如何将StringText转换为二进制并反之使用Go
问题描述：
i want Convert Text(type=String) To Binary(type=String) And Conversely Using Go
some userfull link : Golang: How to convert String to binary representation & Convert string to binary in Go
but i need another.
i want example convert a text like hello to binary. and next can convert then binary to first text(hello).
var hash_text := hash("hello")//example return *****
var unhash_text := unhash(hash_text);//return hello
like this gist.github.com/hutt/8978333 (using php)
also speed for me is importamt.

Convert each byte individually to its base 2 representation. You can use strconv.ParseUint to convert the base2 back to bytes.
func stringToBase2(s string) string {
var buf bytes.Buffer
for i := 0; i < len(s); i++ {
fmt.Fprintf(&buf, "%08b", s[i])
}
return buf.String()
}
func base2ToString(s string) string {
var out []byte
for i := 0; i+8 <= len(s); i += 8 {
b, err := strconv.ParseUint(s[i:i+8], 2, 8)
if err != nil {
panic(err)
}
out = append(out, byte(b))
}
return string(out)
}
