字符串格式截断值

Question

This is going to be a simple question to answer, I am sure of it. I am brand new to Go and I can't figure out what is happening.

package main

import (
    "fmt"
    "bufio"
    "os"
    "strings"
)

func main() {
    fmt.Print("*A basic GoLang/Native example*

")
    fmt.Print("Enter your name:
")

    reader := bufio.NewReader(os.Stdin)
    name, _ := reader.ReadString('
')
    name = strings.TrimSuffix(name, "
")

    fmt.Printf("Hello, %s, how are you?", name)

    reader.ReadString('
')

}

I am removing the newline which is stored in variable name from reading in the user input, but the last Printf statement is truncating Hello, from the line.

I think you are looking for strings.TrimSpace.

To remove the leading and trailing white spaces use this.

Change this line from

name = strings.TrimSuffix(name, " ")

to

name = strings.TrimSpace(name)

Output:

*A basic GoLang/Native example*

Enter your name:
Source Cast
Hello, Source Cast, how are you?

It is working fine for both Windows and Linux.
