数据库说明\n\n\n![database.png](https://p6-juejin.byteimg.com/tos-cn-i-k3u1fbpfcp/892fbbe46695467ebe4fb4a12ebd412e~tplv-k3u1fbpfcp-watermark.image?)\n\n> 单纯看上面的图会感觉很混乱，现在我们来将关系拆解。\n\n### 数据库关系说明\n\n**关系图如下：**\n\n\n![database_relation.png](https://p6-juejin.byteimg.com/tos-cn-i-k3u1fbpfcp/f08918db1ea84126bc21d23fe9401a75~tplv-k3u1fbpfcp-watermark.image?)\n\n> 所有的表都有自己的id主键为唯一的标识。\n\nuser_logins：存下用户的用户名和密码\n\nuser_infos：存下用户的基本信息\n\nvideos：存下视频的基本信息\n\ncomment：存下每个评论的基本信息\n\n**具体的关系索引：**\n\n所有的一对一和一对多关系，只需要在一个表中加入对方的id索引。\n\n* 比如user_infos和user_logins的一对一关系，在user_logins中加入user_id字段设为外键存储user_infos中对应的行的id信息。\n* 比如user_infos和和videos的一对多关系，在videos中加入user_id字段设为外键存储user_infos中对应的行的id信息。\n\n所有的多对多关系，需要多建立一张表，用该表作为媒介存储两个对象的id作为关系的产生，而它们各自表中不需要再存下额外的字段。\n\n* 比如user_infos和videos的多对多关系，创建一张user_favor_videos中间表，然后将该表的字段均设为外键，分别存下user_infos和videos对应行的id。如id为1的用户对id为2的视频点了个赞，那么就把这个1和2存入中间表user_favor_videos即可。\n\n### 数据库建立说明\n\n数据库各表的建立无需自己实现额外的建表操作，一切都由gorm框架自动建表，具体逻辑在models层的代码中。\n\n> gorm官方文档链接：[链接](https://gorm.io/zh_CN/docs/index.html)\n\n建表和初始化操作由init_db.go来执行：\n\n```go\nfunc InitDB() {\n\tvar err error\n\tDB, err = gorm.Open(mysql.Open(config.DBConnectString()), &gorm.Config{\n\t\tPrepareStmt: true, //缓存预编译命令\n\t\tSkipDefaultTransaction: true, //禁用默认事务操作\n\t\t//Logger: logger.Default.LogMode(logger.Info), //打印sql语句\n\t})\n\tif err != nil {\n\t\tpanic(err)\n\t}\n\terr = DB.AutoMigrate(&UserInfo{}, &Video{}, &Comment{}, &UserLogin{})\n\tif err != nil {\n\t\tpanic(err)\n\t}\n}\n```\n\n## 架构说明\n\n\n![architecture.png](https://p3-juejin.byteimg.com/tos-cn-i-k3u1fbpfcp/ae11d82b8de74787a258ef36f4cf2557~tplv-k3u1fbpfcp-watermark.image?)\n\n> 以用户登录为例共需要经过以下过程：\n\n1. 进入中间件SHAMiddleWare内的函数逻辑，得到password明文加密后再设置password。具体需要调用gin.Context的Set方法设置password。随后调用next()方法继续下层路由。\n2. 进入UserLoginHandler函数逻辑，获取username，并调用gin.Context的Get方法得到中间件设置的password。再调用service层的QueryUserLogin函数。\n3. 进入QueryUserLogin函数逻辑，执行三个过程：checkNum，prepareData，packData。也就是检查参数、准备数据、打包数据，准备数据的过程中会调用models层的UserLoginDAO。\n4. 进入UserLoginDAO的逻辑，执行最终的数据库请求过程，返回给上层。\n\n### 各模块代码详细说明\n\n我开发的过程中是以单个函数为单个文件进行开发，所以代码会比较长，故我根据数据库内的模型对函数文件进行了如下分包：\n\n\n![handlers.png](https://p1-juejin.byteimg.com/tos-cn-i-k3u1fbpfcp/6dc222793d6f4038b1bf2435053bfee4~tplv-k3u1fbpfcp-watermark.image?)\n\nservice层的分包也是一样的。\n\n#### Handlers\n\n对于handlers层级的所有函数实现有如下规范：\n\n所有的逻辑由代理对象进行，完成以下两个逻辑\n\n1. 解析得到参数。\n2. 开始调用下层逻辑。\n\n例如一个关注动作触发的逻辑：\n\n```go\nNewProxyPostFollowAction().Do()\n//其中Do主要包含以下两个逻辑，对应两个方法\np.parseNum() //解析参数\np.startAction() //开始调用下层逻辑\n```\n\n#### Service\n\n对于service层级的函数实现由如下规范：\n\n同样由一个代理对象进行，完成以下三个或两个逻辑\n\n当上层需要返回数据信息，则进行三个逻辑：\n\n1. 检查参数。\n2. 准备数据。\n3. 打包数据。\n\n当上层不需要返回数据信息，则进行两个逻辑：\n\n1. 检查参数。\n2. 执行上层指定的动作。\n\n例如关注动作在service层的逻辑属于第二类：\n\n```go\nNewPostFollowActionFlow(...).Do()\n//Do中包含以下两个逻辑\np.checkNum() //检查参数\np.publish() //执行动作\n```\n\n#### Models\n\n对于models层的各个操作，没有像service和handler层针对前端发来的请求就行对应的处理，models层是面向于数据库的增删改查，不需要考虑和上层的交互。\n\n而service层根据上层的需要来调用models层的不同代码请求数据库内的内容。\n\n## 遇到的问题及对应解决方案\n\n### 返回json数据的完整性和前端要求的一致性\n\n由于数据库内的一对一、一对多、多对多关系是根据id进行映射，所以models层请求得到的字段并不包含前端所需要的直接数据，比如前端要求Comment结构中需要包含UserInfo，而我的Comment结构如下：\n\n```go\ntype Comment struct {\n\tId int64 `json:\"id\"`\n\tUserInfoId int64 `json:\"-\"` //用于一对多关系的id\n\tVideoId int64 `json:\"-\"` //一对多，视频对评论\n\tUser UserInfo `json:\"user\" gorm:\"-\"`\n\tContent string `json:\"content\"`\n\tCreatedAt time.Time `json:\"-\"`\n\tCreateDate string `json:\"create_date\" gorm:\"-\"`\n}\n```\n\n很明显，为了与数据库中设计的表一一对应，在原数据的基础上加了几个字段，且在gorm屏蔽了User字段，所以service调用models层得到是Comment数据中User字段还未被填充，还需再填充这部分内容，好在由对应的UserId，故可以正确填充该字段。\n\n为了重用以及不破坏代码的一致性，将填充逻辑写入util包内，比如以上的字段填充函数，同时前端要求的日期格式也能够按要求设置：\n\n```go\nfunc FillCommentListFields(comments *[]*models.Comment) error {\n\tsize := len(*comments)\n\tif comments == nil || size == 0 {\n\t\treturn errors.New(\"util.FillCommentListFields comments为空\")\n\t}\n\tdao := models.NewUserInfoDAO()\n\tfor _, v := range *comments {\n\t\t_ = dao.QueryUserInfoById(v.UserInfoId, &v.User) //填充这条评论的作者信息\n\t\tv.CreateDate = v.CreatedAt.Format(\"1-2\") //转为前端要求的日期格式\n\t}\n\treturn nil\n}\n```\n\n这里举了Comment这一个例子，其他的Video也是同理。\n\n### is_favorite和is_follow字段的更新\n\n每次为视频点赞都会在数据库的user_favor_videos表中加入用户的id和视频的id，很明显is_favorite字段是针对每个用户来判断的，而我所设计的数据库中的videos表也是包含这个字段的，但这个字段很明显不能直接进行复用，而是需要每次判断用户和此视频的关系来重新更新。\n\n这个更新过程放入util包的填充函数中即可，为了点赞过程的迅速响应，我采取了nosql的方式存储了这个点赞的映射，也就是userId和videoId的映射，也就是用nosql代替了这个中间表的功效。\n\n具体代码逻辑在cache包内。\n\n### 视频的保存和封面的切片\n\n#### 视频的保存\n\n在本地建立static文件夹存储视频和封面图片。\n\n具体逻辑如下：\n\n1. 检查视频格式\n2. 根据userId和该作者发布的视频数量产生唯一的名称，如id为1的用户发布了0个视频，那么本次上传的名称为1-0.mp4\n3. 截取第一帧画面作为封面\n4. 保存视频基本信息到数据库（包括视频链接和封面链接\n\n#### 封面的截取\n\n使用ffmpeg调用命令行对视频进行截取。\n\n设计ffmpeg请求类Video2Image，通过对它内部的参数设置来构造对应的命令行字符串。具体请看util包内的ffmpeg.go的实现。\n\n由于我设计的命令请求字符串是直接的一行字符串，而go语言exec包里面的Command函数执行所需的仅仅是一个个参数。\n\n所以此处我想到用cgo直接调用 system(args)来解决。\n\n代码如下：\n\n```go\n//#include \n//int startCmd(const char* cmd){\n//\t return system(cmd);\n//}\nimport \"C\"\n\nfunc (v *Video2Image) ExecCommand(cmd string) error {\n\tif v.debug {\n\t\tlog.Println(cmd)\n\t}\n\tcCmd := C.CString(cmd)\n\tdefer C.free(unsafe.Pointer(cCmd))\n\tstatus := C.startCmd(cCmd)\n\tif status != 0 {\n\t\treturn errors.New(\"视频切截图失败\")\n\t}\n\treturn nil\n}\n```\n\n## 可改进的地方\n\n1. 写到后面发现很多mysql的数据可以用redis优化。\n2. 很多执行逻辑可以通过并行优化。\n3. 路由分组可以更为详实。\n4. ...\n\n## 项目运行\n\n> 本项目运行不需要手动建表，项目启动后会自动建表。\n\n**运行所需环境**：\n\n* mysql 5.7及以上\n* redis 5.0.14及以上\n* ffmepg（已放入lib自带，用于对视频切片得到封面\n* 需要gcc环境（主要用于cgo，windows请将mingw-w64设置到环境变量\n\n**运行需要更改配置**：\n\n> 进入config目录更改对应的mysql、redis、server、path信息。\n\n* mysql：mysql相关的配置信息\n* redis：redis相关配置信息\n* server：当前服务器（当前启动的机器）的配置信息，用于生成对应的视频和图片链接\n* path：其中ffmpeg_path为lib里的文件路径，static_source_path为本项目的static目录，这里请根据本地的绝对路径进行更改\n\n> 完成config配置文件的更改后，需要再更改conf.go里的解析文件路径为config.toml文件的绝对路径，内容如下：\n>\n> ```go\n> if _, err := toml.DecodeFile(\"你的绝对路径\\\\config.toml\", &Info); err != nil {\n> \t\tpanic(err)\n> \t}\n> ```\n>\n>\n\n**运行所需命令**：\n\n```shell\ncd .\\byte_douyin_project\\\ngo run
