doPost正在返回游戏时间超过5分钟的游戏，即使我在HTML表单中输入最多5分钟作为参数也是如此。为什么？我没有线索。我已打印出Boolean表达式中使用的所有参数，以查看它们是否包含正确的值，并且它们似乎是这样做的。这是印刷品的例子：
信息：拥有：false minPlayers：3 selectedPlayers：1 maxPlayers：6 selectedPlaytime：5 gameTime：90信息：拥有：true minPlayers：2 selectedPlayers：1 maxPlayers：-1 chosenPlaytime：5 gameTime：-1 Info：
拥有：false minPlayers：2 selectedPlayers：1 maxPlayers：6 selectedPlaytime：5 gameTime：90信息：拥有：false minPlayers：1 selectedPlayers：1 maxPlayers：1 selectedPlaytime：5 gameTime：50 Info：
拥有：false minPlayers：-1 selectedPlayers：1 maxPlayers：-1 selectedPlaytime：5 gameTime：-1信息：拥有：true minPlayers：2 selectedPlayers：1 maxPlayers：7 selectedPlaytime：5 gameTime：30
这是我的代码：
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
//processRequest(request, response);
String players = request.getParameter("players");
String playtime = request.getParameter("playtime");
int chosenPlayers = Integer.parseInt(players);
int chosenPlaytime = Integer.parseInt(playtime);
URL url = new URL("http://bgg-json.azurewebsites.net/collection/Dan%20Xxxxxxx"); //hidden by me now
URLConnection yc = url.openConnection();
try (BufferedReader in = new BufferedReader(new InputStreamReader(yc.getInputStream()))) {
String inputLine = null;
String result = "{\"boardgames\":";
while ((inputLine = in.readLine()) != null) {
result = result + inputLine;
}
result = result + ", \"responseStatus\": 200}";
JSONTokener tokener = new JSONTokener(result);
JSONObject joRoot = (JSONObject) tokener.nextValue();
JSONArray jarr = joRoot.getJSONArray("boardgames");
int numberOfBoardgames = jarr.length();
response.setContentType("text/html;charset=UTF-8");
