Swagger UI will handle it behind the scenes for you, but it needs this "redirect" helper.

### Create a *path operation* to test it { #create-a-path-operation-to-test-it }

Now, to be able to test that everything works, create a *path operation*:

{* ../../docs_src/custom_docs_ui/tutorial001_py310.py hl[36:38] *}

### Test it { #test-it }

### Async Olmayan Path Operation Function'lar { #non-async-path-operation-functions }

Normal `def` fonksiyonlarını (yani `async` olmadan) da kullanabilir ve aynı şekilde `yield` yazabilirsiniz.

{* ../../docs_src/stream_data/tutorial001_py310.py ln[26:29] hl[27] *}

### Tip Annotasyonu Yok { #no-annotation }

			Description: `maximum sleep duration between objects to slow down batch replication operation` + defaultHelpPostfix(ReplicationWorkersWait),
			Optional:    true,
			Type:        "duration",
		},
		config.HelpKV{
			Key:         KeyRotationWorkersWait,
			Description: `maximum sleep duration between objects to slow down batch keyrotation operation` + defaultHelpPostfix(KeyRotationWorkersWait),
			Optional:    true,
			Type:        "duration",

 * It keeps track of any failures that occur during the operation.

public class SuggestWriterResult {
    /**
     * Constructs a new {@link SuggestWriterResult}.
     */
    public SuggestWriterResult() {
        // nothing
    }

    /**
     * A list of Throwables representing failures that occurred during the operation.
     */

But we can still add _more_ `tags` that will be applied to a specific *path operation*, and also some extra `responses` specific to that *path operation*:

{* ../../docs_src/bigger_applications/app_an_py310/routers/items.py hl[30:31] title["app/routers/items.py"] *}

/// tip

If you declare a `response_class=StreamingResponse` in your *path operation function*, you can use `yield` to send each chunk of data in turn.

{* ../../docs_src/stream_data/tutorial001_py310.py ln[1:23] hl[20,23] *}

FastAPI will give each chunk of data to the `StreamingResponse` as is, it won't try to convert it to JSON or anything similar.

# 全域依賴 { #global-dependencies }

在某些類型的應用程式中，你可能想為整個應用程式新增依賴。

類似於你可以在[路徑操作（path operation）的裝飾器中新增 `dependencies`](dependencies-in-path-operation-decorators.md) 的方式，你也可以把它們加到 `FastAPI` 應用程式上。

在這種情況下，它們會套用到應用程式中的所有路徑操作：

{* ../../docs_src/dependencies/tutorial012_an_py310.py hl[17] *}

而且，在[將 `dependencies` 新增到路徑操作裝飾器](dependencies-in-path-operation-decorators.md) 那一節中的所有概念依然適用，只是這裡是套用到整個應用中的所有路徑操作。

        assertEquals(-1, smbRandomAccessFile.getFilePointer());
