 *  **The DNS service is now pluggable.** In some situations this may be useful
    to manually prioritize specific IP addresses.

 *  Fix: Don't throw when converting an `HttpUrl` to a `java.net.URI`.
    Previously URLs with special characters like `|` and `[` would break when
    subjected to URI’s overly-strict validation.
 *  Fix: Don't re-encode `+` as `%20` in encoded URL query strings. OkHttp

We can see that we were redirected because `response.request().url()` is different from `request.url()`. The two log statements log two different URLs.

### Network Interceptors

Registering a network interceptor is quite similar. Call `addNetworkInterceptor()` instead of `addInterceptor()`:

```java
OkHttpClient client = new OkHttpClient.Builder()

            } catch( IOException ioe ) {
            }
        }
    }

    /**
     * This static method registers the SMB URL protocol handler which is
     * required to use SMB URLs with the <tt>java.net.URL</tt> class. If this
     * method is not called before attempting to create an SMB URL with the
     * URL class the following exception will occur:
     * <blockquote><pre>

 * `COMPATIBLE_TLS` is a secure configuration that connects to secure–but not current–HTTPS servers.
 * `CLEARTEXT` is an insecure configuration that is used for `http://` URLs.

These loosely follow the model set in [Google Cloud Policies](https://cloud.google.com/load-balancing/docs/ssl-policies-concepts). We [track changes](../security/tls_configuration_history.md) to this policy.

Die meisten dieser Einstellungen sind variabel (können sich ändern), wie z. B. Datenbank-URLs. Und vieles könnten schützenswerte, geheime Daten sein.

Aus diesem Grund werden diese üblicherweise in Umgebungsvariablen bereitgestellt, die von der Anwendung gelesen werden.

/// tip | "Tipp"

这部分代码很常规，您对绝大多数代码应该都比较熟悉了：

```Python hl_lines="10-14  37-54"
{!../../docs_src/openapi_callbacks/tutorial001.py!}
```

/// tip | "提示"

`callback_url` 查询参数使用 Pydantic 的 <a href="https://pydantic-docs.helpmanual.io/usage/types/#urls" class="external-link" target="_blank">URL</a> 类型。

此处唯一比较新的内容是*路径操作装饰器*中的 `callbacks=invoices_callback_router.routes` 参数，下文介绍。

## 存档回调

实际的回调代码高度依赖于您自己的 API 应用。

并且可能每个应用都各不相同。
