You can define background tasks to be run *after* returning a response.

This is useful for operations that need to happen after a request, but that the client doesn't really have to be waiting for the operation to complete before receiving the response.

This includes, for example:

* Email notifications sent after performing an action:

<div class="termy">

```console
$ python ./scripts/docs.py live

<span style="color: green;">[INFO]</span> Serving on http://127.0.0.1:8008
<span style="color: green;">[INFO]</span> Start watching changes
<span style="color: green;">[INFO]</span> Start detecting changes
```

</div>

    // retry, we return true and try a new route.
    return true
  }

  /**
   * Figures out the HTTP request to make in response to receiving [userResponse]. This will
   * either add authentication headers, follow redirects or handle a client request timeout. If a
   * follow-up is either unnecessary or not applicable, this returns null.
   */

        if ( upper ) {
            dfsShare = dfsShare.toUpperCase(Locale.ROOT);
            path = path.toUpperCase(Locale.ROOT);
            target = target.toUpperCase(Locale.ROOT);
        }

        log.debug("Resolving \\" + target + "\\" + dfsShare + path);
        DfsReferralData ref = dfs.resolve(context, target, dfsShare, path);

        if ( ref != null ) {
            do {
                log.debug("ref " + ref);

				b.ReportAllocs()
				for i := 0; i < b.N; i++ {
					// Load...
					xl = xlMetaV2{}
					err := xl.Load(enc)
					if err != nil {
						b.Fatal(err)
					}
					// Update modtime for resorting...
					fi.ModTime = fi.ModTime.Add(-time.Second)
					// Update a random version.
					fi.VersionID = ids[rng.Intn(size)]
					// Update...
					err = xl.UpdateObjectVersion(fi)
					if err != nil {

   * This was misleading for tracing because it was too early.
   */
  open fun responseHeadersStart(call: Call) {
  }

  /**
   * Invoked immediately after receiving response headers.
   *
   * This method is always invoked after [responseHeadersStart].
   *
   * @param response the response received over the network. It is an error to access the body of
   *     this response.

                                 n_ask_attempts=_DEFAULT_PROMPT_ASK_ATTEMPTS):
  """Loop over user prompts for an ENV param until receiving a valid response.

  For the env param var_name, read from the environment or verify user input
  until receiving valid input. When done, set var_name in the environ_cp to its
  new value.

  Args:
    environ_cp: (Dict) copy of the os.environ.

        final ResourceHandler resource_handler = new ResourceHandler();
        resource_handler.setWelcomeFiles(new String[] { "index.html" });
        resource_handler.setResourceBase(docRoot.getAbsolutePath());
        Log.info("serving " + resource_handler.getBaseResource());
        final HandlerList handlers = new HandlerList();
        handlers.setHandlers(new Handler[] { resource_handler, new DefaultHandler() });
        server.setHandler(handlers);
    }

首先，请确保按上述步骤设置好环境，这将安装所有需要的依赖。

### 实时文档

在本地开发时，可以使用该脚本构建站点并检查所做的任何更改，并实时重载：

<div class="termy">

```console
$ python ./scripts/docs.py live

<span style="color: green;">[INFO]</span> Serving on http://127.0.0.1:8008
<span style="color: green;">[INFO]</span> Start watching changes
<span style="color: green;">[INFO]</span> Start detecting changes
```

</div>

文档服务将运行在 `http://127.0.0.1:8008`。
