GoFrame v2 development skill. Use only when the target Go project uses or is explicitly adopting GoFrame v2: the nearest go.mod requires github.com/gogf/gf/v2, existing Go files import github.com/gogf/gf/v2 or any github.com/gogf/gf/v2/... component package, or the user asks to scaffold, migrate, or build with GoFrame. Trigger for GoFrame-backed Go work such as APIs/controllers/services, middleware, routing/config, ORM/DAO/DO/entity/database operations, gf CLI/codegen, HTTP/gRPC services, and microservice conventions. Do not trigger for generic Go projects without GoFrame evidence, frontend-only work, shell scripts, or unrelated infrastructure tasks.

gudp 模块提供了非常简便易用的 gudp.Conn 链接操作对象。

使用方式:

import "github.com/gogf/gf/v2/net/gudp"

接口文档: https://pkg.go.dev/github.com/gogf/gf/v2/net/gudp

基本介绍

gudp.Conn 的操作绝大部分类似于 gtcp 的操作方式(大部分的方法名称也相同),但由于 UDP 是面向非连接的协议,因此 gudp.Conn(底层通信端口)也只能完成最多一次数据写入和读取,客户端下一次再与目标服务端进行通信的时候,将需要创建新的 Conn 对象进行通信。

使用示例

package main

import (
    "context"
    "fmt"
    "time"

    "github.com/gogf/gf/v2/frame/g"
    "github.com/gogf/gf/v2/net/gudp"
    "github.com/gogf/gf/v2/os/gtime"
)

func main() {
    var (
        ctx    = context.Background()
        logger = g.Log()
    )
    // Server
    go gudp.NewServer("127.0.0.1:8999", func(conn *gudp.ServerConn) {
        defer conn.Close()
        for {
            data, addr, err := conn.Recv(-1)
            if len(data) > 0 {
                if err = conn.Send(append([]byte("> "), data...), addr); err != nil {
                    logger.Error(ctx, err)
                }
            }
            if err != nil {
                logger.Error(ctx, err)
            }
        }
    }).Run()

    time.Sleep(time.Second)

    // Client
    for {
        if conn, err := gudp.NewClientConn("127.0.0.1:8999"); err == nil {
            if b, err := conn.SendRecv([]byte(gtime.Datetime()), -1); err == nil {
                fmt.Println(string(b), conn.LocalAddr(), conn.RemoteAddr())
            } else {
                logger.Error(ctx, err)
            }
            conn.Close()
        } else {
            logger.Error(ctx, err)
        }
        time.Sleep(time.Second)
    }
}

该示例与 gtcp.Conn 中的通信示例类似,不同的是,客户端与服务端无法保持连接,每次通信都需要创建的新的连接对象进行通信。

执行后,输出结果如下:

    The skill provides a comprehensive development guide and code examples for the GoFrame v2 framework. While highly informative for Go developers, it contains several examples with hardcoded placeholder secrets, tokens, and specific local file paths to sensitive configuration files (like Kubernetes credentials). These elements are provided for demonstration purposes but represent insecure practices if used in production without modification.

README badge for gogf/skills

Provides instruction and conventions for developing with GoFrame v2, a modular Go framework for building HTTP and gRPC services, microservices, and database operations using its ORM, CLI tooling, and project scaffolding. Use this skill when the target project has GoFrame v2 as a dependency or when the user requests scaffolding, migrations, or service development with GoFrame conventions.

Generated from the current SKILL.md.

When should I use this skill?
Use this skill only when your Go project uses GoFrame v2, indicated by github.com/gogf/gf/v2 in go.mod or imports. Do not use for generic Go projects, frontend work, or infrastructure tasks unrelated to GoFrame.
Should I manually set created_at and updated_at fields?
No. GoFrame automatically writes created_at on insert and updated_at on insert/update/save. Manually setting these fields is redundant and violates project conventions.
What should I use for database operations instead of g.Map?
Always use DO objects from internal/model/do/. DO struct fields are interface{}, unset fields remain nil and are automatically ignored by the ORM.
How does soft delete work in GoFrame?
Call Delete() on the DAO; GoFrame automatically converts it to UPDATE SET deleted_at = NOW(). Queries automatically filter out soft-deleted rows without requiring manual WhereNull conditions.
Where should I implement business logic?
Implement business logic directly in the service/ directory. Do not use the logic/ directory unless explicitly requested.
