使用 meta = image/jpeg - python/boto3 将图像上传到 s3 [英] Uploading images to s3 with meta = image/jpeg - python/boto3

问题描述

如何将使用 boto3 上传到 AWS S3 的图像的 ContentType 设置为 content-type:image/jpeg?

How do I go about setting ContentType on images that I upload to AWS S3 using boto3 to content-type:image/jpeg?

目前，我使用以下命令使用 buto3/python 2.7 将图像上传到 S3:

Currently, I upload images to S3 using buto3/python 2.7 using the following command:

s3.upload_fileobj(bytes_io_file, bucket_name, filename)

但是，要将上传对象的类型设置为 ContentType='image/jpeg'，我必须通过 Web 界面手动选择 S3 上的所有文件夹"，并将元数据设置为 Content-type : Image/jpeg

However, to set the uploaded object's type to ContentType= 'image/jpeg', I have to manually select all 'folders' on S3 through the web interface, and set metadata to Content-type : Image/jpeg

有没有办法在我上面的上传请求中设置这个标志?

Is there a way to set this flag in the upload request i have above?

先谢谢你！

推荐答案

将其添加到 ExtraArgs 参数中:

Add it in the ExtraArgs argument:

s3.upload_fileobj(bytes_io_file, bucket_name, filename, ExtraArgs={ "ContentType": "image/jpeg"})
