在[]字符串中分割值

Question

I am a novice in Go programming language. I am writing a code to input from cli for client and pass the values to server for processing. both client and server are residing locally.

code :

package main

import (
    "flag"
    "fmt"
    "strings"
)

func main() {

    text := gettext()
    fmt.Println(text)

    result := strings.Split(text, " ")

    for i := range result {

        fmt.Println(result[i])
    }

}

func gettext() []string {

    flag.Parse()
    text := flag.Args()

    if len(text) < 1 {

        fmt.Println("Please enter radius")

    }

    return text
}

when i run from command line its is giving me following error :cannot use text (type []string) as type string in argument to strings.Split

Basically i want to separately print values from []string .

Can you please let me know how to do it. I tried using strings.split.

Thanks.

You don't need to separate values by " "
The values already separated and your function gettext returns a slice of parameters.
Try this example:

package main

import (
    "flag"
    "fmt"
)

func main() {
    text := gettext()
    fmt.Println(text)

    for i := range text {
        fmt.Println(text[i])
    }
}

func gettext() []string {
    flag.Parse()
    text := flag.Args()

    if len(text) < 1 {
        fmt.Println("Please enter radius")
    }

    return text
}

From the documentation:

func Args() []string
Args returns the non-flag command-line arguments.
