val request = Request.Builder()

    To avoid making many retries when authentication isn't working, you can return null to give up. For example, you may want to skip the retry when these exact credentials have already been attempted:

    ```kotlin
    if (credential == response.request.header("Authorization")) {

  `It must have been that,' said the King, `unless it was
written to nobody, which isn't usual, you know.'

  `Who is it directed to?' said one of the jurymen.

  `It isn't directed at all,' said the White Rabbit; `in fact,
there's nothing written on the OUTSIDE.'  He unfolded the paper
as he spoke, and added `It isn't a letter, after all:  it's a set
of verses.'

 *  New: Drop the `tunnelProxy` argument in `MockWebServer.useHttps()`. This change only impacts
    the OkHttp 5.x API which uses the `mockwebserver3` package.
 *  Fix: Don't call `toDuration()` which isn't available in kotlin-stdlib 1.4.


## Version 5.0.0-alpha.8

_2022-06-08_

 *  Fix: Change how `H2_PRIOR_KNOWLEDGE` works with HTTP proxies. Previously OkHttp assumed the

  /** Consider this connection to be unhealthy if a degraded pong isn't received by this time. */

            // Likewise, the file to compile may be contained in a "platform" multiplatform module, where the `actual` declaration is
            // referenced in the symbol table automatically, but not its `expect` counterpart, because it isn't contained in the files to
            // compile. `shouldReferenceUndiscoveredExpectSymbols` references such `expect` symbols in the symbol table so that they can
            // subsequently be stubbed.

## 面向开发人员的 HTTPS

这里有一个 HTTPS API 看起来是什么样的示例，我们会分步说明，并且主要关注对开发人员重要的部分。


### 域名

第一步我们要先**获取**一些**域名(Domain Name)**。 然后可以在 DNS 服务器（可能是你的同一家云服务商提供的）中配置它。

你可能拥有一个云服务器（虚拟机）或类似的东西，并且它会有一个<abbr title="That isn't Change">固定</abbr> **公共IP地址**。

在 DNS 服务器中，你可以配置一条记录（“A 记录”）以将 **你的域名** 指向你服务器的公共 **IP 地址**。

这个操作一般只需要在最开始执行一次。

!!! tip
     域名这部分发生在 HTTPS 之前，由于这一切都依赖于域名和 IP 地址，所以先在这里提一下。

### DNS

                    is FirResolvedNamedReference -> when (calleeReference.resolvedSymbol) {
                        // `calleeReference.resolvedSymbol` isn't guaranteed to be callable. For example, function type parameters used in
                        // expression positions (e.g. `T` in `println(T)`) are parsed as `KtSimpleNameExpression` and built into

 *  Fix: Don't crash decompressing web sockets messages. We had a bug where we assumed deflated
    bytes in would always yield deflated bytes out and this isn't always the case!

 *  Fix: Reliably update and invalidate the disk cache on windows. As originally designed our
    internal `DiskLruCache` assumes an inode-like file system, where it's fine to delete files that

This isn't even Python, NestJS is a JavaScript (TypeScript) NodeJS framework inspired by Angular.

It achieves something somewhat similar to what can be done with Flask-apispec.
