## 其他 servers { #additional-servers }

/// warning

這是更進階的用法。你可以選擇略過。

///

預設情況下，FastAPI 會在 OpenAPI 模式中建立一個 `server`，其 URL 為 `root_path`。

但你也可以另外提供其他 `servers`，例如你想要用「同一份」文件 UI 來與測試（staging）與正式（production）環境互動。

如果你傳入自訂的 `servers` 清單，且同時存在 `root_path`（因為你的 API 位於代理之後），FastAPI 會在清單開頭插入一個 `server`，其 URL 為該 `root_path`。

例如：

{* ../../docs_src/behind_a_proxy/tutorial003_py310.py hl[4:7] *}

* **Sağlam**: Production'a hazır kod elde edersiniz. Otomatik etkileşimli dokümantasyon ile birlikte.
* **Standardlara dayalı**: API'lar için açık standartlara dayalıdır (ve tamamen uyumludur); [OpenAPI](https://github.com/OAI/OpenAPI-Specification) (önceden Swagger olarak biliniyordu) ve [JSON Schema](https://json-schema.org/).

        byte[] clientChallenge = hex("0102030405060708");
        long nanos1601 = 0x1122334455667788L;
        byte[] avPairs = hex("A1A2A3A4");

        // Manually build the expected NTLMv2 blob (same as production code)
        int avPairsLength = avPairs.length;
        byte[] blob = new byte[28 + avPairsLength + 4];
        Encdec.enc_uint32le(0x00000101, blob, 0); // Header

### 2. Infrastructure Requirements

Ensure your Fess environment meets these requirements:

- **Java**: JDK 17 or later
- **Memory**: Minimum 4GB RAM (8GB+ recommended for production)
- **Storage**: At least 2x your current index size
- **Network**: Access to crawl sources (web servers, file shares, databases)
- **Elasticsearch/OpenSearch**: Compatible version running

### 3. Backup Existing System

     | An encouraged best practice for profile identification is to use a consistent naming convention
     | for profiles, such as 'env-dev', 'env-test', 'env-production', 'user-jdcasey', 'user-brett', etc.
     | This will make it more intuitive to understand what the set of introduced profiles is attempting
     | to accomplish, particularly when you only have a list of profile id's for debug.

## Starlette features { #starlette-features }

**FastAPI** is fully compatible with (and based on) [**Starlette**](https://www.starlette.dev/). So, any additional Starlette code you have, will also work.
