Usage

The best tutorial is sample, recommended download preview.

Create Server

AndServer andServer = new AndServer.Build()
    ...
    .build();

// Create server.
Server mServer = andServer.createServer();
...

// Start server.
mServer.start();
...

// Stop server.
mServer.stop();
...

// Server is running ?
boolean running = mServer.isRunning();

Port & Response Timeout

AndServer andServer = new AndServer.Build()
    .port(8080) // Default 8080, can be any port.
    .timeout(10 * 1000) // But for MS, the default is 10 * 1000 ms.
    ...
    .build();
...

Website deployment

The deployment website is through the Website interface, you can implement it. AndServer provides two default implementations:

Through their registered website, the default home page is：

http://ip:port/
http://ip:port/youPath
http://ip:port/youPath/index.html

Register the website

Website website = new AssetsWebsite(AssetManager, youPath);
// or
Website website = new StorageWebsite(youPath);

AndServer andServer = new AndServer.Build()
    ...
    .website(website);
    .build();

AssetsWebsite usage

Use it when your static site content is placed under assets.

The way to use is:

AssetManager mAssetManager = getAssets(); //AssetManager can not be closed.

Website website = new AssetsWebsite(mAssetManager, youPath);

If the website root directory under the assets, then the incoming "", such as:

Website website = new AssetsWebsite(mAssetManager, "");

Then your default home page is:
http://ip:port
http://ip:port/index.html

Other page addresses is:
http://ip:port/login.html
http://ip:port/error.html

For example:

http://192.168.1.12:8080/index.html  
http://192.168.1.12:8080/login.html

If the root directory of the site is in the subdirectory of assets, then the relative path to the directory, such as the site in the assets web directory, such as:

Website website = new AssetsWebsite(mAssetManager, "web");

Then your default home page is:
http://ip:port
http://ip:port/web
http://ip:port/web/index.html

Other page addresses is:
http://ip:port/web/login.html
http://ip:port/web/error.html

For example:

http://192.168.1.12:8080
http://192.168.1.12:8080/web
http://192.168.1.12:8080/web/index.html
http://192.168.1.12:8080/web/error.html  
http://192.168.1.12:8080/web/login.html

StorageWebsite usage

Use it when your static site is on a storage device, such as your site under SD card.

The way to use is:

Website website = new StorageWebsite(youPath);

It is simple, the absolute path into your website root directory on it, for example, your site in the SD card under the www directory:

File file = new File(Environment.getExternalStorageDirectory(), "www");
String websiteDirectory = file.getAbsolutePath();

Website website = new StorageWebsite(websiteDirectory);

Access address and AssetsWebsite the same reason.

Http API

Http API is through the RequestHandler interface registration, it is a java interface, it's the same as JavaEE's Servlet.

You need to implement it, and then registered to AndServer on it, such as:

public class RequestLoginHandler implements RequestHandler {

    @Override
    public void handle(HttpRequest req, HttpResponse res, HttpContext con) {
        Map<String, String> params = HttpRequestParser.parse(request);

        // Request params.        
        String userName = params.get("username");
        String password = params.get("password");

        if ("123".equals(userName) && "123".equals(password)) {
            StringEntity stringEntity = new StringEntity("Login Succeed", "utf-8");
            response.setEntity(stringEntity);
        } else {
            StringEntity stringEntity = new StringEntity("Login Failed", "utf-8");
            response.setEntity(stringEntity);
        }
    }
}

And then register it in AndServer:

AndServer andServer = new AndServer.Build()
    ...
    .registerHandler("login", new RequestLoginHandler())
    .build();

Now you can get a unique access address: http://ip:port/login, for example:

http://192.168.1.12:8080/login?username=123&password=123

For example of file download and file upload, please refer to sample.

Html submit form

In the action of the Html's form fill in you register RequestHandler key, and then you can get the form parameters in the handle(HttpRequest, HttpResponse, HttpContext) method of the RequestHandler.

Such as the top of the Login RequestHandler:

<form id="form1" method="post" action="login">
...
</form>

Listens on server status

private Server.Listener mListener = new Server.Listener() {
    @Override
    public void onStarted() {
        // The server started successfully.
    }

    @Override
    public void onStopped() {
        // The server stops.
    }

    @Override
    public void onError(Exception e) {
        // There was an error when starting the server, usually the port was occupied.
    }
};

AndServer andServer = new AndServer.Build()
    ...
    .listener(mListener)
    .build();
