How does the golang framework integrate with other languages ​​or technologies?

The Go framework can be integrated with other languages ​​and technologies by: Interacting with C or C++ code using Go FFI. Use API wrappers to interact with APIs created in other languages. Use message queues to transfer information between different languages ​​or processes.

How to integrate the Go framework with other languages ​​and technologies

The powerful portability and interoperability of the Golang framework make It integrates easily with other languages ​​and technologies. Here are a few common ways to do this:

Using Go FFI

The Go Foreign Function Interface (FFI) allows Go programs to interact with programs written in C or C++ code to interact. This can be achieved by using the Cgo package, which allows you to call C functions and access C structures from Go code.

Case: Integrating with Rust

import "C"

func main() {
    // 调用 Rust 函数
    fmt.Printf("平方根：%v\n", C.sqrt(25))

    // 访问 Rust 结构
    type Point C.struct_Point
    p := Point{X: 10, Y: 20}
    fmt.Printf("点：(%v, %v)\n", p.X, p.Y)
}

Using API wrappers

API wrappers are another way to communicate across languages choice. You can create an API in another language and then write a wrapper in Go that allows Go programs to interact with the API.

Case: Integrating with Python

import (
    "github.com/go-python/gopython3"
    "github.com/go-python/gopython3/run"
)

func main() {
    // 初始化 Python 解释器
    python := run.Main()

    // 调用 Python 函数
    f, _ := python.Module("math").Attr("factorial")
    r, _ := f.Call(python.Int(5))
    fmt.Printf("阶乘：%v\n", r)
}

Using message queue

Message queue provides a way to transmit information and store it in different A method for communicating between languages ​​or processes. You can write a producer in Go to push messages to a queue, and a consumer in another language to receive and process those messages.

Case: Integrating with Node.js

Golang:

import (
    "github.com/go-amqp/go-amqp"
)

func main() {
    conn, err := amqp.Dial(...)
    if err != nil {
        panic(err)
    }
    ch, err := conn.Channel(...)
    if err != nil {
        panic(err)
    }

    // 发布消息
    msg := amqp.Publishing{
        Body: []byte("Hello from Go!"),
    }
    err = ch.Publish(...)

    ch.Close()
    conn.Close()
}

Node.js:

const amqp = require('amqplib');

const main = async () => {
    const conn = await amqp.connect(...);
    const ch = await conn.createChannel();

    // 订阅消息
    ch.consume('my_queue', (msg) => {
        const data = msg.content.toString();
        console.log(data);
    });
};

main();
