获取URL中的参数

// mLinkKey:  mLink  的 key, mLink的唯一标识

                    MLink.getInstance(context).register("jiduokey", new MLinkCallback() {
                        public void execute(Map paramMap, Uri uri, Context context) {
                                
                            JSONObject jsonObj = new JSONObject(paramMap);
                            openUrlParm = null;
                            if (jsonObj.length() > 0) {
                                openUrlParm = jsonObj.toString();

                            }
                            Log.d("MLink url：", "openUrlParm ：" + openUrlParm);
                            Log.d("MLink url：", "openUrlParm ");
                                                      //此句获取url里对应字段的数据
                             roomids = uri.getQueryParameter("code");
    
                    }
                    });
