save url as a file name in python

Question

I have a url such as

http://example.com/here/there/index.html

now I want to save a file and its content in a directory. I want the name of the file to be :

http://example.com/here/there/index.html

but I get error, I'm guessing that error is as the result of / in the url name.

This is what I'm doing at the moment.

        with open('~/' + response.url, 'w') as f:
            f.write(response.body)

any ideas how I should do it instead?

Answer 1

You could use the reversible base64 encoding.

>>> import base64
>>> base64.b64encode('http://example.com/here/there/index.html')
'aHR0cDovL2V4YW1wbGUuY29tL2hlcmUvdGhlcmUvaW5kZXguaHRtbA=='
>>> base64.b64decode('aHR0cDovL2V4YW1wbGUuY29tL2hlcmUvdGhlcmUvaW5kZXguaHRtbA==')
'http://example.com/here/there/index.html'

or perhaps binascii

>>> binascii.hexlify(b'http://example.com/here/there/index.html')
'687474703a2f2f6578616d706c652e636f6d2f686572652f74686572652f696e6465782e68746d6c'
>>> binascii.unhexlify('687474703a2f2f6578616d706c652e636f6d2f686572652f74686572652f696e6465782e68746d6c')
'http://example.com/here/there/index.html'
