Django 以html格式显示AWS BOTO上载状态

我使用Django和Angular js。我使用BOTO将照片上传到s3上。如何使用django获取上传状态并使用angular js显示

我有以下功能：

def percent_cb(complete, total):
    print '%d bytes transferred out of %d' % (complete, total)


def upload_to_s3(project_file):
    sourceDir = photos_folder + project_file +'/'
    destDir = '/photos/'+ project_file +'/'
    MAX_SIZE = 20 * 1000 * 1000
    PART_SIZE = 6 * 1000 * 1000

    conn = boto.connect_s3(AWS_ACCESS_KEY_ID, AWS_ACCESS_KEY_SECRET)
    bucket = conn.get_bucket(bucket_name)

    k = boto.s3.key.Key(bucket)
    k.key = destpat
    k.set_contents_from_filename(sourcepath, cb=percent_cb, num_cb=10)

以下是我上传示例照片时的日志：

0 bytes transferred out of 508450
57344 bytes transferred out of 508450
114688 bytes transferred out of 508450
172032 bytes transferred out of 508450
229376 bytes transferred out of 508450
286720 bytes transferred out of 508450
344064 bytes transferred out of 508450
401408 bytes transferred out of 508450
458752 bytes transferred out of 508450
508450 bytes transferred out of 508450

我想在每次打印时获得百分比_cb的输出，并将其传递给angular以用于html显示

他们有办法做到这一点吗
