json返回数据丢失，无法解析

url= "https://weixin.qianlima.com/yfbApp/yfbNewSub/getYfbNewSubShowDatas" post params ->openid :oFNc6s2sCiYSyfCq_V5eBgrvidck; memberType:3; lastQueryDate:2019-05-23 00:00:00

OkGo.post(Urls.WX_LOGIN) .tag(this).retryCount(3) .params("openid", "oFNc6s2sCiYSyfCq_V5eBgrvidck") .params("memberType", 3) .params("lastQueryDate", "2019-05-23 00:00:00") .execute(new StringCallback() { @Override public void onSuccess(Response response) {

                         }

                         @Override
                         public void onError(Response<String> response) {
                         }

                     }
            );

返回的json串不完整，解析不了，log里面显示的不全，json解析也是错误的，这个怎么解
