How to get request parameter as a HashMap

I want my server to be able to pass a GET suh as request:

 http://example.com/?a[foo]=1&a[bar]=15&b=3

And when I get the param 'a' request, it should be parsed as a HashMap like this:

{'foo':1, 'bar':15}

EDIT: Well, to be clear, here is what I am trying to do, but in Java instead of PHP:

Pass array with keys via HTTP GET

Any ideas how to do this?

There is no standard way to do this.

Wink supports javax.ws.rs.core.MultivaluedMap. Therefore, if you send something like http://example.com/?a=1&a=15&b=3, you will receive: key avalues ​​1, 15; key bvalue 3.

If you need to parse something like ?a[1]=1&a[gv]=15&b=3, you need to take javax.ws.rs.core.MultivaluedMap.entrySet()and perform additional parsing of the keys.

, ( , ):

String getArrayParameter(String key, String index,  MultivaluedMap<String, String> queryParameters) {
    for (Entry<String, List<String>> entry : queryParameters.entrySet()) {
        String qKey = entry.getKey();
        int a = qKey.indexOf('[');
        if (a < 0) {
            // not an array parameter
            continue;
        }
        int b = qKey.indexOf(']');
        if (b <= a) {
            // not an array parameter
            continue;
        }
        if (qKey.substring(0, a).equals(key)) {
            if (qKey.substring(a + 1, b).equals(index)) {
                return entry.getValue().get(0);
            }
        }
    }
    return null;
}

:

@GET
public void getResource(@Context UriInfo uriInfo) {
    MultivaluedMap<String, String> queryParameters = uriInfo.getQueryParameters();
    getArrayParameter("a", "foo", queryParameters);
}

, HttpServletRequest, getParameterMap(), .

.

public void doGet(HttpServletRequest request, HttpServletResponse response)
              throws IOException {

   System.out.println("Parameters : \n"+request.getParameterMap()+"\n End");
