Bu alt uygulama da standart bir FastAPI uygulamasıdır; ancak "mount" edilecek olan budur:

{* ../../docs_src/sub_applications/tutorial001_py310.py hl[11, 14:16] *}

### Alt uygulamayı mount edin { #mount-the-sub-application }

Üst seviye uygulamanızda (`app`), alt uygulama `subapi`’yi mount edin.

Bu örnekte `/subapi` path’ine mount edilecektir:

{* ../../docs_src/sub_applications/tutorial001_py310.py hl[11, 19] *}

	MOVWU	(R5)(R4.UXTW<<3), R10                            // ERROR "invalid index shift amount"
	MOVWU	(R5)(R4<<1), R10                                 // ERROR "invalid index shift amount"
	MOVB	(R5)(R4.SXTW<<5), R10                            // ERROR "invalid index shift amount"
	MOVH	R5, (R6)(R2<<3)                                  // ERROR "invalid index shift amount"

        };
    addCallback(f, callback, directExecutor());
  }

  private static final class CountingSameThreadExecutor implements Executor {
    int runCount = 0;

    @Override
    public void execute(Runnable command) {
      command.run();
      runCount++;
    }
  }

  private static final class MockCallback implements FutureCallback<String> {
    @Nullable private String value = null;

   * returns the expected data.
   *
   * @throws Throwable if the listener isn't called or if it resulted in a throwable or if the
   *     result doesn't match the expected value.
   */
  public void assertSuccess(Object expectedData) throws Throwable {
    // Verify that the listener executed in a reasonable amount of time.

{* ../../docs_src/sub_applications/tutorial001_py310.py hl[11, 14:16] *}

### Mount the sub-application { #mount-the-sub-application }

In your top-level application, `app`, mount the sub-application, `subapi`.

In this case, it will be mounted at the path `/subapi`:

{* ../../docs_src/sub_applications/tutorial001_py310.py hl[11, 19] *}

    token: Bearer xxxxx # optional authentication token for the notification endpoint
  
  retry:
    attempts: 10 # number of retries for the job before giving up
    delay: 500ms # least amount of delay between each retry
`
	var job BatchJobRequest
	err := yaml.Unmarshal([]byte(expireYaml), &job)
	if err != nil {
		t.Fatal("Failed to parse batch-job-expire yaml", err)
	}

        };
    addCallback(f, callback, directExecutor());
  }

  private static final class CountingSameThreadExecutor implements Executor {
    int runCount = 0;

    @Override
    public void execute(Runnable command) {
      command.run();
      runCount++;
    }
  }

  private static final class MockCallback implements FutureCallback<String> {
    @Nullable private String value = null;

Bu, bir `APIRouter` kullanmaktan farklıdır; çünkü mount edilen uygulama tamamen bağımsızdır. Ana uygulamanızın OpenAPI ve docs'ları, mount edilen uygulamadan hiçbir şey içermez, vb.
