Java EE has ServletRequest.getParameterValues().
On non-EE platforms, URL.getQuery() simply returns a string.
What’s the normal way to properly parse the query string in a URL when not on Java EE?
public static Map> getUrlParameters(String url)
throws UnsupportedEncodingException {
Map> params = new HashMap>();
String[] urlParts = url.split("\\?");
if (urlParts.length > 1) {
String query = urlParts[1];
for (String param : query.split("&")) {
String pair[] = param.split("=");
String key = URLDecoder.decode(pair[0], "UTF-8");
String value = "";
if (pair.length > 1) {
value = URLDecoder.decode(pair[1], "UTF-8");
}
List values = params.get(key);
if (values == null) {
values = new ArrayList();
params.put(key, values);
}
values.add(value);
}
}
return params;
}
