* Though any call may be initiated as a duplex call, only web servers that are specially
   * designed for this nonstandard interaction will use it. As of 2019-01, the only widely-used
   * implementation of this pattern is [gRPC][grpc].

   * Because the encoding of interleaved data is not well-defined for HTTP/1, duplex request
   * bodies may only be used with HTTP/2. Calls to HTTP/1 servers will fail before the HTTP request

## Container Installation

Use the following commands to run a standalone MinIO server as a container.

Standalone MinIO servers are best suited for early development and evaluation. Certain features such as versioning, object locking, and bucket replication

## 附加的服务器

/// warning | "警告"

此用例较难，可以跳过。

///

默认情况下，**FastAPI** 使用 `root_path` 的链接在 OpenAPI 概图中创建 `server`。

但也可以使用其它备选 `servers`，例如，需要同一个 API 文档与 staging 和生产环境交互。

如果传递自定义 `servers` 列表，并有 `root_path`（ 因为 API 使用了代理），**FastAPI** 会在列表开头使用这个 `root_path` 插入**服务器**。

例如：

```Python hl_lines="4-7"
{!../../docs_src/behind_a_proxy/tutorial003.py!}
```
