Apicloud_(项目)网上书城02_后端数据获取 传送门
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({

"X-APICloud-AppKey":appKey,
},
data: {
values: {

password:vpassword
}
}},
function (ret,err){
if(ret&&ret.id){
alert("注册成功！");
}else{
alert("注册失败！");
}
}
);
}

main_frame.html
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

api.addEventListener({

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

},
skip: 0,
limit: 5
};
api.ajax({

}, 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

personalcenter_frame.html
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

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
