Question

我遇到错误：'NoneType'对象没有属性'get'：AttributeError。请帮我弄清楚。

lambda_handler中的文件“ /var/task/lambda_function.py”，第15行 create_stripe_customer（cardData，phone，email）

import json
import boto3
import stripe
client = boto3.client('secretsmanager')
keys = json.loads(client.get_secret_value(
  SecretId = 'arn:aws:secretsmanager:ap-so',
)['SecretString'])
public_key = keys['stripe-public']
secret_key = keys['stripe-secret']
stripe.api_key = secret_key
def lambda_handler(event, context):
    cardData = event.get('cardData')
    phone = event.get('phone')
    email = event.get('email')
    create_stripe_customer(cardData,phone,email)
    return event

def create_stripe_customer(payment_info, phone, email):
    customer_id = stripe.Customer.create( phone = phone,email=email)['id']
    payment_method_id = create_payment_method(payment_info)
    stripe.PaymentMethod.attach(payment_method_id, customer = customer_id)
    return {"customer_id": customer_id,
            "plan": create_stripe_plan(customer_id)
    }

def create_payment_method(payment_info):
    return stripe.PaymentMethod.create(type = "card",
    card = {"number": payment_info.get('cardNumber'),
            "exp_month": payment_info.get('expirationMonth'),
            "exp_year": payment_info.get('expirationYear'),
            "cvc": payment_info.get('ccv'),
            }).get('id')      
        
def create_stripe_plan(customer_id):
    return stripe.Subscription.create(
        customer = customer_id,items = [{"plan": "plan_idxxxxxxx"}]).get("id")

为什么不起作用

event.get()可能是错误的调用类型，无法在事件中检索数据。结果，该数据类型将被收集并保存为NoneType。

参考here，您可以通过调用event ['item']而不是event.get（'item'）来检索事件项。

以下是示例：

def my_handler(event, context):
    message = 'Hello {} {}!'.format(event['first_name'], 
                                    event['last_name'])  
    return { 
        'message' : message
    }

'NoneType'对象没有属性'get'：AttributeError
