### Bereitstellung des `root_path` { #providing-the-root-path }

Um dies zu erreichen, können Sie die Kommandozeilenoption `--root-path` wie folgt verwenden:

<div class="termy">

```console
$ fastapi run main.py --forwarded-allow-ips="*" --root-path /api/v1

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)

    }

    /**
     * Returns {@literal true} if the array is not {@literal null} and its length is not 0.
     *
     * @param <T>
     *            the type of the array elements
     * @param arrays
     *            the array
     * @return {@literal true} if the array is not {@literal null} and its length is not 0
     */
    public static <T> boolean isNotEmpty(final T[] arrays) {

            // Then
            assertNotNull(os1, "Default output stream should not be null");
            assertNotNull(os2, "Output stream with append should not be null");
            assertNotNull(os3, "Output stream with sharing should not be null");
            assertNotNull(os4, "Output stream with full params should not be null");
            assertSame(mockOutputStream, os1, "Should return expected output stream");

from fastapi.testclient import TestClient

app = FastAPI()

    return state

      Object source)
      throws ConflictingRequirementsException {
    if (!disjoint(newFeatures, earlierFeatures)) {
      throw new ConflictingRequirementsException(
          String.format(
              Locale.ROOT,

            Map<String, Object> pngDocMap = new HashMap<>();
            pngDocMap.put("thumbnail", "http://example.com/image.png");
            pngDocMap.put("mimetype", "image/png");
            assertFalse("PNG MIME type should not be target", generator.isTarget(pngDocMap));

            // Test case 3: Missing thumbnail field should not match

* fix: make azure disk URI as case insensitive...

				// If the object is not modified since the specified time.
				writeHeaders()
				writeErrorResponse(ctx, w, errorCodes.ToAPIErr(ErrPreconditionFailed), r.URL)
				return true
			}
		}
	}

	// x-amz-copy-source-if-unmodified-since : Return the object only if it has not been
	// modified since the specified time, otherwise return a 412 (precondition failed).

### 提供 `root_path` { #providing-the-root-path }

为此，你可以像下面这样使用命令行选项 `--root-path`：

<div class="termy">

```console
$ fastapi run main.py --forwarded-allow-ips="*" --root-path /api/v1

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

如果你使用 Hypercorn，它也有 `--root-path` 选项。
