 	- Go 的指针**不支持算术运算**，避免了内存越界和非法访问的风险，同时通过垃圾回收机制自动管理内存，**减少了内存泄漏的可能性**。
-	- Go 的指针类型严格区分，空指针用 `nil` 表示，解引用空指针会触发 panic，不支持**指针算术运算和强制类型转换**。

+### CRUD操作
+#### 创建数据

+```
+- save方式
+```go
+db.First(&user,1)
+db.Save(&user) //更新所有字段
+db.Save(&user).Omit("Name") //更新除Name字段外的所有字段
+```
+#### 删除记录
+```go
+db.Delete(&user) //软删除
+db.Unscoped().Delete(&user) //直接强制删除

+### TOML 简介
+
+TOML（Tom's Obvious, Minimal Language）是一种配置文件格式，旨在易于阅读和编写。它的语法类似于INI文件，但更强大和灵活。
+
+#### 基本语法
+
+1. **键值对**：
+   ```toml
+   key = "value"
+   ```
+
+2. **字符串**：
+   ```toml
+   string = "Hello, World!"
+   multi_line_string = """
+   This is a
+   multi-line string.
+	nihao
+   """
+   ```
+
+3. **数字**：
+   ```toml
+   integer = 42
+   float = 3.14
+   ```
+
+4. **布尔值**：
+   ```toml
+   boolean = true
+   ```
+
+5. **数组**：
+   ```toml
+   array = [1, 2, 3]
+   ```
+
+6. **表（嵌套结构）**：
+   ```toml
+   [table]
+   key = "value"
+   ```
+
+7. **数组表**：
+   ```toml
+   [[array_table]]
+   name = "Alice"
+   [[array_table]]
+   name = "Bob"
+   ```
+
+### 使用 Go 的 Viper 解析 TOML
+
+在go中，有很多的库可以解析Toml,在这里我推荐使用Viper来进行处理。Viper 是一个强大的 Go 库，用于处理配置文件，支持多种格式，不仅仅是TOML。
+#### 示例代码
+
+1. **创建 TOML 文件**（`config.toml`）：
+   ```toml
+   app_name = "Class"
+   port = 8080
+
+   [database]
+   host = "localhost"
+   port = 3306
+   user = "yzk_study"
+   password = "yzk722923"
+   ```
+
+2. **使用 Viper 解析 TOML**：
+   ```go
+   package main
+
+   import (
+       "fmt"
+       "github.com/spf13/viper"
+   )
+
+   func main() {
+       // 设置配置文件名和路径
+       viper.SetConfigName("config") // 文件名（不带扩展名）
+       viper.SetConfigType("toml")   // 文件类型
+       viper.AddConfigPath(".")      // 查找路径
+
+       // 读取配置文件
+       if err := viper.ReadInConfig(); err != nil {
+           panic(fmt.Errorf("Fatal error config file: %s \n", err))
+       }
+
+       // 获取配置值
+       appName := viper.GetString("app_name")
+       port := viper.GetInt("port")
+       dbHost := viper.GetString("database.host")
+       dbPort := viper.GetInt("database.port")
+
+       fmt.Printf("App Name: %s\n", appName)
+       fmt.Printf("Port: %d\n", port)
+       fmt.Printf("Database Host: %s\n", dbHost)
+       fmt.Printf("Database Port: %d\n", dbPort)
+   }
+   ```
+
+#### 运行结果
+
+```bash
+App Name: MyApp
+Port: 8080
+Database Host: localhost
+Database Port: 5432
+```
+
+### 总结
+
+- **TOML** 是一种易于阅读和编写的配置文件格式。
+- **Viper** 是一个强大的 Go 库，支持多种配置文件格式，包括 TOML。
+- 通过 Viper，可以轻松读取和解析 TOML 文件中的配置项。

+# Gin的使用
+## Gin是什么
+- Gin 是一个用 Go 语言编写的高性能 Web 框架，以其快速的路由和中间件支持著称。它基于 `httprouter`，提供了简洁的 API 和强大的功能，适合构建高效的 Web 应用和 API。
+
+## 如何使用Gin
+### 创建一个最基本的Gin程序
+ ```go
+package main
+
+import (
+    "github.com/gin-gonic/gin"
+)
+
+func main() {
+    // 创建默认 Gin 实例
+    r := gin.Default()
+
+    // 定义路由和处理函数
+    r.GET("/", func(c *gin.Context) {
+        c.JSON(200, gin.H{
+            "message": "Hello, Gin!",
+        })
+    })
+    // 启动服务器，默认监听 8080 端口
+    r.Run()
+}
+```
+- 修改启动端口`r.Run("80")`
+### Gin的使用方式
+- Gin 支持多种 HTTP 方法的路由定义：
+	- `GET`
+	- `POST`
+	- `PUT`
+	- `DELETE`
+	- `PATCH`
+	- `OPTIONS`
+	- `HEAD`
+	```go
+	r.GET("/get", func(c *gin.Context) {
+    c.JSON(200, gin.H{
+	        "message": "GET request",
+	    })
+	})
+	
+	r.POST("/post", func(c *gin.Context) {
+	    c.JSON(200, gin.H{
+	        "message": "POST request",
+	    })
+	})
+	```
+- Gin获取请求参数
+	- - **查询参数**：`c.Query("key")`
+    - **表单参数**：`c.PostForm("key")`
+    - **路径参数**：`c.Param("key")`
+	```go
+	r.GET("/user", func(c *gin.Context) {
+	    name := c.Query("name")
+	    c.JSON(200, gin.H{
+	        "name": name,
+	    })
+	})
+	
+	r.POST("/user", func(c *gin.Context) {
+	    name := c.PostForm("name")
+	    c.JSON(200, gin.H{
+	        "name": name,
+	    })
+	})
+	
+	r.GET("/user/:id", func(c *gin.Context) {
+	    id := c.Param("id")
+	    c.JSON(200, gin.H{
+	        "id": id,
+	    })
+	})
+	```
+	- Json参数
+	```go
+	var orders struct {  
+	    DeviceId  string `json:"deviceId"`  
+	    Isrunning int    `json:"isrunning"`  
+	}  
+	if err := c.ShouldBind(&orders); err != nil {  
+	    c.JSON(http.StatusBadRequest, gin.H{"error": err.Error()})  
+	    return  
+	}
+	```
+- 分组路由
+
+使用 `r.Group()` 创建路由分组：
+```go
+v1 := r.Group("/")
+{
+    v1.GET("/login", func(c *gin.Context) {
+        c.String(200, "v1 login")
+    })
+    v1.GET("/submit", func(c *gin.Context) {
+        c.String(200, "v1 submit")
+    })
+}
+```
+
+- Gin使用中间件
+```go
+func Logger() gin.HandlerFunc {
+    return func(c *gin.Context) {
+        fmt.Println("Request received")
+        c.Next()
+    }
+}
+
+func main() {
+    r := gin.Default()
+    r.Use(Logger())
+
+    r.GET("/", func(c *gin.Context) {
+        c.JSON(200, gin.H{
+            "message": "Hello, Gin!",
+        })
+    })
+
+    r.Run()
+}
+```
+- 返回多种响应
+	- **JSON**：`c.JSON(code, obj)`
+	- **字符串**：`c.String(code, format, values...)`
+	- **HTML**：`c.HTML(code, name, obj)`
+	- **文件**：`c.File(filepath)`
+```go
+r.GET("/json", func(c *gin.Context) {
+    c.JSON(200, gin.H{
+        "message": "JSON response",
+    })
+})
+
+r.GET("/string", func(c *gin.Context) {
+    c.String(200, "String response")
+})
+
+r.GET("/html", func(c *gin.Context) {
+    c.HTML(200, "index.html", gin.H{
+        "title": "Main website",
+    })
+})
+r.GET("/getfiles", getfiles)
+func getfiles(c *gin.Context) {
+	c.File("./Halloworld.txt")
+}
+```
+### 常用的中间件
+#### 1. **CORS 跨域中间件**
+• **作用**：处理跨域请求，允许前端应用访问 API。
+• **包地址**：`github.com/gin-contrib/cors`
+• **安装**：
+  ```bash
+  go get github.com/gin-contrib/cors
+  ```
+• **示例**：
+  ```go
+  import "github.com/gin-contrib/cors"
+
+  r.Use(cors.New(cors.Config{
+    AllowOrigins:  []string{"https://example.com"},
+    AllowMethods:  []string{"GET", "POST"},
+    AllowHeaders:  []string{"Authorization"},
+  }))
+  ```
+
+#### 2. **JWT 身份验证中间件**
+• **作用**：验证请求的 Token，保护需要登录的接口。
+• **包地址**：`github.com/appleboy/gin-jwt/v2`
+• **安装**：
+  ```bash
+  go get github.com/appleboy/gin-jwt/v2
+  ```
+• **示例**：
+  ```go
+  authMiddleware, _ := jwt.New(&jwt.GinJWTMiddleware{
+    Realm:       "my-app",
+    Key:         []byte("secret-key"),
+    Timeout:     time.Hour,
+  })
+  r.POST("/login", authMiddleware.LoginHandler)
+  r.GET("/protected", authMiddleware.MiddlewareFunc(), func(c *gin.Context) {
+    c.JSON(200, gin.H{"msg": "Authorized"})
+  })
+  ```
+
+#### 3. **限流中间件（Rate Limiter）**
+• **作用**：防止接口被频繁调用（如防止暴力破解）。
+• **包地址**：`github.com/ulule/limiter/v3` + `github.com/ulule/limiter/v3/drivers/middleware/gin`
+• **安装**：
+  ```bash
+  go get github.com/ulule/limiter/v3
+  ```
+• **示例**：
+  ```go
+  import (
+    "github.com/ulule/limiter/v3"
+    "github.com/ulule/limiter/v3/drivers/middleware/gin"
+    "github.com/ulule/limiter/v3/drivers/store/memory"
+  )
+
+  rate := limiter.Rate{
+    Period: 1 * time.Minute,
+    Limit:  100, // 每分钟最多 100 次请求
+  }
+  store := memory.NewStore()
+  limiterMiddleware := gin.NewMiddleware(limiter.New(store, rate))
+  r.Use(limiterMiddleware)
+  ```
+
+#### 4. **GZIP 压缩中间件**
+• **作用**：压缩 HTTP 响应体，减少传输体积。
+• **包地址**：`github.com/gin-contrib/gzip`
+• **安装**：
+  ```bash
+  go get github.com/gin-contrib/gzip
+  ```
+• **示例**：
+  ```go
+  import "github.com/gin-contrib/gzip"
+
+  r.Use(gzip.Gzip(gzip.DefaultCompression))
+  ```

+```bash
+go get github.com/go-redis/redis/v8
+```
+
+---
+
+### 2. 连接 Redis
+```go
+package main
+
+import (
+    "context"
+    "fmt"
+    "github.com/go-redis/redis/v8"
+)
+
+var ctx = context.Background()
+
+func main() {
+    // 创建 Redis 客户端
+    rdb := redis.NewClient(&redis.Options{
+        Addr:     "localhost:6379", // Redis 地址
+        Password: "",              // 密码（没有则为空）
+        DB:       0,               // 默认数据库

+// 向列表尾部添加元素
+rdb.RPush(ctx, "tasks", "task1", "task2")
+
+// 获取列表范围
+tasks, err := rdb.LRange(ctx, "tasks", 0, -1).Result()
+fmt.Println("Tasks:", tasks) // 输出: Tasks: [task1 task2]
+```
+
+#### 集合（Sets）
+```go
+// 添加元素到集合
+client.SAdd("tags", "golang", "redis")
+// 检查元素是否存在
+var exists bool
+exists, err = client.SIsMember("tags", "golang").Result()
+if err != nil {
+	panic(err)
+}
+```
+
+---
+
+### 5. 设置过期时间
+```go
+// 设置键值对，10秒后过期
