这是代码段的一部分获取应用程序的本地路径并在iframe中加载路径：

  var appLocalUrl = cordova.file.dataDirectory + AppId +/index.html; 
 iframe [0] .contentWindow.location.replace（appLocalUrl）;

应用程序下载到本地路径
，但是当我们尝试在iframe结束时错误消息：

有任何帮助吗？

解决方案

所以我已经努力了很多与此相关。
最新的iOS使用WKWebView。它似乎将本地文件视为来自远程服务器，即使它们在应用程序本身，并且此类请求被阻止。参考

以下解决方案适用于我：

添加Corodova文件插件。 p>

cordova插件add cordova-plugin-file

p>将本地文件路径更改为：

cdvfile：//localhost/bundle/www/you_folder_name/file_name.mp3

This is the part of the code snippet to get the local path of the app and loading the path in an iframe:

var appLocalUrl = cordova.file.dataDirectory + AppId + "/index.html";
iframe[0].contentWindow.location.replace(appLocalUrl);

The app is downloaded to local pathbut when we try to launch this in iframe ended up with error message:

Any help on this?

解决方案

So I have already struggled a lot related to this.Latest iOS uses WKWebView. It appears to treat local files as if they came from a remote server, even though they're in the app itself, and such requests are blocked. Reference Source

The following solution worked for me:

Add the Corodova file plugin.
cordova plugin add cordova-plugin-file
Change the local file path to this:
cdvfile://localhost/bundle/www/you_folder_name/file_name.mp3
