python - 使用 boto 在 s3 上上传图像

Question

这里我有一个图片 url。文件名是图片url

def upload(filename, content)
    conn = S3Connection(aws_access_key, aws_secret_key)
    b = Bucket(conn, bucket_name)
    k = Key(b)
    k.key = filename..split('/')[::-1][0]
    k.set_metadata("Content-Type", 'images/jpeg')
    k.set_contents_from_string(content)
    k.set_acl("public-read")

它上传东西到 S3 但它显示错误:

/tmp/t.jpeg could not be opened, because the associated helper application does not exist. Change the association in your preferences.

Answer 1

我很确定 images/jpeg 是错字。正确的 mimetype 是:

image/jpeg
