How to test if a URL contains certain parameters but not others using regex

I have an url in this format:


I need a regex to match the path and params1 and params2 in any order but if param3 is present then I need it to fail so:

String str1 = "/path?param1=value1&param2=value2"; // This will match
String str2 = "/path?param2=value2&param1=value1"; // This will match
String str3 = "/path?param1=value1&param2=value&param3=value3"; // This will not match

So for I've tried using lookarounds to match the parameters but it is failing:
