来由：由于微信小程序的路由跳转，传参写法不太友好，如果想直接传个对象过去还要转成字符串的形式，而且大小也有限制

功能：

• 支持原生小程序方式跳转
• 支持对象形式传参

路由跳转传参：

Route.navigateTo('../page/page',{name:'jslin',sex:'man',age:'18'})

获取参数：（阅后即焚，使用完将清空 params）

const params =  Route.params

相关代码：

/**
 * 路由工具,解决传参过多，支持对象形式传参
 * 用法：
 * 路由跳转
 * import Route from '../../utils/route'
 * Route.navigateTo('../page/page',{name:'jslin',sex:'man',age:'18'})
 * 
 * 路由参数获取
 * 阅后即焚 使用完，将清空 Route.params
 *  const params =  Route.params
