The main limitation is that to update or delete content of a file inside a ZIP file the entire ZIP file must be replaced.

## How to enable S3 ZIP behavior ?

Ensure to set the following header `x-minio-extract` to `true` in your S3 requests.

## How to access to files inside a ZIP archive

//
// A TensorHandle is management class around a Tensor which may track additional
// metadata and synchronization.
//
// This allows us to hide concrete implementations of TensorHandle from header
// files. The interface lists the common functionality that must be provided by
// any concrete implementation. However, in cases where the true concrete class
// is needed a static_cast can be applied.

So we put them in their own `dependencies` module (`app/dependencies.py`).

We will now use a simple dependency to read a custom `X-Token` header:

## 使用 `Depends` 和其他依赖项

在 WebSocket 端点中，您可以从 `fastapi` 导入并使用以下内容：

* `Depends`
* `Security`
* `Cookie`
* `Header`
* `Path`
* `Query`

它们的工作方式与其他 FastAPI 端点/ *路径操作* 相同：
