Amazon web services cdk api网关路由53 lambda自定义域名不工作

有人提出过类似的问题，但没有一个能帮助我解决我面临的问题。 我试图做的是将我的api gateway/lamnda函数与自定义域名连接起来，由于某种原因，调用api/domain时没有返回我所期望的结果

cdk版本：1.53.0

    const lambdaFunction = new lambda.Function(this, 'LambdaApi', {
      functionName: 'lambda-api',
      handler: 'lambda.handler',
      runtime: lambda.Runtime.NODEJS_12_X,
      code: new lambda.AssetCode(join(process.cwd(), '../api/dist')),
      memorySize: 128,
      timeout: cdk.Duration.seconds(5),
    })

    const zone = route53.HostedZone.fromLookup(scope, 'Zone', {
     'example.com',
     privateZone: false,
    })

    const certificate = certificatemanager.Certificate.fromCertificateArn(
     this,
     'Certificate',
     CERT_ARN,
    )

    const api = new apigateway.LambdaRestApi(this, 'LambdaApiGateway', {
      handler: lambdaFunction,
      proxy: true,
      endpointTypes: [apigateway.EndpointType.EDGE],
      defaultCorsPreflightOptions: {
        allowOrigins: apigateway.Cors.ALL_ORIGINS,
      },
      options: {
        restApiName: 'gateway-api',
        domainName: {
          domainName: 'api.example.com',
          certificate,
        },
        deployOptions: {
          stageName: 'prod',
          metricsEnabled: true,
          loggingLevel: apigateway.MethodLoggingLevel.INFO,
          dataTraceEnabled: true,
        },
      },
    })

    new route53.ARecord(this, 'CustomDomainAliasRecord', {
      zone,
      recordName: 'api',
      target: route53.RecordTarget.fromAlias(new targets.ApiGateway(api)),
    })

部署过程工作正常，在路由器53上创建了一条指向api网关域名的记录，并按照

stageName

中的指定创建了指向

prod

的api映射，但在调用域名时它不起作用，但在调用api网关端点时它起作用

api.example.com/ping

返回

health

{id}.execute api.us-east-1.amazonaws.com/prod/ping

返回当前日期

我一直在研究，但我无法找出为什么

api.example.com/ping

不起作用

我们已经完成了您在那里所做的大部分工作，但是在创建区域和证书之后，我们得到了如下结果：

const customDomain = new DomainName(this, 'customDomain', {
    domainName: 'api.example.com',
    certificate: certificate,
    endpointType: EndpointType.REGIONAL // yours may be Edge here
})

我们还使用basePathMapping，因此不必在域的末尾使用“dev | stg | prod”

new BasePathMapping(this, 'CustomBasePathMapping', {
    domainName: customDomain,
    restApi: api // again yours may differ here
})

在大多数情况下，我们已经完成了您在那里所做的工作，但是在区域和证书创建之后，我们得到了如下内容：

const customDomain = new DomainName(this, 'customDomain', {
    domainName: 'api.example.com',
    certificate: certificate,
    endpointType: EndpointType.REGIONAL // yours may be Edge here
})

我们还使用basePathMapping，因此不必在域的末尾使用“dev | stg | prod”

new BasePathMapping(this, 'CustomBasePathMapping', {
    domainName: customDomain,
    restApi: api // again yours may differ here
})

我修复了cloudfront发行版，下面是代码

  this,

    },
    options: {
      restApiName: 'gateway-api',

  },
)

    ),
  },
)
