              "X-APICloud-AppKey":appKey,
          },
          data: {
              values: {
                  username:vusername,
                  password:vpassword
              }
          }},
          function (ret,err){
            if(ret&&ret.id){
              alert("注册成功！");
            }else{
              alert("注册失败！");
            }
          }
      );
    }

 加载更新服务端数据，实现本地的数据存储

 　　使用doT模板引擎显示商品列表，在main_frame.html文件<head></head>标签中映入doT模板引擎

<script type="text/template" id="wareTemplate">
  {{~it:ware:index}}
  <div class="ware">

实现图片缓存

　　先在模板引擎中将图像utl放入<img>的data-url属性中，在onload函数被调用时读取data-url属性并调用api.imageCache()进行缓存，最后将缓存结果给<img>的src属性来进行图片的加载

　　修改doT模板中商品图片的代码为

<img onload="fnLoadImage(this)" data-url="{{=ware.thumbnail.url}}" class="thumbnail" src="../image/default_rect.png">

 

　　在<script>中实现商品列表的图片缓存函数

　　// 实现商品列表的图片缓存
     function fnLoadImage(ele_) {
         var dataUrl = $api.attr(ele_, 'data-url');
         // 缓存data-url所指定的图片
         if (dataUrl) {
             api.imageCache({
                 url: dataUrl
             }, function(ret, err) {
                 if (ret) {
                     ele_.src = ret.url;
                 }
             });
         }

实现下拉刷新

　　在html_frame中实现下拉刷新api.setRefreshHeaderInfo

      api.setRefreshHeaderInfo({
          loadingImg: 'widget://image/refresh.png',
          bgColor: '#fff',
          textColor: '#e1017e',
          showTime: true
      }, function(ret, err) {
          // 刷新商品列表
          fnLoadWares();
      });

 

　　将获取商品列表的代码封装为函数fnLoadWares()，并修改apiready()函数，在apiready()函数中直接调用fnLoadWares()函数

     function fnLoadWares() {
       var now = Date.now();
       var appKey = SHA1("A6099255481782"+"UZ"+"6FAE7BB1-8CFA-5087-1914-CCFB04C5EB85"+"UZ"+now)+"."+now
       var params = {
           fields: {},
           where: {
               supportAreaId: "56c80e0c789b068408ab5a6f",
               wareTypeId: api.pageParam.wareTypeId
           },
           skip: 0,
           limit: 5
       };
       api.ajax({
           url: 'http://d.apicloud.com/mcm/api/ware?filter=' + $api.jsonToStr(params),
           method: 'get',
           headers: {
               "X-APICloud-AppId": "A6099255481782",
               "X-APICloud-AppKey":appKey
           }
       }, function(ret, err) {
         api.refreshHeaderLoadDone();
           if(ret){
             var strTemplate = $api.html
             (
               $api.byId('wareTemplate')
             );
             var fnTemplate = doT.template(strTemplate);
             strTemplate = fnTemplate(ret);
             var list = $api.byId('list');
             $api.html(list, strTemplate);

           }
           else{
             alert(JSON.stringify(err));
           }
        }
      );

     }

 

 　　在apiready函数中，页面打开的时候首先会加载一次商品列表，接着会通过api.setRefreshHeaderInfo()设置下拉刷新组件，在下拉进行后(回调函数被执行)会再次加载商品列表。最后修改api.ajax()的回调函数，获取商品列表后通过 api.refreshHeaderLoadDone()关闭下拉刷新组件

实现上拉加载更多

　　在main_frame.html中的apiready函数中添加

        api.addEventListener({
              name:'scrolltobottom',
              extra:{
                threshold:300://距离底部患有多少触发scrolltobottom事件
              },function(ret,err){
                //获取更多的商品
                fnLoadWares(true);
              }
        });

 

　　修改fnLoadWares()函数

   var skip = 0;
       var limit = 5;
       function fnLoadWares(more){
         if(more){
           skip+=limit;
         }else{
           skip=0;
         }
       var now = Date.now();
       var appKey = SHA1("A6099255481782"+"UZ"+"6FAE7BB1-8CFA-5087-1914-CCFB04C5EB85"+"UZ"+now)+"."+now
       var params = {
           fields: {},
           where: {
               supportAreaId: "56c80e0c789b068408ab5a6f",
               wareTypeId: api.pageParam.wareTypeId
           },
           skip: 0,
           limit: 5
       };
       api.ajax({
           url: 'http://d.apicloud.com/mcm/api/ware?filter=' + $api.jsonToStr(params),
           method: 'get',
           headers: {
               "X-APICloud-AppId": "A6099255481782",
               "X-APICloud-AppKey":appKey
           }
       }, function(ret, err) {
           if(ret){
             var strTemplate = $api.html
             (
               $api.byId('wareTemplate')
             );
             var fnTemplate = doT.template(strTemplate);
             strTemplate = fnTemplate(ret);
             var list = $api.byId('list');
             if(more){
               $api.append(list, strTemplate);
             }else{
                $api.html(list, strTemplate);
             }
            api.refreshHeaderLoadDone();
           }
           else{
             alert(JSON.stringify(err));
           }
        }
      );
     }

 

　　首先通过api.addEventListener()监听scrolltobottom事件，然后再事件触发后调用fnLoadWares(true)来加载更多的商品。fnLoadWares()函数的唯一参数表示是否加载更多。然后将ship和limit字段提出，当加载更多时更新skip的数值即可。最后再输出内容时分别使用$api.html()和$api.append()来处理不同的情况，在“图书”列表下可以体验效果

实现保存登陆信息

　　实现保存登陆信息，这里用到本地存储。在用户未登录时如果点击右上角的个人中心按钮，会跳转到登陆页面，如果用户已登陆则会跳转到个人中心页面

　　添加personalcenter.html和personalcenter_frame.html用户中心的静态界面

　　修改login_frame.html中登陆请求的回调函数

      function (ret,err){
            if(ret&&ret.userId){
              $api.setStorage('userInfo', ret);
              api.closeToWin({
                  name: 'main'
              });
            }else{
              alert("登陆失败！");
            }
          }

 

　　这里首先将登陆成果返回的结果保存到本地userInfo字段中。接着关闭当前屏幕Window栈里的所有Window，回到名称为main的Window(首页)

  function fnOpenPersonalCenterWin() {
          // 从缓存中获取用户信息
          var userInfo = $api.getStorage('userInfo');
    
          // 判断当前用户是否登录了
          if (userInfo ) {
              // 登录成功，打开个人中心Window
              api.openWin({
                  name: 'personalcenter',
                  url: './personalcenter.html',
                  pageParam:{
                    userId:userInfo.userId
                  }
              });
          } else {
              // 没有登录，打开登录Window
              api.openWin({
                  name: 'login',
                  url: './login.html'
              });
          }
      }

 

　　这里先获得本地存储的userInfo字段，如果找到，则打开个人中心界面，并使用其中的userId作为参数，如果获取不到则打开登陆页面

　　点击个人中心左下角的设置按钮进入设置页面，完成设置页面的静态页面setting.html和setting_frame.html的编写

　　打开setting_frame.html，为退出登陆按钮添加点击事件

function fnLogout() {
    api.confirm({
        title: '提示',
        msg: '是否退出登录',
        buttons: ['确定', '取消']
    }, function(ret, err) {
        if (ret) {
            if (1 == ret.buttonIndex) {
                $api.rmStorage('userInfo');
                api.closeToWin({
                    name: 'main'
                });
            }
        }
    });
}

 

　　这里使用api.comfirm()来弹出交互对话框。在用户点击某个按钮后会调用回调函数，ret.buttonIndex是用户点击的按钮索引

实现清除缓存

　　通在setting_frame.html的apiready函数中得到缓存大小，并为“清除缓存”按钮添加点击事件

　　通过api.geyCacheSize()获取缓存大小

　　通过cnClearCache()函数清除缓存

apiready = function() {
    getCacheSize();
};

function getCacheSize() {
    api.getCacheSize(function(ret) {
        var size = ret.size;
        var cacheSize = $api.byId('cacheSize');
        size = parseInt((size / 1024 / 1024) * 100) / 100;
        cacheSize.innerHTML = size + ' M';
    });
}

function fnClearCache() {
    api.clearCache(function() {
        api.toast({
            msg: '缓存清除完毕'
        });
        setTimeout(function() {
            getCacheSize();
        }, 300);
    });
}

function fnOpenAboutWin () {
    api.openWin({
        name: 'about',
        url: './about.html'
    });
}

function fnLogout() {
    api.confirm({
        title: '提示',
        msg: '是否退出登录',
        buttons: ['确定', '取消']
    }, function(ret, err) {
        if (ret) {
            if (1 == ret.buttonIndex) {
                $api.rmStorage('userInfo');
                api.closeToWin({
                    name: 'main'
                });
            }
        }
    });
}

 

 

　　这里通过api.clearCache()清除缓存，之后弹出提示并在一定事件后重新获取缓存大小

　　可以看到，清除缓存后，缓存由原来1.75边了0.57，不过清除了缓存后首页图片出现了丢失图片现象
