使用 Android Web 服务器在文件夹中提供文件

Serve files in folder with an Android Web Server

我想提供本地文件夹的文件(例如,.html 和 .css 文件)以重新创建 "real" 本地网站的通常行为.

这里有两个应用程序示例,它们可以按照我希望的方式运行:Tiny Web Server Free and kWS - Android Web Server

我用 Google 搜索了很多,但我找不到任何东西...

我尝试使用 NanoHttpd,但我们似乎无法设置根目录或主目录,我们只能通过 returning a [=] 来 return 一些 http 代码11=] 对象与 serve() 方法。那不是我想要的。

我希望能够设置一个根目录,例如 sdcard/www/,其中包含 sdcard/www/img/ 子文件夹中的图像的 index.html...

另外,我找到了this answer,但这不是我想要的。它包括 return 使用 serve() 方法将 .html 文件的内容写入 Response 对象。

我怎样才能做我想做的事?

我已经通过以下代码成功地提供了一个文件夹... 这是我 Android Web 服务器 class 中的响应方法 -->

public Response serve(IHTTPSession session) {
    String uri=session.getUri();
    String msg = "<html><body><h1>Hello server</h1>\n";

    File [] arrayfile;

    int i=0;

    try{
        session.parseBody(new HashMap<String, String>());
    }catch (ResponseException | IOException r){
        r.printStackTrace();
    }


    Map<String, String> parms = session.getParms();
    if (parms.get("username") == null) {
        msg += "<form action='?' method='get'>\n  <p>Your name: <input type='text' name='username'></p>\n" + "</form>\n";
    } else {
        msg += "<p>Hello, " + parms.get("username") + "!</p>";
    }
    msg += "<br><br><a href='/Open_rap'>Open Image of Lionel Messi</a><br><br>";

如你所见, uri.contains(.)
这部分代码是我使用 root 文件对象实现文件夹的地方, file input stream 我的文件保存在我的 android 设备 /www/files 的内部存储器中 如果您有任何问题,请联系我。

您可以使用google/webview-local-server

我正在使用 nanohttpd 来提供文件,这是我使用的工作代码

@Override
public Response serve(IHTTPSession session) {
    String msg = "<html><body><h1>Hello server</h1></body></html>\n";
    String msgUnauthorized = "<html><body><h1>Unauthorized</h1></body></html>\n";
    Method method = session.getMethod();
    String uri = session.getUri();
    Map<String, String> files = new HashMap<>();

    String Endpoint = session.getUri();
    if (Endpoint.equals("/")) {

        String answer = "";
        try {
            // Open file from SD Card
            File root = Environment.getExternalStorageDirectory().getAbsoluteFile();
            FileReader index = new FileReader(root +
                    "/www/openrap/index.html");
            BufferedReader reader = new BufferedReader(index);
            String line = "";
            while ((line = reader.readLine()) != null) {
                answer += line;
            }
            reader.close();
        } catch (IOException ioe) {
            Log.w("Httpd", ioe.toString());
        }
