window.resolveLocalFileSystemURI is not a function
提问by Khalid
I created a web application that I need to convert to a mobile application, now all I have is html5/js/css files which means I don't have any www foder no platforms folder, not a cordova project ... I started first to build the app using cordova command lines, but I couldn't, I found many problems on that, I used then https://build.phonegap.com/, and it works fine for me. In order to read the file, I have tried this code :
我创建了一个需要转换为移动应用程序的 Web 应用程序，现在我只有 html5/js/css 文件，这意味着我没有任何 www foder noplatforms 文件夹，而不是cordova 项目......我首先开始使用cordova命令行构建应用程序，但我不能，我发现了很多问题，然后我使用了https://build.phonegap.com/，它对我来说很好用。为了读取文件，我尝试了以下代码：
window.resolveLocalFileSystemURI("file:///android_asset/www/data/User.xml", function () {
alert("Success");
}, function () {
alert(" error ");
});

You need to install a plugin for this to work.
你需要安装一个插件才能工作。
Basically, run "cordova plugin add org.apache.cordova.file" at your application's root directory.
基本上，在应用程序的根目录中运行“cordova plugin add org.apache.cordova.file”。
For detailed instructions see here, under "Accessing the Feature": http://docs.phonegap.com/en/edge/cordova_file_file.md.html#LocalFileSystem

The correct way to add this plugin is now with this command in your project root:
添加此插件的正确方法现在是在项目根目录中使用以下命令：
cordova plugin add cordova-plugin-file
This is a core cordova plugin. Documentation found here on npm
这是一个核心的cordova插件。在 npm 上找到的文档
