阿里软件免登录示例

使用java来开发阿里软件的朋友来看了，这里是一个java调用的免登录入口的例子：

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.UnsupportedEncodingException;
import java.net.HttpURLConnection;
import java.net.URL;
import java.net.URLEncoder;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.HashMap;
import java.util.Map;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;

import com.alisoft.sip.sdk.isv.SignatureUtil;//此包需要在阿里软件网站上进行下载：sip-sdk-for-java-1.0.jar

/**

 */
public class ValidaterAction extends Action {
	/*
	 * Generated Methods
	 */

	/** 
	 * Method execute
	 * @param mapping

	 */
	public static java.text.SimpleDateFormat SIP_TIMESTAMP_FORMATER = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");//时间格式
		
		public ActionForward execute(ActionMapping mapping, ActionForm form,HttpServletRequest request, HttpServletResponse response) {
			
			String code=null,result=null;//code为返回的状态码,result为返回信息
			
			//在软件应用中心跳转到ISV应用时的URL参数中取得,user_id、app_instance_id和token
			Map<String, String> map = new HashMap<String, String>();//输入各个参数
			String sip_timestamp = SIP_TIMESTAMP_FORMATER.format(new Date());
			map.put("token", request.getParameter("token"));

			map.put("sip_timestamp", sip_timestamp);
	//签名,生成sip_sign参数,SignatureUtil是下载中心中sip-sdk-for-java-1.0.jar中的一个类,ISV可以将包下载上来,加载到工程中.
			String sign = SignatureUtil.Signature(map,map.get("sip_appsecret"));
			map.put("sip_sign", sign);

	//组织要提交的参数
			StringBuffer buffer = new StringBuffer();

				} else {

				}
				Object value = entry.getValue();
				buffer.append(entry.getKey()).append("=").append(
						encodeURL(value) );
			}
			String queryString=buffer.toString();
	//发送访问请求, 目前阿里软件的服务集成平台（SIP）的接口测试地址是：http://sipdev.alisoft.com/sip/rest，生产环境地址是：http://sip.alisoft.com/sip/rest,这里使用测试接口先，到正式上线时需要做切换
		try{
			HttpURLConnection conn = (HttpURLConnection) new URL("http://sipdev.alisoft.com/sip/rest").openConnection();

			conn.setDoOutput(true);

			BufferedReader reader = new BufferedReader(new InputStreamReader(conn.getInputStream(), charset));//设置编码
			StringBuffer outbuffer = new StringBuffer();
			String line;
			while ((line = reader.readLine()) != null) {
				outbuffer.append(line);
			}
			reader.close();
	//解析接口返回值
	        code = conn.getHeaderField("sip_status");//返回的状态码
	        conn.disconnect();
	        result=outbuffer.toString();//返回内容
			}catch(Exception e){e.printStackTrace();}
			if (result!=null) {
				// 请求返回的status为成功状态
				if (code.equals("9999")) {
	//解析返回的结果result,确定用户的身份......
				}
			}
			return null;//免登录成功后你可以根据自己的业务逻辑跳转
		}
		
		
		
		
		
		private String getChareset(String contentType) {
			int i = contentType == null ? -1 : contentType.indexOf("charset=");
			return i == -1 ? "GBK" : contentType.substring(i + 8);//UTF-8
