我正在制作一个需要使用远程http服务器的应用程序。在浏览器中我对ajax / inAppBrowser / iframe没有任何问题，但是当在Android中构建和运行它时它不再起作用。
我使用了远程chrome调试器，只是注意到所有请求都没有从缓存中找到404，所以我猜测应用程序没有权利在网上发出请求。我搜索了一个解决方案，但我无法弄清楚它来自哪里。
这是我的config.xml：

我试图从开始再次开始，但这是最简单的。有些线路可能没用，但我尝试了不同的解决方案来解决我的问题。

Some notes:
* gap: is required only on iOS (when using UIWebView) and is needed for JS->native communication
* https://ssl.gstatic.com is required only on Android and is needed for TalkBack to function properly
* Disables use of inline scripts in order to mitigate risk of XSS vulnerabilities. To change this:
* Enable inline JS: add 'unsafe-inline' to default-src
