Bunların hepsi OpenAPI'nize birleştirilerek dahil edilir ve API dokümanlarında gösterilir:

## Ön Tanımlı Response'ları Özel Olanlarla Birleştirme { #combine-predefined-responses-and-custom-ones }

Birçok *path operation* için geçerli olacak bazı ön tanımlı response'larınız olabilir; ancak bunları her *path operation*'ın ihtiyaç duyduğu özel response'larla birleştirmek isteyebilirsiniz.

 * **`CertificatePinner` now supports wildcard hostnames.** As always with
   certificate pinning, you must be very careful to avoid [bricking][brick]
   your app. You'll need to pin both the top-level domain and the `*.` domain
   for full coverage.

    ```java
     client.setCertificatePinner(new CertificatePinner.Builder()
         .add("publicobject.com",   "sha1/DmxUShsZuNiqPQsX2Oi9uv2sCnw=")

Uygulamanızın önündeki bir **proxy**, request'leri **server**'ınıza göndermeden önce genelde bazı header'ları dinamik olarak ayarlar. Böylece server, request'in proxy tarafından **forward** edildiğini; domain dahil orijinal (public) URL'yi, HTTPS kullanıldığını vb. bilgileri anlayabilir.

**Server** programı (örneğin **FastAPI CLI** üzerinden **Uvicorn**) bu header'ları yorumlayabilir ve ardından bu bilgiyi uygulamanıza aktarabilir.

以上都會被結合並包含在你的 OpenAPI 中，並顯示在 API 文件：

## 結合預先定義與自訂的回應 { #combine-predefined-responses-and-custom-ones }

你可能想要有一些適用於多個「路徑操作」的預先定義回應，但也想與每個「路徑操作」所需的自訂回應結合。

在這些情況下，你可以使用 Python 的「解包」`dict` 技巧，透過 `**dict_to_unpack`：

```Python
old_dict = {
    "old key": "old value",

labels.advance_search_occt_default=Anywhere in the page
labels.advance_search_occt_allintitle=in the title of the page
labels.advance_search_occt_allinurl=in the URL of the page
labels.advance_search_sitesearch=Site or domain
labels.advance_search_timestamp=Last update
labels.advance_search_timestamp_default=Anytime
labels.advance_search_timestamp_pastday=Past 24 hours
labels.advance_search_timestamp_pastweek=Past week

    checkNonnegative(k, "k");
    checkNotNull(comparator);
    return Collector.of(
        () -> TopKSelector.<T>least(k, comparator),
        TopKSelector::offer,
        TopKSelector::combine,
        TopKSelector::topK,
        Collector.Characteristics.UNORDERED);
  }

  /**
