What did you do?
when i rename uploaded filenames, codes below
package main
import (
"fmt"
"regexp"
)
func main () {
var filename = "abc.123.txt"
var pattern = regexp.MustCompile("^(.+?)\\.([^\\.]+)$")
fmt.Println(pattern.ReplaceAllString(filename, "$1_.$2"))
}
What did you see happen?
output result: .txt
fmt.Println(pattern.ReplaceAllString(filename, "$1000.$2"))
the result unchanged
What did you expect to see?
it seems that golang can't get group no and strings
when i try this replacement in javascript and c#, the out is "abc.123000.txt", which is my expected result
