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.

gtcp 模块支持 TLS 加密通信服务端及客户端,在对安全要求比较高的场景中非常必要。 TLS 服务端创建可以通过 NewServerTLS 或者 NewServerKeyCrt 方法实现。 TLS 客户端创建可以通过 NewConnKeyCrt 或者 NewConnTLS 方法实现。

使用示例:

https://github.com/gogf/gf/tree/master/.example/net/gtcp/tls

package main

import (
    "fmt"
    "github.com/gogf/gf/v2/frame/g"
    "github.com/gogf/gf/v2/net/gtcp"
    "github.com/gogf/gf/v2/util/gconv"
    "time"
)

func main() {
    address := "127.0.0.1:8999"
    crtFile := "server.crt"
    keyFile := "server.key"
    // TLS Server
    go gtcp.NewServerKeyCrt(address, crtFile, keyFile, func(conn *gtcp.Conn) {
        defer conn.Close()
        for {
            data, err := conn.Recv(-1)
            if len(data) > 0 {
                fmt.Println(string(data))
            }
            if err != nil {
                // if client closes, err will be: EOF
                g.Log().Error(err)
                break
            }
        }
    }).Run()

    time.Sleep(time.Second)

    // Client
    conn, err := gtcp.NewConnKeyCrt(address, crtFile, keyFile)
    if err != nil {
        panic(err)
    }
    defer conn.Close()
    for i := 0; i < 10; i++ {
        if err := conn.Send([]byte(gconv.String(i))); err != nil {
            g.Log().Error(err)
        }
        time.Sleep(time.Second)
        if i == 5 {
            conn.Close()
            break
        }
    }

    // exit after 5 seconds
    time.Sleep(5 * time.Second)
}

执行后,可以看到客户端执行时报错:

panic: x509: certificate has expired or is not yet valid

那是因为我们的证书是手动创建的,并且已经过期了,为了演示方便,我们在客户端代码中去掉客户端对证书的校验。

package main

import (
    "fmt"
    "github.com/gogf/gf/v2/net/gtcp"
    "github.com/gogf/gf/v2/util/gconv"
    "time"
)

func main() {
    address := "127.0.0.1:8999"
    crtFile := "server.crt"
    keyFile := "server.key"
    // TLS Server
    go gtcp.NewServerKeyCrt(address, crtFile, keyFile, func(conn *gtcp.Conn) {
        defer conn.Close()
        for {
            data, err := conn.Recv(-1)
            if len(data) > 0 {
                fmt.Println(string(data))
            }
            if err != nil {
                // if client closes, err will be: EOF
                g.Log().Error(err)
                break
            }
        }
    }).Run()

    time.Sleep(time.Second)

    // Client
    tlsConfig, err := gtcp.LoadKeyCrt(crtFile, keyFile)
    if err != nil {
        panic(err)
    }
    tlsConfig.InsecureSkipVerify = true

    conn, err := gtcp.NewConnTLS(address, tlsConfig)
    if err != nil {
        panic(err)
    }
    defer conn.Close()
    for i := 0; i < 10; i++ {
        if err := conn.Send([]byte(gconv.String(i))); err != nil {
            g.Log().Error(err)
        }
        time.Sleep(time.Second)
        if i == 5 {
            conn.Close()
            break
        }
    }

    // exit after 5 seconds
    time.Sleep(5 * time.Second)
}

执行后,终端输出结果为:

1
2
3
4
5
2019-06-05 00:13:12.488 [ERRO] EOF
Stack:
1. /Users/john/Workspace/Go/GOPATH/src/github.com/gogf/gf/v2/geg/net/gtcp/tls/gtcp_server_client.go:25

其中客户端在 5 秒后关闭了连接,因此服务端在接收数据时获取到了一个 EOF 错误,这种错误在正式使用中我们直接忽略,报错时服务端直接关闭客户端连接即可。

    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

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.
