client

问题 When I deploy the same service on different machines as they have different information that I need , how can I use my client gracely to consume these service . 回答1: You need to define the service endpoint you want to connect to in your client's config. You cannot define a list of endpoints - if you need load-balancing features, you need to implement those on the server side and "hide" them behind a single service endpoint. With .NET 4 and WCF 4, you have new capabilities you could check out:

问题 I am writing a client library for a model railway controller over TCP. The server is embedded in the control unit. When the client sends a command to the server, for example set(5, addr[3]) the server responds with a reply header <REPLY set(5, addr[3])> , results for that command and if there was an error. Because all this stuff is asynchronous, I have to match the replies with the commands. (Even if the client would only send one command and then wait for the response there are serverside

问题 I'm trying to implement select(..) on the client side with creating multiple sockets apart from the TCP socket to recv(..) from the server. I want to receive the data on different recv(..) of different sockets created using select(..). The code doesn't seem to function as expected. Please help.

问题 I am implementing a chat server, and I currently have a list of client sockets I'd like to send information through, the issue is that the client exists in a raw_input() state in order to send the message to be relayed through the server, and each client's buffer is being filled up until that client itself enters something in the raw_input() field, at which point it prints its receive buffer as a single line chunk. I would like each client to get an immediate display of what's in their buffer

问题 We have Bugzilla installed on a computer which we would like to act as a server. I have yet to install Bugzilla on my computer, the client. Can you point me to some references which describes how Bugzilla works as a server? What I would like to do is file bugs from client computers and this will be reflected to the Bugzilla server. How do we access the Bugzilla server? Is it a requirement that all of the clients has the Bugzilla software? 回答1: Bugzilla is a web based application. You don't

问题 this week I was trying Jersey, CXF and RestEasy clients (using JSON) as a standalone application(testing purposes), and I notice something. In Jersey I can enable logs with one line of code: Client client = Client.create(); client.addFilter(new LoggingFilter(System.out)); WebResource webResource = client.resource("http://localhost:8080/IT1/MB1"); ....
