在上述实施方式中，投屏设备可以与服务器建立长连接，如投屏设备可以与服务器通过WebSocke建立长连接。示例性的，用户在欲通过终端设备向投屏设备进行投屏时，执行指示投屏设备显示投屏设备自身的投屏标识的触发操作。投屏设备在接收到该触发操作时，生成标识信息获取请求，并将该标识信息获取请求发送给服务器；或者，判断本地是否存储有自身的投屏标识信息，若本地存储有自身的投屏标识信息，则根据该投屏标识信息展示自身的投屏标识，若本地未存储有自身的投屏标识信息，则生成标识信息获取请求，并将该标识信息获取请求发送给服务器。相应的，服务器在接收到投屏设备发送的标识信息获取请求时，可以确定投屏设备的投屏标识信息，如生成投屏设备的投屏标识并确定该投屏标识的投屏标识信息或者获取本端存储的投屏设备的投屏标识信息，并将该投屏标识信息发送给投屏设备。从而，投屏设备在接收到服务器发送的投屏标识信息时，可以根据该投屏标识信息展示自身的投屏标识，并可以存储该投屏标识信息。相应的，终端设备可以采集投屏设备展示的投屏标识的投屏标识信息，生成携带有该投屏标识信息的投屏请求，并将该投屏请求发送给服务器，以请求服务器为其与投屏设备建立投屏连接。
在本实施例中，可以为每个设备的投屏标识信息设置有效期限，以降低投屏标识信息被非法窃取的可能性，提高投屏的安全性。示例性的，投屏设备在接收到显示投屏标识的触发操作时，可以生成标识信息获取请求，并将该标识信息获取请求发送给服务器；或者，判断本地是否存储有自身的有效的(即位于有效期限之内的)投屏标识信息，若本地存储有自身的有效的投屏标识信息，则根据该投屏标识信息展示自身的投屏标识，若本地存储的自身的投屏标识信息无效(即位于有效期限之外)，则删除本地存储的投屏标识信息，生成标识信息获取请求，并将该标识信息获取请求发送给服务器。相应的，服务器在接收到投屏设备发送的标识信息获取请求时，可以确定投屏设备的投屏标识信息，如判断本端是否存储有投屏设备的有效的投屏标识信息，若本端存储有投屏设备的有效的投屏标识信息，则将该投屏标识信息(或者该投屏标识信息以及该 投屏标识信息的有效期限信息)发送给投屏设备；若本端存储的投屏设备的投屏标识信息无效，则可以删除本端存储的该投屏设备的投屏标识信息，依据预先设置的投屏信息生成规则生成投屏标识并存储该投屏设备的投屏标识信息和有效期限信息，并将该投屏标识信息(或者该投屏标识信息以及该投屏标识信息的有效期限信息)发送给投屏设备。
投屏标识信息的有效期限可以灵活设置，如可以设置为5小时、12小时或24小时等。投屏标识可以采用生成方法生成，如可以通过设置随机函数随机生成不同的图像(包括图片和/或动图)，如可以通过Matlab工具生成函数图片，通过调用画图接口并将接口的参数设置为随机参数随机绘制图片，或者，在服务器保存有足够多的图片时，通过对服务器所存储的图片进行处理(如添加水印、密码或PIN码等)来生成图片，作为投屏设备的标识图片；或者，在生成图片后，采用所生成的多张图片生成动图，作为投屏设备的标识动图；和/或，通过为所生成的一张或多张图片添加特效(如转场特效或动效等)生成视频，或者，随机截取或选取服务器中存储的一段视频，并对该视频中的视频帧进行处理(如添加水印、密码或PIN码等)生成视频，作为投屏设备的标识视频，等等，本实施例不对此进行限制。

S103、为所述终端设备与所述投屏设备建立投屏连接。
在本实施例中，服务器在确定与投屏请求中所携带的目标投屏标识信息对应的投屏设备后，可以为发送该投屏请求的终端设备与该投屏设备建立投屏连接，以使得终端设备通过该投屏连接向投屏设备发送投屏数据进行投屏。

在上述实施方式中，终端设备向投屏设备进行投屏的方式可以根据需要设置，如终端设备可以将一需要进行播放的内容(如视频等)或自身的显示页面投屏至投屏设备。
示例性的，当投屏数据为视频内容时，终端设备可以基于用户的投屏操作确定需要进行投屏的视频，并将该视频的标识信息(如视频标识(Identifier，ID)或资源存储地址)发送给服务器。相应的，服务器可以根据该标识信息自资源数据库中获取该视频的视频数据，作为投屏数据，并将该投屏数据发送给投屏设备。从而，投屏设备在接收到服务器发送的投屏数据后，可以显示该投屏数据，即播放该投屏数据对应的视频。
当投屏数据为显示页面时，终端设备可以实时地或者在检测到自身所显示的页面或页面中的内容发生变化时，将自身的当前显示页面(包含页面中所显示的内容)的页面数据作为投屏数据发送给服务器。相应的，服务器可以接收终端设备发送的投屏数据后，可以将该投屏数据转发给投屏设备。从而，投屏设备在接收到服务器转发的投屏数据后，可以显示该投屏数据，即显示终端设备的当前显示页面。
在进行投屏的过程中，投屏设备也可以通过该通信连接向终端设备发送数据，如当用户通过终端设备之外的其他途径(如投屏设备的遥控器或投屏设备的调节按钮等)调整了投屏设备的音量、视频的播放进度、页面或页面中的内容时，投屏设备可以将该调整信息发送至终端设备，以同步对终端设备进行调整，如同步调整终端设备的音量、所投屏的视频的播放进度、当前显示页面或当前显示页面中所显示的内容等。
