QUESTION
I am able to communicate with socketTest with the same ip address, but within UNITY I get an error message
SocketException: The requested address is not valid in the context.
I tried
...ANSWER
Answered 2021-Dec-01 at 08:03This is not really specific to Unity
but rather c#
in general.
Socket.Bind
is for binding the socket to a specific local endpoint! Such as for example you want to limit the socket to a specific local network adapter / address (by default it will use any/all) or a specific local port (by default it will pick any free local port)
Use the
Bind
method if you need to use a specific local endpoint. You must callBind
before you can call theListen
method. You do not need to callBind
before using theConnect
method unless you need to use a specific local endpoint.
Usually you use Bind
mostly for the server side for listening and waiting for incoming connections or for connectionless protocols like UDP
.
You most probably simply want to rather use Socket.Connect
for establishing a connection to a remote server.
When using Connect
without Bind
then it will simply pick the network adapter / address it finds to be the best fit for reaching the given host address and picks the next free local port.
However, in general I would recommend to rather use TcpClient
instead of composing and configuring the Socket
"manually" (except the use case requires it).

QUESTION
ANSWER
Answered 2021-Oct-01 at 06:28This Socket Test app (if that's the one you're using) creates a generic TCP server, not a webSocket server. A webSocket client MUST connect to a webSocket server. It needs something that speaks the webSocket connection protocol in order to have a successful connection and when you point it at a plain TCP server, it will send it's initial connection request, but not receive the response it expects (the first stage of the webSocket connection protocol) and thus never connect successfully.
FYI, you can see how a basic webSocket server works here on MDN and that will show you a sample of the webSocket connection protocol that a webSocket client is expecting (that your generic TCP server is not providing).
QUESTION
I'm building an app with a chat feature using express.js, react.js and socket.io. Here is a minimal version with the bug reproduced on Github.
The problem is the server's socket.on()
always fires twice, for no reason that is apparent to me.
As far as I can tell the client only ever sends a single .emit
, but the server's .on
always fires twice (and I'm fairly certain that event handler isn't bound twice), regardless of how many clients are connected, or indeed how I've refactored the code.
The sending client's form (input + button) appends the message to its local messages list and then dispatches MESSAGE_NEW
to the reducer.
Here's first the Socket.js
file.

Why don't you try to call the event from the custom functions instead of init method. You can do as follows.

Hello i'm trying to execute a socket client in Java, but the client still reading the data and don't proceed with the program execution. Any ideas?
Here's the code:
...ANSWER
Answered 2020-Apr-17 at 19:41DataInputStream.readUTF
expects a uniquely weird message format. The first two bytes it reads are interpreted as the length of the string to read, in a big endian binary format. This is then followed by a weird non-standard text encoding similar to but incompatible with UTF-8. Most likely you should not be using DataInputStream.readUTF
to read data in a program, unless you used its counterpart DataOutputStream.writeUTF
to write it in the first place.
Based on your comments it sounds like your communication protocol is based on lines of text. To read lines of text, you can use for example the BufferedReader
class.

I try to create a Socket messager between a Java Client and Python Server. It works to send a message ("Testdata") from client to server and print it out. But after input and send a message from server to client, I get no output from client. The client 'freezes' and must be terminated.
What is the problem with my client input?
