/// tip | Подсказка

Возможно, вам понадобится, чтобы параметр содержал `/home/johndoe/myfile.txt` с ведущим слэшем (`/`).

В этом случае URL будет таким: `/files//home/johndoe/myfile.txt`, с двойным слэшем (`//`) между `files` и `home`.

             Searching for package file structure from directories

                }
                script {
                    name = "CLEAN_M2"
                    executionMode = BuildStep.ExecutionMode.ALWAYS
                    scriptContent = checkCleanDirUnixLike("%teamcity.agent.jvm.user.home%/.m2/.develocity", exitOnFailure = false)
                }
            }
        },

После активации виртуального окружения переменная `PATH` будет выглядеть примерно так:

//// tab | Linux, macOS

```plaintext
/home/user/code/awesome-project/.venv/bin:/usr/bin:/bin:/usr/sbin:/sbin
```

Это означает, что теперь система в первую очередь будет искать программы в:

```plaintext
/home/user/code/awesome-project/.venv/bin
```

прежде чем искать в других директориях.

```

本例中，参数名为 `file_path`，结尾部分的 `:path` 说明该参数应匹配*路径*。

用法如下：

{* ../../docs_src/path_params/tutorial004.py hl[6] *}

/// tip | 提示

注意，包含 `/home/johndoe/myfile.txt` 的路径参数要以斜杠（`/`）开头。

本例中的 URL 是 `/files//home/johndoe/myfile.txt`。注意，`files` 和 `home` 之间要使用**双斜杠**（`//`）。

## 小结

通过简短、直观的 Python 标准类型声明，**FastAPI** 可以获得：

- 编辑器支持：错误检查，代码自动补全等

{* ../../docs_src/path_params/tutorial004_py39.py hl[6] *}

/// tip | Dica
Você pode precisar que o parâmetro contenha `/home/johndoe/myfile.txt`, com uma barra inicial (`/`).

Nesse caso, a URL seria: `/files//home/johndoe/myfile.txt`, com uma barra dupla (`//`) entre `files` e `home`.

## Recapitulação { #recap }

Com o **FastAPI**, ao usar declarações de tipo do Python curtas, intuitivas e padrão, você obtém:
