问题 I'm trying to test a client-server simple implementation using localhost address. Here's the code. Server: /* * Sequential busy-waiting */ int main(int argc, char** argv) { int opt, client_addr_l, errsv; unsigned short port; struct sockaddr_in server_addr, client_addr; /* ... */ printf("Port number retrieved (%d), server is starting ...\n", port); /*TCP Socket creation*/ sock_ds = socket(AF_INET, SOCK_STREAM, 0); if(sock_ds == -1){ fprintf(stderr, "Socket creation error: %s\n", strerror(errno

问题 I created an Android App with PhoneGap:Build and the FB Connect Plugin. The app works fine and the FB Plugin, too. Just one tiny thing isn't working yet. I won't to post something after submiting a button which works, too. At the first time the user has to login and grant permissions to the FB App and them the post is published. That's the way it should be. And the next time the user submits the post should be published without the whole permission thing but this isn't working!? FB shows a

问题 [edit] Seems my question was asked nearly 10 years ago here... Emulating accept() for UDP (timing-issue in setting up demultiplexed UDP sockets) ...with no clean and scalable solution. I think this could be solved handily by supporting listen() and accept() for UDP, just as connect() is now. [/edit] In a followup to this question... Can you bind() and connect() both ends of a UDP connection ...is there any mechanism to simultaneously bind() and connect()? The reason I ask is that a multi

问题 I am using Facebook's Facebook Query Language (FQL) to get information on a user once I already know his user id. When I enter the following URL into Firefox, it returns the correct XML for the request: http://api.facebook.com/method/fql.query?query=SELECT name FROM user WHERE uid= * * ' Namely it returns the user's name. Note: please don't suggest using Graph API as I will in fact be using FQL for things not implemented in Graph yet like networks, this is just a simple example. BUT, when I

问题 I need start using the mysqli extension but I'm finding all kinds of conflicting info depending on how all the info is that I'm trying to use. For example, my header connects to a 'config.php' file that currently looks like this: <?php $hostname_em = "localhost"; $database_em = "test"; $username_em = "user"; $password_em = "pass"; $em = mysql_pconnect($hostname_em, $username_em, $password_em) or trigger_error(mysql_error(),E_USER_ERROR); ?> But when I go to php.net I see that I should be

问题 I have a personal project in SailsJS, Passport-Local and PostgreSQL. I managed to get connection and save users in PostgreSQL DB. But I have big problem with session storing. From what I know SailsJS is using Connect to get it done. Previous working code for MongoDB: connections: { prodMongodbServer: { adapter: 'sails-mongo', host: 'localhost', port: 27017, //user: '', //password: '', database: 'sails-auth' } }, session: { adapter: 'mongo', host: 'localhost', port: 27017, db: 'sails-auth',

问题 As root: GRANT ALL PRIVILEGES ON * . * To 'JKR'@'%' IDENTIFIED BY ""; FLUSH PRIVILEGES; In PHP: $con = new PDO("mysql:host=127.0.0.1;dbname=jkr;charset=utf8", "JKR", ""); Error message: Uncaught exception 'PDOException' with message 'SQLSTATE[HY000] [1044] Access denied for user ''@'localhost' to database 'jkr'' in C:\xampp\www\jkr\core\connect.php:6 Only works as root for some reason ...

问题 I am using Connect on node.js with connect-redis as session store. Is there a way to attach a callback function to the the event when the session expires, so I can backup data from the session, before it gets deleted? 回答1: Its impossible because the expiration is done at redis side. The connect-redis session store uses setex . https://github.com/visionmedia/connect-redis/blob/master/lib/connect-redis.js#L80 You can set a insane maxAge and do expiration by yourself using setInterval OR Fork

问题 Okay, after a successful user login, an alertbox will display the username and then another form will pop up that enables the user to change his password. I want to use the value of the username (from login form) in a conditional statement to be able to change the password. How do i get this value that came from another form? Thanks. View image here: 回答1: What does confuse u? Pass the username to the next form, I don't see the reason why the 3rd form has to know about any other. It would be

问题 I used visual2010 to write a simple app with httpWebRequest class. The very first time of running the app, it'd work but after some successes, it was stuck with warning "unable to connect the remote server". I have read a lot in net but not much clues could done, almost said because the anti virus soft or firewall cause the problem, but when i'd turn off both, it still does not work. I also reinstall visual2010 but the problem still using System.Collections.Generic; using System.Linq; using
