我如何在 softlayer 的 "standalone cdn + object storage" 上缓存清除？

Question

我们正在使用 softlayer 的 "standalone cdn + object storage" 并尝试清除像

这样的 url 的缓存

HTTP URL

http:// 000aa.http.cdn.softlayer.net/00000AA/tok02/v1/AUTH_secretsecretsecretsecretsecretsecret/web/test.txt

HTTPS URL

https:// 000aa.https.cdn.softlayer.net/00000AA/tok02/v1/AUTH_secretsecretsecretsecretsecretsecret/web/test.txt

使用写在

上的方法

但是缓存清除不起作用。我如何在 softlayer 的 "standalone cdn + object storage" 上缓存清除？以下是我们的代码和错误。

方法 SoftLayer_Network_ContentDelivery_Account::purgeCache 适用于通过产品订单流程创建的 CDN 对象。正如您在文档中看到的那样，此方法需要一个 InitParameter，它是 CDN id 和要清除缓存的 URL。

错误"Object does not exist to execute method on"是因为您没有在

中指定CDN id

$client = SoftLayer\SoapClient::getClient('SoftLayer_Network_ContentDelivery_Account', [ID], $apiUsername, $apiKey);

如果您订购了 CDN，您应该可以通过页面 https://control.softlayer.com/storage/cdn or by calling the method SoftLayer_Account::getCdnAccounts. If this is your case, you can create a "origin pull mapping" by using the method SoftLayer_Network_ContentDelivery_Account::createOriginPullMapping. After that, you should be able to use purgeCache 方法看到它，使用您在 createOriginPullMapping 期间输入的 CNAME。

我无法重现您提供的第二个 PHP 代码中描述的错误。代码很好，我能够使用相同的代码制作 purgeCache，但我注意到以下内容：

以下行代码的结果为真：

$result = $objectStorage->with('/web/test.txt')->get()->purgeCache();

$result = $objectStorage->with('/web/test.txt')->purgeCache(); 

$result = $objectStorage->with('/web/test456465.txt')->purgeCache();

最后一个问题，“/web/test456465.txt”不存在但结果为真。在 purgeCache.

之前添加方法 get 时为 FALSE

错误可能与 get 方法有关，因为它说： 'NoneType'对象没有属性'get'

我建议在 purgeCache 之前添加 get 方法以验证对象是否存在，您也可以使用以下方法验证它线路代码：

$result = $objectStorage->with('/web/test.txt')->get()->getPath();
print $result;

如果打印'/web/test.txt'，则表示该对象存在。

如果错误"Failed to save ObjectStorage Object"仍然存在，您可以换个位置试试。

您也可以手动清除缓存，如下所示：

提出POST请求如下：

POST: https://000aa.https.cdn.softlayer.net/00000AA/tok02/v1/AUTH_secretsecretsecretsecretsecretsecret/web/test.txt

Headers:
X-Context: cdn
X-Auth-Token: AUTH_tka456546546546545
X-Cdn-Purge: true

其中“AUTH_tka456546546546545”是你在使用CURL时应该得到的X-Auth-Token。参见
