瀑布流

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:
