aws中AcmClient.describeCertificate返回值中没有ResourceRecord

我有一个需求，就是让用户自己把自己的域名绑定我们的提供的AWS服务器。

AWS需要验证证书上一篇文章中我用php的AcmClient中的requestCertificate方法申请到了证书。

复制代码

   $acmClient = new AcmClient([
            'region' => 'us-east-1',
            'version' => '2015-12-08',
            'credentials'=>[
                // 'id'=>"851725259723",
                'key'=>"AKIA4MTWICPFTJEVQ25E",
                "secret"=>"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"
            ]
            
        ]);
        

        $subdomainName = "";

        // 使用 mt_rand() 生成随机数
        $randomNumber = mt_rand(1000, 99999);
 
        $result = $acmClient->requestCertificate([
            'DomainName' =>"$domainName",  
     
            'ValidationMethod' => 'DNS',
            ''
        ]);

        $acm_certificate = $result->get("CertificateArn");

开始我以为返回的这个 arn:aws:acm:us-east-1:851725259723:certificate\/b59ed66e-edce-40da-8ed7-2f69f535ccc6 就可以配置在域名解析上。当我填上去的时候发现报错了

原来要填的不是这个。

后来我在AWS的后台证书上发现，原来证书里有一个domain。通常我们如果是自己来绑定域名，到后台来复制过去，然后去到域名服务商那里填写信息解析域名就可以了。

但是我们的需求是，通过Api获取到CNAME等信息，通过接口返回给用户，让用户自己去绑定域名。

第一步通过Api接口 requestCertificate方法申请证书是成功了，但是requestCertificate的返回里没有我们要的CNAME信息。

通过查看文档，发现describeCertificate方法返回了我要的东西。ResourceRecord里面包含的就是。https://docs.aws.amazon.com/zh_cn/acm/latest/APIReference/API_DescribeCertificate.html

于是我写好了调用方法：

复制代码

       // echo $acm_certificate;
            $certificate_detail = $acmClient->describeCertificate(
                [
                    "CertificateArn"=> $acm_certificate
                ],
            );

返回值是这样的：

Model Data
----------
Data can be retrieved from the model object using the get() method of the
model (e.g., `$result->get($key)`) or "accessing the result like an
associative array (e.g. `$result['key']`). You can also execute JMESPath
expressions on the result data using the search() method.

{
    "Certificate": {
        "CertificateArn": "arn:aws:acm:us-east-1:851725259723:certificate\/b59ed66e-edce-40da-8ed7-2f69f535ccc6",

                "ValidationStatus": "PENDING_VALIDATION",

    },

        "effectiveUri": "https:\/\/acm.us-east-1.amazonaws.com",

        },
        "transferStats": {
            "http": [
                []
            ]
        }
    }
}

文档上明明说会返回这个值，但我实际结果里面没有。怎么办？我到处搜索，找客服还要花钱。没办法，继续折腾。偶然一次，发现去掉"IdempotencyToken"，这个动态随机参数时，我重复点击请求我写的接口（里面包含有requestCertificate和describeCertificate这两个操作），突然有一次返回的结果里面有ResourceRecord。

到此我恍然大悟，原来是ResourceRecord要返回的时候还没拿到，需要多次请求。直接返回值里有ResourceRecord为止。
