在 AWS Lambda 上的 python 中使用枕头 package 保存图像时出现错误/错误的内容类型

Question

I'm trying to generate dimensional images using a pillow package using python. The problem I'm facing is 'Content-Type gets converting automatically to binary/octet-stream but my original image Content-Type is image/jpeg '

Here is code which I'm using to generate thumbnails

 def resize_image(image_path, resized_path, thumbnail_size):
    with Image.open(image_path) as image:
        image.thumbnail((thumbnail_size["x"], thumbnail_size["y"]))
        image.save(resized_path,"JPEG",progressive=True)

Answer 1

Finally found the solution, problem is while uploading the file to s3 you need to specify the content-type explictly.

s3_client.upload_file(upload_path, '{}'.format(bucket),
                      f'{filename}',ExtraArgs={'ContentType': '{}'.format(mimeType),'Metadata':{}})
