// 下载视频地址

    return new Promise((resolve, reject) => {
        let xhr = new XMLHttpRequest();
        xhr.open('GET', url);
        xhr.responseType = 'blob';
        xhr.onload = function(e) {
            if (e.currentTarget.status == 200) {
                var link = document.createElement('a');
                link.href = window.URL.createObjectURL(new Blob([xhr.response]));
                link.download = '视频.mp4';
                link.click();
                link.remove();
                resolve();
            }
            if(e.currentTarget.status != 200) reject();
        };
        xhr.send();
    });
