How do you send an HTTP DELETE request in Go?

HTTP DELETE is a method used in the HTTP protocol for sending a request to a server to delete a specified resource. It is one of the most commonly used HTTP methods along with GET, POST, PUT, and PATCH. The DELETE method is used to delete the resource identified by the Request-URI, which can be a specific resource, a collection of resources, or even an entire object. When a DELETE request is sent to the server, the server will remove the specified resource or collection of resources, and return a response to indicate whether the operation was successful or not.
HTTP DELETE request
To send an HTTP DELETE request in Go, you can use the net/http package, which provides a convenient http.NewRequest function to create a new HTTP request with the specified method, URL and body.
Here's an example of how to send an HTTP DELETE request in Go:

Example

package main

import (
    "fmt"
    "net/http"
    "io/ioutil"
)

func main() {
    // create a new HTTP client
    client := &http.Client{}

    // create a new DELETE request
    req, err := http.NewRequest("DELETE", "http://example.com/api/resource/123", nil)
    if err != nil {
        panic(err)
    }

    // send the request
    resp, err := client.Do(req)
    if err != nil {
        panic(err)
    }
    defer resp.Body.Close()

    // read the response body
    body, err := ioutil.ReadAll(resp.Body)
    if err != nil {
        panic(err)
    }

    // print the response body
    fmt.Println(string(body))
}
In this example, we create a new http.Client and use it to send a new http.NewRequest with the DELETE method, the resource URL, and an empty request body. Then we send the request with the client.Do(req) method, which returns a response object that we can read from and then close. Finally, we read the response body with ioutil.ReadAll(resp.Body) and print it to the console.
HTTP DELETE request using GIN
To send an HTTP DELETE request in Go Gin, you can use the DELETE method of the gin.Context object. The DELETE method takes a URL path and a handler function as arguments. Inside the handler function, you can use the context.Request object to create a new HTTP request with the DELETE method, and then send it using the http.Client object.
Here's an example of how to send an HTTP DELETE request in Go Gin:

Example

package main

import (
    "fmt"
    "net/http"

    "github.com/gin-gonic/gin"
)

func main() {
    // create a new router
    r := gin.Default()

    // define a DELETE route
    r.DELETE("/api/resource/:id", func(c *gin.Context) {
        // get the resource ID from the URL parameters
        id := c.Param("id")

        // create a new HTTP client
        client := &http.Client{}

        // create a new DELETE request with the resource ID in the URL path
        req, err := http.NewRequest("DELETE", "http://example.com/api/resource/"+id, nil)
        if err != nil {
            panic(err)
        }

        // send the request
        resp, err := client.Do(req)
        if err != nil {
            panic(err)
        }
        defer resp.Body.Close()

        // set the response status code
        c.Status(resp.StatusCode)
    })

    // start the server
    r.Run(":8080")
}
In this example, we define a new DELETE route with the r.DELETE method and the resource ID as a parameter in the URL path. Inside the handler function, we use the http.NewRequest function to create a new DELETE request with the resource ID in the URL path. Then we send the request using the http.Client object and set the response status code using the c.Status method of the gin.Context object.
HTTP DELETE request using Beego
To send an HTTP DELETE request in Go Beego, you can use the Del method of the beego.Controller object. The Del method takes a URL path as an argument and sends a DELETE request to that URL.
Here's an example of how to send an HTTP DELETE request in Go Beego:

Example

package main

import (
    "github.com/astaxie/beego"
    "net/http"
)

type MyController struct {
    beego.Controller
}

func (c *MyController) Delete() {
    // get the resource ID from the URL parameters
    id := c.Ctx.Input.Param(":id")

    // create a new HTTP client
    client := &http.Client{}

    // create a new DELETE request with the resource ID in the URL path
    req, err := http.NewRequest("DELETE", "http://example.com/api/resource/"+id, nil)
    if err != nil {
        panic(err)
    }

    // send the request
    resp, err := client.Do(req)
    if err != nil {
        panic(err)
    }
    defer resp.Body.Close()

    // set the response status code
    c.Ctx.ResponseWriter.WriteHeader(resp.StatusCode)
}

func main() {
    // create a new controller
    c := &MyController{}

    // define a DELETE route
    beego.Router("/api/resource/:id", c, "delete:Delete")

    // start the server
    beego.Run(":8080")
}

In this example, we define a new controller with a Delete method, which sends a DELETE request to the specified URL path. We also define a DELETE route with the beego.Router method and bind it to the Delete method of the MyController controller.

Inside the Delete method, we get the resource ID from the URL parameters, create a new HTTP client, and send a DELETE request with the resource ID in the URL path using the http.NewRequest and http.Client objects. We set the response status code using the c.Ctx.ResponseWriter.WriteHeader method of the beego.Controller object.
