以下是一个将域映射到S3静态内容以及API网关端点的解决方案，包含代码示例。

1. 首先，您需要创建一个S3存储桶，并将您的静态内容上传到该存储桶中。确保存储桶中的文件是公开可访问的。

2. 接下来，您需要创建一个API网关，并设置一个资源和方法。在方法配置中，将集成类型设置为“AWS Service”，并选择S3作为集成服务。然后，选择您的S3存储桶作为集成端点。

3. 在API网关中创建一个自定义域名，并将其指向您的API网关端点。您可以通过配置DNS记录来实现这一点。

4. 在AWS控制台中，找到CloudFront服务，并创建一个CloudFront分发。将分发设置为使用您的API网关自定义域名作为源，并选择“自定义SSL证书”选项。

5. 等待CloudFront分发部署完成后，您将获得一个CloudFront的域名。

下面是一个使用Terraform进行AWS基础架构自动化的示例代码：

# 创建一个S3存储桶用于存储静态内容
resource "aws_s3_bucket" "static_content_bucket" {
  bucket = "my-static-content-bucket"
  acl    = "public-read"
}

# 创建API网关
resource "aws_api_gateway_rest_api" "api_gateway" {
  name = "my-api-gateway"
}

# 创建API网关资源
resource "aws_api_gateway_resource" "api_gateway_resource" {
  rest_api_id = aws_api_gateway_rest_api.api_gateway.id
  parent_id   = aws_api_gateway_rest_api.api_gateway.root_resource_id
  path_part   = "my-resource"
}

# 创建API网关方法
resource "aws_api_gateway_method" "api_gateway_method" {
  rest_api_id   = aws_api_gateway_rest_api.api_gateway.id
  resource_id   = aws_api_gateway_resource.api_gateway_resource.id
  http_method   = "GET"
  authorization = "NONE"
}

# 配置API网关集成
resource "aws_api_gateway_integration" "api_gateway_integration" {
  rest_api_id          = aws_api_gateway_rest_api.api_gateway.id
  resource_id          = aws_api_gateway_resource.api_gateway_resource.id
  http_method          = aws_api_gateway_method.api_gateway_method.http_method
  integration_http_method = "GET"
  type                 = "AWS_PROXY"
  uri                  = "arn:aws:apigateway:${var.region}:s3:path/my-static-content-bucket/*"
}

# 创建自定义域名
resource "aws_api_gateway_domain_name" "api_gateway_domain_name" {
  domain_name       = "api.example.com"
  certificate_name  = "example.com"
  regional_certificate_arn = "arn:aws:acm:us-west-2:123456789012:certificate/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
}

# 创建CloudFront分发
resource "aws_cloudfront_distribution" "cloudfront_distribution" {
  origin {
    domain_name = aws_api_gateway_domain_name.api_gateway_domain_name.cloudfront_domain_name
    origin_id   = "api-gateway-origin"
    
    custom_origin_config {
      http_port              = 80
      https_port             = 443
      origin_protocol_policy = "match-viewer"
      origin_ssl_protocols   = ["TLSv1.2"]
    }
  }

  enabled             = true
  is_ipv6_enabled     = true
  default_root_object = "index.html"
  
  default_cache_behavior {
    allowed_methods  = ["GET", "HEAD", "OPTIONS"]
    cached_methods   = ["GET", "HEAD", "OPTIONS"]
    target_origin_id = "api-gateway-origin"
    
    forwarded_values {
      query_string = false
      cookies {
        forward = "none"
      }
    }
    
    viewer_protocol_policy = "redirect-to-https"
  }
  
  viewer_certificate {
    acm_certificate_arn = "arn:aws:acm:us-west-2:123456789012:certificate/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
    ssl_support_method  = "sni-only"
  }
}
