初学Golang就记一下go语言的文件操作 Read File func main(){ rw,err := os.Open("") if err != nil { panic(err) } defer rw.Close() rb := bufio.NewReader(rw) for { line, _, err := rb.ReadLine() if err == io.EOF { break } //do something fmt.Println(string(line)) } } ...
func (b *Reader) ReadLine() (line []byte, isPrefixbool, err error) 完整示例 package main import ("bufio""fmt""io""os") func main() {//info := "# 人员名单\r\n- 刘备刘玄德\r\n- 关羽关云长\r\n- 张飞张翼德"path :="nameList.md"//writeFile(info,path)readFile(path) } func ...
fmt.Println("一共有", totLine, "行内容") break } } 创建文件--Create 1 2 3 4 5 6 7 //创建文件 //func Create(name string) (*File, error) newFile, err := os.Create("demo.txt") defer newFile.Close() if err != nil { panic(err) } 获取文件的信息--Stat 1 2 3 4 5 6 ...
