（14）go-micro微服务服务层Handle开发

一 Handle层开发功能说明

需要完成的服务开发功能

1. 登录
2. 注册
3. 查询用户信息
4. 修改信息
5. 发送注册邮件
6. 发送重置密码邮件
7. 重置密码
8. 获取权限
9. 修改权限
10. 退出账号
11. 删除账号
12. 禁用账号
13. 启用账号

从哪找需要开发的功能

• 找到proto/account/account.pb.micro.go文件点击结构点击AccountService
• 此部分显示的服务功能需要我们重写完成

二 代码编写

• 在handle/account.go文件中先把原来的内容删掉删掉函数即可

• 编写服务功能

package handler

import (
   "account/common/mail"
   "account/common/snow_flake"
   "account/common/token"
   "account/common/utils"
   "account/domain/model"
   "account/domain/service"
   . "account/proto/account"
   "context"
   "errors"
   "fmt"
   "time"
)

type Account struct {
   AccountService service.IUserService
}

// Login 登录
func (a *Account) Login(ctx context.Context, req *LoginRequest, rsp *LoginResponse) error {
   userInfo, err := a.AccountService.FindUserByName(req.Username)

   if err != nil {
      return err
   }
   token2, err := token.GenToken(req.Username)
   if err != nil {
      return err
   }
