Java Android AssetServer扩展NanoHTTPD
我正在开发一个扩展NanoHTTPD的AssetServer,以便访问基于文件的页面无法使用的Javascript功能 这是我目前掌握的代码:Java Android AssetServer扩展NanoHTTPD,java,android,cordova,nanohttpd,Java,Android,Cordova,Nanohttpd,我正在开发一个扩展NanoHTTPD的AssetServer,以便访问基于文件的页面无法使用的Javascript功能 这是我目前掌握的代码: class AssetServer extends NanoHTTPD{ private Activity activity; public AssetServer(int port, Activity activity) { super(port); this.activity = activ
class AssetServer extends NanoHTTPD{
private Activity activity;
public AssetServer(int port, Activity activity)
{

@Override
public Response serve(IHTTPSession session){
String mime = "text/plain";
InputStream is = null;
String path = "www" + session.getUri();
System.out.println("nanohttpd: serving " + path);
String response = null;
try{
is = activity.getAssets().open(path);
int size = is.available();
byte[] buffer = new byte[size];
is.read(buffer);
is.close();
response = new String(buffer);
}catch(IOException ioe){
System.err.println("nanohttpd: error: " + ioe);
}
Response res = new Response(Response.Status.OK, mime, response);
return res;
}
}
在我的手机上运行android应用程序时,logcat输出表明页面接收到页面请求的部分(但不是全部)文件。在我的loadUrl调用中有五秒钟的延迟,以便在服务页面之前给服务器一些时间预热
以下是logcat输出:

有人知道我做错了什么吗?
提前谢谢 非常适合这种情况

试一试{

我验证了我确实从资产中获得了一个字符串。
