如何获取Phonegap应用以在Android上接收变量？

在Stack OVerflow社区的帮助下,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,它就会直接打开我的应用程序.换句话说,我有我的< intent-filter>在我的AndroidManifest.xml中正确配置.

到目前为止一切都很好,但还有最后一步,我仍然在努力,这是让我的Phonegap构建的应用程序拿起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>

点击该链接可打开我的应用.确切地说,当单击它时,会弹出一个对话框,询问用户是否要使用浏览器或我的应用程序打开,这很酷.

无论如何,重点是,如果他们使用我的应用程序打开我的应用程序,它将打开默认的欢迎屏幕.但是,所需的行为是应用程序打开特定页面,confirm.html,并且有两个字段填充了URL,验证和用户名中的变量.

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：我真的很想强调,这是绝对清楚的,这是一个Phonegap构建,这意味着该应用程序使用HTML和Javascript,而不是原生的Android代码.谢谢你的理解.

解决方法

如果您正在使用WebIntent(我假设您这样做了吗？),您可以这样做：

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.在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.

最新版本的插件的问题似乎在webintent.js文件中.

我更改了几行代码来修复文件中发生的错误.

        ((DroidGap)this.cordova.getActivity()).sendBroadcast(intent);
    }
}

和html文件.

<!DOCTYPE html>

    <script type="text/javascript" charset="utf-8" src="cordova.js"></script>

    // Wait for device API libraries to load
    //
    function onLoad() {
        alert("onLoad");
        document.addEventListener("deviceready",onDeviceReady,false);
    }
 
    // device APIs are available
    //
    function onDeviceReady() {
        alert("onDeviceReady");
        window.plugins.webintent.getUri(function(url) {
            if(url !== "") {
                // url is the url the intent was launched with
                document.querySelector("#test").innerHTML = "URL was "+url;
            }
        });
    }
 
    </script>
  </head>
  <body onload="onLoad()">
<h1>Test</h1>
 
<div id="test"></div>
  </body>
</html>

我用这段代码测试了它,我正确地收到了一个URL.如果你想我可以发给你整个项目(给我发电子邮件).希望这可以帮助.
