client

问题 All the examples I can find online are servers. I want to build a basic web crawler using epoll. So I need a basic client example to get me started. When I say basic I really mean a complete example that demonstrates multiple connections with sending and receiving of data to live web hosts. A simple HEAD request and its response for example. 回答1: Here is a sample c code for client socket with epoll. #include <stdlib.h> #include <stdio.h> #include <string.h> #include <errno.h> #include <sys

问题 The following code doesn't output anything(why?). #!/usr/bin/python import socket s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) s.connect(("www.python.org" , 80)) print s.recv(4096) s.close What do I have to change in order to output the source code of the python website as you would see when you go to'view source' in a browser? 回答1: HTTP is request/response protocol. You're not sending any request, thus you're not getting any response. s = socket.socket(socket.AF_INET, socket.SOCK

问题 Does anyone know the best way for a netty server handler to cancel receiving data from a web server? I have a server handler which proxies HttpRequests to a web server. However, when the requesting client cancels the request, I would like to stop receiving data on my server channel from the web server without closing the connection between the server handler and the web server. Does anyone know how I can go about doing this. Your response would be much appreciated. Thank you! 回答1: You could

问题 The problem is: when I put 2 controls of the same type on a page I need to specify different prefixes for binding. In this case the validation rules generated right after the form are incorrect. So how to get client validation work for the case?: the page contains: <% Html.RenderPartial(ViewLocations.Shared.PhoneEditPartial, new PhoneViewModel { Phone = person.PhonePhone, Prefix = "PhonePhone" }); Html.RenderPartial(ViewLocations.Shared.PhoneEditPartial, new PhoneViewModel { Phone = person

问题 I am using DefaultHttpClient in my current app. I read this article which states that the DefaultHttpClient is deprecated: http://developer.android.com/reference/org/apache/http/impl/client/DefaultHttpClient.html It points to this website: http://android-developers.blogspot.com/2011/09/androids-http-clients.html?m=1 which is too old and written in 2011. I am going to drop using DefaultHttpClient and follow this article which uses Apache’s HttpClient : http://loopj.com/android-async-http/ I

问题 I have to connect to a poorly implemented server that only understands Content-Type (capital-T) and not Content-type . How can I ask my JAX-WS client to send Content-Type ? I've tried: Map<String, List<String>> headers = (Map<String, List<String>>) ((BindingProvider)port).getRequestContext().get(MessageContext.HTTP_REQUEST_HEADERS); But headers is null . What am I doing wrong? 回答1: I have to connect to a poorly implemented server that only understands Content-Type(capital-T) and not Content

问题 I have a client on Android and server on c#. The client sends messages to server and it's fine. But I need server to send on request list of folders and files in specified directory and don't know how to do that, because client doesn't get any messages from server. The client's part of code that is intended to listen doesn't work, the application simply stucks until I close the server application, then it works again, but still doesn't read anything. Thanks in advance Client: package com.app
