Description

网页图像的监控方法、装置、电子设备及计算机可读存储介质 技术领域
本公开涉及计算机技术领域，具体而言，本公开涉及一种网页图像的监控方法、装置、电子设备及计算机可读存储介质。
背景技术
随着互联网技术的高速发展，人们能够获取的信息也越来越多，单纯的文本形式信息已不能满足人们对信息的获取需求。由于图像形式的信息具有直观、表现力强等诸多优点，越来越受到人们的青睐。目前网页中包含的图像的比重越来越高，这也对浏览器的图像服务质量提出了更高要求。现有技术中无法有效监控网页页面中图像是否加载成功，也就无法实现基于图像是否加载成功实现对网页服务质量的分析。
发明内容
第一方面，提供了一种网页图像的监控方法，该方法包括：
当检测到网页页面的所有页面资源加载完成时，发送网页页面中的图像的查询请求；
获取查询请求的查询结果，基于查询结果，确定图像是否加载成功。
第二方面，提供了一种网页图像的监控装置，该装置包括：
查询请求发送模块，用于当检测到网页页面的所有页面资源加载完成时，发送网页页面中的图像的查询请求；
监控模块，用于获取查询请求的查询结果，基于查询结果，确定图像是否加载成功。
第三方面，提供了一种电子设备，该电子设备包括：处理器和存储器；
存储器，用于存储计算机程序；
处理器，用于通过调用计算机程序，执行如本公开的第一方面所示的 方法。
第四方面，提供了一种计算机可读存储介质，其上存储有计算机程序，该程序被处理器执行时实现本公开的第一方面所示的方法。
本公开实施例提供的技术方案带来的有益效果是：
通过在网页页面的所有页面资源加载完成时，发送网页页面中的图像的查询请求，获取查询请求的查询结果，基于查询结果确定图像是否加载成功。基于该方案，能够采用发起图像查询请求的方式获取到图像是否加载成功的信息，从而实现了对图像是否加载成功的监控，为基于图像是否加载成功实现对网页服务质量的分析、提升网页服务质量提供了数据支持。
附图说明
结合附图并参考以下具体实施方式，本公开各实施例的上述和其他特征、优点及方面将变得更加明显。贯穿附图中，相同或相似的附图标记表示相同或相似的元素。应当理解附图是示意性的，原件和元素不一定按照比例绘制。
为了更清楚地说明本公开实施例中的技术方案，下面将对本公开实施例描述中所需要使用的附图作简单地介绍。
图1为本公开实施例提供的一种网页图像的监控方法的流程示意图；
图2为本公开实施例提供的一种网页图像的监控装置的结构示意图；
图3为本公开实施例提供的一种电子设备的结构示意图。
具体实施方式
下面将参照附图更详细地描述本公开的实施例。虽然附图中显示了本公开的某些实施例，然而应当理解的是，本公开可以通过各种形式来实现，而且不应该被解释为限于这里阐述的实施例，相反提供这些实施例是为了更加透彻和完整地理解本公开。应当理解的是，本公开的附图及实施例仅用于示例性作用，并非用于限制本公开的保护范围。
应当理解，本公开的方法实施方式中记载的各个步骤可以按照不同的 顺序执行，和/或并行执行。此外，方法实施方式可以包括附加的步骤和/或省略执行示出的步骤。本公开的范围在此方面不受限制。
本文使用的术语“包括”及其变形是开放性包括，即“包括但不限于”。术语“基于”是“至少部分地基于”。术语“一个实施例”表示“至少一个实施例”；术语“另一实施例”表示“至少一个另外的实施例”；术语“一些实施例”表示“至少一些实施例”。其他术语的相关定义将在下文描述中给出。
需要注意，本公开中提及的“第一”、“第二”等概念仅用于对装置、模块或单元进行区分，并非用于限定这些装置、模块或单元一定为不同的装置、模块或单元，也并非用于限定这些装置、模块或单元所执行的功能的顺序或者相互依存关系。
需要注意，本公开中提及的“一个”、“多个”的修饰是示意性而非限制性的，本领域技术人员应当理解，除非在上下文另有明确指出，否则应该理解为“一个或多个”。
本公开实施方式中的多个装置之间所交互的消息或者信息的名称仅用于说明性的目的，而并不是用于对这些消息或信息的范围进行限制。
现有技术中一般采用软件开发工具包(Software Development Kit，SDK)来监控网页页面中图像是否加载成功。在实际使用中，业务方可能会为了保持业务原本的运行机制，将用于监控图像是否加载成功的SDK对应的代码放在网页的超文本标记语言(HyperText Markup Language，HTML)文件的主体(body)部分，由于图像的加载可能会较快，这便有可能会导致图像加载已经完成时，用于监控图像是否加载成功的SDK仍未运行，这时则无法获取到在上述SDK运行前已经加载完成图像的图像是否加载成功，造成信息监控的遗漏，无法实现对网页页面中图像是否加载成功的有效监控。
本公开实施例提供的网页图像的监控方法、装置、电子设备和计算机可读存储介质，旨在解决现有技术的如上技术问题中的至少一个。
下面以具体地实施例对本公开的技术方案以及本公开的技术方案如何解决上述技术问题进行详细说明。下面这几个具体的实施例可以相互结 合，对于相同或相似的概念或过程可能在某些实施例中不再赘述。下面将结合附图，对本公开的实施例进行描述。
图1示出了本公开实施例提供的一种网页图像的监控方法的流程示意图，如图1所示，该方法可以包括：
步骤S110：当检测到网页页面的所有页面资源加载完成时，发送网页页面中的图像的查询请求；
步骤S120：获取查询请求的查询结果，基于查询结果，确定图像是否加载成功。
本公开实施例中以浏览器加载网页页面为例，页面资源可以包括但是不限于网页页面内的字符、图像资源、视频资源等。
本公开实施例中，可以采用生成查询请求的方式来查询网页页面中的各图像对应的图像资源，查询请求中可以携带有图像的标识，便于对网页页面内的各图像进行区分。
本公开实施例中，若网页页面的图像资源加载成功，网页页面的图像资源缓存在浏览器缓存中，查询结果是基于浏览器缓存中的缓存内容确定的。
浏览器在加载时，遇到需要获取的页面资源(以图片资源为例)，浏览器或发出图片资源的获取请求来获取图片资源，当图片资源请求成功时，获取到的图片资源会被缓存至浏览器缓存中；而当图片资源请求失败时，浏览器缓存中则不会存储该图片资源。因此，可以通过发送查询请求，并在浏览器缓存内查询图像资源的方式，来确定图像是否加载成功。当在浏览器缓存中查找到了该图像对应的图像资源，则可以确定该图像加载成功；如果未在浏览器缓存中查找到该图像对应的图像资源，则可以确定该图像加载失败。
基于浏览器缓存机制，由于是在本地缓存内进行查询，可以快速的获得查询结果，无需通过网络向服务器进行数据请求，能够避免流量浪费。
本公开实施例中，是在检测到网页页面内所有图像加载完成时发送图像的查询请求，由于此时所有图像资源已经加载完成，因此，能够保证获取到所有查询请求的查询结果，从而监控页面内所有的图像是否加载成 功，避免造成监控遗漏。另外，浏览器会对各页面资源分别进行加载，浏览器在对页面资源的加载过程中，页面资源以图像为例，可能会出现一些图像已经加载结束时，另一些图像还未加载结束的情况，未加载结束的图像对应的图像资源不会被存储于本地缓存，这时如果在本地缓存内查询相应图像，则会造成查询结果的不准确，无法有效确定图像是否加载成功，因此，通过在网页页面的所有页面资源均加载完成后，发送网页页面中的图像的查询请求，能够保证获取的查询结果的准确性，以便能够准确确定出网页页面内的图像是否加载成功。
本公开实施例中，如果多次检测到网页中某些图像加载失败，则可以针对这些图像进行分析，确定导致加载失败的原因，并进行相应处理，以保证用户的使用体验。
本公开实施例提供的方法，通过在网页页面的所有页面资源加载完成时，发送网页页面中的图像的查询请求，获取查询请求的查询结果，基于查询结果确定图像是否加载成功。基于该方案，能够采用发起图像查询请求的方式获取到图像是否加载成功的信息，从而实现了对图像是否加载成功的监控，为基于图像是否加载成功实现对网页服务质量的分析、提升网页服务质量提供了数据支持。
本公开实施例的一种可选方式中，查询请求为可扩展标记语言超文本传输协议请求(XML HTTP Request)。
本公开实施例在实际使用中，查询请求可以为XML HTTP Request，查询请求中还可以携带有图像的属性信息所对应的请求参数，属性信息可以包括图像类型和/或图像大小。
本公开实施例中，当查询请求为XML HTTP Request时，如果图像加载成功，那么上述方法还可以包括：基于查询结果，提取图像的属性信息。
具体而言，查询请求为XML HTTP Request时，查询结果为查询指令的响应信息。响应信息的响应头中包含了图像的属性信息，实际使用中，可以通过正则表达式在响应信息中的响应头中提取图像的图像属性信息。
