Authlib jwt token decode not working inside function












1














I am using the authlib library for decoding the JWT token .



This code is working fine when i run as it is . 



from authlib.specs.rfc7519 import jwt

encoded_jwt = '''eyJ0eXAiOiJKV1Qi.....'''

secret = b'''-----BEGIN PUBLIC KEY-----

.....

-----END PUBLIC KEY-----'''



claims = jwt.decode(encoded_jwt, secret)

print(type(claims))

import json



json_parse = json.loads(json.dumps(claims))

email = json_parse['http://wso2.org/claims/emailaddress']

print(email)

roles = json_parse['http://wso2.org/claims/role']

print(roles)

email, roles[-1]


but when I add this in to a function It's not working. through this problem I couldn't use it in the FLASK frame work. below code is not working. Please don't answer check the public key Because it's working fine in the above code. 



def getsessions():

    from authlib.specs.rfc7519 import jwt

    encoded_jwt = '''eyJ0eXAiOiJ....'''

    secret = b'''-----BEGIN PUBLIC KEY-----

    ............

    -----END PUBLIC KEY-----'''



    claims = jwt.decode(encoded_jwt, secret)

    print(type(claims))

    import json



    json_parse = json.loads(json.dumps(claims))

    email = json_parse['http://wso2.org/claims/emailaddress']

    print(email)

    roles = json_parse['http://wso2.org/claims/role']

    print(roles)

    email, roles[-1]



email,role=getsessions()



print(email)


error I get is :

          In the function, there is an indent in secret string, this will turn the PUBLIC_KEY into an invalid key, because it is not indented well. The key would be something like this in your function



          abcdadgadgadsgasdgasdg
          
    adgadgadg
          
    adgagadgadsg


          You can save your secret into a file called public_key.pem, and read the data from this file.

But the keyboard doesn't show when I tap the TextFormField at the first time. Then I try to input some letter from physical keyboard, the widget is rebuilt. Like this: login screen Nothing to be log when I run flutter run --verbose, so I logged manually. Every tapping on field, the widget called dispose -> init -> build.
