The use of HttpRouter routing of Gin's Go language web rapid development framework

A high-performance router library is used inside the Gin framework calledhttprouter, this is a very efficient and lightweight HTTP request router. It can quickly parse and process request paths, support dynamic parameter matching, and is ideal for building high-performance web applications.

Main features

• high performance：httprouterIt is a very efficient router and has significantly better performance than most other Go language routers.
• Dynamic parameter matching: Support dynamic routing parameters, such as/user/:idCan match/user/123Such a path.
• A simple interface: Simple to use, clear and easy to read.

Basic use

Here is a framework using Gin andhttprouterBasic examples:

• First, make sure you have the Gin framework installed:

go get -u /gin-gonic/gin

• Then you can use Gin andhttprouterTo write your web server. Here is a complete code example:

package main

import (
    "/gin-gonic/gin"
    "net/http"
)

func main() {
    // Create a default Gin router    r := ()

    // Define the root routing processing function    ("/", func(c *) {
        (, "Welcome to the Go Web homepage! The processor is: indexHandler!")
    })

    // Define/hi routing processing function    ("/hi", func(c *) {
        (, "Welcome to the Go Web Welcome Page! The processor is: hiHandler!")
    })

    // Define /hi/web routing processing function    ("/hi/web", func(c *) {
        (, "Welcome to the Go Web Welcome Page! The processor is: webHandler!")
    })

    // Start the HTTP server and listen to port 8083    if err := (":8083"); err != nil {
        panic(err)
    }
}

Dynamic routing parameters

Gin UsehttprouterSupport dynamic parameter matching, the following is an example containing dynamic parameters:

package main

import (
    "/gin-gonic/gin"
    "net/http"
)

func main() {
    // Create a default Gin router    r := ()

    // Define a route with dynamic parameters    ("/user/:id", func(c *) {
        id := ("id")
        (, "User ID: %s", id)
    })

    // Start the HTTP server and listen to port 8083    if err := (":8083"); err != nil {
        panic(err)
    }
}

In this example, when accessing/user/123When the response will beUser ID: 123。

Routing Group

Gin also supports routing groups, making it more convenient to manage complex routing. Here is an example using a routing group:

package main

import (
    "/gin-gonic/gin"
    "net/http"
)

func main() {
    // Create a default Gin router    r := ()

    // Create a routing group    v1 := ("/v1")
    {
        ("/users", func(c *) {
            (, "Get user list")
        })

        ("/users/:id", func(c *) {
            id := ("id")
            (, "Get user details, ID: %s", id)
        })
    }

    // Start the HTTP server and listen to port 8083    if err := (":8083"); err != nil {
        panic(err)
    }
}

In this example, a/v1The starting route group contains two routes:/v1/usersand/v1/users/:id。

Summarize

Gin framework is efficient by usinghttprouterProvides powerful routing functions, suitable for building high-performance web applications. Whether it is simple static routing or complex dynamic routing and routing groups, Gin can easily handle it. Through these features, you can quickly build powerful and efficient web applications.
