### Dependency injection

FastAPI'ın inanılmaz derecede kullanımı kolay, fakat inanılmaz derecede güçlü <abbr title='"components", "resources", "services", "providers" olarak da bilinen'><strong>Dependency Injection </strong></abbr> sistemi var.

* Dependencylerin bile dependencies'i olabiliyor, FastAPI bunun  için **graph of "dependency"** yaratıyor.

### Wstrzykiwanie Zależności

FastAPI zawiera niezwykle łatwy w użyciu, ale niezwykle potężny system <abbr title='Po angielsku: Dependency Injection. Znane również jako "components", "resources", "services", "providers"'><strong>Wstrzykiwania Zależności</strong></abbr>.

* Nawet zależności mogą mieć zależności, tworząc hierarchię lub **"graf" zależności**.
* Wszystko jest **obsługiwane automatycznie** przez framework.

### Dependency Injection { #dependency-injection }

FastAPI includes an extremely easy to use, but extremely powerful <abbr title='also known as "components", "resources", "services", "providers"'><strong>Dependency Injection</strong></abbr> system.

* Even dependencies can have dependencies, creating a hierarchy or **"graph" of dependencies**.
* All **automatically handled** by the framework.

// Every 10 seconds a space character is sent.
// keepHTTPReqResponseAlive will wait for the returned body to be read before starting the ticker.
// The returned function should always be called to release resources.
// An optional error can be sent which will be picked as text only error,
// without its original type by the receiver.
// waitForHTTPResponse should be used to the receiving side.

...path-nya adalah:

```
/items/foo
```

/// info

"path" juga biasa disebut "endpoint" atau "route".

///

ketika membuat API, "path" adalah jalan utama untuk memisahkan "concern" dan "resources".

#### Operasi

"Operasi" di sini merujuk ke salah satu dari metode HTTP berikut.

Salah satu dari:

* `POST`
* `GET`
* `PUT`
* `DELETE`

...dan operasi lainnya yang unik:

- Empty values are no longer assigned to undefined resources (CPU or memory) when storing the resources allocated to the pod in checkpoint. ([#117615](https://github.com/kubernetes/kubernetes/pull/117615), [@aheng-ch](https://github.com/aheng-ch))

### Dependency Injection

FastAPI bao gồm một hệ thống <abbr title='cũng biết đến như là "components", "resources", "services", "providers"'><strong>Dependency Injection</strong></abbr> vô cùng dễ sử dụng nhưng vô cùng mạnh mẽ.

            stopProactiveHealthChecking();
        }
        log.info("Proactive health checking {}", enabled ? "enabled" : "disabled");
    }

    /**
     * Close the transport pool and cleanup resources
     */
    public void closePool() {
        stopProactiveHealthChecking();
        healthCheckExecutor.shutdown();
        try {
            if (!healthCheckExecutor.awaitTermination(5, TimeUnit.SECONDS)) {

  - Support allocatable resources overrides via VMSS tags
  - Add missing stable labels in template nodes
  - Proactively set instance status to deleting on node deletions
  
  ### Cluster API
  - Migrate interaction with the API from using internal types to using Unstructured
  - Improve tests to work better with constrained resources
  - Add support for node auto-discovery

TF_CAPI_EXPORT extern void TF_FinishWhile(const TF_WhileParams* params,
                                          TF_Status* status,
                                          TF_Output* outputs);

// Frees `params`s resources without building a while loop. `params` is no
// longer valid after this returns. Either this or TF_FinishWhile() must be
// called after a successful TF_NewWhile() call.
