> 注册时候验证手机验证码  
> 验证码通过后讲用户信息存入数据库

#### 实际案例图片 ####

![注册通过后,登录成功后的页面][401c68b2fc95499684ae8dd86da52229.png]

#### 后端接口文件 index.js ####

#### 后端接口文件 UserSql.js ####

#### 用户信息保存接口文档 ####

七 增加用户接口文档  
1.1 接口功能

> 增加用户

1.2 URL

> 地址 /api/addUser

1.3 支持格式

> JSON

1.4 HTTP请求方式

> POST

1.5 请求参数

<table> 
 <thead> 
  <tr> 
   <th>参数</th> 
   <th>必选</th> 
   <th>类型</th> 
   <th>说明</th> 
  </tr> 
 </thead> 
 <tbody> 
  <tr> 
   <td>userName</td> 
   <td>是</td> 
   <td>string</td> 
   <td>手机号</td> 
  </tr> 
  <tr> 
   <td>code</td> 
   <td>是</td> 
   <td>string</td> 
   <td>验证码</td> 
  </tr> 
 </tbody> 
</table>

1.6 返回字段

<table> 
 <thead> 
  <tr> 
   <th>返回字段</th> 
   <th>字段类型</th> 
   <th>说明</th> 
  </tr> 
 </thead> 
 <tbody> 
  <tr> 
   <td>code</td> 
   <td>string</td> 
   <td>返回结果状态 0:正常 1:错误</td> 
  </tr> 
  <tr> 
   <td>data</td> 
   <td>object</td> 
   <td>商品分类数据</td> 
  </tr> 
 </tbody> 
</table>

1.7 接口示例

{
        
    	"code":'0',
    	"data":[
    		{
        
        	success:true,
        	code:6585
      	}
    }
