   // 创建a标签

    var publish_files = document.createElement('a');
    
    //文件的名称为时间戳加文件名后缀
    
    publish_files.download = "file.txt";
    
    publish_files.style.display = 'none';
    
    //生成一个blob二进制数据，内容为json数据
    
    var blob = new Blob($scope.publish_downloadList);
    
    //生成一个指向blob的URL地址，并赋值给a标签的href属性
    
    publish_files.href = URL.createObjectURL(blob);
    
    document.body.appendChild(publish_files);
    
    publish_files.click();
    
    document.body.removeChild(publish_files);
