Amazon Web Services (AWS) S3 is a popular storage service that allows users to store and retrieve data from the cloud. Boto3 is a Python library that allows developers to connect to AWS S3 using Python code. In this blog, we will explore how to use Boto3 configuration to master AWS S3 content types, and we will compare two approaches: using Boto3 without configuration and using Boto3 with configuration.

What are Content Types in AWS S3?

Content types are metadata that describe the data being stored in AWS S3. They are an important aspect of S3 because they allow S3 to understand what type of data is being stored, which is useful for many different purposes. For example, if you are storing images in S3, you would want to specify the image/jpeg or image/png content type so that the browser knows how to display the image.

Using Boto3 without Configuration

The simplest way to interact with AWS S3 using Boto3 is to create an S3 client and use the client methods to perform operations on S3 objects. However, when uploading files to S3, Boto3 may not always set the correct content type by default. When this happens, the uploaded file may not be displayed correctly in the browser. To avoid this, you can manually set the content type for each object using the put_object method.

Example Code

“`import boto3s3 = boto3.client(‘s3’)with open(‘/path/to/file’, ‘rb’) as f: s3.upload_fileobj(f, ‘bucket_name’, ‘key_name’, ExtraArgs={‘ContentType’: ‘image/jpeg’})“`

Using Boto3 with Configuration

A better way to interact with AWS S3 using Boto3 is to create an S3 resource and use the resource methods to perform operations on S3 objects. This method allows you to set default configurations for all objects uploaded to S3, including the content type. You can set the default content type by configuring the S3 bucket policy or by setting the default content type in the S3 resource.

Example Code

“`import boto3s3 = boto3.resource(‘s3’)# Configure the bucket policybucket = s3.Bucket(‘bucket_name’)policy = bucket.Policy()policy.put(Policy='{Version: 2012-10-17, Statement: [{Sid: PublicReadGetObject,Effect: Allow,Principal: *,Action: [s3:GetObject],Resource: [arn:aws:s3:::bucket_name/*],Condition: {IpAddress: {aws:SourceIp: [, yy.yy.yy.yy/yy]}}},{Sid: DenyAllExceptAdmin,Effect: Deny,Principal: *,Action: [s3:*],Resource: [arn:aws:s3:::bucket_name/*],Condition: {Bool: {aws:SecureTransport: false}}}]}’)# Set the default content typedef set_metadata(object_summary): object_summary.metadata.update({‘Content-Type’: ‘text/html’})s3.meta.client.upload_file(‘/path/to/file’, ‘bucket_name’, ‘key_name’, Callback=ProgressPercentage(‘/path/to/file’), ExtraArgs={‘Metadata’: {‘Color’: ‘red’}, ‘ACL’: ‘public-read’, ‘ContentType’:’image/jpeg’}, Config=boto3.s3.transfer.TransferConfig(multipart_threshold=1024*25, max_concurrency=10,callback=set_metadata))“`

Comparison Table

Boto3 without Configuration Boto3 with Configuration
Pros – Simple and easy to use
– No need to set up default configurations
– More control over default settings
– Easy to configure and customize
Cons – Must manually set content type for each object
– Risk of displaying incorrect file format or corrupted file in browser
– More complex configuration settings
– Must be set up beforehand


In conclusion, both methods of using Boto3 to interact with AWS S3 have their advantages and disadvantages. Using Boto3 without configuration is easier to use but requires more manual work in setting content types for individual objects. On the other hand, using Boto3 with configuration may require more setup time but allows greater control over default settings. Ultimately, the choice depends on the user’s specific needs and level of control required for their S3 resources.
