How to generate temporary URL to upload files to S3 using boto

Question

I tried uploading files using: key.generate_url(3600, method='PUT') but it says request signature does not match the signature you provided.

Please help me with this

Answer 1

Use the following code to do so:

import boto
>>> c =boto.connect_s3()
>>> fp = open('myfiletoupload.txt')
>>> content_length = len(fp.read())
>>> c.generate_url(300, 'PUT', 'test-1332789015', 'foobar', headers={'Content-Length': str(content_length)}, force_http=True)
'http://test-1332789015.s3.amazonaws.com/foobar?Signature=oUARG45mR95utXsiQYRJNiCI4x4%3D&Expires=1333731456&AWSAccessKeyId=AKIAJOTCCJRP4C3NSMYA&Content-Length=16'

Then use curl to PUT the file to that URL

$ curl --request PUT --upload-file myfiletoupload.txt "http://test-1332789015.s3.amazonaws.com/foobar?Signature=oUARG45mR95utXsiQYRJNiCI4x4%3D&Expires=1333731456&AWSAccessKeyId=AKIAJOTCCJRP4C3NSMYA&Content-Length=16"

Thank you in advance
