使GWT应用程序可以通过搜索引擎进行抓取 [英] Making GWT application crawlable by a search engine

问题描述

我想使用＃！令牌使我的GWT应用程序可以被抓取，如下所述：
http://code.google.com/web/ajaxcrawling/

I want to use the #! token to make my GWT application crawlable, as described here: http://code.google.com/web/ajaxcrawling/

有是一个可以在线使用的GWT示例应用程序，例如：
http://gwt.google.com/samples/Showcase/Showcase.html#!CwRadioButton

There is a GWT sample app available online that uses this, for example: http://gwt.google.com/samples/Showcase/Showcase.html#!CwRadioButton

将以下静态网页投放到Googlebot：
http://gwt.google.com/samples/ Showcase / Showcase.html？_escaped_fragment_ = CwRadioButton

Will serve the following static webpage to the googlebot: http://gwt.google.com/samples/Showcase/Showcase.html?_escaped_fragment_=CwRadioButton

我希望我的GWT应用程序能够做类似的事情。简而言之，只要在URL中找到 _escaped_fragment _ 参数，我就想为页面提供不同的风格。

I want my GWT app to do something similar. In short, I'd like to serve a different flavor of the page whenever the _escaped_fragment_ parameter is found in the URL.

我应该修改哪些内容才能让服务器提供其他内容（静态页面或通过无头浏览器动态生成的页面，如 HTML单元）？我猜它可能是 web.xml 文件，但我不确定。

What should I modify in order for the server to serve something else (a static page, or a page dynamically generated through a headless browser like HTML Unit)? I'm guessing it could be the web.xml file, but I'm not sure.

（注意：我想检查GWT SDK提供的Showcase应用程序，但不幸的是它似乎不支持在 _escaped_fragment _ 并且它不使用＃！标记..）

(Note: I thought of checking the Showcase app provided with the GWT SDK, but unfortunately it doesn't seem to support serving static files on _escaped_fragment_ and it doesn't use the #! token..)

推荐答案

找到我的答案！ Showcase 支持可抓取超链接的示例位于以下分支中：
http://code.google.com/p/google-web-toolkit/source/browse/branches/ crawlbility / samples / showcase /？r = 7726

Found my answer! The Showcase sample supporting crawlable hyperlinks is in the following branch: http://code.google.com/p/google-web-toolkit/source/browse/branches/crawlability/samples/showcase/?r=7726

它在 web.xml中定义一个过滤器使用 _escaped_fragment _ 标记将URL重定向到HTML单元的输出。

It defines a filter in the web.xml to redirect URLs with the _escaped_fragment_ token to the output of HTML Unit.
