如何从Golang中的字符串中修剪"["char

Question

可能是一个愚蠢的事情,但有点卡在它上面......

无法修剪"["字符串中的字符,我尝试输出的内容:

package main

import (
    "fmt"
    "strings"
)

func main() {
    s := "this[things]I would like to remove"
    t := strings.Trim(s, "[")

    fmt.Printf("%s\n", t)   
}

// output: this[things]I would like to remove

去操场

还尝试了所有这些,没有成功:

s := "this [ things]I would like to remove"
t := strings.Trim(s, " [ ")
// output: this [ things]I would like to remove


s := "this [ things]I would like to remove"
t := strings.Trim(s, "[")
// output: this [ things]I would like to remove

没有用.我在这里错过了什么？

你错过了阅读文档.strings.Trim():

func Trim(s string, cutset string) string

Trim返回字符串s的一个片段,其中包含cutset中包含的所有前导和尾随 Unicode代码点.

[输入中的字符不在前导位置,也不在尾随位置,它位于中间,因此strings.Trim()- 行为良好 - 不会将其删除.

尝试strings.Replace()改为:

s := "this[things]I would like to remove"
t := strings.Replace(s, "[", "", -1)
fmt.Printf("%s\n", t)   

输出(在Go Playground上试试):

thisthings]I would like to remove
