散列在CDK / Cloudformation中资源的逻辑ID中
每当我从CDK生成cloudformation模板时，就会发现在逻辑ID中会添加某种哈希。哈希表示什么意思？例如。
Whenever I generate cloudformation template from CDK, I see that in logical ids, it adds some kind of Hash. What does that Hash mean? Eg.
Test4FCEEF4A
Test4FCEEF4A
此哈希4FCEEF4A是如何生成的？
How does this Hash 4FCEEF4A gets generated?
使用 allocateLogicalId 方法设置资源的逻辑ID，您可以在其中找到此处。它调用 makeUniqueId 方法，您可以找到此处。在 makeUniqueId 方法中，它创建逻辑ID的 hash 组件和 human 可读的逻辑ID组件。它使用 crypto 库使用 path 创建md5哈希，该哈希是从 crypt c节点的ID中获得的。 CfnElement并返回一个十六进制值。因此，您看到的哈希4FCEEF4A是在 makeUniqueId 方法中创建的哈希组件。
The logical IDs for resources are set using the allocateLogicalId method which you can find here. It calls the makeUniqueId method which you can find here. In the makeUniqueId method, it creates a hash component of the logical ID and a human-readable component of the logical ID. It uses the crypto library to create an md5 hash using path, which it gets from the IDs of the nodes of the CfnElement and returns a hex value. So the Hash 4FCEEF4A you see is the hash component that is created in the makeUniqueId method.
