## Using `Union` or `Optional` { #using-union-or-optional }

If your code for some reason can't use `|`, for example if it's not in a type annotation but in something like `response_model=`, instead of using the vertical bar (`|`) you can use `Union` from `typing`.

For example, you could declare that something could be a `str` or `None`:

```python
from typing import Union


def say_hi(name: Union[str, None]):

        assertSame(name1, name2); // Should be same instance
    }

    /**
     * Test searcher with simple class name.
     */
    @Test
    public void test_simpleClassNameSearcher() {
        final SimpleSearcher searcher = new SimpleSearcher();
        assertEquals("simple", searcher.getName());
    }

    /**
     * Test searcher extending another searcher.
     */
    @Test

        final Map<String, Object> attributes = new HashMap<>();

        authenticator.parseJwtClaim(jwtClaim, attributes);

        assertEquals("user123", attributes.get("sub"));
        assertEquals("John Doe", attributes.get("name"));
        assertEquals("john@example.com", attributes.get("email"));
    }

    @Test

    ## Usage

    Create an instance object and use that object as the dependency in `Depends()`.

    The dependency result will be a string containing the key value.

    ## Example

    ```python
    from fastapi import Depends, FastAPI
    from fastapi.security import APIKeyQuery

    app = FastAPI()

    query_scheme = APIKeyQuery(name="api_key")


    @app.get("/items/")

        // Test characters that need special encoding
        String input1 = "http://example.com/文档"; // Unicode characters
        String result1 = crawlingInfoHelper.generateId(input1);
        assertNotNull(result1);
        assertEquals(128, result1.length());

        String input2 = "http://example.com/path with spaces";
        String result2 = crawlingInfoHelper.generateId(input2);

As all these methods are `async` methods, you need to "await" them.

For example, inside of an `async` *path operation function* you can get the contents with:

```Python
contents = await myfile.read()
```

If you are inside of a normal `def` *path operation function*, you can access the `UploadFile.file` directly, for example:

```Python
contents = myfile.file.read()
```
