+# TestFB
+> 使用Go语言，实现用户登录、获取用户信息、修改用户信息。
+
+## 工程要求：结构化工程，更加规范的代码编写。
+## 工程使用的模块或技术：
+1. Go语言
+2. fiber框架
+3. Gorm ORM框架
+4. fiber下的storage/redis v3模块
+5. JWT身份验证，存储在redis中
+6. mysql，使用fiber下的storage/mysql v2模块
+7. 日志，使用fiber自带的日志模块
+
+## mysql模块
+1. 数据库地址：localhost:3306
+2. 数据库名称：testfb
+3. 表名称：users
+4. 字段：id, username, password, email, phone, created_at, updated_at
+5. 密码字段需加密。
+## redis模块
+1. 存储用户的token信息
+2. redis地址：localhost:6379
+
+## 路由信息
+1. 登录：POST /login
+2. 获取当前用户信息: GET /user
+3. 修改当前用户信息: PUT /user
+4. 获取某个用户信息: GET /users/:id
+
+## 其他
+1. 日志保存在当前main.go目录下
