第二种方法

/**将属性中含有null的，，全部置为''空字符串 */
                for (var key in this.mydata) {
                    /*key表示每一个健*/
                    if (this.mydata[key] === null) {
                        this.mydata[key] = "";
                    }
                }
                let json = JSON.parse(JSON.stringify(this.mydata));
                json.fromCreateTime = json.fromCreateTime ? this.dateStrToTimestamp(json.fromCreateTime + ' 00:00:00') : ''
                json.toCreateTime = json.toCreateTime ? this.dateStrToTimestamp(json.toCreateTime + ' 23:59:59') : ''
                let url = Network.API["API_HOTEL"]["REPORT_PAY_EXCEL"] + "?" + this.JsonToUrlParams(json);
                window.open(url, "_blank");
