事实上，所有（或大多数）Web 框架的工作方式都是这样的。

你从不会直接调用这些函数。它们由你的框架（此处为 **FastAPI**）调用。

通过依赖注入系统，你还可以告诉 **FastAPI**，你的*路径操作函数*还“依赖”某些应在*路径操作函数*之前执行的内容，**FastAPI** 会负责执行它并“注入”结果。

“依赖注入”的其他常见术语包括：

* 资源（resources）
* 提供方（providers）
* 服务（services）
* 可注入（injectables）
* 组件（components）

## **FastAPI** 插件 { #fastapi-plug-ins }

可以使用**依赖注入**系统构建集成和“插件”。但实际上，根本**不需要创建“插件”**，因为通过依赖项可以声明无限多的集成与交互，使其可用于*路径操作函数*。

* The AWS credential provider can now obtain ECR credentials even without the AWS cloud provider or being on an EC2 instance. Additionally, AWS credential provider caching has been improved to honor the ECR credential timeout.

* Fix space issue in volumePath with vSphere Cloud Provider ([#38338](https://github.com/kubernetes/kubernetes/pull/38338), [@BaluDontu](https://github.com/BaluDontu))
* Fix issue when attempting to unmount a wrong vSphere volume ([#37413](https://github.com/kubernetes/kubernetes/pull/37413), [@BaluDontu](https://github.com/BaluDontu))

- Kubelet, when using cloud provider external, initializes temporary the node addresses using the --node-ip flag values if set, until the cloud provider overrides it. ([#121028](https://github.com/kubernetes/kubernetes/pull/121028), [@aojea](https://github.com/aojea)) [SIG Cloud Provider and Node]

- The in-tree cloud provider for AWS (and the EBS storage plugin) has now been removed. Please use the external cloud provider and CSI driver from https://github.com/kubernetes/cloud-provider-aws instead.

/**
 * A type implemented by, or extended by maven itself.
 * Maven provides implementations of those types and may inject them in plugins.
 * <p>
 * A type can be marked {@link Consumer} or {@link Provider} but not both. A type is assumed to be
 * {@link Consumer} if it is not marked either {@link Consumer} or {@link Provider}.
 * <p>
 * A package can be marked {@link Provider}. In this case, all types in the package are considered

- Removed the last remaining in-tree gcp cloud provider and credential provider.
  Please use the external cloud provider and credential provider from https://github.com/kubernetes/cloud-provider-gcp
  instead. ([#124519](https://github.com/kubernetes/kubernetes/pull/124519), [@dims](https://github.com/dims)) [SIG API Machinery, Apps, Auth, Autoscaling, Cloud Provider, Instrumentation, Network, Node, Scheduling, Storage and Testing]

- Kubelet: The `--azure-container-registry-config` flag has been deprecated and will be removed in a future release, please use `--image-credential-provider-config` and `--image-credential-provider-bin-dir` to setup acr credential provider instead.
