子网路由到AWSVPC似乎无法工作

为了使子网路由到AWS VPC正常工作，您需要确保AWS VPC和本地网络之间的路由设置正确。您可以在AWS VPC控制台中检查路由表设置。另外，请确保安全组设置允许从本地网络访问AWS VPC中的资源。

以下是一个Python脚本示例，可用于检查本地网络与指定VPC之间的路由设置：

import boto3

# set up connection to AWS VPC
client = boto3.client('ec2', region_name='<region>')
vpc_id = '<vpc_id>'

# retrieve VPC's routing table
route_table_id = None
response = client.describe_route_tables(Filters=[{'Name': 'vpc-id','Values': [vpc_id]}])
if response['RouteTables']:
    route_table_id = response['RouteTables'][0]['RouteTableId']

# iterate each subnet and check if routing is enabled
for subnet in client.describe_subnets(Filters=[{'Name': 'vpc-id','Values': [vpc_id]}])['Subnets']:
    subnet_id = subnet['SubnetId']
    response = client.describe_route_tables(Filters=[{'Name': 'association.subnet-id','Values': [subnet_id]}])
    if response['RouteTables']:
        routes = response['RouteTables'][0]['Routes']
        for route in routes:
            if 'DestinationCidrBlock' in route and 'InstanceId' in route:
                print('subnet', subnet_id, 'routing enabled')
