做两个请求.这允许每个表示具有不同的缓存规则.缓存国家/地区列表可能是个好主意.

Do two requests. This allows each representation to have difference caching rules. Caching the country list is probably a good idea.

当我这样做时，我的 XML 表示如下:

When I do this, my XML representation looks like:

<User>
    <Name>Bob Brown</Name>
    <Country DomainUrl="/Setup/Country/PickList">
      <Code>US</Code>
      <Description>United States</Description>
    </Country>
</User>

我还推迟加载国家/地区列表，直到用户实际单击下拉列表.

I also defer the loading of the Country list until the user actually clicks on the drop down.
