`from starlette.requests import Request` を使用することもできます。

**FastAPI**は、開発者の便利のためにこれを提供していますが、Starletteから直接きています。

### `response` の前後

*path operation* が `request` を受け取る前に、 `request` とともに実行されるコードを追加できます。

また `response` が生成された後、それを返す前にも追加できます。

例えば、リクエストの処理とレスポンスの生成にかかった秒数を含むカスタムヘッダー `X-Process-Time` を追加できます:

This command finds a Prometheus pod running in the specified istio system
namespace. It then executes a series of queries per requested workload to
find the following top-level workload metrics: total requests per second,
error rate, and request latency at p50, p90, and p99 percentiles. The
query results are printed to the console, organized by workload name.

Hier ist, was Sie beachten sollten und wie Sie einen Pull Request überprüfen:

### Das Problem verstehen

    // This interface doesn't declare any additional methods beyond those inherited from InvokerRequest.
    // It serves to type-specify the Options as EncryptOptions for encryption-related requests.

      if (launch == CommandLine) {
        process?.destroyForcibly()
      }
    }
  }

  private fun sendTestRequest(request: Request) {
    try {
      if (this.launch != CommandLine) {
        println(request.url)
      }

      client.newCall(request)
        .execute()
        .use {
          val firstLine =
            it.body.string()
              .lines()
              .first()

// errDiskNotFound - cannot find the underlying configured disk anymore.
var errDiskNotFound = StorageErr("drive not found")

// errDiskOngoingReq - indicates if the disk has an on-going request in progress.
var errDiskOngoingReq = StorageErr("drive still did not complete the request")

// errDriveIsRoot - cannot use the disk since its a root disk.
var errDriveIsRoot = StorageErr("drive is part of root drive, will not be used")

	ReqErr  uint64                   `json:"kms_req_error"`   // Number of requests that failed with a defined error
	ReqFail uint64                   `json:"kms_req_failure"` // Number of requests that failed with an undefined error
	Latency map[time.Duration]uint64 `json:"kms_resp_time"`   // Latency histogram of all requests
}

var defaultLatencyBuckets = []time.Duration{

A "middleware" is a function that works with every **request** before it is processed by any specific *path operation*. And also with every **response** before returning it.

* It takes each **request** that comes to your application.
* It can then do something to that **request** or run any needed code.
* Then it passes the **request** to be processed by the rest of the application (by some *path operation*).
