第一个步骤是安装 FastAPI.

请确保您创建并激活一个[虚拟环境](../virtual-environments.md){.internal-link target=_blank}，然后**安装 FastAPI**：

<div class="termy">

```console
$ pip install "fastapi[standard]"

---> 100%
```

</div>

/// note

当您使用 `pip install "fastapi[standard]"` 进行安装时，它会附带一些默认的可选标准依赖项。

如果您不想安装这些可选依赖，可以选择安装 `pip install fastapi`。

Android
=======

For details on developing Go for Android, see the documentation in the
mobile subrepository:

	https://github.com/golang/mobile

To run the standard library tests, enable Cgo and use an appropriate
C compiler from the Android NDK. For example,

	CGO_ENABLED=1 \
	GOOS=android \
	GOARCH=arm64 \
	CC_FOR_TARGET=$NDK/toolchains/llvm/prebuilt/linux-x86_64/bin/aarch64-linux-android21-clang \
	./all.bash

// should be cleared of x-amz-storage-class, if it is set to STANDARD
func TestRemoveStandardStorageClass(t *testing.T) {
	tests := []struct {
		name     string
		metadata map[string]string
		want     map[string]string
	}{
		{
			name:     "1",
			metadata: map[string]string{"content-type": "application/octet-stream", "etag": "de75a98baf2c6aef435b57dd0fc33c86", "x-amz-storage-class": "STANDARD"},

                            "schema": {
                                "anyOf": [{"type": "integer"}, {"type": "null"}],
                                "default": 50,
                                "title": "Standard Query Param",
                            },
                            "name": "standard_query_param",
                            "in": "query",
                        },
                        {

Im Moment müssen Sie nur wissen, dass `Annotated` existiert, und dass es Standard-Python ist. 😎

Später werden Sie sehen, wie **mächtig** es sein kann.

### Storage Class

By default, parity for objects with standard storage class is set to `N/2`, and parity for objects with reduced redundancy storage class objects is set to `2`. Read more about storage class support in MinIO server [here](https://github.com/minio/minio/blob/master/docs/erasure/storage-class/README.md).

```
KEY:
storage_class  define object level redundancy

ARGS:

    assert (
        response.headers["access-control-allow-origin"]
        == "https://localhost.tiangolo.com"
    )
    assert response.headers["access-control-allow-headers"] == "X-Example"

    # Test standard response
    headers = {"Origin": "https://localhost.tiangolo.com"}
    response = client.get("/", headers=headers)
    assert response.status_code == 200, response.text
    assert response.json() == {"message": "Hello World"}
