    Axios({

                    if (it) {
                        ret += encodeURIComponent(it) + '=' + encodeURIComponent(data[it]) + '&';
                    }
                }

            data: data,
            withCredentials: true,
            responseType: 'blob'// 返回的数据格式，必填，不然会返回乱码
        }).then((resp) => {

            let href = window.URL.createObjectURL(new Blob([resp.data]));
