golang 读取文件

golang 按行读取文件

file, err := os.Open("app-2019-06-01.log")
    if err != nil {
        log.Fatal(err)
    }
    defer file.Close()
    scanner := bufio.NewScanner(file)
    for scanner.Scan() {
            lineText := scanner.Text()
 
        }

整个读取

b, err := ioutil.ReadFile("app-2019-06-01.log") // just pass the file name
    if err != nil {
        fmt.Print(err)
    }

str := string(b) // convert content to a 'string'

fmt.Println(str) // print the content as a 'string'
