千万不要用window自带文本编辑器编辑配置文件或者代码

1 引言html

用windows自带的text文本在最前面会带入看不到的BOM,致使异常mysql

2 代码sql

package main

import (
	"strings"
	"fmt"
)

func main(){
	line := "// mysql数据库连接配置"
	if strings.EqualFold(line[:2], "//"){
		fmt.Println("this is comment")
	}else{
		fmt.Println("this is not comment")
	}
}

运行结果以下:数据库

# command-line-arguments
test\test\testFilterRemark.go:17:11: invalid BOM in the middle of the file

Compilation finished with exit code 2  

若是改成:(在文本上是看不出差别性的)windows

func main(){
	line := "// mysql数据库连接配置"
	if strings.EqualFold(line[:2], "//"){
		fmt.Println("this is comment")
	}else{
		fmt.Println("this is not comment")
	}
}

运行结果以下:bash

this is comment

Process finished with exit code 0 

3.扩展资料this
