登录认证 For Java

使用Java程序发送Http请求进行o2server登录认证 o2server向外提供了非常完整的restful服务，用户可以使用任何语言，编写代码发起http请求来进行o2server功能和业务的操作。大多数服务的调用，都需要进行登录认证，本篇详细介绍如何使用其他语言来发送http请求进行服务器认证。

发送用户名使用SSO进行登录认证

此示例演示如何通过登录用户名，和SSO相关的配置，使用单点认证的方式进行O2Server的登录认证，获取xtoken信息

涉及到加密解密，请使用非中文的唯一标识进行登录 ，中文登录 有可能会有找不到用户的问题。

一、o2Server平台SSO配置

1、使用管理员(或者xadmin)登录O2OA

2、打开系统菜单->控制面板->系统设置->SSO配置

打开控制面板

进入系统设置

进入SSO配置

3、添加SSO配置

4、重启o2server

二、编写登录代码

完整代码内容：

package net.o2oa.demos;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.URL;
import java.net.URLConnection;
import java.util.Date;
import org.apache.commons.codec.binary.StringUtils;
