method generate_url (get temporary url)

With boto library (not boto3), there is method generate_url which generates temporary url for given object. This method is availabe on connection, bucket and key objects.

import boto
con = boto.connect_s3()
tmpurl_c = con.generate_url(...)
bucket = con.get_bucket("mybucket")
tmpurl_b = bucket.generate_url(...)
key = bucket.get_object("key/name.txt")
tmpurl_k = key.generate_url(...)

I was unable to find corresponding method in boto3. Is there such a method? Or is it planned?

I am aware, that actually creating the temporary url is not a call to AWS web service (so I do not expect it to be found in AWS serices model), but for practical use it is very important.

Fortunatelly, today we may se boto to do this work, but if boto3 is supposed to be complete replacement to today boto, ability to generate temporary url seems to be important.

Faerloev,

The ClientMethod param is not clearly described, but it just means a Client method like the “get_object” (http://boto3.readthedocs.org/en/latest/reference/services/s3.html?highlight=s3 url#client). Here’s my example:

        client = boto3.client('s3')
        bucket_name = 'api_reports'

        resp = client.put_object(
                                Bucket= bucket_name, 
                                Key= filename, 
                                Body= file,
                                Expires= datetime.utcnow() + timedelta(days=7), )
        print(resp)
        url = client.generate_presigned_url(
                                            'get_object', 
                                            Params = { 
                                                      'Bucket': bucket_name, 
                                                      'Key': filename, }, 
                                            ExpiresIn = 86400, )
        print(url)

Mjello,

I’m in the same boat as @niallatbynder ; I can’t seem to figure out how generate a signed url.

CloudFront.Client.generate_presigned_url() takes a ClientMethod argument, but fails to describe what this ClientMethod can be. From my trails I get the impression, that ClientMethod should be a method on CloudFront.Client, is that correctly understood? In that case, I can’t find any methods on CloudFront.Client that fetches a file from a bucket, hence no methods to generate a signed url for.

An example of how to use this would be greatly appreciated.

Thanks in advance.
