client-server

问题 I have RestFul web service method developed using jersey-bundle(1.1.1,1.17.1) and deployed to weblogic server 10.3.4.0. I get duplicate calls for some of the call when client made. I get my rest service getting called twice when it actually made one. I have capture some of the network logs using wireshark and found that it happens whenever stats [RST, ACK] sent by the server. What could be the reason for server sending back [RST] for some of the calls from client? 回答1: I've found this report:

问题 I am trying to conceptually work through a model for a client-server socket application I am writing in c# (both client and server). My server will need to handle many clients at once, and preferably multiple requests from a client at once. I have worked out a container for my communication where I will send a fixed length header at the beginning of each message which will contain (among other things) the length of the message. I have some experience with socket programming in c#, so I am

问题 I have a java server that communicates with a java client via json-rpc. The client is supposed to report internal stats to the server which modifies the servers behaviour. Both client and server compenents are written in house so I can control what the client does and how it reports stats but is there a way I can verify that the client code hasn't been modified? If it has it will still service the client but using some default behaviours. The clients will be publicly available so it's not a

问题 I have wrote a server program in C# using TCPListner and a client program in Java using socket but I fail to send complex objects from Java client to C# server. When I send a simple string from Java client to C# server by converting the string into byte array, it always show some invalid characters at the start of message when converted back to String (using Encoding.utf8.getstring(bytesArray) ) in C# server. When I pass a String from C# to Java Client it shows invalid Header error. Please

问题 I'm continuing my research on solutions for our organization for our mobile app strategy. There's two somewhat conflicting requirements: it should be a web app in that all updates for users are immediate as we update the app on the server the app should leverage native UI widgets and native device features as much as possible With PhoneGap, the process appears to be that you'd normally keep the UI on the device, as part of the compiled app, and you'd hit your server via AJAX to deal with the

问题 im developing a multi-player card game that needs the clients to communicate with each other or a general server. i have never done this before so i need some direction or tutorial on how to achieve this. so far i have created the local, single person version of the game... 回答1: Sun has a good tutorial on writing a client/server pair complete with code examples. 回答2: So far i have created the local, single person version of the game... Great, I would suggest to continue with the local multi

问题 I have a webpage (built using HTML & jQuery) which displays the data from a MySQL database. I am using Flask to connect HTML with my database. However, my database gets updated every 15 minutes (using a separate Python Script). Currently, I stop the flask server, update the database and restart the Flask to update the webpage. My question is the following: Is there a way to update the MySQL database in the background without having to stop the flask server? I read about concepts of AJAX and

问题 I would like to know if my current implementation of BCrypt is correct, I am aware that I am not using BCrypt.checkpw() which may lead to an issue so that is the main reason I verify it here. Hasher.java container class: abstract public class Hasher { public static String hash(final char[] input) { String output = Hasher.hash(new String(input)); for (int i = 0; i < input.length; i++) { input[i] = 0; } return output; } public static String hash(final String input) { return BCrypt.hashpw(input,

问题 I want to add a feature where two clients can send to each other messages without stop and without the need of waiting. I have a script of the server: import socket import threading from datetime import datetime from random import randint global num num = 0 class serverThread(threading.Thread): def __init__(self, client, address): global num num = num + 1 self.id = num threading.Thread.__init__(self) self.client = client self.address = address print "serverThread init finished-" + str(self.id
