How to implement https request using golang

One of the advantages of golang is its powerful network capabilities. In network communication, more and more servers support https protocol, and accordingly, clients also need to support https requests. This article will introduce how to use golang to implement https requests.

1. Import package

First, we need to import the corresponding package:

import (
    "crypto/tls"
    "net/http"
    "time"
)

Among them, the crypto/tls package provides the implementation of TLS and SSL protocols ; The net/http package provides the implementation of http requests; the time package is used to set the timeout.

2. Create http client

Before initiating an http request, we need to create an http client. When creating an http client, you need to use the RoundTripper interface to set the TLS configuration. The sample code is as follows:

func newHTTPSClient() *http.Client {
    tlsCfg := &tls.Config{
        InsecureSkipVerify: true,
    }

    transport := &http.Transport{
        TLSClientConfig: tlsCfg,
        Proxy:           http.ProxyFromEnvironment,
        DialContext: (&net.Dialer{
            Timeout:   30 * time.Second,
            KeepAlive: 30 * time.Second,
            DualStack: true,
        }).DialContext,
        MaxIdleConns:          100,
        IdleConnTimeout:       90 * time.Second,
        TLSHandshakeTimeout:   10 * time.Second,
        ExpectContinueTimeout: 1 * time.Second,
    }

    return &http.Client{
        Timeout:   time.Second * 30,
        Transport: transport,
    }
}

It should be noted that in the above code, we set InsecureSkipVerify to true, that is, skip certificate verification . If you need to verify the certificate during development, set this value to false.

3. Send http request

After creating the http client, we can use the client to initiate https requests. The sample code is as follows:

func sendHTTPSRequest() {
    client := newHTTPSClient()

    resp, err := client.Get("https://example.com")
    if err != nil {
        log.Fatal(err)
    }
    defer resp.Body.Close()

    body, err := ioutil.ReadAll(resp.Body)
    if err != nil {
        log.Fatal(err)
    }

    fmt.Println(string(body))
}

We use the http.Get method to initiate an https request, and read the returned response body through the ReadAll method in the ioutil package.

4. Summary

This article introduces how to use golang to implement https requests. When implementing https requests, you need to use the TLS and SSL protocol implementations provided by the crypto/tls package and the http request implementation provided by the net/http package. At the same time, you need to pay attention to setting parameters such as timeout and TLS configuration to ensure the reliability and security of the request.
