I wanted to know if someone can help me with getting the values from a query string.
This is the example: partygo://qr/?partyId=XXX&uid=XXX&name=XXX
I want to get the values from partyId, uid and name. I really dont know if there is any encoder or sth like that.
Thanks!
Solution 1:
By decoding the parameters like below,
public void getParametersFromRequest(HttpServletRequest request, HttpServletResponse response) {
String partyId = request.getParameter("partyId");
String uid= request.getParameter("uid");
String name= request.getParameter("name");
}
Solution 2:
You can achieve this using below method.
public static Map<String, String> getQueryMap(String query)
{
String[] params = query.split("&");
Map<String, String> map = new HashMap<String, String>();
for (String param : params)
{
String [] p=param.split("=");
String name = p[0];
if(p.length>1) {
String value = p[1];
map.put(name, value);
}
}
return map;
}
So then you can use:
Map params=getQueryMap(querystring);
String partyId=(String) params.get("partyId");
String uid=(String) params.get("uid");
String name=(String) params.get("name");
This is simple GET request so you can directly get the value of query string using the request object in doGet method
public void doGet(HttpServletRequest request, HttpServletResponse response) {
String partyid = request.getParameter("partyId");
//similar do others
}
