在 Stack Overflow 社区的大力帮助下，我现在已经成功设置了我的 Android 应用程序，这样当点击电子邮件中的链接时，它会直接打开我的应用程序。换句话说，我<intent-filter>的AndroidManifest.xml配置正确。

到目前为止一切都很好，但我仍在努力完成最后一步，即让我的 Phonegap 构建的应用程序获取并使用我从电子邮件中的 URL 传递给它的变量。

电子邮件中的链接如下所示：

<a target="_blank" href="https://mysite.com/confirmation.html?verification=XXXXXXXXX&username=larry">Complete verification with MYAPP</a>

点击链接打开我的应用程序。准确地说，当点击它时，会弹出一个对话框，询问用户是要使用浏览器还是我的应用程序打开，这很酷。

无论如何，关键是如果他们使用我的应用程序打开我的应用程序，它将打开到默认的欢迎屏幕。但是，所需的行为是应用程序打开到特定页面，confirmation.html并且有两个字段填充来自 URL 的变量，验证和用户名。

如何让我的Phonegap应用程序在正确的页面上启动并使用 URL 中的变量？

重要提示：我真的想强调一下，绝对清楚，这是一个 Phonegap 构建，这意味着该应用程序使用 HTML 和 Javascript，而不是原生 Android 代码。感谢你的理解。

如果您正在使用WebIntent（我假设您这样做？），您可以简单地执行以下操作：

window.plugins.webintent.getUri(function(url) {
        if(url !== "") {
            // url is the url the intent was launched with
            document.querySelector("#tag").innerHTML = "URL = " + url;
        }
    });

编辑：

好的，所以我设法让插件在 PhoneGap 2.9.0 上运行。

但是，我必须澄清一些事情。

首先，您说某些方法已被弃用，但弃用并不意味着这些方法不起作用。github 上列出的（旧）插件工作正常，但我确实设法让它与 CordovaPlugin 一起工作。

插件最新版本的问题似乎在 webintent.js 文件中。

我更改了几行代码来修复文件内部发生的错误。

我用这段代码测试了它，我正确地收到了一个 URL。如果你愿意，我可以把整个项目发给你（给我发电子邮件）。希望这可以帮助。
