## Install `PyJWT` { #install-pyjwt }

We need to install `PyJWT` to generate and verify the JWT tokens in Python.

Make sure you create a [virtual environment](../../virtual-environments.md){.internal-link target=_blank}, activate it, and then install `pyjwt`:

<div class="termy">

```console
$ pip install pyjwt

---> 100%
```

```Python
from unicorn import UnicornMiddleware

app = SomeASGIApp()

new_app = UnicornMiddleware(app, some_config="rainbow")
```

But FastAPI (actually Starlette) provides a simpler way to do it that makes sure that the internal middlewares handle server errors and custom exception handlers work properly.

For that, you use `app.add_middleware()` (as in the example for CORS).

```Python
from fastapi import FastAPI

                copyOfArray2[j] = o2;
            }
        }
        return true;
    }

    /**
     * Converts an array to an object array ({@literal Object[]}).
     * <p>
     * The source array can be a primitive array. In that case, the resulting array will contain the corresponding wrapper types.
     * </p>
     *
     * @param array
     *            the array
     * @return the object array

        for (int i = 0; i < num; i++) {
            Map<String, Object> source = Collections.singletonMap("content", "test");
            IndexRequestBuilder indexRequestBuilder = new IndexRequestBuilder(client, IndexAction.INSTANCE);
            indexRequestBuilder.setIndex(indexName).setId(String.valueOf(i)).setCreate(true).setSource(source);
            bulkRequestBuilder.add(indexRequestBuilder);
        }

For large responses, returning a `Response` directly is much faster than returning a dictionary.

This is because by default, FastAPI will inspect every item inside and make sure it is serializable as JSON, using the same [JSON Compatible Encoder](../tutorial/encoder.md){.internal-link target=_blank} explained in the tutorial. This is what allows you to return **arbitrary objects**, for example database models.

        // to currentFuture doesn't race with itself so that currentFuture is assigned in the
        // correct order.
