* You can get metadata from the uploaded file.
* It has a [file-like](https://docs.python.org/3/glossary.html#term-file-like-object) `async` interface.
* It exposes an actual Python [`SpooledTemporaryFile`](https://docs.python.org/3/library/tempfile.html#tempfile.SpooledTemporaryFile) object that you can pass directly to other libraries that expect a file-like object.

### `UploadFile` { #uploadfile }

`UploadFile` has the following attributes:

import org.jspecify.annotations.NullMarked;
import org.jspecify.annotations.Nullable;

/**
 * A class that implements {@code Comparable} without generics, such as those found in libraries
 * that support Java 1.4 and before. Our library needs to do the bare minimum to accommodate such
 * types, though their use may still require an explicit type parameter and/or warning suppression.

Provide code to help us reproduce your issues using one of the following options:

#### Option A: Reference colab notebooks

It would actually be common to use Requests *inside* of a FastAPI application.

But still, FastAPI got quite some inspiration from Requests.

**Requests** is a library to *interact* with APIs (as a client), while **FastAPI** is a library to *build* APIs (as a server).

They are, more or less, at opposite ends, complementing each other.

 * factories for I/O streams that provide many convenience methods that handle both opening and
 * closing streams for you.

它接收一个对象，比如Pydantic模型，并会返回一个JSON兼容的版本：

{* ../../docs_src/encoder/tutorial001_py310.py hl[4,21] *}

在这个例子中，它将Pydantic模型转换为`dict`，并将`datetime`转换为`str`。

调用它的结果后就可以使用Python标准编码中的[`json.dumps()`](https://docs.python.org/3/library/json.html#json.dumps)。

这个操作不会返回一个包含JSON格式（作为字符串）数据的庞大的`str`。它将返回一个Python标准数据结构（例如`dict`），其值和子值都与JSON兼容。

/// note | 注意

`jsonable_encoder`实际上是**FastAPI**内部用来转换数据的。但是它在许多其他场景中也很有用。
