下面的例子代码展现了如何使用服务端API对基于Http协议的流媒体播放请求进行访问控制，基于Http协议的流媒体播放技术在Wowza Stream Engine 4中包括Cupertino (iOS hls)和MPEG-DASH。

注意：在这个例子中，只要是Http协议的流媒体请求，都将统一进行访问控制。

package com.wowza.wms.example.module;

import com.wowza.wms.httpstreamer.model.IHTTPStreamerSession;
import com.wowza.wms.module.*;
import com.wowza.wms.application.*;

public class ModuleAccessControlHTTPStreaming extends ModuleBase
{
	public void onHTTPSessionCreate(IHTTPStreamerSession httpSession)
	{
		boolean isGood = true;
		
		String ipAddressClient = httpSession.getIpAddress();
		String ipAddressServer = httpSession.getServerIp();
		String queryStr = httpSession.getQueryStr();
		String referrer = httpSession.getReferrer();
		String cookieStr = httpSession.getCookieStr();
		String userAgent = httpSession.getUserAgent();
		
		IApplicationInstance appInstance = httpSession.getAppInstance();
		String streamName = httpSession.getStreamName();
		
		// Here you can use the request and session information above to determine 
		// if you want to reject the connection
		// isGood = true/false;
		
		getLogger().info("ModuleAccessControlHTTPStreaming.onHTTPSessionCreate["+appInstance.getContextStr()+":"+streamName+"]: accept:"+isGood);
		
		if (!isGood)
			httpSession.rejectSession();
	}
}
		

使用如何使用Wowza IDE开发Wowza的扩展模块编译上面的代码,将这个模块添加到/conf/[app-name]/Application.xml 文件的模块集合中:

<Module>
	<Name>ModuleAccessControlHTTPStreaming</Name>
	<Description>Access control for HTTP streams</Description>
	<Class>com.wowza.wms.example.module.ModuleAccessControlHTTPStreaming</Class>
</Module>
		

在下面的代码展示了如何使用服务端API对使用Http Live Streaming协议的流媒体请求进行访问控制。

package com.wowza.wms.example.module;

import com.wowza.wms.httpstreamer.cupertinostreaming.httpstreamer.*;
import com.wowza.wms.module.*;
import com.wowza.wms.application.*;

public class ModuleAccessControlCupertinoStreaming extends ModuleBase
{
	public void onHTTPCupertinoStreamingSessionCreate(HTTPStreamerSessionCupertino httpCupertinoStreamingSession)
	{
		boolean isGood = true;
		
		String ipAddressClient = httpCupertinoStreamingSession.getIpAddress();
		String ipAddressServer = httpCupertinoStreamingSession.getServerIp();
		String queryStr = httpCupertinoStreamingSession.getQueryStr();
		String referrer = httpCupertinoStreamingSession.getReferrer();
		String cookieStr = httpCupertinoStreamingSession.getCookieStr();
		String userAgent = httpCupertinoStreamingSession.getUserAgent();
		
		IApplicationInstance appInstance = httpCupertinoStreamingSession.getAppInstance();
		String streamName = httpCupertinoStreamingSession.getStreamName();
		
		// Here you can use the request and session information above to determine 
		// if you want to reject the connection
		// isGood = true/false;
		
		getLogger().info("ModuleAccessControlCupertinoStreaming.onHTTPCupertinoStreamingSessionCreate["+appInstance.getContextStr()+":"+streamName+"]: accept:"+isGood);
		
		if (!isGood)
			httpCupertinoStreamingSession.rejectSession();
	}
}
