Curl and Golang are both very popular programming languages. Although they are different, they both have their own advantages. In practical applications, we sometimes need to convert Curl code into Golang code to better implement specific functions and project requirements. This article will introduce how to convert Curl code into Golang code.

  1. Characteristics and applications of Curl

Curl is a command line tool widely used in network programming and supports a variety of network protocols, such as HTTP, FTP, SMTP, etc. . It can send network requests of different protocols through the command line and return results. Due to its simplicity of use and powerful functions, Curl is widely used in server-side development, web development, and mobile development.

The following is an example of Curl sending an HTTP request:

curl -X POST http://example.com/user/login -d "username=admin&password=123456"
Copy after login
  1. Features and applications of Golang

Golang is a new programming language, although It is still relatively young compared to other languages, but due to its support for high concurrency, concise code, and high efficiency, Golang has gradually become popular in recent years and has become the programming language of choice for many large enterprises.

Here is an example of Golang sending an HTTP request:

client := &http.Client{}
req, err := http.NewRequest("POST", "http://example.com/user/login", strings.NewReader("username=admin&password=123456"))
if err != nil {
  log.Fatal(err.Error())
}
req.Header.Set("Content-Type", "application/x-www-form-urlencoded")
res, err := client.Do(req)
if err != nil {
  log.Fatal(err.Error())
}
defer res.Body.Close()
Copy after login
  1. Curl conversion to Golang

In order to convert Curl code into Golang code, we need First understand some differences between Curl and Golang. Golang uses the standard library to implement HTTP requests and is object-oriented, while Curl performs network requests through the command line and is not object-oriented.

Here are the steps to convert Curl code to Golang code:

  1. Create an HttpClient object
client := &http.Client{}
Copy after login
  1. Create HTTP request
req, err := http.NewRequest("POST", "http://example.com/user/login", strings.NewReader("username=admin&password=123456"))
Copy after login
  1. Set request header information
req.Header.Set("Content-Type", "application/x-www-form-urlencoded")
Copy after login
  1. Send HTTP request and receive response
res, err := client.Do(req)
if err != nil {
  log.Fatal(err.Error())
}
defer res.Body.Close()
Copy after login
  1. Process the response result
body, err := ioutil.ReadAll(res.Body)
if err != nil {
    log.Fatal(err.Error())
}
fmt.Println(string(body))
Copy after login

Through the above steps, we can convert Curl commands into equivalent Golang code.

  1. Summary

This article introduces how to convert Curl code into Golang code, which is suitable for HTTP requests in network programming. Both Curl and Golang have their unique advantages and applicable scenarios in practical applications. I hope this article can help readers better understand Curl and Golang and provide assistance for development work.
