将自定义域名迁移至 API Gateway 中的其他 API 端点

使用以下 update-domain-name 命令将边缘优化的自定义域名迁移到区域自定义域名：

aws apigateway update-domain-name \
    --domain-name 'api.example.com' \
    --patch-operations  '[ 
        { "op":"add", "path": "/endpointConfiguration/types","value": "REGIONAL" },
        { "op":"add", "path": "/regionalCertificateArn", "value": "arn:aws:acm:us-west-2:123456789012:certificate/cd833b28-58d2-407e-83e9-dce3fd852149" }
      ]'

区域证书必须与区域 API 位于相同区域。

输出将与以下内容类似：

{
    "certificateArn": "arn:aws:acm:us-east-1:123456789012:certificate/34a95aa1-77fa-427c-aa07-3a88bd9f3c0a",
    "certificateName": "edge-cert",
    "certificateUploadDate": "2017-10-16T23:22:57Z",
    "distributionDomainName": "d1frvgze7vy1bf.cloudfront.net",
    "domainName": "api.example.com",
    "endpointConfiguration": {
        "types": [
            "EDGE",
            "REGIONAL"
        ]
    },
    "regionalCertificateArn": "arn:aws:acm:us-west-2:123456789012:certificate/cd833b28-58d2-407e-83e9-dce3fd852149",
    "regionalDomainName": "d-fdisjghyn6.execute-api.us-west-2.amazonaws.com"
}

对于迁移后的区域自定义域名，生成的 regionalDomainName 属性返回区域 API 主机名。您必须设置 DNS 记录以将区域自定义域名指向此区域主机名。这使绑定到自定义域名的流量可以路由到区域主机。

设置 DNS 记录后，您可以删除边缘优化的自定义域名。使用以下 update-domain-name 命令删除边缘优化的自定义域名：

aws apigateway update-domain-name \
    --domain-name api.example.com \
    --patch-operations '[
            {"op":"remove", "path":"/endpointConfiguration/types", "value":"EDGE"},
            {"op":"remove", "path":"certificateName"},
            {"op":"remove", "path":"certificateArn"}
        ]'

使用以下 update-domain-name 命令将区域自定义域名迁移到边缘优化的自定义域名：

aws apigateway update-domain-name \
    --domain-name 'api.example.com' \
    --patch-operations  '[ 
        { "op":"add", "path": "/endpointConfiguration/types","value": "EDGE" },
        { "op":"add", "path": "/certificateName", "value": "edge-cert" },
	{"op":"add", "path": "/certificateArn", "value": "arn:aws:acm:us-east-1:738575810317:certificate/34a95aa1-77fa-427c-aa07-3a88bd9f3c0a"}
      ]'

边缘优化的域证书必须在 us-east-1 区域中创建。

输出将与以下内容类似：

{
    "certificateArn": "arn:aws:acm:us-east-1:738575810317:certificate/34a95aa1-77fa-427c-aa07-3a88bd9f3c0a",
    "certificateName": "edge-cert",
    "certificateUploadDate": "2017-10-16T23:22:57Z",
    "distributionDomainName": "d1frvgze7vy1bf.cloudfront.net",
    "domainName": "api.example.com",
    "endpointConfiguration": {
        "types": [
            "EDGE",
            "REGIONAL"
        ]
    },
    "regionalCertificateArn": "arn:aws:acm:us-east-1:123456789012:certificate/3d881b54-851a-478a-a887-f6502760461d",
    "regionalDomainName": "d-cgkq2qwgzf.execute-api.us-east-1.amazonaws.com"
}

对于指定的自定义域名，API Gateway 将返回边缘优化的 API 主机名作为 distributionDomainName 属性值。您必须设置 DNS 记录以将边缘优化自定义域名指向此分配域名。这使绑定到边缘优化的自定义域名的流量可以路由到边缘优化的 API 主机名。

设置 DNS 记录之后，您可以删除自定义域名的 REGION 端点类型：使用以下 update-domain-name 命令删除区域端点类型：

aws apigateway update-domain-name \
    --domain-name api.example.com \
    --patch-operations '[
        {"op":"remove", "path":"/endpointConfiguration/types", value:"REGIONAL"},
        {"op":"remove", "path":"regionalCertificateArn"}
      ]'

输出内容如下所示：

{
    "certificateArn": "arn:aws:acm:us-east-1:738575810317:certificate/34a95aa1-77fa-427c-aa07-3a88bd9f3c0a",
    "certificateName": "edge-cert",
    "certificateUploadDate": "2017-10-16T23:22:57Z",
    "distributionDomainName": "d1frvgze7vy1bf.cloudfront.net",
    "domainName": "api.example.com",
    "endpointConfiguration": {
        "types": "EDGE"
    }
}
