下面介绍了如何用AuthenticateUsernamePasswordProviderBase实现类以及ModuleRTMPAuthenticate模块来获得RTMP连接时的用户名/密码并到你自己的数据库中做认证。

<Module>
	<Name>ModuleRTMPAuthenticate</Name>
	<Description>ModuleRTMPAuthenticate</Description>
	<Class>com.wowza.wms.security.ModuleRTMPAuthenticate</Class>
</Module>
		

1. 下载mySQL的JDBC驱动(http://dev.mysql.com/downloads/connector/j/5.0.html),然后拷贝适当的MySQL JDBC .jar 文件到Wowza Media Server 的/lib 文件夹中。
   
   
2. 参考下面的代码，建立你自己的数据库认证模块:
   

   package com.wowza.wms.example.authenticate;
   
   import com.wowza.wms.authentication.*;
   import com.wowza.wms.logging.WMSLoggerFactory; 
   import java.sql.*;
   
   public class AuthenticateUsernamePasswordProviderExample extends AuthenticateUsernamePasswordProviderBase
   {
   	public String getPassword(String username)
   	{
   		// return password for given username		
   		String pwd = null;
   		
   		WMSLoggerFactory.getLogger(null).info("Authenticate getPassword username: " + username);
   		
   		Connection conn = null;
   		try 
   		{
   			conn = DriverManager.getConnection("jdbc:mysql://localhost/wowza?user=root&password=mypassword");
   
   			Statement stmt = null;
   			ResultSet rs = null;
   
   			try 
   			{
   				stmt = conn.createStatement();
   				rs = stmt.executeQuery("SELECT pwd FROM users where username = '"+username+"'");
   				while (rs.next())
   				{
   					pwd = rs.getString("pwd");
   				}
   
   			} 
   			catch (SQLException sqlEx) 
   			{
   				WMSLoggerFactory.getLogger(null).error("sqlexecuteException: " + sqlEx.toString());
   			} 
   			finally 
   			{
   				if (rs != null) 
   				{
   					try 
   					{
   						rs.close();
   					} 
   					catch (SQLException sqlEx) 
   					{
   
   						rs = null;
   					}
   				}
   
   				if (stmt != null) 
   				{
   					try 
   					{
   						stmt.close();
   					} 
   					catch (SQLException sqlEx) 
   					{
   						stmt = null;
   					}
   				}
   			}
   
   			conn.close();
   		} 
   		catch (SQLException ex) 
   		{
   			// handle any errors
   			System.out.println("SQLException: " + ex.getMessage());
   			System.out.println("SQLState: " + ex.getSQLState());
   			System.out.println("VendorError: " + ex.getErrorCode());
   		}
   		
   		return pwd;
   	}
   	public boolean userExists(String username)
   	{
   		// return true is user exists
   		return false;
   	}
   }
   		

3. 部署这个Class:
   
   注意:在最新的Wowza Streaming Engine 4中下面的参数usernamePasswordProviderClass已经被改名为securityPublishUsernamePasswordProviderClass。
   
   1. 针对RTMP推流的验证，请在[install-dir]/conf/[application]/Application.xml文件的<Properties>中添加下面的配置参数。
      

      <Property>
      	<Name>usernamePasswordProviderClass</Name>
      	<Value>com.wowza.wms.example.authenticate.AuthenticateUsernamePasswordProviderExample</Value>
      </Property>
      			

   2. 针对RTSP推流的验证，请在[install-dir]/conf/Authentication.xml /Digest Properties(或/Basic Properties)中添加usernamePasswordProviderClass参数:
      

      <Method>
      	<Name>digest</Name>
      	<Description>Digest Authentication</Description>
      	<Class>com.wowza.wms.authentication.AuthenticateDigest</Class>
      	<Properties>
      		<Property>
      			<Name>passwordFile</Name
      			<Value>${com.wowza.wms.context.VHostConfigHome}/conf/publish.password</Value>
      		</Property>
      		<Property>
      			<Name>realm</Name>
      			<Value>Streaming Server</Value>
      		</Property>
      		<Property>
      			<Name>usernamePasswordProviderClass</Name>
      			<Value>com.wowza.wms.example.authenticate.AuthenticateUsernamePasswordProviderExample</Value>
      		</Property>
      	</Properties>
      </Method>
      		

4. 最后，重启Wowza Streaming Engine。
