微信小程序云数据库实现注册

微信小程序自带的云数据库的优势在于，不用搭建服务器和后端就可以直接调用数据库

我们接下来使用云数据库实现注册功能，效果图如下

云数据库结构如下：

这是用云数据库实现注册功能，实现代码如下，：

   register.wxml

    

 
  注册
  
        
               
          
  
  
        
               
         
  
   
        
               
         
  
   
        
               
         
  
  提交
