## Outros middlewares { #other-middlewares }

Há muitos outros middlewares ASGI.

Por exemplo:

* <a href="https://github.com/encode/uvicorn/blob/master/uvicorn/middleware/proxy_headers.py" class="external-link" target="_blank">Uvicorn's `ProxyHeadersMiddleware`</a>

支持以下参数：

* `minimum_size` - 小于最小字节的响应不使用 GZip。 默认值是 `500`。

## 其它中间件

除了上述中间件外，FastAPI 还支持其它ASGI 中间件。

例如：

* <a href="https://github.com/encode/uvicorn/blob/master/uvicorn/middleware/proxy_headers.py" class="external-link" target="_blank">Uvicorn 的 `ProxyHeadersMiddleware`</a>

    private long reserved;  // Must be zero
    
    public DurableHandleRequest() {
        super(NAME);
        this.reserved = 0;
    }
    
    @Override
    public void encode(byte[] buffer, int offset) {
        // Context header
        int nameLen = getName().length();
        writeInt4(buffer, offset, 16);  // Next
        writeInt2(buffer, offset + 4, nameLen);  // NameOffset

## Other middlewares { #other-middlewares }

There are many other ASGI middlewares.

For example:

* <a href="https://github.com/encode/uvicorn/blob/master/uvicorn/middleware/proxy_headers.py" class="external-link" target="_blank">Uvicorn's `ProxyHeadersMiddleware`</a>
