Description

一种广告防屏蔽的方法和装置 技术领域
本发明涉及互联网技术领域，特别涉及一种广告防屏蔽的方法和装置。
背景技术
现有的浏览器往往集成有广告屏蔽插件，其可以对网页中的广告进行屏蔽，以提升用户体验，然而，这给各个网站提供商带来了严重的损失，极大的降低了其广告收入。
网页的网页内容一般由文字、图片、视频等资源组成，浏览器在加载网页内容时，可以对这些资源各自的URL(Uniform Resource Locator，统一资源定位符)发起访问请求，以获取上述资源。广告屏蔽插件可以对浏览器待访问的上述URL进行识别，如果识别出该URL为广告类URL，则广告屏蔽插件可以阻止浏览器对该URL进行访问，导致浏览器无法获取到相应的广告内容，进而无法对广告进行显示。目前亟需一种效果较好且成本较低的广告防屏蔽的方法。

附图说明
为了更清楚地说明本发明实施例中的技术方案，下面将对实施例描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其它的附图。

图2是本发明实施例提供的一种广告防屏蔽的方法流程图；
图3是本发明实施例提供的一种广告防屏蔽的装置结构示意图；
图4是本发明实施例提供的一种边缘服务器的结构示意图。
具体实施方式
为使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明实施方式作进一步地详细描述。
本发明实施例提供了一种广告防屏蔽的方法，该方法的执行主体可以是边缘服务器或代理服务器，边缘服务器或代理服务器可以是CDN(Content Delivery Network，内容分发网络)集群中的任意缓存服务器，其可以接收任意终端(如智能手机、平板电脑)对某一网页的访问请求，然后可以基于该访问请求，将缓存的该网页的网页内容返回给上述终端；如果没有缓存该网页的网页内容，边缘服务器或代理服务器可以从源站(网站提供商)获取该网页的网页内容，然后将获取的该网页的网页内容返回给上述终端。相应的网络场景可以如图1所示。上述边缘服务器中可以包括处理器、存储器、收发器，处理器可以用于进行下述流程中广告防屏蔽的处理，存储器可以用于存储下述处理过程中需要的数据以及产生的数据，收发器可以用于接收和发送下述处理过程中的相关数据。本实施例以执行主体为边缘服务器进行说明，执行主体为代理服务器的情况与之类似，不再一一赘述。
下面将结合具体实施方式，对图2所示的一种广告防屏蔽的方法的处理流程进行详细的说明，内容可以如下：
步骤201：接收终端对目标网页的第一访问请求，获取目标网页的网页内容。
在实施中，当某用户想要访问某网页(可称为目标网页)时，该用户可以在任一终端上打开预先安装的浏览器程序，然后可以在浏览器程序的输入框中输入目标网页的网址。之后，浏览器程序可以基于用户输入的网址，发起对该目标网页的访问请求(可称为第一访问请求)。进而终端可以将该第一访问请求发送至服务终端的边缘服务器。这样，边缘服务器可以接收到终端对目标网页的第一访问请求，然后，边缘服务器可以根据该第一请求获取目标网页的网页内容。具体的，上述网页内容可以是HTML(HyperText Markup Language，超 级文本标记语言)内容，HTML内容中可以包括网页代码和标记图片、视频等资源的各类标签，例如link(链接)标签、script(脚本)标签、img(图片)标签等，每个标签的src(source，资源)属性或href(Hypertext Reference，指定超链接目标)属性可以记录有相应资源的URL，通过访问该URL可以获取到对应的资源。
步骤202：基于预设加密算法将网页内容中的各级URL改写为相应的防屏蔽URL，并将改写后的网页内容返回至终端。
在实施中，首先对广告屏蔽插件对广告类URL进行屏蔽的原理进行说明：当浏览器发起对某一URL的访问请求时，广告屏蔽插件可以结合记录有各种广告类URL关键词的屏蔽规则库，以字符为单位对上述访问请求中的URL进行识别，如果识别出屏蔽规则库记录的广告类URL关键词，则广告屏蔽插件可以对上述访问请求进行拦截处理，如果未识别出屏蔽规则库记录的广告类URL关键词，则广告屏蔽插件可以允许浏览器对该URL进行访问。
基于上述广告屏蔽插件对广告类URL进行屏蔽的原理，边缘服务器在获取目标网页的网页内容后，可以基于预设加密算法对网页内容中的各级URL进行加密，例如将各级URL中的广告类URL关键词进行编码混淆，生成相应的防屏蔽URL，以达到无法被广告屏蔽插件识别的目的。其中，网页内容中的各级URL可以包括一级URL和多级URL，一级URL可以是网页内容中记录的URL，例如上述标签的src属性或href属性记录的URL；多级URL可以是由网页内容中的网页脚本记录的URL，该URL通常记录在网页脚本的脚本内容中，并未在网页内容中进行记录，网页脚本可以是网站提供商添加的前端脚本或广告联盟脚本，网页脚本在运行时可以调用浏览器对网页脚本中记录的URL(即多级URL)进行访问。之后，边缘服务器可以将改写后的网页内容返回至终端。需要说明的是，上述预设加密算法可以是常见的加密算法，例如DES(Data Encryptin Standard，对称加密标准)算法、AES(Advanced Encryptin Standard，高级加密标准)算法，上述预设加密算法也可以是自定义的加密算法。
可选的，在一实施例中，可以通过广告防屏蔽脚本，在终端处对各级URL中的多级URL进行改写，相应的，步骤202的部分处理可以如下：基于预设加密算法将网页内容中的一级URL改写为相应的防屏蔽URL；以及，在网页内容中添加广告防屏蔽脚本，以使广告防屏蔽脚本检测到网页脚本发起对多级URL 的第三访问请求时，基于预设加密算法在第三访问请求中将多级URL改写为相应的防屏蔽URL。
其中，各级URL包括在网页内容中记录的一级URL和由网页内容中的网页脚本记录的多级URL。
在实施中，对于一级URL，由于其预先由网站提供商配置而记录在网页内容中，因此边缘服务器在获取到目标网页的网页内容时，可以直接对一级URL进行改写。而对于多级URL，其没有记录在网页内容中，而是当浏览器加载网页内容中的网页脚本后，由网页脚本进行获取，之后，才可以对多级URL进行改写。以网页脚本为广告联盟脚本为例，目标网页的广告可以由广告联盟提供，网站提供商只需将广告联盟开发的广告联盟脚本的URL添加在网页内容中即可完成广告接入，当浏览器访问网页内容中记录的广告联盟脚本的URL时，可以从广告联盟的相应服务器处获取并运行上述广告联盟脚本，之后，广告联盟脚本可以基于脚本内容中预先记录的广告类的多级URL，发起对广告类的多级URL的访问请求，调用浏览器获取相应的广告类资源，以完成广告的加载。这样，基于上述多级URL加载的滞后性，边缘服务器可以在网页内容中添加广告防屏蔽脚本，以对上述多级URL进行改写，该广告防屏蔽脚本可以检测到网页脚本发起的对脚本内容中记录的多级URL的第三访问请求，并可以在网页脚本调用浏览器获取上述多级URL对应的相应资源之前，对多级URL进行改写。具体的，对于一级URL，边缘服务器可以基于预设加密算法，将网页内容中的一级URL改写为相应的防屏蔽URL。对于多级URL，边缘服务器可以在网页内容中添加广告防屏蔽脚本，然后将添加有广告防屏蔽脚本的网页内容返回给终端。这样，当终端的浏览器加载上述网页内容中的广告防屏蔽脚本时，广告防屏蔽脚本可以对网页脚本是否发起对脚本内容中记录的多级URL的第三访问请求进行检测，当检测到网页脚本发起对上述多级URL的第三访问请求时，广告防屏蔽脚本可以基于预设加密算法，在第三访问请求中将多级URL改写为相应的防屏蔽URL，然后网页脚本可以调用浏览器对该防屏蔽URL进行访问，这样，浏览器的防屏蔽插件将无法识别出防屏蔽URL是否为广告类URL，进而浏览器可以正常访问该防屏蔽URL。
可选的，可以选择性的对广告类的多级URL进行改写，相应的处理可以如下：当广告防屏蔽脚本检测到网页脚本发起对多级URL的第三访问请求时，基 于预设屏蔽规则库，判断多级URL是否为屏蔽URL；如果是，则基于预设加密算法在第三访问请求中将多级URL中的广告类URL关键词进行编码混淆，生成相应的防屏蔽URL。
在实施中，除了广告类URL，网页内容中的各级URL还包括数量更多的非广告类URL，如果对所有的各级URL均进行改写，将会极大的消耗边缘服务器的处理资源，同时，也会降低边缘服务器进行广告防屏蔽的处理效率。这时，边缘服务器可以结合预设屏蔽规则库，例如广告屏蔽插件采用的通用屏蔽规则库，判断网页内容中的多级URL是否为广告类URL，即屏蔽URL，以决定是否进行对其进行改写。具体的，对于多级URL，广告防屏蔽脚本在检测到网页脚本发起对多级URL的第三访问请求时，广告防屏蔽脚本可以基于预设屏蔽规则库中的各个预设广告类URL关键词，判断多级URL中是否包含有预设广告类URL关键词，如果包含，则广告防屏蔽脚本可以判断该多级URL为屏蔽URL，进而广告防屏蔽脚本可以基于预设加密算法，在第三访问请求中将多级URL中的广告类URL关键词进行编码混淆，生成相应的防屏蔽URL；如果不是屏蔽URL，则广告防屏蔽脚本可以不对该多级URL进行改写，从而可以节省边缘服务器的系统资源，提高边缘服务器进行广告防屏蔽的处理效率，同时，也可以降低广告防屏蔽脚本对终端的安装环境等硬件要求，一些配置较低的终端也可以基于上述广告防屏蔽脚本取得较好的广告防屏蔽效果。
可选的，在另一实施例中，也可以在边缘服务器处对各级URL中的多级URL进行改写，相应的，步骤202的部分处理可以如下：基于预设加密算法将网页内容中的一级URL改写为相应的防屏蔽URL；以及，加载网页内容中的网页脚本，基于预设加密算法将网页脚本记录的多级URL改写为相应的防屏蔽URL。
其中，各级URL包括在网页内容中记录的一级URL和由网页内容中的网页脚本记录的多级URL。
在实施中，边缘服务器在获取到目标网页的网页内容后，对于网页内容中的一级URL，边缘服务器可以基于预设加密算法，将网页内容中的一级URL改写为相应的防屏蔽URL。同时，边缘服务器可以对网页内容中记录的各个网页脚本的一级URL进行访问，以加载这些网页脚本，之后，边缘服务器可以基于预设加密算法，将这些网页脚本的脚本内容中记录的多级URL改写为相应的防 屏蔽URL，并对这些改写后的网页脚本进行缓存。之后，边缘服务器可以将改写后的网页内容返回给终端。这样，当终端请求加载上述网页脚本时，边缘服务器可以将缓存的改写后的网页脚本发送给终端，进而改写后的网页脚本可以调用浏览器对改写后的脚本内容中的防屏蔽URL进行访问。
可选的，可以选择性的对广告类的多级URL进行改写，相应的处理可以如下：基于预设屏蔽规则库，判断网页脚本记录的多级URL是否为屏蔽URL；如果是，则基于预设加密算法将网页脚本记录的多级URL中的广告类URL关键词进行编码混淆，生成相应的防屏蔽URL。
在实施中，为了节省边缘服务器的系统资源，提供广告防屏蔽的处理效率，同样可以结合预设屏蔽规则库，在边缘服务器处对网页脚本记录的多级URL是否为屏蔽URL进行判断。具体的，边缘服务器在加载网页内容中的网页脚本后，可以基于预设屏蔽规则库中的各个预设广告类URL关键词，判断网页脚本记录的多级URL中是否包含有预设广告类URL关键词，如果包含，则边缘服务器可以判断该多级URL为屏蔽URL，进而边缘服务器可以基于预设加密算法，将网页脚本记录的多级URL中的广告类URL关键词进行编码混淆，生成相应的防屏蔽URL；如果不是屏蔽URL，则边缘服务器可以不对网页脚本记录的多级URL进行改写。
进一步的，对于一级URL，边缘服务器在获取到网页内容后，同样可以基于上述预设屏蔽规则库，判断网页内容中的一级URL是否为屏蔽URL；如果是屏蔽URL，则边缘服务器可以基于预设加密算法将网页内容中的一级URL中的广告类URL关键词进行编码混淆，生成相应的防屏蔽URL，如果不是屏蔽URL，则边缘服务器可以不对网页内容中的一级URL进行改写。
步骤203：当接收到终端对防屏蔽URL的第二访问请求时，基于预设解密算法将防屏蔽URL还原为相应的各级URL。
在实施中，终端在接收到边缘服务器发送的目标网页的网站内容后，可以依次对网站内容中的防屏蔽URL发起访问请求(可称为第二访问请求)。这样，当边缘服务器接收到终端发起的对防屏蔽URL的第二访问请求时，可以基于预设解密算法将防屏蔽URL还原为相应的各级URL，例如一级URL或多级URL。需要说明的是，为了将改写的防屏蔽URL进行还原，边缘服务器需要采用与上述预设加密算法相对应的预设解密算法，例如，当预设加密算法为DES算法时， 预设解密算法同样为DES算法。
步骤204：获取各级URL指向的资源，将资源返回至终端。
在实施中，边缘服务器在将防屏蔽URL还原为相应的各级URL后，可以对还原后的各级URL进行访问，获取其指向的资源，例如与广告相关的文字、图片或视频等资源。之后，边缘服务器可以将获取的上述资源返回给终端。这样，终端可以基于接收到的上述资源，在浏览器界面进行渲染展示。
在本实施例中，接收终端对目标网页的第一访问请求，获取目标网页的网页内容；基于预设加密算法将网页内容中的各级URL改写为相应的防屏蔽URL，并将改写后的网页内容返回至终端；当接收到终端对防屏蔽URL的第二访问请求时，基于预设解密算法将防屏蔽URL还原为相应的各级URL；获取各级URL指向的资源，将资源返回至终端。这样，可以利用边缘服务器或代理服务器能够对缓存的网页内容进行修改的特点，在接收到终端对网页的访问请求时，缓存服务器或代理服务器可以将网页内容中的各级URL，包括广告类URL，改写为广告屏蔽插件无法识别的URL，进而终端在后续对网页内容中的改写后的URL进行访问时，可以使得广告屏蔽插件失效，从而边缘服务器或代理服务器可以接收到上述改写后的URL，然后将改写后的URL还原为原始的各级URL，进而边缘服务器或代理服务器可以获取原始的各级URL所指向的资源，例如广告资源，并将其返还给终端，从而终端可以正常显示广告。另外，将上述广告防屏蔽的处理放在边缘服务器或代理服务器进行，可以无需修改网站提供商的网站原有的内部处理逻辑，有效降低网站提供商进行广告防屏蔽的成本。
