go 读写csv文件

package main

import (
    "encoding/csv"
    "fmt"
    "os"
)

func write()  {
    f, err := os.Create("test.csv")
    if err != nil{
        fmt.Println(err)
        return
    }
    defer f.Close()
    var data = make([][]string, 4)
    data[0] = []string{"标题", "作者", "时间"}
    data[1] = []string{"羊皮卷", "鲁迅", "2008"}
    data[2] = []string{"易筋经", "唐生", "665"}

    f.WriteString("xEFxBBxBF")  // 写入一个UTF-8 BOM

    w := csv.NewWriter(f) //创建一个新的写入文件流
    w.WriteAll(data)
    w.Flush()
}

func Read()  {
    f, err := os.Open("test.csv")
    if err != nil{
        fmt.Println(err)

        fmt.Println(err)
        return
    }
    fmt.Println(data)
}

func main() {
    Read()
