使用Java在Google App Engine中读取请求参数 [英] Reading request parameters in Google App Engine with Java
问题描述
当您使用Google Web Toolkit和Google App Engine创建新项目时,我正在修改Eclipse创建的默认项目。它是GreetingService示例项目。
I'm modifying the default project that Eclipse creates when you create a new project with Google Web Toolkit and Google App Engine. It is the GreetingService sample project.
如何在客户端的.java文件中读取请求参数?
How can I read a request parameter in the client's .java file?
例如,当前的URL是 http://127.0.0.1:8887/MyProj.html?gwt.codesvr=127.0.0.1&foo=bar
,我想使用像 request.getParameter(foo)==bar
。
For example, the current URL is http://127.0.0.1:8887/MyProj.html?gwt.codesvr=127.0.0.1&foo=bar
and I want to use something like request.getParameter("foo") == "bar"
.
之类的东西,我看到文档中提到了Python的请求类,但我不能找不到Java的等价物。它被列在 google.appengine.ext.webapp
包中,但如果我尝试将它导入到我的.java文件(使用 com)。 前缀),它表示它无法解析
ext
部分。
I saw that the documentation mentions the Request class for Python, but I couldn't find the equivalent for Java. It's listed as being in the google.appengine.ext.webapp
package, but if I try importing that into my .java file (with a com.
prefix), it says that it can't resolve the ext
part.
推荐答案
我可以使用 Window.Location via :
<$ 4515148>这个答案:
I was able to get it to work using Window.Location via this answer:
import com.google.gwt.user.client.Window;
// ...
Window.Location.getParameter("foo") // == "bar"
注意:
Note that:
位置是一个非常简单的包装,所以并非所有的浏览器怪癖都不会被用户隐藏。
Location is a very simple wrapper, so not all browser quirks are hidden from the user.
