如果URL里面要包含特殊的字符和空格,你需要对其进行编码,你需要编码和解码。下面的代码演示了如何进行编码和解码。
import java.net.*;
public class URL_Encoder_Decoder{
public static void main(String[] args){
String sir="@sir de caractere@,nr. 1290 'paragraf 3'";
try{
String sir_codat=URLEncoder.encode(sir,"UTF-8");
String sir_decodat=URLDecoder.decode(sir_codat,"UTF-8");
System.out.println(sir);
System.out.println(sir_codat);
System.out.println(sir_decodat);
}catch(java.io.UnsupportedEncodingException e)
{System.out.println("Eroare:"+e.getMessage());}
}
}
下面是输出结果:
@sir de caractere@,nr. 1290 'paragraf 3'
%40sir+de+caractere%40%2Cnr.+1290+%27paragraf+3%27
@sir de caractere@,nr. 1290 'paragraf 3'
