Implemented in Go: Practical tips for getting timestamps
Golang practice: timestamp acquisition skills, specific code examples are required
Abstract: In Golang development, processing timestamps is a common requirement. This article will help readers better obtain and process timestamps in Golang through some practical tips. Specifically, it includes getting the current timestamp, converting the timestamp to time format, converting time format to timestamp, etc. This article will illustrate the specific implementation of these techniques through code examples.
1. Get the current timestamp
In Golang, you can use the Unix() function under the time package to get the current timestamp. The following is a sample code:
package main import ( "fmt" "time" ) func main() { timestamp := time.Now().Unix() fmt.Println("当前时间戳是:", timestamp) }
Run the above code to get the current timestamp.
2. Convert timestamp to time format
If we need to convert a timestamp into a specific time format, we can use the Unix() function and Format() function under the time package. The following is a sample code:
package main import ( "fmt" "time" ) func main() { timestamp := time.Now().Unix() timeFormat := time.Unix(timestamp, 0).Format("2006-01-02 15:04:05") fmt.Println("当前时间戳对应的时间是:", timeFormat) }
In the above sample code, we first obtain the current timestamp, and then use the Unix() function to convert the timestamp into time format. Finally, use the Format() function to convert the time format to the specified time format (in this example, we are using the "2006-01-02 15:04:05" format). Run the above code to get the specific time corresponding to the current timestamp.
3. Convert time format to timestamp
If we need to convert a time in a specific format into a timestamp, we can use the Parse() function and Unix() function under the time package. The following is a sample code:
package main import ( "fmt" "time" ) func main() { timeFormat := "2021-03-15 10:30:00" parseTime, _ := time.Parse("2006-01-02 15:04:05", timeFormat) timestamp := parseTime.Unix() fmt.Println("时间", timeFormat, "对应的时间戳是:", timestamp) }
In the above sample code, we first define a specific time format (in this example, we are using the "2021-03-15 10:30:00" format ). Then, use the Parse() function to convert the time format to Golang’s internal time type. Finally, use the Unix() function to convert the time type to a timestamp. Run the above code to get the timestamp corresponding to the specified time.
Conclusion:
Through the introduction of the above example code, we can see that it is not difficult to obtain and process timestamps in Golang. With the help of functions under the time package, we can easily implement functions such as obtaining timestamps, converting timestamps to time formats, and converting time formats to timestamps. These techniques can help us better handle time-related business needs in actual development.
However, it should be noted that when using timestamps, time zone issues must be considered. Time-related functions in Golang use the UTC time zone by default. If you need to process times in other time zones, you need to use the functions under the time package to perform corresponding conversions.
I hope readers can better understand and apply timestamp acquisition techniques in Golang through the introduction of this article. At the same time, we also hope that readers can flexibly use these techniques according to their actual needs to improve development efficiency.

Go uses the "encoding/binary" package for binary encoding and decoding. 1) This package provides binary.Write and binary.Read functions for writing and reading data. 2) Pay attention to choosing the correct endian (such as BigEndian or LittleEndian). 3) Data alignment and error handling are also key to ensure the correctness and performance of the data.

Go's bytes package is mainly used to efficiently process byte slices. 1) Using bytes.Buffer can efficiently perform string splicing to avoid unnecessary memory allocation. 2) The bytes.Equal function is used to quickly compare byte slices. 3) The bytes.Index, bytes.Split and bytes.ReplaceAll functions can be used to search and manipulate byte slices, but performance issues need to be paid attention to.

The byte package provides a variety of functions to efficiently process byte slices. 1) Use bytes.Contains to check the byte sequence. 2) Use bytes.Split to split byte slices. 3) Replace the byte sequence bytes.Replace. 4) Use bytes.Join to connect multiple byte slices. 5) Use bytes.Buffer to build data. 6) Combined bytes.Map for error processing and data verification.

Go's encoding/binary package is a tool for processing binary data. 1) It supports small-endian and large-endian endian byte order and can be used in network protocols and file formats. 2) The encoding and decoding of complex structures can be handled through Read and Write functions. 3) Pay attention to the consistency of byte order and data type when using it, especially when data is transmitted between different systems. This package is suitable for efficient processing of binary data, but requires careful management of byte slices and lengths.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
