golang url transcoding

May 16, 2023 pm 01:18 PM

In Golang, URL is a very important symbol for locating network resources. When using URLs, URL encoding and decoding are involved. URL encoding refers to converting text containing non-ASCII characters or special characters into a URL-safe format, while URL decoding converts this URL-safe text back into Original text.

In Golang, URL encoding and decoding can be implemented using the built-in net/url package. Next, we will introduce in detail how to use the net/url package in Golang to implement URL encoding and decoding.

URL encoding

In Golang, URL encoding can be implemented using the Escape and QueryEscape functions in the net/url package. Below is how to use the two functions.

  1. Escape function

The Escape function is mainly used to encode text into a URL-safe format, which converts spaces, special characters and non-ASCII characters into, The format of %xx and %uxxxx.

import "net/url"

text := "This is a test 中文"
encodedText := url.Escape(text)
fmt.Println(encodedText) // This%20is%20a%20test%20%E4%B8%AD%E6%96%87
Copy after login
  1. QueryEscape function

The QueryEscape function is mainly used to encode text in URL request parameters, where it separates spaces, special characters and non-ASCII characters. Convert to %xx and %uxxxx formats. At the same time, the QueryEscape function is equivalent to the Escape function and they return the same results.

import "net/url"

text := "This is a test 中文"
encodedText := url.QueryEscape(text)
fmt.Println(encodedText) // This+is+a+test+%E4%B8%AD%E6%96%87
Copy after login

URL decoding

In Golang, URL decoding can be implemented using the Unescape and QueryUnescape functions in the net/url package, which correspond to the Escape and QueryEscape functions respectively.

  1. Unescape function

The Unescape function is mainly used to convert encoded text into original text, which will convert the formats of %xx and %uxxxx into spaces respectively. , the corresponding ASCII characters and the corresponding UniCode characters.

import "net/url"

encodedText := "This%20is%20a%20test%20%E4%B8%AD%E6%96%87"
text, err := url.Unescape(encodedText)
if err != nil {
    panic(err)
}
fmt.Println(text) // This is a test 中文
Copy after login
  1. QueryUnescape function

The QueryUnescape function is mainly used to decode the encoding in the URL request parameters into original text, which will convert the formats of %xx and %uxxxx respectively. Convert to spaces, corresponding ASCII characters and corresponding UniCode characters. At the same time, the QueryUnescape function is equivalent to the Unescape function and they return the same results.

import "net/url"

encodedText := "This+is+a+test+%E4%B8%AD%E6%96%87"
text, err := url.QueryUnescape(encodedText)
if err != nil {
    panic(err)
}
fmt.Println(text) // This is a test 中文
Copy after login

Summary

In Golang, URL encoding and decoding can be easily achieved using the built-in net/url package. Especially in network applications, URL encoding and decoding are very commonly used and play a great role in network security, data transmission and other aspects. Therefore, it is very important for Golang developers to be proficient in using URL encoding and decoding technology in Golang.
