Golang can read binary. In Golang, you can use various methods and technologies to read and process binary data. The method of reading binary is: 1. Use the Open function in the os package to open a file named " data.bin" binary file; 2. Use the Read function in the binary package to read a 32-bit integer in the file; 3. Print out the read integer through the Println function in the fmt package.

Golang is a programming language that can be used to develop efficient, reliable and scalable software applications. One of its design goals is to provide a concise and intuitive way to work with data, including binary data.

In Golang, various methods and techniques can be used to read and process binary data. This includes using functions and types provided in the standard library to read and write binary data, as well as using third-party libraries to handle more complex binary data.

Golang standard library provides some functions to read and write binary data. The most commonly used are the Reader and Writer interfaces in the io package. By implementing these interfaces, various types of binary data can be read and written, including integers, floating point numbers, Boolean values, characters, and byte sequences. In addition, the bufio package provides some functions for efficiently reading and writing binary data, such as Scanner and Writer.

For example, the following code snippet demonstrates how to read and write binary data using functions and types from the Golang standard library:

package main

import (

"encoding/binary"

"fmt"

"os"

)

func main() {

file, err := os.Open("data.bin")

if err != nil {

fmt.Println("Error opening file:", err)

return

}

defer file.Close()

var number int32

err = binary.Read(file, binary.LittleEndian, &number)

if err != nil {

fmt.Println("Error reading binary data:", err)

return

}

fmt.Println("Number:", number)

}

In the above example, we use the os package The Open function in opens a binary file named "data.bin". We then use the Read function from the binary package to read a 32-bit integer from the file, which is represented in little-endian byte order. Finally, we print out the read integer through the Println function in the fmt package.

In addition to the standard library, there are also some third-party libraries that can be used to process more complex binary data. Some of these libraries include the encoding/binary library, which provides functions for reading and writing multibyte data; the bit library, which provides functions for bit operations; and the structs library, which provides functions for parsing binary data into structures.

Summary

Golang provides many methods and techniques to read and process binary data. Whether using functions and types in the standard library or using third-party libraries, you can flexibly handle various types of binary data. This makes Golang a powerful tool for reading, parsing and processing binary data.

How to configure connection pooling for Go database connections? Use the DB type in the database/sql package to create a database connection; set MaxOpenConns to control the maximum number of concurrent connections; set MaxIdleConns to set the maximum number of idle connections; set ConnMaxLifetime to control the maximum life cycle of the connection.

Golang framework vs. Go framework: Comparison of internal architecture and external features Golang framework vs. Go framework: Comparison of internal architecture and external features Jun 06, 2024 pm 12:37 PM

The difference between the GoLang framework and the Go framework is reflected in the internal architecture and external features. The GoLang framework is based on the Go standard library and extends its functionality, while the Go framework consists of independent libraries to achieve specific purposes. The GoLang framework is more flexible and the Go framework is easier to use. The GoLang framework has a slight advantage in performance, and the Go framework is more scalable. Case: gin-gonic (Go framework) is used to build REST API, while Echo (GoLang framework) is used to build web applications.

How to save JSON data to database in Golang? How to save JSON data to database in Golang? Jun 06, 2024 am 11:24 AM

JSON data can be saved into a MySQL database by using the gjson library or the json.Unmarshal function. The gjson library provides convenience methods to parse JSON fields, and the json.Unmarshal function requires a target type pointer to unmarshal JSON data. Both methods require preparing SQL statements and performing insert operations to persist the data into the database.

How to find the first substring matched by a Golang regular expression? How to find the first substring matched by a Golang regular expression? Jun 06, 2024 am 10:51 AM

The FindStringSubmatch function finds the first substring matched by a regular expression: the function returns a slice containing the matching substring, with the first element being the entire matched string and subsequent elements being individual substrings. Code example: regexp.FindStringSubmatch(text,pattern) returns a slice of matching substrings. Practical case: It can be used to match the domain name in the email address, for example: email:="user@example.com", pattern:=@([^\s]+)$ to get the domain name match[1].
