使用Boto上传目录时设置Content-Type键

Question

I am using os.walk to get a directory of files and then using the boto suggested way of uploading large files. From what I have read, I need to set the content-type key at upload time, but the directory has multiple file types that need different content-type keys. Any suggestions on how to get the proper content-type for each file so it can be set in the key? Mime types library? Something else?

Answer 1

From the documentation :

When you send data to S3 from a file or filename, boto will attempt to determine the correct mime type for that file and send it as a Content-Type header. The boto package uses the standard mimetypes package in Python to do the mime type guessing.

From the source :

self.content_type = mimetypes.guess_type(self.path)[0]
