将数据从Java客户端发送到Node.js服务器

Question

So i send a normal string from a java client to the server and the server successfully recieves it. The problem is that the recieved data is more than just the string which i originally sent.

i send the data in java with a DataOutputStream - > writeUTF("Welcome...");

See console output

without using JSON.stringify()

nodeJS client

connection --> 127.0.0.1
Data arrived type = string
Data = Welcome...
end
Disconnect --> 127.0.0.1

java client

connection --> 127.0.0.1
Data arrived type = string
Data = 
Welcome...
end
Disconnect --> 127.0.0.1

with JSON.stringify()

nodeJS client

connection --> 127.0.0.1
Data arrived type = string
Data = "Welcome..."
end
Disconnect --> 127.0.0.1

java client

connection --> 127.0.0.1
Data arrived type = string
Data = "\u0000\nWelcome..."
end
Disconnect --> 127.0.0.1

so i wonder how i can get rid of the stuff in front of my message when i recieve it from the java client? A normal replace() makes no sense because it varies.

Answer 1

The problem may be in the java side. Why are you using DataOutputStream? Try using the OutputStreamWriter class which is better suited for sending text.
