<p>Hello Guys,</p>
<p>do you know a way to parse a binary string into a readable string?
Example:
"01010100 01100101 01110011 01110100" into "Test"</p>
<hr/>**评论：**<br/><br/>popillol: <pre><p>Not sure if this can be shortened, but <a href="https://play.golang.org/p/0PLBonPTm9u" rel="nofollow">here's an option</a></p>
<pre><code>package main
import (
"fmt"
"strconv"
"strings"
)
func main() {
input := "01010100 01100101 01110011 01110100"
b := make([]byte, 0)
for _, s := range strings.Fields(input) {
n, _ := strconv.ParseUint(s, 2, 8)
b = append(b, byte(n))
}
fmt.Println(string(b))
}

<p><a href="https://play.golang.org/p/V1JPZ1zI8Pb" rel="nofollow">Here is my solution, based on yours.</a></p>
<pre><code>package main
import (
"fmt"
"regexp"
"strconv"
)
func main() {
input := "01010100011001010111001101110100"
r, _ := regexp.Compile("[0|1]{8}")
match := r.FindAllString(input, -1)
b := make([]byte, 0)
for _, s := range match {
n, _ := strconv.ParseUint(s, 2, 8)
b = append(b, byte(n))
}
fmt.Println(string(b))
}

Which may be more memory, but easier to follow.</p>
<pre><code>func main() {
i := new(big.Int)
i.SetString("0b01010100011001010111001101110100", 0) // inferred
fmt.Println(string(i.Bytes()))
}
