我正在使用 Phonegap-CLI (v5.4.0) 和 Phonegap-developer-app（Android 和 iOS，都是最新的）创建一个简单的跨平台应用程序。在我的应用程序中，我试图调用我实现的 REST 接口，我使用 jQuery AJAX 来执行此操作。不幸的是，这些电话似乎不起作用，我在控制台中看不到任何来电。（REST-Interface 在我的机器上本地运行。）但是，我知道我的 REST-Interface 工作正常，因为我可以使用 IntelliJ-testing-tool 正确调用 REST-Interface。
我的index.html样子是这样的：
<html>
<head>
<meta http-equiv="Content-Security-Policy" content="default-src *; style-src 'self' 'unsafe-inline'; script-src 'self' 'unsafe-inline' 'unsafe-eval'">
<meta charset="utf-8" />
<meta name="format-detection" content="telephone=no" />
<meta name="msapplication-tap-highlight" content="no" />

$.ajax({

error: function(){

}
});
});
}, true);
/*app.initialize();*/
</script>
</body>
</html>
这就是我的config.xml样子。这是创建项目时生成的默认文件：
<?xml version='1.0' encoding='utf-8'?>
<widget id="my.app.identifier" version="1.0.0" xmlns="http://www.w3.org/ns/widgets" xmlns:gap="http://phonegap.com/ns/1.0">
<name>hibou</name>
<description>
Hello World sample application that responds to the deviceready event.

通过上述设置，我总是得到“开始”和“不起作用”的警报。但是由于当我将 AJAX 调用包含到一些非 phonegap HTML 文档中并且来自我的应用程序的调用甚至没有到达我的 REST 接口时，AJAX 调用工作正常，我假设它可能是一些问题phonegap-whitelist-plugin，但正如您所见，它已经包含在 中，config.xml并且该<access origin="*" />标签也应该允许所有网络连接。我已经检查了 Security-Policy 元标记，但据我所知，这也不应该导致这个问题。毕竟，我不知道是什么导致了这个错误，所以我真的很感激一些帮助或提示我在这里可能会错过什么......非常感谢！
