是否有任何方法可以获取Ajax.BeginForm以输出绝对URL 而不只是亲戚?

是的，但是您需要在AjaxOptions中指定Url，而不要使用具有操作和控制器名称的重载:

Yes, but you need to specify the Url in the AjaxOptions and not use the overload which takes action and controller names:

@using (Ajax.BeginForm(new AjaxOptions { Url = Url.Action("Foo", "Bar", null, "http") }))
{
    ...
}

Url.Action有一个重载，您可以在其中指定要使用的生成绝对URL的协议.而且，如果您要使用与请求当前操作所用的协议相同的协议，而不是对其进行硬编码，则可以使用以下协议:

Url.Action has an overload where you could specify the protocol to be used which generates absolute urls. And if you wanted to use the same protocol as the one used to request the current action instead of hardcoding it you could use the following:

@using (Ajax.BeginForm(new AjaxOptions { Url = Url.Action("Foo", "Bar", null, Request.Url.Scheme) }))
{
    ...
}
