Use the strings.HasSuffix function to determine whether a string ends with a specified suffix

Use the strings.HasSuffix function to determine whether a string ends with a specified suffix

In the Go language, we often need to process strings. One of the common needs is to determine whether a string ends with a specific suffix. . In order to achieve this function, you can use the HasSuffix function in the strings package. This article will take you through how to use the HasSuffix function and provide code examples.

strings.HasSuffix function is a very useful function in Go language. It accepts two parameters, the first parameter is the string to be judged, and the second parameter is the suffix to be judged. This function returns a boolean value that returns true if the string ends with the specified suffix, false otherwise.

Here is a simple example using the strings.HasSuffix function:

package main

import (
    "fmt"
    "strings"
)

func main() {
    str := "Hello, World!"
    suffix := "World!"

    if strings.HasSuffix(str, suffix) {
        fmt.Println("字符串以指定的后缀结尾")
    } else {
        fmt.Println("字符串不以指定的后缀结尾")
    }
}

In the above example, we use the strings.HasSuffix function to check whether the string str is suffixed suffixEnd. If yes, output "The string ends with the specified suffix"; if not, output "The string does not end with the specified suffix".

Please note that when using the strings.HasSuffix function, the comparison is case-sensitive. That is, if the suffix to be checked is "world!" instead of "World!", the result will be "String does not end with the specified suffix".

In addition, for some special characters, such as Chinese characters or symbols, the strings.HasSuffix function is also valid.

The following is an example of checking the Chinese character suffix:

package main

import (
    "fmt"
    "strings"
)

func main() {
    str := "你好，世界！"
    suffix := "界！"

    if strings.HasSuffix(str, suffix) {
        fmt.Println("字符串以指定的后缀结尾")
    } else {
        fmt.Println("字符串不以指定的后缀结尾")
    }
}

In the above example, we check whether the string str is suffixed by the Chinese character suffix end. If yes, output "The string ends with the specified suffix"; if not, output "The string does not end with the specified suffix".

Summary: Use the strings.HasSuffix function to easily determine whether a string ends with a specified suffix. Whether it is English strings, Chinese characters or other special characters, the HasSuffix function can work normally. In actual development, we can make full use of this function to simplify the code and improve efficiency.
