PortalUtil.getOriginalServletRequest和PortalUtil.getHttpServletRequest有什么区别? [英] What is the difference between PortalUtil.getOriginalServletRequest and PortalUtil.getHttpServletRequest?

问题描述

我想知道

PortalUtil.getOriginalServletRequest(portletRequest) 

和

PortalUtil.getHttpServletRequest(portletRequest).

推荐答案

查看Liferay 6的源代码(假设您正在谈论6)，您可以看到PortalUtil.getOriginalServletRequest所做的工作并将其放置在下面的代码:

Looking at the source code for Liferay 6 (I'm assuming your're talking about 6) you can see what PortalUtil.getOriginalServletRequest does and I've placed the code below:

public HttpServletRequest getOriginalServletRequest(
    HttpServletRequest request) {

    HttpServletRequest originalRequest = request;

    while (originalRequest.getClass().getName().startsWith(
                "com.liferay.")) {

        // Get original request so that portlets inside portlets render
        // properly

        originalRequest = (HttpServletRequest)
            ((HttpServletRequestWrapper)originalRequest).getRequest();
    }

    return originalRequest;
}

因此，正如评论所述，获取原始请求，以便正确呈现portlet中的portlet".对于嵌套的portlet情况或类似情况，您可能只需要这样做.大多数时候，您只需要使用:

So as the comment says, "Get original request so that the portlets inside portlets render properly". You'll probably only require this for a nested portlet situation or similar. Most of the time you will just need to use:

PortalUtil.getHttpServletRequest(portletRequest);

我希望这会有所帮助！
