through socket

The socket programming here does not mean using the XMLHttpRequest object, but actually creating a socket to implement and send and receive data. Use JavaScript to invoke Java's NIO interface to implement socket programming. Implement a simple echoserver, create a file: Echoserver.js var socket = __import__ ('

Socket Client socketjsphp Want to use PHP to do a socket client, you can implement a connection, and then send a message to the server multiple times. The concrete idea is this:To make a page, this page has a button and the Message bar, click the button to send the content of the message bar to the server, then click again send, and do not need to reconnect, but the page opened with the server connecti

C language Listen () function: Waiting for connectionheader file: #include To define a function: int listen (int s, int backlog); Function Description: Listen () is used to wait for the socket connection of the parameter S. The parameter backlog specifies the maximum connection requirements that can be processed at the same time, and if the number of connections reaches this limit, the client side will receive a econnrefuse

TCP protocol(Transmission control protocol, transfer control protocol) isConnection oriented transmission layer in TCP/IP System),TCP protocolIt can detect and recover possible packet loss, duplication, and other errors from the host to the Host channel provided by the IP layer. TCP is a connection-oriented protocol: before using it for communication, two applicationsProgramFirst, establish a TCP connection. TCP can provide duplex and reliable services in the network. Reading directory: 1. T

Synchronizing client Sockets sample The following example program creates a client that is connected to the server. The client is generated with a synchronous socket, so the execution of the client application is suspended until the server returns a response. The application sends a string to the server and then displays the string returned by the server in the console. C# using System; using System.Net; using System.Net.Sockets; The using Sys

Blocking socket and non-blocking Socket Read operationsFor a blocked socket, when no data exists in the socket receiving buffer, the read call will be blocked until data arrives. Back. When the data volume in the socket buffer is smaller than the expected data volume, the ac

What are the main causes of network disconnection? To sum up, there are two main types: 1. ClientProgramException. In this case, we can handle it well, because the client program will cause a socket exception of connectionreset on the server side (that is, the 10054 exception in Winsock2) when it exits abnormally ). You only need to handle this exception on the server. 2. network link exceptions. Such as network cable disconnection, switch pow
