    * HTTP Basic 认证方式。
    * HTTP Digest，等等。
* `oauth2`：所有的 OAuth2 处理安全性的方式（称为「流程」）。
    *以下几种流程适合构建 OAuth 2.0 身份认证的提供者（例如 Google，Facebook，Twitter，GitHub 等）：
        * `implicit`
        * `clientCredentials`
        * `authorizationCode`
    * 但是有一个特定的「流程」可以完美地用于直接在同一应用程序中处理身份认证：
        * `password`：接下来的几章将介绍它的示例。
* `openIdConnect`：提供了一种定义如何自动发现 OAuth2 身份认证数据的方法。

Entrust and Verisign.

This is the behavior you'll get with your OkHttpClient if you don't specifically configure
`HandshakeCertificates`. Or you can do it explicitly with `addPlatformTrustedCertificates()`:

```java
HandshakeCertificates clientCertificates = new HandshakeCertificates.Builder()
    .addPlatformTrustedCertificates()
    .build();

Of course, you can also declare additional query parameters whenever you need, additional to any body parameters.

As, by default, singular values are interpreted as query parameters, you don't have to explicitly add a `Query`, you can just do:

```Python
q: Union[str, None] = None
```

Or in Python 3.10 and above:

```Python
q: str | None = None
```

For example:

  }

  /**
   * Shortens the last frame from its original length to `length`. This will cause the peer to
   * close the socket as soon as this frame has been written; otherwise the peer stays open until
   * explicitly closed.
   */
  fun truncateLastFrame(length: Int): Http2Writer {
    val lastFrame = outFrames.removeAt(outFrames.size - 1)
    require(length < bytesOut.size - lastFrame.start)
