README
极简版抖音服务端
一、介绍
- 1.基于RPC框架Kitex、HTTP框架Gin、ORM框架GORM的极简版抖音服务端项目
- 2.代码采用api层、service层、dal层三层结构
- 3.使用Kitex构建RPC微服务，Gin构建HTTP服务
- 4.GORM操作MySQL数据库，防止SQL注入，使用事务保证数据一致性，完整性
- 5.使用ETCD进行服务注册、服务发现，Jarger进行链路追踪
- 6.使用MySQL数据库进行数据存储，并建立索引
- 7.使用OSS进行视频对象存储，分片上传视频
- 8.使用JWT鉴权，MD5密码加密，ffmpeg获取视频第一帧当作视频封面
- 9.进行了单元测试，api自动化测试，Apifox接口文档
- 10.演示视频及客户端apk

四、文件目录结构
| 目录 | 说明 |
|---|---|
| cmd/api | api层代码，处理外部http请求，通过rpc客户端发起rpc请求 |
| cmd/feed | 视频流微服务，包含获取视频流功能，处理api层rpc请求，调用dal层处理数据 |
| cmd/publish | publish微服务，包含视频上传、视频列表等功能，处理api层rpc请求，调用dal层处理数据 |
| cmd/user | user微服务，包含用户注册、用户登录、用户信息等功能，处理api层rpc请求，调用dal层处理数据 |
| cmd/favorite | favorite微服务，包含点赞、取消点赞、点赞列表等功能，处理api层rpc请求，调用dal层处理数据 |
| cmd/comment | comment微服务，包含增加评论，删除评论，评论列表等功能，处理api层rpc请求，调用dal层处理数据 |
| cmd/relation | relation微服务，包含关注、取消关注、关注列表等功能，处理api层rpc请求，调用dal层处理数据 |
| dal/db | 使用gorm进行底层数据库操作 |
| dal/pack | 封装gorm结构数据为protobuf结构数据 |
| idl | proto IDL文件 |
| kitex_gen | kitex框架生成的IDL内容相关代码 |
| pkg/bound | 限制CPU的相关代码 |
| pkg/constants | 项目中的配置及常量代码 |
| pkg/errno | 错误码的代码封装 |
| pkg/jwt | jwt鉴权的代码封装 |
| pkg/middleware | rpc的中间件 |
| pkg/oss | oss操作的相关代码 |
| pkg/tracer | 初始化jaeger |
| public | 存放本地视频 |
五、代码运行
1.更改配置
更改 constants/constant.go 中的地址配置
2.建立基础依赖
docker-compose up
3.运行feed微服务
cd cmd/feed
sh build.sh
sh output/bootstrap.sh
4.运行publish微服务
cd cmd/publish
sh build.sh
sh output/bootstrap.sh
5.运行user微服务
cd cmd/user
sh build.sh
sh output/bootstrap.sh
6.运行favorite微服务
cd cmd/favorite
sh build.sh
sh output/bootstrap.sh
7.运行comment微服务
cd cmd/comment
sh build.sh
sh output/bootstrap.sh
8.运行relation微服务
cd cmd/relation
sh build.sh
sh output/bootstrap.sh
9.运行api微服务
cd cmd/api
chmod +x run.sh
./run.sh
10.Jaeger链路追踪
