Question

我在我的应用程序Restlet服务器中，如果我在浏览器中打开服务器地址，那么服务器应返回某个文件夹中的文件列表，如果用户单击该文件，则应下载该文件。

我看了这个tutorial。第6部分提供静态文件。这是代码：

public static final String ROOT_URI = "file:///c:/restlet/docs/api/";

[...]

// Create a component
Component component = new Component();
component.getServers().add(Protocol.HTTP, 8182);
component.getClients().add(Protocol.FILE);

// Create an application
Application application = new Application() {
    @Override
    public Restlet createInboundRoot() {
            return new Directory(getContext(), ROOT_URI);
    }
};

// Attach the application to the component and start it
component.getDefaultHost().attach(application);
component.start();

但是如果我在URI中使用例如file:///sdcard/，那么如果我在浏览器中打开地址，我会得到

Not Found

The server has not found anything matching the request URI

出了什么问题？如何使用Restlet返回文件列表？

我的解决方案：

    mWebServerComponent = new Component();
    mWebServerComponent.getClients().add(Protocol.FILE);
    mWebServerComponent.getServers().add(Protocol.HTTP, 8182);
    mWebServerComponent.getDefaultHost().attach(new FileApplication());
    try {
        mWebServerComponent.start();
    } catch (Exception e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

FileApplication类：

public class FileApplication extends Application {

// for example: public static final String ROOT_URI =
// "file:///C:/restlet-jee-2.0.6/docs/api/";
@Override
public synchronized Restlet createInboundRoot() {

    String ROOT_URI = "file:///"
            + Environment.getExternalStorageDirectory() + "/";

    Directory directory = new Directory(getContext(),
            LocalReference.localizePath(ROOT_URI));
    directory.setListingAllowed(true);
    Router router = new Router(getContext());

    router.attach("/files", directory);

    return router;
}
}
