截取url的参数工具类

public static Map<String,String> getParm(String url){
        String[] urlParts = url.split("\\?");
        //有参数
        String[] params = urlParts[1].split("&");
        HashMap hashMap = new HashMap<>();
        for (String param : params) {
            String[] keyValue = param.split("=");
            hashMap.put(keyValue[0], keyValue[1]);
        }
        return hashMap;
    }
