This is useful when transmitting data to networks or applications that cannot process raw binary data but would readily handle text. The Base64 encoding is used to convert bytes that have binary or text data into ASCII characters. Now that we know how to Bas64 encode binary data in Python, let's move on Base64 decoding binary data. Using AWS Lambda to save files to AWS S3 using Node.js use the botoS3 method set_contents_from_string, Method 2: That's what I'd need to put into a webpage if for example I want to display the image like this. :param base_64_str: base 64 string of the image to push to S3. The answer for my question is use boto set_meta_data and set the content type to 'image/jpeg'. So, for example, the image in the HTML might look like this: Understanding that data sometimes need to be sent as text so it won't be corrupted, let's look at how we can use Python to Base64 encoded and decode data. Encoding and Decoding Base64 Strings in Python - Stack Abuse We continue by calling the base64.b64decode method to decode the base64_bytes into our message_bytes variable. convert the base64 to StringIO and use set_contents_from_file. from botocore.vendored import requests import base64 import boto3 s3 = boto3.resource('s3') bucket_name = 'bukcetname' #where the file will be uploaded, if you want to upload the file to folder use 'folder name/filename.jpeg' file_name_with_extention = 'filename.jpeg' url_to_download = 'url' #make sure there is no data:image/jpeg;base64 in the First, the strings are converted into byte-like objects and then encoded using the base64 module. I am trying to upload a base 64 string , which is basically image data to an S3 bucket using Python. Pipedream's integration platform allows you to integrate Uploadcare and Helper Functions remarkably fast. We then encode our message into a bytes-like object with encode('ASCII').
