Failed to get the input stream of the raw socket about nv-websocket-client HOT 17 CLOSED

Could you tell me the URL? I'll try to access it.

from nv-websocket-client.

You see the error message "Failed to get the input stream of the raw socket" when getInputStream() of java.net.Socket failed. See the implementation of openInputStream(Socket) in WebSocket.java.

The WebSocketException instance you receive in onError method contains the IOException instance that getInputStream() threw. Please check what the exception is saying. LIke this:

@Override
public void onError(WebSocket websocket, WebSocketException cause) throws Exception
{
    // Print the stack trace of the IOException.
    cause.getCause().printStackTrace();
}

Hi TakahikoKawasaki,I also encountered this problem and this is my code:

public void initWs() throws IOException, WebSocketException,
        URISyntaxException, NoSuchAlgorithmException {
    String token = "0EE86165533E49841A063472B8639223|8baaf6b1385145545c4ec4c4c151e0aa|1444295714";
    token = URLEncoder.encode(token, "UTF-8");
    String exampleUri;
    exampleUri = "wss://yggdrasil.bz-inc.com:11506/im?token=" + token;
    // exampleUri = "wss://echo.websocket.org";
    // exampleUri = "ws://echo.websocket.org";
    WebSocketFactory webSocketFactory = new WebSocketFactory();
    webSocketFactory
            .setSSLContext(
                    SSLContext.getInstance("Default"))
            .setSSLSocketFactory(
                    (SSLSocketFactory) SSLSocketFactory.getDefault());
    ws = webSocketFactory
            .setConnectionTimeout(TIMEOUT)
            .createSocket(exampleUri)
            .setPingInterval(20 * 1000)
            .addListener(webSocketAdapter);
    ws.connect();
}

from nv-websocket-client.

Please read the JavaDoc of WebSocketFactory.createSocket(URI) for details about SSL configuration. Also, see the discussion in #6. In short, if you call setSSLContext(), calling setSSLSocketFactory() has no meaning. Moreover, if you want to use the default settings, you don't have to call setSSL*() functions at all.

Please check whether SSLContext.getInstance("Default") returns a valid SSLContext instance. I'm not sure SSLContext.getInstance(String) accepts "Default" as a valid value.

I released a new version 1.11. Please use it to see what an additional error message says after "Failed to get the input stream of the raw socket".

The following is the CHANGES made in version 1.11.

1.11 (2015-10-12)

• Changed some error messages of WebSocketException.
  (Appended cause.getMessage() in cases where a cause is available.)

from nv-websocket-client.

That is ok, thank you so much!

from nv-websocket-client.

yeah , now I can connect our server by version 1.11. but some urls contain '|' can`t be created URI directly,so I changed your code. My connecting code:

from nv-websocket-client.

Oh, sorry. It's my bug. I fixed the bug and released a new version 1.12. Please try the new version.

1.12 (2015-10-12)

• Fixed a bug in WebSocketFactory. getRawPath() and getRawQuery()
  should be used instead of getPath() and getQuery().

from nv-websocket-client.

That is right! It is so easy for me to connect our server .We`re using your library in our IM system and it seems very good.Of course ,If there are some other troubles bother me, I will come back to ask for your help immediately.

I am also getting similar error. Below is error, Can you please help

Below is my code. Please let me know if something is wrong

The stack trace says "Connection closed by peer". You may be able to find a hint in the log messages on the server side.

In addition, what is BB-GW-01 protocol? nv-websocket-client does not support the protocol.

from nv-websocket-client.

Thanks for your response.
BB-GW-01 is subprotocol in websocket.

I am attaching screen shot of wireshark if you can make out what can be problem . 192.168.50.104 is my mobile IP and 192.168.50.1 is Server IP. Server is written using libwebsocket C library and we are able to connect using iPhone to the same server using wss.

I am able to connect on ws but not on wss using nvwebsocket client library

from nv-websocket-client.

Also sometime I get this in wireshark but both time I get same stack trace

from nv-websocket-client.

I'm afraid that the root cause is in the implementation of TLS. What if you give "TLSv1.2" to NaiveSSLContext.getInstance(String) instead of "TLS"?

FYI: javax.net.ssl.SSLContext.getInstance(String)

from nv-websocket-client.

It make no difference whether i give TLSv1.2 or TLS. In my scenario I am connecting to an embedded Linux based device which provide webscoket server. It had custom certificate hence I am ignoring them using NavieContext. Now there are two scenario

1. When Embedded device and Android both are in corporate network , I am able to connect to websocket server
2. When Android directly connect to embedded device on device's wifi access point then it give SSL_handshake error.
   I am attaching snapshot of wireshark log for both cases. In case you want actual wireshark to make nay comment then let me know.

Hi,
In continuation to my earlier issue of not albe to connect to after some more research I had found out the reason. In SSL connection android SDK an unnecessary DNS lookup which causes delay. Please see link http://stackoverflow.com/questions/4737019/tls-connection-using-sslsocket-is-slow-in-android-os

In my case it was taking around 30 seconds. After increasing the timeout at I was successfully able to connect the server. My question is how I can do same in this websocket library or override some function of library. Any input on this will be of great help.

from nv-websocket-client.

Now I had get solution to the above problem. When hostname is IP address InetSocketAddress constructor fill addr field and make HostName file null. During actual SSL connection it tries to get hostname via reverse DNS lookup. As I only want to create tls connection via IP so I injected hostname into InetSocketAddress I modified toInetSocketAddress() function of Address.java

InetSocketAddress toInetSocketAddress()
{
try {
InetAddress addr = InetAddress.getByName(mHost);
Log.d("InetsocketAddress call","before call");
injectHostname(addr,mHost);
return new InetSocketAddress(addr, mPort);

    }
    catch ( Exception e)
    {
        Log.d("InetsocketAddress fail", e.getMessage());

        return new InetSocketAddress(mHost, mPort);
    }

}

private void injectHostname(InetAddress address, String host) {
try {
Field field = InetAddress.class.getDeclaredField("hostName");
field.setAccessible(true);
field.set(address, host);
} catch (Exception ignored) {
}
}
