go开发视频后台服务

GO+GORM+GIN+REDIS+UUID+DOCKER

编译和运行(可以使用docker了)

go build
启动 redis
启动 govideo_server
浏览器访问 http://localhost/web

docker编译运行

#下载更新镜像
docker pull gongluck/govideo_server

#手动运行
docker run -d --name redis redis
docker run -i -t --name govideo -p 80:80 -v /e/code/govideo_server/videos:/govideo_server/videos -v /e/code/govideo_server/conf:/govideo_server/conf -v /e/code/govideo_server/database:/govideo_server/database --link redis:redis gongluck/govideo_server

#脚本运行
wget https://raw.githubusercontent.com/gongluck/govideo_server/master/docker-compose.yml
mkdir conf
cd conf
wget https://raw.githubusercontent.com/gongluck/govideo_server/master/conf/config.yml
cd ..
docker-compose up -d
docker-compose down

数据库设计

users表

字段	描述	类型
id	用户唯一标识(主键,自动增长)	INTEGER
name	用户名(非空,唯一)	text
password	密码(密文)	text
level	用户等级(非空)	INTEGER

videos表

字段	描述	类型
id	视频唯一标识(主键,自动增长)	INTEGER
title	视频标题(非空)	text
description	视频描述	text
filepath	视频文件路径(非空)	text
userid	所属用户id	INTEGER

表结构定义

数据库模块使用GORM

type User struct {
	//gorm.Model
	ID       int64   `gorm:"column:id;type:integer;primary_key;auto_increment"`
	Name     string `gorm:"column:name;type:text;not null;unique"`
	Password string `gorm:"column:password;type:text;not null"`
	Level    int64   `gorm:"column:level;type:integer"`
}
type Video struct {
	//gorm.Model
	ID          int64  `json:"id"gorm:"column:id;primary_key;auto_increment"`
	Title       string `json:"title"gorm:"column:title;type:text;not null"`
	Description string `json:"description"gorm:"column:description;type:text"`
	Filepath    string `json:"filepath"gorm:"column:filepath;not null"`
	Userid      int64  `json:"userid"gorm:"column:userid;type:integer;not null"`
}

会话管理

使用Gin的session和其封装的Redis。

windows版本的redis使用这个版本redis

package util

import (
	"github.com/gin-contrib/sessions"
	"github.com/gin-gonic/gin"
	uuid "github.com/satori/go.uuid"
)

func NewUUID() string {
	sessionid := uuid.NewV4()
	return sessionid.String()
}

func SetSession(c *gin.Context, userid int64) error {
	uuidstr := NewUUID()
	session := sessions.Default(c)
	session.Set("session", uuidstr)
	session.Set(uuidstr, userid)
	return session.Save()
}

func GetSessionAndUser(c *gin.Context) (interface{}, interface{}) {
	session := sessions.Default(c)
	vsession := session.Get("session")
	if vsession == nil {
		return nil, nil
	}

	user := session.Get(vsession)
	return vsession, user
}

func DelSession(c *gin.Context) error {
	session := sessions.Default(c)
	vsession, user := GetSessionAndUser(c)

	if vsession != nil {
		session.Delete(vsession)
	}
	if user != nil {
		session.Delete(user)
	}
	return session.Save()
}

func GetUserID(c *gin.Context) int64 {
	session := sessions.Default(c)
	vsession := session.Get("session")
	user := session.Get(vsession)
	if user == nil {
		return 0
	} else {
		return user.(int64)
	}
}
