Callback Function Not running

[yingi keme]

I have a callback function(webhook) implemented below

def call_back(request, param):

    # Testnet

    method='GET'

    x_signature = request.headers.get('X-Signature')

    print(siri)

        

    request_uri_encoded = str(request).splitlines()[0].split()[1]

    request_uri = urllib.parse.unquote(request_uri_encoded)

        

    constant_digest = hashlib.sha512('').digest() # [207, 131, 225, 53, 126,.........., 249, 39, 218, 62]

        

    requestt = method+request_uri+constant_digest

    raw_signature = hmac.new(secret, requestt, hashlib.sha512)

    b64_signature = base64.b64encode(raw_signature.digest())

        

    print('request_uri_encoded: ', request_uri_encoded)

    print('request_uri: ', request_uri) 

    print('x_signature: ', x_signature) 

    print('b64_signature: ', b64_signature) 

        

    if (x_signature == b64_signature):  # IT PRINTS ERROR

        print('SUCCESS')

    else:

        print('ERROR') 

But this callback function dont get to run. The API is to issue a  GET http request to the url specified as my callback url.

The url specified is 'https://Jshhhtoo.localtunnel.me/callback/blue-cap'

And in my urls.py i have this pattern

url(r'^callback/(?P<param>[-\w]+)/$', call_back, name='callback'),

But i dont seem to get why the callback function refuses to run even though from my command line i see that the webservice

keeps issuing a GET callback request. Here is what the GET request shows in my command

[11/Nov/2017 03:23:17] "GET /callback/blue-cap?order_id=204199&amount=4570384&amount_in_btc=

0.04570384&amount_paid_in_btc=0.04570384&status=2&address=muAYN5HZBN4VfvmVhZhTnm7yBN33JQ3JGD&tid=9a5327bb9efa3b2be285c8a47222d6c89a95fd2d3e10c7c4707974c0c52e7e57&

transaction_ids=[%229a5327bb9efa3b2be285c8a47222d6c89a95fd2d3e10c7c4707974c0c52e7e57%22]&keychain_id=2&last_keychain_id=1&after_payment_redirect_to=

https%3A%2F%2Fbitcoinkem.localtunnel.me%2Fsucessful&auto_redirect=true HTTP/1.1" 301 0

Any help please !!!!

Do you have a url entry above that is also matching it?

No i dont.

But i am thinking that since it is a GET http request, Then there shouldnt be a parameter in the url pattern. So maybe it should be

url(r'callback/' call_back) instead the previous one i did.

Although i havent tried it out yet.

Your regex is looking for a trailing slash. Try this URL or fix your regex:

https://Jshhhtoo.localtunnel.me/callback/blue-cap/
