将 Google Analytics 集成到 GWT 应用程序中

这应该是完全简单的，但无论我尝试什么，我都无法让它工作。我正在尝试将 Google Analytics 与 GWT 应用程序一起使用。据我了解，有两种方法可以做到这一点：

第一种是同步的，通过在的末尾插入跟踪代码。部分 HTML 页面，然后调用此方法：

public static native void recordAnalyticsHit(String pageName) /*-{
    pageTracker._trackPageview(pageName);
}-*/;

第二个是异步的，通过在之后插入跟踪代码标记，然后调用此方法：

public static native void recordAnalyticsHit(String pageName) /*-{
    _gaq.push(['_trackPageview(' + pageName + ')']);
}-*/;

但是，当运行每个方法时，我在托管模式下遇到此异常：

[ERROR] [myproject] Uncaught exception escaped
com.google.gwt.core.client.JavaScriptException: (ReferenceError): pageTracker is not defined

[ERROR] [myproject] Uncaught exception escaped
com.google.gwt.core.client.JavaScriptException: (ReferenceError): _gaq is not defined

在 Firebug 中观察站点时，我看到 ga.js 已加载，但仅此而已。

有人让 Analytics 与 GWT 一起使用吗？另外，_gaq 是否接受页面名称作为 trackPageview 参数，因为我见过的所有示例都使用此调用：（

_gaq.push(['_trackPageview()']);

当然，这对我也不起作用。）

This should be totally simple but I can't get it working no matter what I try. I'm trying to use Google Analytics with GWT application. From what I understood, there are two way to do it:

First is synchronous, by inserting tracking code at the end of <head> section HTML page and then calling this method:

public static native void recordAnalyticsHit(String pageName) /*-{
    pageTracker._trackPageview(pageName);
}-*/;

Second is asynchronous, by inserting tracking code just after <body> tag and then calling this method:

public static native void recordAnalyticsHit(String pageName) /*-{
    _gaq.push(['_trackPageview(' + pageName + ')']);
}-*/;

When running each of those methods, however, I get this exceptions in hosted mode:

[ERROR] [myproject] Uncaught exception escaped
com.google.gwt.core.client.JavaScriptException: (ReferenceError): pageTracker is not defined

[ERROR] [myproject] Uncaught exception escaped
com.google.gwt.core.client.JavaScriptException: (ReferenceError): _gaq is not defined

When observing site in Firebug, I see that ga.js gets loaded, but that's about it.

Did anyone get Analytics working with GWT? Also, does _gaq accept page name as trackPageview parameter, since all the examples I've seen use this call:

_gaq.push(['_trackPageview()']);

(Of course, that also doesn't work for me.)

这只是一种猜测，但您可能需要通过 JSNI 中的 $wnd 引用主机页（包含 Google Analytics JS 代码的主机页），如下所示：

public static native void recordAnalyticsHit(String pageName) /*-{
    $wnd.pageTracker._trackPageview(pageName);
}-*/;

JSNI 代码（以及一般情况下，GWT 代码）在 iframe 中运行以保持命名空间干净，这就是为什么您需要对主窗口的 $wnd 引用。

This is just a guess, but you probably need to reference the host page (the one where the Google Analytics JS code has been included) via $wnd in the JSNI, like this:

public static native void recordAnalyticsHit(String pageName) /*-{
    $wnd.pageTracker._trackPageview(pageName);
}-*/;

JSNI code (and in general, GWT code) is run in a iframe to keep the namespace clean, that's why you need the $wnd reference to the main window.
