后端接口设计：

**请求方式** ： PUT /password/

**请求参数**： JSON 或 表单

<table> 
 <thead> 
  <tr> 
   <th>参数</th> 
   <th>类型</th> 
   <th>是否必须</th> 
   <th>说明</th> 
  </tr> 
 </thead> 
 <tbody> 
  <tr> 
   <td>user_id</td> 
   <td>int</td> 
   <td>是</td> 
   <td>用户id</td> 
  </tr> 
  <tr> 
   <td>ipassword</td> 
   <td>str</td> 
   <td>是</td> 
   <td>原始密码</td> 
  </tr> 
  <tr> 
   <td>password</td> 
   <td>str</td> 
   <td>是</td> 
   <td>新密码1</td> 
  </tr> 
  <tr> 
   <td>password2</td> 
   <td>str</td> 
   <td>是</td> 
   <td>确认密码2</td> 
  </tr> 
 </tbody> 
</table>

**返回数据**： Response(status=status.HTTP\_202\_ACCEPTED)

### 后端实现： ###

class PassWord(APIView):
        """
        修改用户密码视图，请求接收：POST，ipassword，password，password2，
        效验原始密码ipassword正确否，
        正确的话效验新密码的正确性，返回ok，不正确返回error，
        """
    
        def put(self, request):
            # 获取参数
            ipassword = request.data["ipassword"]
            password = request.data["password"]
            password2 = request.data["password2"]
            user_id = request.data["user_id"]
            # 获得请求用户
            user = User.objects.get(id=user_id)
            # 效验新密码是否符合要求
            if password != password2:
                raise Exception("两次密码输入不一致！")
            if len(password) > 20 or len(password) < 8:
                raise Exception("密码长度需要8到20位")
            # 检查原始密码是否正确
            user.check_password(ipassword)
    
            # 修改密码为新密码
            user.set_password(password)
            user.save()
    
            # 返回数据
            return Response(status=status.HTTP_202_ACCEPTED)
