如何通过PhoneGap调用C#的WebService？

使用PhoneGAP调用webservice跟原生sdk方式不太一样，你需要定义一个plugin然后调用C#的webservice

下面是我的一个程序里调用的一个人脸识别的例子 你可以参考一下 不明白可以Q我 550876005

plugin 类

在res/xml/config.xml中添加这个plugin
<feature name="FacePlugin">
      <param name="android-package" value="com.sdses.plugin.FacePlugin" />
    </feature>


在html中调用如下   

function RequestWebService(base64, userId) {
 cordova.exec(successFunction, failFunction, "FacePlugin","checkFaceEntry",[{"base64": base64, "userId": userId}]);
 }
