## Pydantic v1 in v2 { #pydantic-v1-in-v2 }

Pydantic v2 includes everything from Pydantic v1 as a submodule `pydantic.v1`. But this is no longer supported in versions above Python 3.13.

This means that you can install the latest version of Pydantic v2 and import and use the old Pydantic v1 components from this submodule, as if you had the old Pydantic v1 installed.

# FastAPI CLI

**FastAPI CLI** 是一個命令列程式，能用來運行你的 FastAPI 應用程式、管理你的 FastAPI 專案等。

當你安裝 FastAPI（例如使用 `pip install "fastapi[standard]"`），它會包含一個叫做 `fastapi-cli` 的套件，這個套件提供了 `fastapi` 命令。

要運行你的 FastAPI 應用程式來進行開發，你可以使用 `fastapi dev` 命令：

<div class="termy">

```console
$ <font color="#4E9A06">fastapi</font> dev <u style="text-decoration-style:single">main.py</u>
<font color="#3465A4">INFO    </font> Using path <font color="#3465A4">main.py</font>

            }

            sb.append(LS);
            sb.append(LS);
            sb.append(indentation);
            sb.append("Then, install it using the command: ");
            sb.append(LS);
            sb.append(indentation);
            sb.append("    mvn install:install-file -DgroupId=");
            sb.append(groupId);

produce the work, or an object code interpreter used to run it.

  The "Corresponding Source" for a work in object code form means all
the source code needed to generate, install, and (for an executable
work) run the object code and to modify the work, including scripts to
control those activities.  However, it does not include the work's

Переконайтеся, що Ви створили [віртуальне середовище](../virtual-environments.md){.internal-link target=_blank}, активували його та встановили пакет, наприклад:

```console
$ pip install python-multipart

## Імпорт `File`

Імпортуйте `File` та `UploadFile` з `fastapi`:

                        anonymous = true;
                    }

                    if (request.getDigest() != null) {
                        /* success - install the signing digest */
                        log.debug("Setting digest");
                        setDigest(request.getDigest());
                    }

                    token = response.getBlob();
