我很确定这是我，而不是错误 - 但如果能帮助解决这个问题，我们将不胜感激

我在它的危险中撞车了

    def derive_key(self):
        """This method is called to derive the key.  If you're unhappy with
            the default key derivation choices you can override them here.
            Keep in mind that the key derivation in itsdangerous is not intended
            to be used as a security method to make a complex key out of a short
            password.  Instead you should use large random secret keys.
            """
        salt = want_bytes(self.salt)
        if self.key_derivation == 'concat':
            return self.digest_method(salt + self.secret_key).digest()
        elif self.key_derivation == 'django-concat':
            print salt
            print self.secret_key
            return self.digest_method(salt + b'signer' +
>               self.secret_key).digest()

 TypeError: cannot concatenate 'str' and 'NoneType' objects

.env/lib/python2.7/site-packages/itsdangerous.py:336: TypeError 和相关的回溯部分是：

flask_app/mgmt_admin.py:28: in login
    return jsonify(success=True, token=user.get_auth_token())
.env/lib/python2.7/site-packages/flask_security/core.py:313: in get_auth_token
    return _security.remember_token_serializer.dumps(data)
.env/lib/python2.7/site-packages/itsdangerous.py:568: in dumps
    rv = self.make_signer(salt).sign(payload)
.env/lib/python2.7/site-packages/itsdangerous.py:414: in sign
    return value + sep + self.get_signature(value)
.env/lib/python2.7/site-packages/itsdangerous.py:349: in get_signature
    key = self.derive_key()

我正在非常直接地定义应用程序：

app.config["SECRET_KEY"] = "testing_key"
app.config["TESTING"] = True

从打印值我看到：

salt: remember-salt
self.secret_key: None
