server

问题 I have built a java server and I want to send messages to other clients .This is my client peer code.The program is able to print to the screen the message that one client sent to the server(but only the message that client sent) for example: new user:hi(this is what the server receives and also what the text client console shows) import java.io.IOException; import java.io.ObjectOutputStream; import java.net.Socket; import java.util.Scanner; import java.util.logging.Level; import java.util

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 I am building a client-server application in C with the source code taken from the book Advanced Programming in Unix Environment. In the server it is doing the following: struct addrinfo hint; memset(&hint, 0, sizeof(hint)); hint.ai_flags = AI_CANONNAME; hint.ai_socktype = SOCK_STREAM; hint.ai_addr = NULL; hint.ai_next = NULL; .... if ((n = sysconf(_SC_HOST_NAME_MAX))<0) { n = HOST_NAME_MAX; } if((host = malloc(n)) == NULL) { printf("malloc error\n"); exit(1); } if (gethostname(host, n)<0) {

问题 Lets say I want to create a front-end where multiple users can send a request to a server that scrapes some links off a website, would puppeteer be able to process it concurrently/atleast fast enough or should I consider a different method? Also, is there any possible way to load a page in a headless browser instance(with js enabled) on a mobile device? How could I go about coding my own headless browser in javascript if its possible? 回答1: You can always deploy your node.js instance via PM2

问题 I have a webgl application and quite a bunch of images. It has, however, come to my attention that images with given paths do not get recognized and hence are not used as textures in this application while others work just fine. for example images with paths like: assets/my_app/images/products/775/882/gHI1%201%200%20007%205NR%20H00968%2001b.jpg are not recognized, but whats worse is that I get no error whatsoever, except the fact that where a texture is supposed to be, I get none. however
