使用XMPP集成unieap做B/S版聊天软件

XMPP（Extensible Messaging and Presence Protocol，前称Jabber）是一种以XML为基础的开放式实时通信协议，是经由互联网工程工作小组（IETF）通过的互联网标准。XMPP因为被GoogleTalk应用而被广大网民所接触。开放式协议的好处就是，不区分客户端。就是说无论您使用gtalk、Facebook Chat还是网易泡泡，都可以实现相互间通话。也就是说，我们自己开发的客户端，也可以实现跟gtalk之间的聊天。

Openfire 采用Java开发，开源的实时协作（RTC）服务器基于XMPP（Jabber）协议。Openfire安装和使用都非常简单，并利用Web进行管理。单台服务器可支持上万并发用户。

       下面进入正题。

一、准备环境

Jdk1.6+

Openfire3.8.2：http://www.igniterealtime.org/这里要注意下，如果使用不同版本的openfire可能会和现有的源码出现兼容性问题。

Spark2.6.3：http://www.igniterealtime.org/

Nginx1.4.0

Mysql（这里使用Oracle也行）

 

二、部署openfire到Eclipse

参考：http://blog.csdn.net/ares1201/article/details/7737872

这篇文章写的很好很详细，这里就不重复说明了。

在部署完成后，登陆控制台，进入 服务器->服务器设置->HTTP绑定，把http绑定、ScriptSyntax都启用起来，这样才能以http的方式通过7070端口访问到服务器。

 

其中需要注意：

1、配置启动参数时，选中Arguments选项卡，在VM arguments中填入

-DopenfireHome="${workspace_loc:openfire_src}/target/openfire"，前面标红的-不要落了。

2、在控制台上输出openfire日志：

修改：/openfire_src/build/lib/dist/log4j.xml如下：

<!-- 添加一个打印控制台的日志 --> 

<appender name="STDOUT"class="org.apache.log4j.ConsoleAppender"> 

   <layout class="org.apache.log4j.PatternLayout"> 

        <paramname="ConversionPattern" value="%d [%24F:%-4L:%-5p][%x]-%m%n"/> 

   </layout> 

</appender> 

修改root

<root>

<level value="debug"/>

<appender-ref ref="STDOUT" />

<appender-ref ref="debug-out" />

<appender-ref ref="info-out" />

<appender-ref ref="warn-out" />

<appender-ref ref="error-out" />

</root>

工程中添加个目录，如下图

 

这样，在Eclipse控制台上就有openfire的日志输出了。

3、我在配置openfire的时候，全部使用的是域名的形式，我尝试了下使用ip，发现经常会有莫名其妙的问题，所以建议全部统一（不包括nginx部分）。

 

 

三、使用nginx部署strophe.js客户端

1、下载后的strophe.js解压，随访放个目录；

2、解压nginx，随访放个目录，修改conf/nginx.conf文件：

修改默认location的地址为strophe的目录，如下：

location/ {

            root   D:/workspaces/php;

            index  index.html index.htm;

        }

增加一个location为代理项；

location /http-bind {

            proxy_pass http://192.168.136.176:7070/http-bind/; 

            proxy_redirect off; 

            proxy_read_timeout 120; 

            proxy_connect_timeout 120; 

  

       } 

proxy_pass的意思是代理“http://192.168.136.176:7070/http-bind/”这个地址。效果就是访问nginx（80端口）下的http-bind应用时会直接跳转到7070端口下。这样可以保证strophe和openfire在一个域下，避免跨域访问。下面画个图解释下。

如图，目的就是让用户无论访问unieap（strophe）服务器还是访问openfire的时候都在同一个域下。

 

四、使用spark和浏览器实现对话

1、spark下载安装后，就可以直接连接到openfire服务器。

2、strophe解压后，里面有个example文件夹，里面有对应的例子，basic.html啊之类的。我这里下了个别人开发的聊天小程序，是用echobot.html那个例子改的。如果使用的是自带的例子，那么修改如下：

1）修改html中引用的jquery的地址为本地地址；

2）修改对应js里面的BOSH_SERVICE为'/http-bind/'。这里可以不加域，在写联系人的时候直接写上，如zhangsan@xxx，也可以在这里把域写死。

效果如下：

 

五、集成unieap用户

1、我使用的openfire外置数据库是mysql的，unieap工程主要修改修改的就是ofproperty这张表。这张表是具体的参数，可以通过console修改，我这里直接提供这个表的插入脚本了。

insert into `ofproperty` (`name`,`propValue`) values('admin.authorizedJIDs','admin@xueyi');

insert into `ofproperty` (`name`,`propValue`) values('httpbind.CORS.domains','*');

insert into `ofproperty` (`name`,`propValue`) values('httpbind.CORS.enabled','true');

insert into `ofproperty` (`name`,`propValue`) values('httpbind.enabled','true');

insert into `ofproperty` (`name`,`propValue`) values('httpbind.forwarded.enabled','false');

insert into `ofproperty` (`name`,`propValue`) values('jdbcAuthProvider.passwordSQL','select user_password fromup_org_user WHERE USER_ACCOUNT=?');

insert into `ofproperty` (`name`,`propValue`) values('jdbcAuthProvider.passwordType','md5');

insert into `ofproperty`(`name`, `propValue`)values('jdbcProvider.connectionString','jdbc:oracle:thin:@[host]:[port]:[entry]');

insert into `ofproperty` (`name`,`propValue`) values('jdbcProvider.driver','oracle.jdbc.driver.OracleDriver');

insert into `ofproperty`(`name`, `propValue`) values('jdbcProvider.password','[username]');

insert into `ofproperty`(`name`, `propValue`) values('jdbcProvider.user','[password]');

insert into `ofproperty` (`name`,`propValue`) values('jdbcUserProvider.allUsersSQL','SELECT USER_FULLNAME FROMup_org_user');

insert into `ofproperty` (`name`,`propValue`) values('jdbcUserProvider.emailField','USER_EMAIL');

insert into `ofproperty` (`name`,`propValue`) values('jdbcUserProvider.loadUserSQL','selectt1.USER_ACCOUNT,t1.USER_FULLNAME,t2.USER_EMAIL from up_org_usert1,up_org_user_ext t2 where t1.USER_ID = t2.USER_ID and t1.USER_ACCOUNT=?');

insert into `ofproperty` (`name`,`propValue`) values('jdbcUserProvider.nameField','USER_ACCOUNT');

insert into `ofproperty` (`name`,`propValue`) values('jdbcUserProvider.userCountSQL','SELECT COUNT(*) FROMup_org_user');

insert into `ofproperty` (`name`,`propValue`) values('jdbcUserProvider.usernameField','USER_FULLNAME');

insert into `ofproperty` (`name`,`propValue`) values('passwordKey','7yme2TF29702cfO');

insert into `ofproperty` (`name`,`propValue`)values('provider.admin.className','org.jivesoftware.openfire.admin.DefaultAdminProvider');

insert into `ofproperty` (`name`,`propValue`)values('provider.auth.className','com.neusoft.openfire.plugins.PhAuthProvider');

insert into `ofproperty` (`name`,`propValue`) values('provider.group.className','org.jivesoftware.openfire.group.DefaultGroupProvider');

insert into `ofproperty` (`name`,`propValue`)values('provider.lockout.className','org.jivesoftware.openfire.lockout.DefaultLockOutProvider');

insert into `ofproperty` (`name`,`propValue`) values('provider.securityAudit.className','org.jivesoftware.openfire.security.DefaultSecurityAuditProvider');

insert into `ofproperty` (`name`,`propValue`)values('provider.user.className','com.neusoft.openfire.plugins.PhUserProvider');

insert into `ofproperty` (`name`,`propValue`) values('provider.vcard.className','org.jivesoftware.openfire.vcard.DefaultVCardProvider');

insert into `ofproperty` (`name`,`propValue`) values('update.lastCheck','1404268354511');

insert into `ofproperty` (`name`,`propValue`) values('xmpp.auth.anonymous','true');

insert into `ofproperty` (`name`,`propValue`) values('xmpp.domain','xueyi');

insert into `ofproperty` (`name`,`propValue`) values('xmpp.httpbind.scriptSyntax.enabled','true');

insert into `ofproperty` (`name`,`propValue`) values('xmpp.session.conflict-limit','0');

insert into `ofproperty` (`name`,`propValue`) values('xmpp.socket.ssl.active','true');

 

其中标红的几句各位改成各自数据库的连接串，直接连接unieap支撑库。

2、在build/lib文件夹下加入Oracle驱动ojdbc14.jar。

3、加入类

com.neusoft.openfire.plugins.PhAuthProvider

com.neusoft.openfire.plugins.PhUserProvider

com.neusoft.openfire.plugins.MdFive

PhAuthProvider是用户验证的类，根据JdbcAuthProvider改写而来。

PhUserProvider是用户相关信息获取的类，根据JdbcUserProvider改写而来。

既然openfire都提供了jdbc和Oracle的支持了，为什么还要自己写呢？原因有两点：

a、因为openfire默认提供的数据库连接方式里面没有给出填写登陆数据库的用户名和密码的接口；

b、openfire提供了各种加密的方式，但是unieap的密码加密方式是先使用md5后使用base64混淆，所以这块要我们自己实现。

4、此步可不做：由于使用ant编译的工程，所以要调试jsp（servlet）的时候会比较麻烦，可以在调试时，把源文件地址指向work/jspc目录下。

5、重新使用ant工具编译工程，重启工程。分别使用spark和strophe连接到服务器测试，截图如下：

6、再截两张控制台的图，如下图。这时，unieap里面自带的用户就已经全部被openfire读出来了。

 

下图为控制台显示的在线用户。

 

六、代码（改编自jdbcauthprovider和jdbcuserprovider）

MdFive

public class MdFive {       public static String md5Encoder(Stringstr){              byte abyte0[] = null;              byte abyte1[] = null;              try {                        MessageDigest md =MessageDigest.getInstance("MD5");                        md.reset();                        abyte0 = str.getBytes();                     abyte1 = md.digest(abyte0);              }catch(NoSuchAlgorithmExceptione){                     e.printStackTrace();              }              BASE64Encoder encoder = newBASE64Encoder();              String result =encoder.encode(abyte1);              return result;       }             public static void main(String args[]){              System.out.println(md5Encoder("1"));       } }
