upload a file to S3 without creating a temporary local file in django/python












0















I am trying to save a signature in s3 database.




  • 1- so, first i get image of signature in encoded base64 format.

  • 2- then i split base64 tag from rest of the string, then decode it and save it to a variable.

  • 3- then create a file name.


  • 4-then i open that file and write the string in that.This process creates a local file in my project. then i upload that file to S3 and delete it.



    class SaveSignature(View):
    def post(self,request):
    config = GetConfig().config(request)
    tub = config['tub']
    CLOUD_FRONT_URL = config['CLOUD_FRONT_URL']

    host_ = "https://"
    user_id = request.session.get('user_id')


    image_data = request.POST.get('d')

    format, imgstr = image_data.split(';base64,')
    ext = format.split('/')[-1]
    data = base64.b64decode(imgstr)
    file_name = str(user_id)+"_signature" +"."+ ext

    user_signature = "{}/Signature/{}".format(user_id,file_name)
    sign_url = host_ + CLOUD_FRONT_URL + user_signature

    with open('static/user_signature/'+file_name, 'wb') as f:
    f.write(data)

    s3.meta.client.upload_file('static/user_signature/'+file_name,BUCKET, user_signature, ExtraArgs={'ACL':'public-read'})



though this method works but i want to upload directly without creating an extra file and writing extra code for it. But i'm not able to figure it out how to do so!

    You should be able to use an io.BytesIO instance to store that data before uploading to s3 -> boto3.amazonaws.com/v1/documentation/api/latest/reference/…
