An article analyzing the escaping methods of strings in Golang

Apr 10, 2023 am 09:02 AM

在Golang中,字符串是一种非常常见的数据类型。而在处理字符串时,有时候需要对一些特殊字符进行转义,才能保证字符串的正确性。本文将介绍Golang中字符串的转义方式。

一、转义符

Golang中使用反斜杠()作为转义的开始。以下是一些常见的转义符及其含义:

转义符 含义
\a 响铃符
\b 退格符
\f 换页符
\n 换行符
\r 回车符
\t 制表符
\v 垂直制表符
\' 单引号
\" 双引号
\ 反斜杠

使用示例:

fmt.Println("hello\nworld") // 输出hello和world分别在不同行
fmt.Println("I'm a man") // 输出I'm a man
fmt.Println("She said: \"Hello!\"") // 输出She said: "Hello!"
fmt.Println("C:\\Windows\\System32\\") // 输出C:\Windows\System32\
Copy after login

二、原始字符串字面量

在Golang中,使用反引号( ` )包括的字符串,称为原始字符串字面量。原始字符串中的转义符将被忽略,字符串中的字符将按照原样输出。

使用示例:

fmt.Println(`hello\nworld`) // 输出hello\nworld
fmt.Println(`I'm a man`) // 输出I'm a man
fmt.Println(`She said: "Hello!"`) // 输出She said: "Hello!"
fmt.Println(`C:\Windows\System32\`) // 输出C:\Windows\System32\
Copy after login

三、Unicode转义

使用Unicode转义可以将任何一个Unicode字符表达成六位的十六进制数字,格式为 \uXXXX 。其中,XXXX代表一个四位的十六进制数字。

使用示例:

fmt.Println("\u0041") // 输出A
Copy after login

四、Rune字面量

在Golang中,rune指表示Unicode字符的类型,具体实现为int32类型。可以使用单引号( ' )包括的字符,称为rune字面量。

使用示例:

fmt.Println('A') // 输出65
fmt.Println('世') // 输出19990
Copy after login

通过对Golang中字符串转义的介绍,我们可以更加方便地处理字符串,避免出现各种错误。

Golang vs. Python: Performance and Scalability Golang vs. Python: Performance and Scalability Apr 19, 2025 am 12:18 AM

Golang is better than Python in terms of performance and scalability. 1) Golang's compilation-type characteristics and efficient concurrency model make it perform well in high concurrency scenarios. 2) Python, as an interpreted language, executes slowly, but can optimize performance through tools such as Cython.

Golang and C  : Concurrency vs. Raw Speed Golang and C : Concurrency vs. Raw Speed Apr 21, 2025 am 12:16 AM

Golang is better than C in concurrency, while C is better than Golang in raw speed. 1) Golang achieves efficient concurrency through goroutine and channel, which is suitable for handling a large number of concurrent tasks. 2)C Through compiler optimization and standard library, it provides high performance close to hardware, suitable for applications that require extreme optimization.

Golang vs. C  : Performance and Speed Comparison Golang vs. C : Performance and Speed Comparison Apr 21, 2025 am 12:13 AM

Golang is suitable for rapid development and concurrent scenarios, and C is suitable for scenarios where extreme performance and low-level control are required. 1) Golang improves performance through garbage collection and concurrency mechanisms, and is suitable for high-concurrency Web service development. 2) C achieves the ultimate performance through manual memory management and compiler optimization, and is suitable for embedded system development.

Golang vs. Python: Key Differences and Similarities Golang vs. Python: Key Differences and Similarities Apr 17, 2025 am 12:15 AM

Golang and Python each have their own advantages: Golang is suitable for high performance and concurrent programming, while Python is suitable for data science and web development. Golang is known for its concurrency model and efficient performance, while Python is known for its concise syntax and rich library ecosystem.

Golang and C  : The Trade-offs in Performance Golang and C : The Trade-offs in Performance Apr 17, 2025 am 12:18 AM

The performance differences between Golang and C are mainly reflected in memory management, compilation optimization and runtime efficiency. 1) Golang's garbage collection mechanism is convenient but may affect performance, 2) C's manual memory management and compiler optimization are more efficient in recursive computing.
