问题 I have tried to set up Redis server on my windows 7 32 bit. I did not find a 32-bit supportive version of Redis. How can I do this? Advance thanks. 回答1: Download the .zip file to your hard drive. Unzip the files into any location, such as ‘C:\Program Files\Redis\’. Add the path of your Redis folder as a Windows ‘environment variable.’ Open your Command Prompt (ex: cmd.exe). install redis server redis-server --service-install start redis server redis-server --service-start save and stop the

Check errors when calling http.ResponseWriter.Write()

问题 Say I have this http handler: func SomeHandler(w http.ResponseWriter, r *http.Request) { data := GetSomeData() _, err := w.Write(data) } Should I check the error returned by w.Write ? Examples I've seen just ignore it and do nothing. Also, functions like http.Error() do not return an error to be handled. 回答1: It's up to you. My advice is that unless the documentation of some method / function explicitly states that it never returns a non- nil error (such as bytes.Buffer.Write()), always check

问题 I want to access files located in a folder on the FTP server by giving ftp's hostname and display it in my app which is developed using the android studio. It should be dynamic, that is it should reflect all the changes done inside the folder of which I have given a specific URL, that is if something is deleted or inserted, it should be reflected in the app. I am unable to connect to FTP server and my app crashes.

本文地址： http://blog.csdn.net/kongxx/article/details/7259827 Java Socket实战之一 单线程通信 Java Socket实战之二 多线程通信 前面两篇文章介绍了怎样建立Java Socket通信，这一篇说一下怎样使用Java Socket来传输对象。 首先需要一个普通的对象类，由于需要序列化这个对象以便在网络上传输，所以实现java.io.Serializable接口就是必不可少的了，入下： package com.googlecode.garbagecan.test.socket.sample3; public class User implements java.io.Serializable { private static final long serialVersionUID = 1L; private String name; private String password; public User() { } public User(String name, String password) { this.name = name; this.password = password; } public String getName() { return name; } public void setName

Java ServerSocket won't send or receive messages from client

问题 I have these two classes Client.java and Server.java , each containing a main method. The idea is very simple and the code in them is very similar. The objective I'm trying to achieve is opening a server that listens on a specific port using ServerSocket , then open a client and connect to the server using Socket so that I can finally send messages from client to server and reverse until I close the connection. So far, I tried the easiest example, opened server on port 4444, then on the same
