本发明目的的实现、功能特点及优点将结合实施例，参照附图做进一步说明。
应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
本发明提供一种互动课堂系统实现方法。
本发明中用户终端需要安装播放课件的客户端软件，而客户端软件的安装需要输入软件授权码以及服务器地址，才能确保客户端软件的成功安装，其中，软件授权码是用户终端注册到服务器端时生成。
参照图1，图1为本发明互动课堂系统实现方法第一实施例的流程示意图。
在第一实施例中，该互动课堂系统实现方法包括：
步骤S10，服务器端确定用户终端的联网状态；
服务器端确定用户终端联网状态的方式有多种，譬如：服务器端发送消息给用户终端，用户终端予以响应，表明用户终端处于联网的状态，反之，则表明用户终端由于各种原因现处于非联网的状态。
步骤S20，当用户终端处于联网状态时，服务器端接收用户终端的认证消息并认证所述认证消息，当所述用户终端认证通过时，发送认证通过消息和课件下载地址至用户终端，供用户终端下载和播放待播放课件；
当用户终端处于联网状态时，用户终端发送认证消息给服务器端，服务器端接收认证消息，并通过认证消息对用户终端进行认证，当用户终端认证通过时，服务器端发送认证通过消息和课件下载地址至用户终端，用户终端点击进入下载地址下载待播放的课件，下载完成后，使用用户终端的客户端软件播放课件。
步骤S30，当用户终端处于非联网状态时，服务器端将待播放课件和用户终端对应的XML文件传输至用户终端，在接收到用户终端的激活请求后，根据该激活请求生成激活码，供用户终端根据所述激活码进行激活并播放待播放课件。
当用户终端处于非联网状态时，服务器端将待播放课件和用户终端对应的XML文件传输至用户终端，其方式有多种，譬如：服务器端可以通过外部存储设备将待播放课件和用户终端对应的XML文件拷贝至用户终端，也可以通过数据线的方式，将待播放课件和用户终端对应的XML文件传输至用户终端，而用户终端接收到服务器端的待播放课件和用户终端对应的XML文件后，用户终端向服务器端发出激活请求，服务器端接收到用户终端的激活请求后，根据该激活请求生成激活码，供用户终端激活后，播放待播放课件。
本实施例中处于联网状态的用户终端需要发送认证消息给服务器端以获得认证通过消息及课件下载地址才能获取课件予以播放；处于不联网状态的用户终端需要接收服务器端的激活码供激活用户终端才能播放待播放课件。通过上述两种方式，实现用户终端不管处于联网状态还是非联网状态，均需要得到服务器端的授权才能播放课件，解决了用户终端随意播放课件的问题，达到了用户终端即使获得了课件以及解密密码，也需要服务器端授权后，才能播放课件的效果。
参见图2，图2为本发明互动课堂系统实现方法第二实施例的流程示意图。
在第二实施例中，该互动课堂系统实现方法的步骤与第一实施例的步骤基本相同，其不同之处在于，所述步骤S10之前，该互动课堂系统实现方法还包括：
步骤S08，服务器端对上传的课件进行分类处理和加密处理并存储；
服务器端接收到上传的课件后，对课件进行分类处理，服务器端对上传的课件进行分类处理的方式有多种，譬如：按照学段信息、学科信息进行分类，学段信息包括
幼儿园、小学、初中、高中等信息，学科信息语文、数学、英语等信息，通过先选学段、再选择学科的方式上传课件，也便于下次查找、下载课件；对上传的课件进行分类处理后，服务器端对该课件进行加密处理并存储，在用户终端获取了课件后，也需要进行相对应的解密处理才能播放该课件。
步骤S09，服务器端根据所述课件生成与播放该课件的用户终端匹配的XML文件，该XML文件包括软件授权码，课件名称和课件所属分类。
服务器端根据预设分类选择课件，譬如：根据先选学段、再选学科的方式选择课件，然后，服务器端针对所选择的课件，根据该课件、将要播放该课件的用户终端生成该课件对应的XML文件，该XML文件包括与用户终端相匹配的软件授权码、课件名称以及课件所属分类。当用户终端的软件授权码与XML文件的软件授权码一致时，用户终端才能播放XML文件的课件名称对应的待播放课件。
本实施通过分类处理对课件进行了有效的管理，方便了服务终端或用户终端根据预设分类进行选择或者下载课件；通过加密处理防止了优质课件以及所有课件一经获取，后续可以随意播放的问题发生；再有，本发明通过生成XML文件，使得服务器端上的某些课件只能与XML文件的软件授权码一致的用户终端才能播放，进一步地防止了优质课件以及所有课件的解密密码被获取的情况，任意的用户终端随意播放课件的问题发生。
参见图3，图3为图1中当用户终端处于联网状态时，服务器端发送课件下载地址至用户终端步骤的细化流程示意图。
进一步地，步骤S20包括：
步骤S201，服务器端接收用户终端发送的包含软件授权码的认证消息，并将认证消息中的软件授权码与服务器端存储的XML文件中的软件授权码进行匹配；
当用户终端处于联网状态时，用户终端发送包含软件授权码的认证消息给服务器端，该软件授权码为用户终端的软件授权码，服务器端接收用户终端的认证消息，将用户终端的软件授权码与服务器端存储的XML文件中的软件授权码进行匹配，如一致，即表示匹配成功；如不一致，即表示匹配不成功。
步骤S202，当匹配成功时，服务器端发送认证通过消息与课件下载地址至用户终端，供用户终端选择课件，对选择的课件进行解密处理并播放；
当匹配成功时，服务器端发送认证通过消息与课件下载地址至用户终端，用户终端接收到认证通过消息与课件下载地址后，进入下载地址下载待播放的课件，下载完成后，打开用户终端的客户端软件，添加待播放课件，进行解密处理后，使用客户端软件播放待播放课件。
步骤S203，当匹配不成功时，服务器端提示用户终端匹配不成功，以及该用户终端为非授权用户终端。
当匹配不成功时，服务器发送匹配不成功的消息，以及用户终端为非授权的用户终端的信息向用户终端进行提示，用户终端接收到匹配不成功的消息、以及用户终端为非授权的用户终端的信息后，重新发送包含正确的软件授权码的认证消息给服务器端。
本实施例通过上述方式，保证了当用户终端处于联网状态时，用户终端需要通过服务器端的认证，通过后服务器端才将课件下载地址发送给用户终端，供用户终端下载课件予以播放，防止了用户终端在联网状态下，随意获取或播放课件的问题的发生。
参见图4，图4为图1中当用户终端处于非联网状态时，服务器端生成激活码的步骤的细化流程示意图。
进一步地，步骤S30包括：
步骤S301，当用户终端处于非联网状态时，服务器端将待播放课件和用户终端对应的XML文件传输至用户终端，接收用户终端的激活请求，该激活请求包括用户终端读取XML文件获取的软件授权码，和根据硬盘序列号生成的硬件授权码；
当用户终端处于非联网状态时，服务器端将待播放课件与XML文件存放到用户终端的预设目录，其方式有多种：譬如：服务器端可以通过外部存储设备将待播放课件和用户终端对应的XML文件拷贝至用户终端的预设目录，也可以通过数据线的方式，将待播放课件和用户终端对应的XML文件传输至用户终端的预设目录，而当待播放课件与XML文件存放到用户终端的预设目录后，用户终端读取XML文件中的软件授权码，根据自身的硬盘序列号生成硬件授权码，并根据软件授权码和硬件授权码向服务器端发起激活请求。
步骤S302，服务器端根据包含软件授权码和硬件授权码的激活请求生成激活码，供用户终端根据所述激活码进行激活并播放待播放课件。
服务器端接收到包括软件授权码和硬件授权码的激活请求后，服务器端根据软件授权码、硬件授权码生成激活码，并将激活码传输至用户终端，用户终端根据激活码激活用户终端的客户端软件，使用激活后的客户端软件，先打开客户端软件，添加待播放课件进行解密操作后播放待播放课件。
本实施例中用户终端处于非联网状态时，即使用户终端获取课件的解密密码、课件以及客户端软件的软件授权码，也需要发送软件授权码，硬件授权码给服务器端，获取服务器端的激活码，激活后客户端软件后才能播放课件。
本发明进一步提供了一种服务器端。
