没有任何后端操作执行 “预订旅行”这个语义。
Originally, the purpose of this header was to identify the intent of the request — the operation to be invoked on the back end.
最初，这个头主要是用来识别请求意图——后台所调用的操作。
In our example, the back end web service offers only one operation.
在我们的例子中，后台服务仅提供一个操作。

方法4也存在同样的问题——如果服务后台包含一个以上的操作，那么它可能也不是最佳方法。
Say if you want to do custom operation from other end of the world, like back up certain files, retrieve your file from any where, configure your custom build software, etc.
如果说你想从世界的另一端做自定操作，像备份某些文件，从任何地方获取你的文件，配置你的自定义生成软件等。
