client-server

问题 Just trying to create a chat server-client This is the server waiting for a client connection (optional)* TcpListener serverSocket = new TcpListener(8888); int requestCount = 0; TcpClient clientSocket = default(TcpClient); serverSocket.Start(); Console.WriteLine(" >> Server Started"); clientSocket = serverSocket.AcceptTcpClient(); Console.WriteLine(" >> Accept connection from client"); Then, the client connects to the server (optional)* System.Net.Sockets.TcpClient clientSocket = new System

问题 On every new client connection forked server process different processes(other children of server i.e. exec) couldn't identify that client with same fd in used in forked child. How can I differentiate client on other processes ?? accept call is returning same value if file descriptor new sockfd /* server process */ #include <ctype.h> #include <sys/types.h> #include <sys/socket.h> #include <netinet/in.h> #include <signal.h> #define SIZE sizeof(struct sockaddr_in) void catcher(int sig); int

问题 I just have began to study ReactJS and found that it gives you 2 ways to render pages: server-side and client-side. But, I can't understand how to use it together. Is it 2 separate ways to build the application, or can they be used together? If we can use it together, how to do it - do we need to duplicate the same elements on the server side and client side? Or, can we just build the static parts of our application on the server, and the dynamic parts on the client side, without any

问题 I am currently working on a project that requires the client requesting a big job and sending it to the server. Then the server divides up the job and responds with an array of urls for the client to make a GET call on and stream back the data. I am the greenhorn on the project and I am currently using Spring websockets to improve efficiency. Instead of the clients constantly pinging the server to see if it has results ready to stream back, the websocket will now just directly contact the

问题 I am attempting to make a simple server so that two clients can communicate with each other. The main server code accepts the two client connections and then forks off a process that uses execl to generate a personal server between the two clients so that the main server can continue looking for new connections. Everything seems to work correctly until the personal server attempts to contact the clients and they both receive gibberish, if anyone knows what could cause this please let me know.

问题 Here is how I send data from the client (coffeescript & dajaxice): imageData = canvas.toDataURL("image/png") Dajaxice.draw.saveImage( @saveImage_callback, {'image': imageData } ) Here is how I save my image on the server (taken from this answer) @dajaxice_register def saveImage(request, image): imageData = re.search(r'base64,(.*)', image).group(1) output = open('image.png', 'wb') output.write(imageData.decode('base64')) output.close() I would like to load the image and send it like so:
