How do I read string argument include & in Go for example this link
$ ./main https://www.youtube.com/watch?v=G3PvTWRIhZA&list=PLQVvvaa0QuDeF3hP0wQoSxpkqgRcgxMqX
without use double quotation (")
$ ./main "https://www.youtube.com/watch?v=G3PvTWRIhZA&list=PLQVvvaa0QuDeF3hP0wQoSxpkqgRcgxMqX"
main.go
package main
import (
"os"
"fmt"
)
func main() {
link := os.Args[1]
fmt.Println(link)
}
$ go build main.go
$ ./main https://www.youtube.com/watch?v=G3PvTWRIhZA&list=PLQVvvaa0QuDeF3hP0wQoSxpkqgRcgxMqX
output will be
Both @JimB and @Adrian are correct, the & needs to be escaped.
If you absolutely must find a workaround, you could opt to not use a command-line argument and rather read input instead to bypass need for escaping.
Example:
package main
import (
"fmt"
)
func main() {
var input string
fmt.Scan(&input)
fmt.Println(input)
}
input:
$ ./main https://www.youtube.com/watch?v=G3PvTWRIhZA&list=PLQVvvaa0QuDeF3hP0wQoSxpkqgRcgxMqX
output:
