# FastAPI CLI { #fastapi-cli }

**FastAPI <abbr title="command line interface - 命令行接口">CLI</abbr>** 是一个命令行程序，你可以用它来部署和运行你的 FastAPI 应用、管理 FastAPI 项目，等等。

当你安装 FastAPI（例如使用 `pip install "fastapi[standard]"`）时，会附带一个可以在终端中运行的命令行程序。

要在开发环境中运行你的 FastAPI 应用，可以使用 `fastapi dev` 命令：

<div class="termy">

```console
$ <font color="#4E9A06">fastapi</font> dev

          println("TLSv1.2 traffic will be logged automatically and available via wireshark")
        }

        if (tlsVersions.contains(TLS_1_3)) {
          println("TLSv1.3 requires an external command run before first traffic is sent")
          println("Follow instructions at https://github.com/neykov/extract-tls-secrets for TLSv1.3")
          println("Pid: ${ProcessHandle.current().pid()}")

          Thread.sleep(10000)

    /** Process ID */
    int PID = (int) (Math.random() * 65536d);

    /** Share level security */
    int SECURITY_SHARE = 0x00;
    /** User level security */
    int SECURITY_USER = 0x01;

    /** Command offset in SMB header */
    int CMD_OFFSET = 4;
    /** Error code offset in SMB header */
    int ERROR_CODE_OFFSET = 5;
    /** Flags offset in SMB header */
    int FLAGS_OFFSET = 9;

/**
 * JUnit 5 tests for {@link TestLocking}.
 * Tests command line argument parsing and basic field initialization.

# 手動執行伺服器 { #run-a-server-manually }

## 使用 `fastapi run` 指令 { #use-the-fastapi-run-command }

簡而言之，使用 `fastapi run` 來啟動你的 FastAPI 應用：

<div class="termy">

```console
$ <font color="#4E9A06">fastapi</font> run <u style="text-decoration-style:solid">main.py</u>

  <span style="background-color:#009485"><font color="#D3D7CF"> FastAPI </font></span>  Starting production server 🚀

             Searching for package file structure from directories

Create new canned policy file `getonly.json`. This policy enables users to download all objects under `my-bucketname`.

```json
cat > getonly.json << EOF
{
  "Version": "2012-10-17",
  "Statement": [

Importez les modules installés.

Créez une clé secrète aléatoire qui sera utilisée pour signer les jetons JWT.

Pour générer une clé secrète aléatoire sécurisée, utilisez la commande :

<div class="termy">

```console
$ openssl rand -hex 32

```

</div>

    # Comment with indentation
    print("Hello, world!")  # Print greeting
```

```toml
# This is a sample TOML code block
title = "TOML Example"  # Title of the document
```

```console
// Use the command "live" and pass the language code as a CLI argument
$ python ./scripts/docs.py live es

	// Captures site name and region
	globalSite config.Site

	// MinIO local server address (in `host:port` format)
	globalMinioAddr = ""

	// MinIO default port, can be changed through command line.
	globalMinioPort        = GlobalMinioDefaultPort
	globalMinioConsolePort = "13333"

	// Holds the host that was passed using --address
	globalMinioHost = ""

A smaller CPU-only TensorFlow package is also available:

```
 pip install tensorflow-cpu
```

To update TensorFlow to the latest version, add the `--upgrade` flag to the
commands above.

*Nightly binaries are available for testing using the
[tf-nightly](https://pypi.python.org/pypi/tf-nightly) and
[tf-nightly-cpu](https://pypi.python.org/pypi/tf-nightly-cpu) packages on PyPI.*
