以下是一个使用AWS CDK创建多个行为和源的代码示例:
import * as cdk from 'aws-cdk-lib';
import { aws_cloudfront as cloudfront } from 'aws-cdk-lib';
export class CloudFrontStack extends cdk.Stack {
constructor(scope: cdk.Construct, id: string, props?: cdk.StackProps) {
super(scope, id, props);
// 创建一个S3源
const s3Origin = new cloudfront.OriginAccessIdentity(this, 'S3Origin', {
comment: 'CDK S3 Origin',
});
// 创建一个S3分布
const s3Distribution = new cloudfront.CloudFrontWebDistribution(this, 'S3Distribution', {
originConfigs: [
{
s3OriginSource: {
s3BucketSource: s3Bucket,
originAccessIdentity: s3Origin,
},
behaviors: [
{
isDefaultBehavior: true,
compress: true,
allowedMethods: cloudfront.CloudFrontAllowedMethods.ALL,
cachedMethods: cloudfront.CloudFrontAllowedCachedMethods.GET_HEAD_OPTIONS,
forwardedValues: {
queryString: false,
cookies: {
forward: 'none',
},
},
},
],
},
],
});
// 创建一个API Gateway源
const apiGatewayOrigin = new cloudfront.CustomOriginConfig({
domainName: 'api.example.com',
});
// 创建一个API Gateway分布
const apiGatewayDistribution = new cloudfront.CloudFrontWebDistribution(this, 'ApiGatewayDistribution', {
originConfigs: [
{
customOriginSource: apiGatewayOrigin,
behaviors: [
{
pathPattern: '/api/*',
allowedMethods: cloudfront.CloudFrontAllowedMethods.ALL,
forwardedValues: {
queryString: true,
cookies: {
forward: 'all',
},
},
},
],
},
],
});
// 输出分布的域名
new cdk.CfnOutput(this, 'S3DistributionDomainName', {
value: s3Distribution.distributionDomainName,
});
new cdk.CfnOutput(this, 'ApiGatewayDistributionDomainName', {
value: apiGatewayDistribution.distributionDomainName,
});
}
}
这个例子创建了两个分布,一个使用S3作为源,另一个使用API Gateway作为源。每个分布都有自己的行为和缓存设置。最后,分布的域名被输出到CDK堆栈。
请注意,上面的代码是使用AWS CDK的TypeScript库编写的。如果您使用其他编程语言,可以根据您选择的语言和CDK库进行相应的调整。
