- 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**。

# 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))
|
||||
```

### 1. 安装 Redis 客户端库
|
||||
```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
|
||||
})
|
||||
|
||||
// 检查连接
|
||||
pong, err := rdb.Ping(ctx).Result()
|
||||
if err != nil {
|
||||
panic(err)
|
||||
}
|
||||
fmt.Println("Connected to Redis:", pong)
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 3. 基本操作
|
||||
|
||||
#### 设置键值对
|
||||
```go
|
||||
// 设置键为 "name"，值为 "Alice"
|
||||
err := rdb.Set(ctx, "yzk_study@163.com", "123456", 600).Err()
|
||||
if err != nil {
|
||||
panic(err)
|
||||
}
|
||||
```
|
||||
|
||||
#### 获取值
|
||||
```go
|
||||
val, err := rdb.Get(ctx, "yzk_study@163.com").Result()
|
||||
if err != nil {
|
||||
panic(err)
|
||||
}
|
||||
fmt.Println("His Verification code", val) // 输出: name: Alice
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 4. 数据结构操作
|
||||
|
||||
#### 哈希（Hashes）
|
||||
```go
|
||||
client.HMSet("user:1", map[string]interface{}{"name": "Bob", "age": 30})
|
||||
// 获取哈希字段
|
||||
age, err := client.HGet("user:1", "age").Int()
|
||||
if err != nil {
|
||||
panic(err)
|
||||
}
|
||||
fmt.Println("User age:", age) // 输出: User age: 30
|
||||
```
|
||||
|
||||
#### 列表（Lists）
|
||||
```go
|
||||
// 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
|
||||
rdb.Set("temp_key", "expiring soon", 10*time.Second)
|
||||
|
||||
// 单独设置过期时间
|
||||
rdb.Expire("temp_key", 10*time.Second)
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 6. 删除键
|
||||
```go
|
||||
rdb.Del("name")
|
||||
```
|
||||
