我们可以在Go中编码String和url。 Go有带字节数组并转换为字符串编码的Encoder。
解码器获取编码后的值，并将其转换为原始字符串。
Go Base64示例
package main
import "fmt"
import b64 "encoding/base64"
func main() {
data := "Learnfk@12345!@#$%^&*()"
strEncode :=b64.StdEncoding.EncodeToString([]byte(data))
fmt.Println("value to be encode "+data)
fmt.Println("Encoden value: "+strEncode)
