调用接口问题，急。。。。

Auth auth = new Sign(APP_ID,APP_SECRET);
                        YZClient client = new DefaultYZClient(auth); //new Sign(appKey, appSecret)
                        YouzanItemGetParams youzanItemGetParams = new YouzanItemGetParams();
                        youzanItemGetParams.setItemId(345122270l);
                        YouzanItemGet youzanItemGet = new YouzanItemGet();
                        youzanItemGet.setAPIParams(youzanItemGetParams);
                        YouzanItemGetResult skus_result = client.invoke(youzanItemGet);
java.lang.RuntimeException: com.fasterxml.jackson.databind.JsonMappingException: Unexpected token (VALUE_NUMBER_INT), expected END_ARRAY: Attempted to unwrap single value array for single 'String' value but there was more than a single value in the array

应该token这里处理有问题，参考下demo:
YZClient client = new DefaultYZClient(new Token("token")); //new Sign(appKey, appSecret)
