How to convert Chinese pinyin and Chinese characters in golang

Note: This article discusses how golang implements the conversion of Chinese pinyin and Chinese characters. If you are not familiar with golang or Chinese, you may need to understand the relevant knowledge first.

In the golang programming language, it is not a difficult problem to realize the mutual conversion between Chinese pinyin and Chinese characters. This is because golang has a rich standard library and third-party libraries, which contain many convenient and practical tool functions and methods.

Below we will take the pinyin library as an example to introduce how to convert Chinese pinyin and Chinese characters in golang.

Preparation work:

1. Install pinyin library

You can use the go command to download and install:

go get -u github.com/mozillazg/go-pinyin

2.Import library

Import the pinyin library into the program:

import "github.com/mozillazg/go-pinyin"

Chinese to Pinyin:

For a Chinese string, we can use the pinyin library to convert it into Pinyin:

// 自定义拼音风格，比如将拼音转换成首字母大写的形式
pinyinArgs := pinyin.NewArgs()
pinyinArgs.Style = pinyin.FirstLetter

// 将中文字符串“中文”转换为拼音“zhōng wén”
pinyinSlice := pinyin.Pinyin("中文", pinyinArgs)
fmt.Println(pinyinSlice)

The above code will output:

[[zh] [ōng] [ ] [w] [én]]

Among them, the conversion result of each Chinese character is a sub-array, such as "中" in "中文" is converted to "[zh]", and "文" is converted For "[w][én]" two subarrays.

If you want to combine Pinyin into a string, you can use the join function:

// 将拼音子数组合并成一个字符串
pinyinStr := strings.Join(pinyinSlice, "-")

fmt.Println(pinyinStr)

The above code will output:

zh-ōng- -w-én

Pinyin to Chinese:

If we want to convert a pinyin string into Chinese characters, we can use the Convert method.

// 自定义拼音风格，该风格会将每个拼音首字母大写
pinyinArgs := pinyin.NewArgs()
pinyinArgs.Style = pinyin.FirstLetter

// 将拼音字符串“zhong-wen”转换为汉字“中文”
hanSlice := pinyin.Pinyin2Han("zhong-wen", pinyinArgs)
fmt.Println(hanSlice)

The above code will output:

[中 文]

If you need to combine the pinyin of the first letter of each Chinese character in the Chinese string into a string, you can use the Convert method of the pinyin library:

// 自定义拼音风格，对于转换结果的每个单词，将其首字母大写
pinyinArgs := pinyin.NewArgs()
pinyinArgs.Style = pinyin.FirstLetter

// 将拼音字符串“zhong-wen”转换为汉字字符串“中文”
hanStr := pinyin.Convert("zhong-wen", pinyinArgs)
fmt.Println(hanStr)

The above code will output:

Zhong Wen

Summary:

This article introduces how to use the pinyin library in golang to realize the mutual conversion of Chinese pinyin and Chinese characters. By using the pinyin library, we can save the time and energy of writing conversion functions ourselves and improve programming efficiency. Of course, not only golang, but also many Chinese pinyin conversion libraries can be used in other programming languages.
