概要

实现用户注册功能

新建error.go文件

$  touch ~/book/user/api/internal/logic/error.go

填充如下代码

package logic

import (
  "book/shared"
)

var (
  errorDuplicateUsername = shared.NewDefaultError("用户名已经注册")
  errorDuplicateMobile   = shared.NewDefaultError("手机号已经被占用")
)

填充注册逻辑代码

$ vi ~/book/user/api/internal/logic/registerlogic.go

增加注册逻辑

向Register方法中填充注册逻辑

// 为了简单，这里只做一下简单的逻辑校验
  _, err := l.svcCtx.UserModel.FindOneByName(req.Username)
  if err == nil {
    return errorDuplicateUsername
  }

  _, err = l.svcCtx.UserModel.FindOneByMobile(req.Mobile)
  if err == nil {
    return errorDuplicateMobile
  }

  _, err = l.svcCtx.UserModel.Insert(model.User{
    Name:     req.Username,
    Password: req.Password,
    Mobile:   req.Mobile,
    Gender:   "男",
    Nickname: "admin",
  })
  return err

访问注册协议

$ curl -i -X POST \
  http://127.0.0.1:8888/user/register \
  -H 'cache-control: no-cache' \
  -H 'content-type: application/json' \
  -d '{
        "username":"admin",
        "password":"666666",
        "mobile":"19988888888"
}'

得到响应码为200则代表注册成功

shared中文件代码 

新建baseerror.go

$ touch ~/book/shared/baseerror.go

填充如下代码

package shared

const (
  defaultCode = 1001
)

type (
  CodeError struct {
    Code int    `json:"code"`
    Msg  string `json:"msg"`
  }
)

func NewCodeError(code int, msg string) error {
  return &CodeError{Code: code, Msg: msg}
}

func NewDefaultError(msg string) error {
  return NewCodeError(defaultCode, msg)
}

func (e *CodeError) Error() string {
  return e.Msg
}
