AWSAPIGateway的自定义域名出现404错误：未找到。
- 检查API Gateway的部署是否与自定义域名匹配，包括协议、域名和路径。 示例代码：
apiVersion: apigatewayv2/v2 kind: Api metadata: name: my-api spec: protocolType: HTTP routeSelectionExpression: $request.path target: virtualService: virtualServiceName: my-api.aws.example.com 2. 确保自定义域名已经映射到正确的API网关。可使用AWS Route 53进行DNS解析。 示例代码：
{ "AWSTemplateFormatVersion": "2010-09-09", "Resources": { "DomainName": { "Type": "AWS::ApiGatewayV2::DomainName", "Properties": { "DomainName": "my-api.aws.example.com", "DomainNameConfigurations": [ { "CertificateArn": "arn:aws:acm:us-west-1:123456789012:certificate/12345678-1234-1234-1234-123456789012", "EndpointType": "REGIONAL" } ] } } } } 3. 检查API的集成是否正确。如果使用Lambda函数作为后端，则需确保Lambda函数已经部署并与API Gateway正确配置，以便能够进行集成。 示例代码：
apiVersion: apigatewayv2/v2 kind: Integration metadata: name: my-api-lambda-integration spec: apiName: my-api credentials: name: my-lambda-permission integrationType: AWS_PROXY integrationUri: arn:aws:apigateway:us-west-2:lambda:path/2015-03-31/functions/arn:aws:lambda:us-west-2:123456789012:function:my-lambda/invocations passthroughBehavior: WHEN_NO_TEMPLATES payloadFormatVersion: 2.0
