微信小程序云开发后端开发框架没有自带的验证性能，因而开发校友录小程序的表单验证时候个别有两种办法，一是本人裸写验证规定，然而须要比拟扎实的正则表达式根底，一种是本人封装 Validate 插件进行表单验证，基于以上起因，小女子本人封装了云开发后端数据校验规定一套，并且与前端数据校验的写法和规定统一（前端数据校验体系下一篇笔记介绍：））
对立校验路由入口
function check(data, rules, that) {let returnData = {};
for (let k in rules) {let arr = rules[k].split('|');

// 校友录小程序数据项阐明
for (let i = 0; i < arr.length; i++) {if (arr[i].indexOf('name=') > -1) {desc = arr[i].replace('name=', '');
break;
}
}
// 校友录小程序校验
let formName = arr[0];
let val = data[formName];
if (val === undefined) val = '';
if (!Array.isArray(val))
val = String(val).trim(); // 前后去空格
returnData[k] = val;
for (let i = 1; i < arr.length; i++) {
let result = '';
let rules = arr[i].split(':');
// 校友录小程序空不校验
