It breaks down every component of the url (protocol, domain name, etc). Is
that what you're looking for?
Not really since I just need to process the query string portion to see
if a given param exists or not. I'm using a simple homegrown parser now:
public boolean isParamInUrl(String url, String paramName)
{
int pos = url.indexOf("?");
if ( pos > 0 )
url = url.substring(pos);
String[] paramValues = url.split("&");
if ( paramValues == null )
return false;
for( String paramValue : paramValues )
{
String[] paramAndValue = paramValue.split("=");
if ( paramAndValue == null || paramAndValue.length != 2 )
return false;
if ( paramAndValue[0].equals(paramName) )
return true;
}
return false;
}
The concern is whether this is valid should the URL have complex params
and such based on encoding schemes. I mean, it just splits the url
query string into an array of param-values '&', and then splits that by
'=' without concern for any encoding.
