Socket connectivity issue

[Ramkesh9]

Hi, error :- com.neovisionaries.ws.client.WebSocketException: The status line of the opening handshake response is empty. i am getting problems while connecting with socket from my android app, can any one give me complete source code or help me with how to connect mobile app with my socket server . i am using this url -> " WebSocket ws = factory.cr eateSocket("ws://service.arunlogistics.com:8001", 5000);" it needs to headers -> ws.addHeader("token", "7d2ce13ef67e34468b6b5d201008ec8d1c836182"); -> ws.addHeader("vehicle", "PB10EX1060");

--> yesterday it was connected once by chance , but not reconnected again, till now

i also attached my source code ,so you can see my code for where i am lacking , its urgent, so any help will be appreciable . socketconnection.txt

ws.addHeader("token", "7d2ce13ef67e34468b6b5d201008ec8d1c836182");
ws.addHeader("vehicle", "PB10EX1060");

will generate HTTP headers like below

token: 7d2ce13ef67e34468b6b5d201008ec8d1c836182
vehicle: PB10EX1060

Is this really what you want to do?

The name of token implies that the WebSocket endpoint is protected by a security token such as OAuth 2.0 access token. Why don't you ask the implementer of the WebSocket endpoint about how the endpoint is protected?

i need to pass this header for auth and get connected with websocket , so what should i do?

[TakahikoKawasaki]

For example, in normal cases, OAuth 2.0 access tokens are presented to APIs as follows as defined in RFC 6750, 2.1. Authorization Request Header Field.

Authorization: Bearer {access-token}

I don't know how your WebSocket endpoint is protected, however, the following HTTP header:

token: 7d2ce13ef67e34468b6b5d201008ec8d1c836182

looks abnormal. Therefore, it is worth checking again how to pass the token parameter to the WebSocket endpoint.

And, just FYI.

Basic Authentication is another often-used way. If an API is protected by Basic Authentication, you have to pass:

Authorization: Basic {credentials}

{credentials} above is a Base64 representation of id:password.

can you assit me some for header sennding ?

[TakahikoKawasaki]

At this moment, I cannot help you any more because I don't know the specification of the WebSocket endpoint.

First, investigate how the WebSocket endpoint is protected. Second, tell me the specification. Then, I'll be able to explain how to use nv-websocket-client APIs to comply with the specification.
