How to parse this URL in java

Question

I have a URL like this

http://my.my.info/action/doning/something?mailParams=iCgGugAIdMW3CqkYbZ/dGYVqljerVjzbKLvTQCyuosHzxisIrgYf8rcKqRhtn90Z0eVGZ+vx43P4g+umFmddNdDufWv/nDwbCgqBwHs9OYVd5g4VKuFO4jTfF1NiW+KjUi3JubtJT+0F7p+wPHEpTRwJJ+O0eevojx6DioK3cLGejz5UdfIrqzOVNT05TaPKFie4yZxbXfA=

I need it in key value pair not as a query string.

my out put should be

mailParams = iCgGugAIdMW3CqkYbZ/dGYVqljerVjzbKLvTQCyuosHzxisIrgYf8rcKqRhtn90Z0eVGZ+vx43P4g+umFmddNdDufWv/nDwbCgqBwHs9OYVd5g4VKuFO4jTfF1NiW+KjUi3JubtJT+0F7p+wPHEpTRwJJ+O0eevojx6DioK3cLGejz5UdfIrqzOVNT05TaPKFie4yZxbXfA=

i could not parse this string since the above is encoded. I have used URLEncodedUtils to parse this but it returns

mailParams = iCgGugAIdMW3CqkYbZ/dGYVqljerVjzbKLvTQCyuosHzxisIrgYf8rcKqRhtn90Z0eVGZ vx43P4g umFmddNdDufWv/nDwbCgqBwHs9OYVd5g4VKuFO4jTfF1NiW KjUi3JubtJT 0F7p wPHEpTRwJJ O0eevojx6DioK3cLGejz5UdfIrqzOVNT05TaPKFie4yZxbXfA 

which is not at all relevant can some one help me to do this?

Answer 1

If need to split the link to get the parameters

use String#split which takes the regex as a arguments

String link="http://my.my.info/action/doning/something?mailParams=iCgGugAIdMW3CqkYbZ/dGYVqljerVjzbKLvTQCyuosHzxisIrgYf8rcKqRhtn90Z0eVGZ+vx43P4g+umFmddNdDufWv/nDwbCgqBwHs9OYVd5g4VKuFO4jTfF1NiW+KjUi3JubtJT+0F7p+wPHEpTRwJJ+O0eevojx6DioK3cLGejz5UdfIrqzOVNT05TaPKFie4yZxbXfA=";
        String[] mailparams=link.split("\\?");
        System.out.print(mailparams[1]);

You can also Use URL#getQuery

String link="http://my.my.info/action/doning/something?mailParams=iCgGugAIdMW3CqkYbZ/dGYVqljerVjzbKLvTQCyuosHzxisIrgYf8rcKqRhtn90Z0eVGZ+vx43P4g+umFmddNdDufWv/nDwbCgqBwHs9OYVd5g4VKuFO4jTfF1NiW+KjUi3JubtJT+0F7p+wPHEpTRwJJ+O0eevojx6DioK3cLGejz5UdfIrqzOVNT05TaPKFie4yZxbXfA=";
         URL aURL = new URL(link);
        System.out.println( aURL.getQuery());

OUTPUT:

mailParams=iCgGugAIdMW3CqkYbZ/dGYVqljerVjzbKLvTQCyuosHzxisIrgYf8rcKqRhtn90Z0eVGZ+vx43P4g+umFmddNdDufWv/nDwbCgqBwHs9OYVd5g4VKuFO4jTfF1NiW+KjUi3JubtJT+0F7p+wPHEpTRwJJ+O0eevojx6DioK3cLGejz5UdfIrqzOVNT05TaPKFie4yZxbXfA=

Answer 2

Try using java.net.URL

A sample code below.

    URL aURL = new URL("http://my.my.info/action/doning/something?mailParams=iCgGugAIdMW3CqkYbZ/dGYVqljerVjzbKLvTQCyuosHzxisIrgYf8rcKqRhtn90Z0eVGZ+vx43P4g+umFmddNdDufWv/nDwbCgqBwHs9OYVd5g4VKuFO4jTfF1NiW+KjUi3JubtJT+0F7p+wPHEpTRwJJ+O0eevojx6DioK3cLGejz5UdfIrqzOVNT05TaPKFie4yZxbXfA=");

    System.out.println("protocol = " + aURL.getProtocol());
    System.out.println("authority = " + aURL.getAuthority());
    System.out.println("host = " + aURL.getHost());
    System.out.println("port = " + aURL.getPort());
    System.out.println("path = " + aURL.getPath());
    System.out.println("query = " + aURL.getQuery());
    System.out.println("filename = " + aURL.getFile());
    System.out.println("ref = " + aURL.getRef());

URL aURL = null;
try {
    aURL = new URL("http://my.my.info/action/doning/something?mailParams=iCgGugAIdMW3CqkYbZ/dGYVqljerVjzbKLvTQCyuosHzxisIrgYf8rcKqRhtn90Z0eVGZ+vx43P4g+umFmddNdDufWv/nDwbCgqBwHs9OYVd5g4VKuFO4jTfF1NiW+KjUi3JubtJT+0F7p+wPHEpTRwJJ+O0eevojx6DioK3cLGejz5UdfIrqzOVNT05TaPKFie4yZxbXfA=");
} catch (MalformedURLException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

System.out.println(aURL.getQuery());
