Golang : Get remaining text such as id or filename after last segment in URL path
Problem:
Retrieving the last segment/part or the remaining text after a slash in the URL or filename in a path can be challenging for newbies in programming. Such as:
123456
from //www.socketloop.com/123456
or
image.png
from c:\windows\image.png
How to extract the desired information from an URL or file path?
Solution:
This is known as extracting the base of a URL or file path. Use the path
package base()
function to extract the last segment or remaining text after the last slash.
Here you go!
package main
import (
"fmt"
"path"
"path/filepath"
)
func main() {
url := "http://www.abcdef.com/12345678"
base := path.Base(url)
fmt.Println(base)
// NOTE: filepath.Base() will WORK with `\`
// provided this program runs on Windows platform
// if this program executes on Non-windows or play.golang.org
// it will show the entire string instead of
// the desire image.exe
// IT IS NOT A BUG!
windowsFilePath := `c:\windows\image.exe`
imageFile := filepath.Base(windowsFilePath)
fmt.Println(imageFile)
}
Output:
12345678
image.exe
