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>

			switch b {
			case '\\', '"':
				dst.WriteByte(b)
			case '\n':
				dst.WriteByte('n')
			case '\r':
				dst.WriteByte('r')
			case '\t':
				dst.WriteByte('t')
			default:
				// This encodes bytes < 0x20 except for \t, \n and \r.
				// If escapeHTML is set, it also escapes <, >, and &
				// because they can lead to security holes when
				// user-controlled strings are rendered into JSON
