## 解析 csv
```
in := `first_name,last_name,username
"Rob","Pike",rob
Ken,Thompson,ken
"Robert","Griesemer","gri"
`
r := csv.NewReader(strings.NewReader(in))
//r.Comma = ';' // 指定分隔符
//r.Comment = '#' // 指定注释
for {
record, err := r.Read()
if err == io.EOF {
break
}
if err != nil {
log.Fatal(err)
}
fmt.Println(record)
}
// Output:
// [first_name last_name username]
// [Rob Pike rob]
// [Ken Thompson ken]
// [Robert Griesemer gri]
```
## 数组转 csv
```
records := [][]string{
{"first_name", "last_name", "username"},
{"Rob", "Pike", "rob"},
{"Ken", "Thompson", "ken"},
{"Robert", "Griesemer", "gri"},
}
w := csv.NewWriter(os.Stdout)
w.WriteAll(records) // calls Flush internally
if err := w.Error(); err != nil {
log.Fatalln("error writing csv:", err)
}
```
