API 利用之一，前后端完全分离和无刷新瀑布流

wellcms 前台的所有页面，均内置了 API，支持异步 GET 和 POST，可以做到完全的前后端分离。通过 API 可制作小程序和APP，现在的APP、小程序多是无刷新瀑布流，那么 wellcms 也是可以做到。

根据个人习惯，自行挑选前端框架制作小程序和APP。

1.开启 API，conf/conf.php

'api_on' => 1,

2.内置 js 获取数据

<script>    /*
    * 通过 API 获取数据，格式为 Object 无需再JSON转换，直接使用
    * 获取路径http://www.x.com/list-1.html
    * 格式化链接 xn.url('list-1')
    * 列表翻页加载 xn.url('list-1-2') 最后一个 2 为翻页码，1为第1页，2为第2页，3为第3页
    * Object 返回数据中
    * "page": 1, 为当前页码
    * "num": "2", 为当前版块主题数量，根据此数量计算分页数量
    * list 为列表页
    * 1为fid
    * 其他页面同样如此，再浏览器看到的链接都可以直接使用
    *
    * 链接有携带其他参数
    * 如http://www.x.com/list-1.html?default=1&orderby=lastpid
    * 格式化链接
    * xn.url('list-1', {'default':'1', 'orderby':'lastpid'})
    * code = 0 返回正常数据， message 为返回的数据
    * code > 0 数据错误，message 为错误提示
    * code < 0 数据不存在，message 为错误提示
    * code 返回非数字错误，表单提交的错误参数，message 为错误提示
    * 不需要显示错误，可删除
    * 学会使用 console.log(message); 打印查看数据
    * JS 代码请勿使用双斜杠 // 注释
    *  */
    $.xget(xn.url('list-1'), function (code, message) {        /*console.log(code);*/        if (0 == code) {            /*
            返回的数据，直接JS for遍历 或 JQ 渲染页面 $.each 遍历，复制列表最后一个元素，进行替换即可，wellcms 非前端渲染可达到 0.00x秒打开页面，前端渲染只会更出色。
            console.log(message);
            */        } else if (1 == code) {        } else {            /* 弹窗提示错误，根据需要可删除此处或修改message.htm */
            $.alert(message);        }    });</script>

API GET 返回 Object 格式数据：
