背景技术
随着信息技术以及互联网技术的飞速发展，人们越来越多的通过互联网获取相关信息。通常，用户在使用互联网获取相关信息时，可以在互联网平台中输入想要搜索的目标对象，互联网平台可以根据用户输入的目标对象进行搜索，并将搜索得到的目标对象的相关信息展示给用户，这样，用户可以方便地获取到目标对象的相关信息。
为了使用户更好地获取目标对象的相关信息，互联网平台在将目标对象的相关信息展示给用户时，可以根据用户当前所在的地理位置信息，将距离用户较近的目标对象的相关信息展示给用户。具体地，首先，可以通过定位的方法确定用户当前所在的地理位置信息；其次，根据用户当前的地理位置信息确定距离用户较近的目标对象；最后，将确定的距离用户较近的目标对象的相关信息展示给用户。这样，用户可以方便地获取到距离自己较近的目标对象的相关信息。
通常，互联网平台在确定距离用户较近的目标对象时，可以将用户的地理位置信息与目标对象的地址信息进行匹配，并根据匹配结果确定目标对象。但是，由于匹配的准确度比较低，使得确定得到的目标对象的准确度比较低，导致为用户展示的目标对象的相关信息往往不能满足用户的实际需求，进而导致用户体验比较差。

具体实施方式
现有技术中，互联网平台在根据用户的地理位置信息，将距离用户较近的目标对象的相关信息展示给用户时，可以通过将用户的地理位置信息与目标对象的地址信息进行匹配，并根据匹配结果将目标对象的相关信息展示给用户，但是，由于匹配的准确度比较低，使得确定得到的目标对象的准确度比较低，例如，匹配得到的目标对象与用户之 间的实际距离比较远，使得用户确定目标对象的实际位置比较困难，进而导致用户体验比较差。
WIFI(英文全拼：Wireless Fidelity，中文名称：无线保真)是一种短距离、能够将个人电脑、手持设备(如Pad、手机)等终端以无线方式互相连接的无线网络传输技术。近年来，随着WIFI技术的飞速发展，WIFI技术越来越多地被应用在各种公共场所，例如，办公场所、消费场所等。通常，用户在某个公共场所需要通过WIFI访问互联网时，可以通过用户使用的用户设备搜索该公共场所对外提供的WIFI信号，用户设备在搜索到该WIFI信号后，可以显示该WIFI信号的名称，此时，用户设备可以连接至该WIFI信号。
这样，如果用户在公共场所使用用户设备连接至某个WIFI信号后，由于连接的WIFI信号为该公共场所提供，因此，可以根据连接的WIFI信号确定用户当前所在的是哪个公共场所，并且，由于WIFI信号的覆盖范围比较窄，根据WIFI信号确定的公共场所的准确度比较高。
由此可见，互联网平台在为用户展示目标对象的相关信息时，可以根据用户设备连接的WIFI信号，确定提供该WIFI信号的目标对象，由于根据WIFI信号确定的目标对象的准确度比较高，在将目标对象的相关信息展示给用户时，可以满足用户的实际需求。
在现有技术中，可以通过WIFI信号判断用户是否到达目标对象，进而为用户展示目标对象的相关信息，具体地，可以预先确定目标对象对应的WIFI信号的标识信息，这样，在用户设备监听到所述WIFI信号时，可以根据所述WIFI信号确定所述目标对象，并将所述目标对象的相关信息展示给用户。
但是，现有的方法在确定目标对象对应的WIFI信号的标识信息时，通常通过人为上传WIFI信号的标识信息的方式，或者，通过用户在目标对象内进行扫码支付时，获取用户设备连接的WIFI信号。针对人工上传WIFI信号的方法，获取WIFI信号的标识信息的效率比较低，并且，当目标对象更换WIFI信号时，目标对象的WIFI信号不能及时得到更新；针对获取用户交易时获取到的WIFI信号的方法，只能针对比较大的店铺，且只能针对安装有WIFI信号的目标对象，导致根据WIFI信号确定目标对象比较困难。
本申请实施例提供的技术方案，可以根据用户设备监听到的WIFI信号，将WIFI信号覆盖范围内的目标对象的相关信息展示给用户，使得提供给用户的目标对象的相关信息可以满足用户的实际需求，进而提升用户体验。
除此之外，本申请实施例提供的技术方案，无需用户人为上传目标对象对应的WIFI 信号的标识信息，并且，本申请实施例中确定的所述目标对象对应的WIFI信号可以是所述目标对象对外提供的WIFI信号，也可以是覆盖所述目标对象的其他WIFI信号，那么，只要目标对象可以接收到WIFI信号，在根据WIFI信号确定目标对象时，就可以通过覆盖目标对象的WIFI信号确定目标对象，进而避免上述存在的问题。
为了实现本申请的目的，本申请实施例中提供了一种信息推送方法、位置定位方法和设备，获取用户设备监听到的WIFI信号的特征信息，所述特征信息中包含所述WIFI信号的标识信息；从数据库中查找与所述WIFI信号的标识信息对应的目标对象的标识信息，所述数据库中包含所述WIFI信号的标识信息与所述WIFI信号覆盖范围内的目标对象的标识信息之间的映射关系；将查找到的所述目标对象的标识信息推送给所述用户设备。
根据用户设备当前可以监听到的WIFI信号的特征信息，确定所述WIFI信号覆盖范围内的目标对象的标识信息，并将确定的目标对象的标识信息推送给所述用户设备，使得使用所述用户设备的用户可以快速获取到目标对象的标识信息，并且，由于WIFI信号的覆盖范围较窄，基于WIFI信号确定的目标对象的准确性较高，使得为用户展示的目标对象的相关信息能够满足用户的实际需求，进而有效提升用户体验。
需要说明的是，在本申请实施例中，所述目标对象可以是店铺，本申请实施例提供的技术方案可以用于确定用户当前所在的店铺，并将该店铺的相关信息展示给用户，也可以用于确定用户所在位置附近的店铺，并将确定的用户附近的店铺的相关信息展示给用户，这里不做具体限定。
下面结合本申请具体实施例及相应的附图对本申请技术方案进行清楚、完整地描述。显然，所描述的实施例仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
以下结合附图，详细说明本申请各实施例提供的技术方案。
实施例1
图1为本申请实施例提供的一种信息推送方法的流程示意图，所述方法如下所述。
步骤101：获取用户设备监听到的WIFI信号的特征信息。
其中，所述特征信息中包含所述WIFI信号的标识信息。
在步骤101中，用户可以通过正在使用的用户设备监听覆盖用户设备的至少一个WIFI信号，此时，可以根据用户设备监听到的WIFI信号，获取所述WIFI信号的特征 信息。
所述用户设备指的是可以监听WIFI信号的设备，在本申请实施例中，所述用户设备可以是智能终端设备，例如，智能手机、笔记本电脑、iPad，还可以是其他可以监听WIFI信号的设备，不做具体限定。
用户在使用用户设备时，可以打开用户设备中用于监听WIFI信号的功能控件，此时，用户设备可以监听覆盖用户设备的WIFI信号，在监听到WIFI信号后，可以将监听到的WIFI信号对应的WIFI名称显示在用户设备中。这里的WIFI名称指的发射所述WIFI信号的设备(如无线路由器)的名称，在实际应用中，WIFI名称可以人为设置。
例如，用户设备可以监听到覆盖用户设备的、WIFI名称为“XXXX”的WIFI信号，那么，用户设备在监听到该WIFI名称对应的WIFI信号时，可以将该WIFI信号对应的WIFI名称“XXXX”显示在用户设备中。
在实际应用中，覆盖用户设备的WIFI信号的个数可以是一个，也可以是多个，如果覆盖用户设备的WIFI信号的个数是多个，那么，用户设备在监听到多个WIFI信号后，可以将监听到的每一个WIFI信号对应的WIFI名称显示在用户设备中。
在将监听到的WIFI信号对应的WIFI名称显示在用户设备之后，可以根据用户设备中显示的WIFI名称，获取所述WIFI信号的特征信息，其中，所述WIFI信号的特征信息可以包含所述WIFI信号的标识信息。
在本申请实施例中，所述WIFI信号的标识信息可以是所述WIFI信号对应的MAC(英文全拼：Media Access Control，中文名称：媒体访问控制)地址，也可以是所述WIFI信号对应的WIFI名称，不做具体限定。优选地，所述WIFI信号的标识信息为所述WIFI信号对应的MAC地址。
可选地，所述WIFI信号的特征信息还可以包含所述WIFI信号的信号强度，这里的所述WIFI信号的信号强度指的是所述用户设备在监听到所述WIFI信号时，所述用户设备可以接收到的所述WIFI信号的信号强度。
所述用户设备在监听到所述WIFI信号后，服务器可以获取到所述WIFI信号的特征信息。
具体地，所述服务器至少可以通过以下几种方式获取所述用户设备监听到的所述WIFI信号的特征信息：
第一种方式：所述用户设备在监听到所述WIFI信号，且确定与服务器建立数据连接时，可以将监听到的所述WIFI信号的特征信息发送给所述服务器，这样，所述服务 器可以获取到所述WIFI信号的特征信息。
所述用户设备可以在监听所述WIFI信号之前，建立与所述服务器之间的数据连接，也可以在监听到所述WIFI信号时，建立与所述服务器之间的数据连接，不做具体限定。
第二种方式：可以预先建立发射WIFI信号的设备(如无线路由器)与所述服务器之间的数据连接，这样，发射所述WIFI信号的设备在确定所述用户设备监听到所述WIFI信号时，可以确定所述用户设备监听到的所述WIFI信号的特征信息，并将所述WIFI信号的特征信息和所述用户设备的设备标识发送给所述服务器，这样，所述服务器可以获取到所述用户设备监听到的所述WIFI信号的特征信息。
在本申请实施例中，所述服务器可以是应用软件对应的服务器。所述服务器还可以通过其他方式获取所述用户设备监听到的所述WIFI信号的特征信息，不做具体限定。
这样，基于上述记载的方法，服务器可以获取到所述用户设备监听到的WIFI信号的特征信息。
步骤102：从数据库中查找与所述WIFI信号的标识信息对应的目标对象的标识信息。
其中，所述数据库中包含所述WIFI信号的标识信息与所述WIFI信号覆盖范围内的目标对象的标识信息之间的映射关系。
在步骤102中，在获取到WIFI信号的特征信息后，可以根据所述特征信息中包含的所述WIFI信号的标识信息，从数据库中查找与所述WIFI信号的标识信息对应的目标对象的标识信息，以便于将查找到的目标对象的标识信息推送给用户设备。
在本申请实施例中，所述数据库中可以预先存储所述WIFI信号的标识信息与所述WIFI信号覆盖范围内的目标对象的标识信息之间的映射关系，这样，在获取到的所述WIFI信号的标识信息时，可以根据所述WIFI信号的标识信息，从所述数据库中查找与所述WIFI信号的标识信息对应的目标对象的标识信息。
具体地，可以通过以下方式确定得到所述数据库：
第一步：获取覆盖目标对象的WIFI信号的特征信息，所述WIFI信号的特征信息携带在用户发送的业务请求中，所述WIFI信号的特征信息中包含所述WIFI信号的标识信息以及所述WIFI信号的信号强度，所述业务请求中包含所述目标对象的标识信息。
在实际应用中，用户在目标对象的位置处，可以使用用户设备监听WIFI信号，由于用户位于目标对象处，因此，用户设备监听到的WIFI信号为覆盖目标对象的WIFI信号，此时，所述用户可以通过WIFI信号访问互联网，并向服务器发送与目标对象相关的业务请求，所述业务请求中可以包含所述目标对象的标识信息，还可以包含所述用户 设备连接的覆盖所述目标对象的WIFI信号的特征信息。
所述特征信息中可以包含所述WIFI信号的标识信息，也可以包含所述WIFI信号的信号强度，这里的所述WIFI信号的信号强度指的是，所述用户在发送所述业务请求时，所述用户设备接收到的所述WIFI信号的信号强度。
这里的用户设备监听到的WIFI信号(即覆盖目标对象的WIFI信号)，可以是目标对象对外提供的WIFI信号，也可以是目标对象可以接收到的其他WIFI信号(即覆盖目标对象的其他WIFI信号)，不做具体限定。覆盖目标对象的WIFI信号可以是一个，也可以是多个，在本申请实施例中，用户设备可以连接至其中一个WIFI信号，并在所述用户发送业务请求时，将连接的所述WIFI信号的特征信息携带在所述业务请求中，也可以在所述用户发送业务请求时，将覆盖所述目标对象的多个WIFI信号的特征信息携带在业务请求中，不做具体限定。
可选地，在获取到WIFI信号的特征信息后，可以对获取到的WIFI信号进行筛选，排除其中的异常WIFI信号，例如，MAC地址异常的WIFI信号(例如，MAC地址为“00”)，WIFI名称异常的WIFI信号(例如，WIFI名称为“-”)，除此之外，还可以设定WIFI信号的强度范围，并排除信号强度不在设定范围内的WIFI信号，这里的WIFI信号的强度范围可以人为设定，优选地，所述强度范围可以是0db至-120db。
第二步：建立所述目标对象的标识信息、覆盖所述目标对象的WIFI信号的标识信息以及WIFI信号的信号强度之间的映射关系，并将所述映射关系存储至数据库中。
在获取到覆盖所述目标对象的WIFI信号的特征信息后，可以建立所述目标对象的标识信息、覆盖所述目标对象的WIFI信号的标识信息以及WIFI信号的信号强度之间的映射关系。
在实际应用中，针对一个目标对象，当多个不同用户设备在连接至覆盖所述目标对象的WIFI信号时，接收不同用户设备发送的业务请求，并从接收到的业务请求中获取用户设备所使用的WIFI信号的特征信息，这样，可以根据获取的WIFI信号的特征信息，建立所述目标对象的标识信息、覆盖所述目标对象的WIFI信号的标识信息以及WIFI信号的信号强度之间的映射关系。
具体地，由于在实际应用中，基于该目标对象，获取到的WIFI信号的个数可能是一个，也可能是多个，因此，在建立所述映射关系时，可以分别针对上述两种情况进行分析：
第一种情况：基于该目标对象，获取到的WIFI信号的个数为一个。
在建立所述映射关系时，需要确定所述WIFI信号的标识信息，所述目标对象的标识信息以及所述WIFI信号的信号强度，其中，所述目标对象的标识信息可以根据所述用户发送的业务请求确定得到，所述WIFI信号的标识信息可以根据所述WIFI信号确定得到。
在确定所述WIFI信号的信号强度时，由于在实际应用中，每一个用户设备监听到的所述WIFI信号的信号强度可能存在差异，因此，可以计算监听到的所述WIFI信号的不同信号强度的平均值，并将计算得到的平均值作为所述WIFI信号的信号强度。
可选地，还可以根据实际情况，确定所述WIFI信号的信号强度，这里不做具体限定。
在确定所述WIFI信号的信号强度后，可以建立所述目标对象的标识信息、覆盖所述目标对象的WIFI信号的标识信息以及WIFI信号的信号强度之间的映射关系。
第二种情况：基于该目标对象，获取到的WIFI信号的个数为多个。
在这种情况下，可以根据上述第一种情况中记载的方法确定所述多个WIFI信号的标识信息以及所述目标对象的标识信息，这里不再重复描述。
在确定所述多个WIFI信号的信号强度时，可以根据上述第一种情况中记载的方法，确定每一个所述WIFI信号的信号强度，这里不再重复描述。
在确定每一个WIFI信号的信号强度后，可以建立所述目标对象的标识信息、覆盖所述目标对象的WIFI信号的标识信息以及WIFI信号的信号强度之间的映射关系。
可选地，针对上述第二种情况，基于该目标对象，如果获取到的WIFI信号的个数为多个，可以对获取到的多个WIFI信号进行筛选，并选择至少一个WIFI信号，建立所述目标对象的标识信息、选择的WIFI信号的标识信息以及选择的WIFI信号的信号强度之间的映射关系。
具体地，在对获取到的多个WIFI信号进行筛选时，基于该目标对象，可以统计多个WIFI信号被不同用户设备监听到的次数，并根据统计得到的次数对获取到的多个WIFI信号进行筛选。
例如，基于该目标对象，获取到的WIFI信号包含WIFI信号A、WIFI信号B、WIFI信号C、WIFI信号D和WIFI信号E，其中，用户设备a可以监听到WIFI信号A、WIFI信号B和WIFI信号C，用户设备b可以监听到WIFI信号B、WIFI信号C和WIFI信号D，用户设备c可以监听到WIFI信号B、WIFI信号D和WIFI信号E，用户设备d可以监听到WIFI信号B和WIFI信号C。
可以统计得到，WIFI信号A被不同用户设备监听到的次数为1次，WIFI信号B被不同用户设备监听到的次数为4次，WIFI信号C被不同用户设备监听到的次数为3次，WIFI信号D被不同用户设备监听到的次数为2次，WIFI信号E被不同用户设备监听到的次数为1次，此时，可以按照被用户设备监听到的次数的大小顺序将上述5个WIFI信号进行排序，排序结果为：WIFI信号B、WIFI信号C、WIFI信号D、WIFI信号A/WIFI信号E。
那么，在对上述5个WIFI信号进行筛选时，可以选择被不同用户设备监听到的次数最多的WIFI信息B，也可以按照被不同用户设备监听到的次数的大小顺序，选择设定个数的WIFI信号，所述设定个数可以根据实际情况确定，例如，设定个数是2个时，可以选择WIFI信号B和WIFI信号C，设定个数是3个时，可以选择WIFI信号B、WIFI信号C和WIFI信号D。
除此之外，在本申请实施例中，在获取到的WIFI信号的个数为多个时，还可以根据实际情况对多个WIFI信号进行筛选，这里不做具体限定。
在筛选得到至少一个WIFI信号后，可以建立目标对象的标识信息、选择的至少一个WIFI信号的标识信息以及选择的至少一个WIFI信号的信号强度之间的映射关系。
仍以上述WIFI信号A、WIFI信号B、WIFI信号C、WIFI信号D和WIFI信号E为例，如果筛选得到WIFI信号B，那么，可以建立该目标对象的标识信息、WIFI信息B的标识信息以及WIFI信号B的信号强度之间的映射关系；如果筛选得到WIFI信号B和WIFI信号C，那么，可以建立该目标对象的标识信息、WIFI信号B的标识信息、WIFI信号C的标识信息以及WIFI信号B的信号强度、WIFI信号C的信号强度之间的映射关系。
这样，针对一个目标对象而言，可以得到所述目标对象的标识信息、覆盖所述目标对象的WIFI信号的标识信息以及WIFI信号的信号强度之间的映射关系，针对多个目标对象而言，可以通过上述记载的方法，得到每一个目标对象的标识信息、覆盖该目标对象的至少一个WIFI信号的标识信息以及所述至少一个WIFI信号的信号强度之间的映射关系。
这样，针对其中一个WIFI信号而言，可以基于上述方法得到的所述映射关系，确定所述WIFI信号的标识信息、所述WIFI信号覆盖范围内的至少一个目标对象的标识信息以及所述目标对象接收到的所述WIFI信号的信号强度之间的映射关系。
在得到所述映射关系后，可以将所述映射关系存储至数据库中。
这样，在根据所述用户设备监听到的WIFI信号的标识信息，从所述数据库中查找与所述WIFI信号的标识信息对应的目标对象的标识信息时，可以将所述WIFI信息的标识信息与所述数据库中存储的映射关系中包含的WIFI信号的标识信息进行匹配，得到包含所述WIFI信号的标识信息的映射关系，并根据得到的映射关系，确定与所述WIFI信号的标识信息建立映射关系的目标对象的标识信息。
在将所述WIFI信息的标识信息与所述数据库中存储的映射关系中包含的WIFI信号的标识信息进行匹配时，所述映射关系可以是上述记载的WIFI信号的标识信息、所述WIFI信号覆盖范围内的至少一个目标对象的标识信息以及所述目标对象接收到的所述WIFI信号的信号强度之间的映射关系，也可以是上述记载的每一个目标对象的标识信息、覆盖该目标对象的至少一个WIFI信号的标识信息以及所述至少一个WIFI信号的信号强度之间的映射关系，不做具体限定。
这样，可以查找得到与所述用户设备监听到的所述WIFI信号的标识信息对应的目标对象的标识信息。
步骤103：将查找到的所述目标对象的标识信息推送给所述用户设备。
在步骤103中，在查找到与WIFI信号的标识信息对应的目标对象的标识信息时，可以将所述目标对象的标识信息推送给所述用户设备，以便于使用所述用户设备的用户可以方便地查看到所述目标对象的标识信息。
基于上述步骤102中记载的方法，可以根据所述WIFI信号的标识信息查找得到所述WIFI信号覆盖范围内的目标对象的标识信息，在查找到目标对象的标识信息时，可以将所述目标对象的标识信息推送给所述用户设备。
但是，在实际应用中，由于用户设备监听到的所述WIFI信号的个数可以是一个，也可以是多个，并且，针对每一个WIFI信号而言，查找到的与所述WIFI信号的标识信息对应的目标对象的个数可以是一个，也可以是多个，因此，在将目标对象的标识信息推送给所述用户设备时，如果查找到的目标对象的个数是一个，那么，可以将该目标对象的标识信息推荐给所述用户设备；如果查找到的目标对象的个数是多个，那么，可以将多个目标对象的标识信息推送给所述用户设备，也可以对多个目标对象进行筛选，并将筛选得到的至少一个目标对象的标识信息推送给所述用户设备。
具体地，在本申请实施例中，在根据监听到的所述WIFI信号的标识信息，从所述数据库中查找目标对象的标识信息，至少存在以下几种情况：
第一种情况：所述WIFI信号的个数为一个，查找到的所述目标对象的个数为一个；
第二种情况：所述WIFI信号的个数为一个，查找到的所述目标对象的个数为多个；
第三种情况：所述WIFI信号的个数为多个，查找到的所述目标对象的个数为一个；
第四种情况：所述WIFI信号的个数为多个，查找到的所述目标对象的个数为多个。
下面，分别针对上述四种情况进行分析，说明如何将查找得到的目标对象的标识信息推送给所述用户设备。
针对第一种情况：
在所述WIFI信号的个数为一个时，查找到的所述目标对象的个数也为一个，此时，可以将所述目标对象的标识信息推送给所述用户设备。
针对第二种情况：
在所述WIFI信号的个数为一个，查找到的所述目标对象的个数为多个时，可以选择其中至少一个目标对象，并将选择的目标对象的标识信息推送给使用所述用户设备的用户。
具体地，将查找到的所述目标对象的标识信息推送给所述用户设备，包括：
在确定查找到的所述目标对象的个数大于1时，确定所述用户设备监听到的所述WIFI信号的第一信号强度；

此时，可以根据查找到的多个目标对象的标识信息，从上述记载的所述数据库中查找与每一个所述目标对象的标识信息对应的所述WIFI信号的信号强度。
在本申请实施例中，为了便于区别，可以将所述用户设备监听到的所述WIFI信号的信号强度称为所述WIFI信号的第一信号强度，从所述数据库中查找到的所述WIFI信号的信号强度称为所述WIFI信号的第二信号强度。
在确定所述WIFI信号的第一信号强度和所述WIFI信号的第二信号强度后，可以根据所述WIFI信号的第一信号强度和所述WIFI信号的第二信号强度，选择至少一个所述 目标对象。

其中，λ为所述目标对象的特征值，s1为所述WIFI信号的第一信号强度，s2为所述目标对象接收到的所述WIFI信号的第二信号强度，a和b为设定参数。
在本申请实施例中，a和b可以用来限定目标对象的特征值的取值范围，a和b的取值可以根据实际情况确定，优选地，a可以是1，b可以是1。
通过上述记载的公式，可以得到每一个所述目标对象的特征值。
可选地，在本申请实施例中，还可以通过其他方式确定得到每一个所述目标对象的特征值，这里不做具体限定。
例如，针对其中一个目标对象，可以计算所述WIFI信号的第一信号强度与所述目标对象接收到的所述WIFI信号的第二信号强度之间的差值的绝对值，并将计算得到的差值的绝对值作为所述目标对象的特征值。
在得到每一个所述目标对象的特征值后，可以根据所述特征值，选择至少一个所述目标对象。
具体地，可以按照所述特征值从小到大的顺序，将至少一个所述目标对象进行排序，也可以按照所述特征值从大到小的顺序，将至少一个所述目标对象进行排序，这里不做具体限定。
在对至少一个所述目标对象排序后，可以根据排序结果，选择至少一个目标对象。
需要说明的是，从上述记载的公式可以看出，所述WIFI信号的第一信号强度与所 述目标对象接收到的所述WIFI信号的第二信号强度之间的差值越小，所述目标对象的特征值越大，在实际应用中，所述WIFI信号的第一信号强度与所述WIFI信号的第二信号强度之间的差值越小，可以说明，所述用户设备与所述目标对象之间的距离越近，因此，在根据排序结果，选择至少一个目标对象时，可以按照目标对象的特征值从大到小的顺序，选择特征值大于设定阈值的至少一个目标对象，这里的设定阈值可以根据实际情况确定。
可选地，针对上述记载的，将所述WIFI信号的第一信号强度与所述目标对象接收到的所述WIFI信号的第二信号强度之间的差值的绝对值，作为所述目标对象的特征值的情况，所述WIFI信号的第一信号强度与所述目标对象接收到的所述WIFI信号的第二信号强度之间的差值越小，所述目标对象的特征值越小，在实际应用中，可以说明所述用户设备与所述目标对象之间的距离越近，此时，在根据排序结果，选择至少一个目标对象时，可以选择特征值小于设定阈值的至少一个目标对象，这里的设定阈值也可以根据实际情况确定。
在本申请实施例中，还可以根据实际情况选择至少一个目标对象，这里不做具体限定。
针对第三种情况：
在所述WIFI信号的个数为多个，查找到的所述目标对象的个数为一个时，可以将所述目标对象的标识信息推送给所述用户设备。
针对第四种情况：
在所述WIFI信号的个数为多个，查找到的所述目标对象的个数也为多个时，可以选择至少一个所述目标对象，并将选择的目标对象的标识信息推送给所述用户设备。
具体地，在选择至少一个所述目标对象时，可以根据上述第二种情况中记载的方法确定用户设备监听到的每一个所述WIFI信号的第一信号强度，以及查找每一个所述目标对象接收到的所述WIFI信号的第二信号强度，这里不再重复描述。
在确定监听到的每一个所述WIFI信号的第一信号强度以及每一个所述目标对象接收到的所述WIFI信号的第二信号强度后，可以计算得到每一个所述目标对象的特征值。
具体地，至少可以通过以下几种方法计算得到每一个所述目标对象的特征值，包括：
第一种方法：
可以通过以下公式计算得到每一个所述目标对象的特征值：
Figure PCTCN2017087134-appb-000002
其中，λj为目标对象j的特征值，m为所述用户设备监听到的WIFI信号的个数，i的取值范围为[1，m]，j为所述目标对象的标识信息，sij为目标对象j接收到的第i个WIFI信号的第二信号强度，si为第i个WIFI信号的第一信号强度，a和b为设定参数。
在本申请实施例中，a和b可以用来限定目标对象的特征值的取值范围，a和b的取值可以根据实际情况确定，优选地，a可以是1，b可以是1。
在实际应用中，针对一个目标对象而言，如果目标对象可以接收到的WIFI信号的个数越多(这里的WIFI信号为用户设备监听到的WIFI信号)，可以说明，目标对象与用户设备之间的距离越近；针对目标对象接收到的其中一个WIFI信号而言，用户设备监听到的所述WIFI信号的第一信号强度与目标对象接收到的所述WIFI信号的第二信号强度越接近，用户设备与目标对象之间的位置越接近，从公式中可以看出，目标对象的特征值越大。
因此，在计算目标对象的特征值时，如果目标对象可以接收到的WIFI信号的个数为多个，那么，在计算目标对象的特征值时，可以将每一个WIFI信号对应的目标对象的特征值相加，这样，目标对象的特征值越大，可以说明，目标对象与用户设备之间的距离越近。
如图2所示，用户设备监听到的WIFI信号的个数为2个，分别为WIFI信号A和WIFI信号B，其中，监听到的WIFI信号A的信号强度为sA，监听到的WIFI信号B的信号强度为sB。
根据WIFI信号A的标识信息，可以从所述数据库中查找到WIFI信号A覆盖范围内的目标对象为目标对象1、目标对象2、目标对象3，并且，从所述数据库中查找到目标对象1接收到的WIFI信号A的信号强度为sA1，目标对象2接收到的WIFI信号A的信号强度为sA2，目标对象3接收到的WIFI信号A的信号强度为sA3。
根据WIFI信号B的标识信息，可以从所述数据库中查找到WIFI信号B覆盖范围内的目标对象为目标对象2、目标对象3、目标对象4，并且，从所述数据库中查找到目标对象2接收到的WIFI信号B的信号强度为sB2，目标对象3接收到的WIFI信号B的信号强度为sB3，目标对象4接收到的WIFI信号B的信号强度为sB4。
根据上述记载的公式，可以分别计算得到目标对象1、目标对象2、目标对象3以及目标对象4的特征值，其中，设定参数a为1，设定参数b为1。
具体地，目标对象1的特征值为：
Figure PCTCN2017087134-appb-000003
目标对象2的特征值为：
Figure PCTCN2017087134-appb-000004
目标对象3的特征值为：
Figure PCTCN2017087134-appb-000005
目标对象4的特征值为：
Figure PCTCN2017087134-appb-000006
第二种方法：可以通过以下公式计算得到目标对象的特征值：
λj＝mj；
其中，λj为目标对象j的特征值，j为目标对象的标识信息，mj为目标对象j可以接收到的WIFI信号的个数，这里的WIFI信号指的是用户设备监听到的WIFI信号。
在实际应用中，针对一个目标对象而言，如果目标对象可以接收到的WIFI信号的个数越多(这里的WIFI信号为用户设备监听到的WIFI信号)，可以说明，目标对象与用户设备之间的距离越近，因此，在确定所述目标对象的特征值时，可以根据目标对象可以接收的WIFI信号的个数确定，从公式可以看出，目标对象接收到的WIFI信号的个数越多，目标对象的特征值越大。
例如，仍以上述图2为例，用户设备监听到的WIFI信号为WIFI信号A和WIFI信号B，可以确定，目标对象1可以接收到的WIFI信号的个数为1个，目标对象2可以接收到的WIFI信号的个数为2个，目标对象3可以接收到的WIFI信号的个数为2个，目标对象4可以接收到的WIFI信号的个数为1个，此时，可以确定目标对象1的特征值为1，目标对象2的特征值为2，目标对象3的特征值为2，目标对象4的特征值为1。
可选地，在本申请实施例中，还可以通过其他方法计算得到每一个所述目标对象的特征值，这里不做具体限定。
在得到每一个所述目标对象的特征值后，可以根据所述特征值，选择至少一个所述目标对象。
具体地，可以按照所述特征值从小到大的顺序，将至少一个所述目标对象进行排序，也可以按照所述特征值从大到小的顺序，将至少一个所述目标对象进行排序，这里不做具体限定。
在对至少一个所述目标对象排序后，可以根据排序结果，选择至少一个目标对象。
具体地，可以分别针对上述记载的两种方法，分别说明如何选择至少一个所述目标对象：
针对第一种方法：
从公式中可以看出，WIFI信号的第一信号强度与目标对象接收到的所述WIFI信号的第二信号强度之间的差值越小，目标对象接收到的WIFI信号的个数越多，目标对象的特征值越大，在实际应用中，WIFI信号的第一信号强度与目标对象接收到的所述WIFI信号的第二信号强度之间的差值越小，目标对象接收到的WIFI信号的个数越多，可以说明，用户设备与目标对象之间的距离越近，因此，在根据排序结果，选择至少一个目标对象时，可以按照目标对象的特征值从大到小的顺序，选择特征值大于设定阈值的至少一个目标对象，这里的设定阈值可以根据实际情况确定。
针对第二种方法：
从公式中可以看出，目标对象接收到的WIFI信号的个数越多，目标对象的特征值越大，在实际应用中，目标对象接收到的WIFI信号的个数越多，可以说明，用户设备与目标对象之间的距离越近，因此，在根据排序结果，选择至少一个目标对象时，可以按照目标对象的特征值从大到小的顺序，选择特征值大于设定阈值的至少一个目标对象，这里的设定阈值也可以根据实际情况确定。
在本申请实施例中，还可以根据实际情况选择至少一个目标对象，这里不做具体限定。
可选地，所述方法还包括：
根据所述目标对象的特征值，判断所述用户设备的位置是否与选择的所述目标对象的位置一致。
从上述记载的公式可以看出，所述WIFI信号的第一信号强度与所述WIFI信号的第二信号强度之间的差值越小，所述目标对象接收到的WIFI信号的个数越多，所述目标对象的特征值越大，而在实际应用中，所述第一信号强度与所述第二信号强度之间的差值越小，所述目标对象接收到的WIFI信号的个数越多，可以说明，所述用户设备与所述目标对象之间的距离越近，因此，在得到所述目标对象的特征值后，可以根据所述特征值判断所述用户设备的位置与选择的所述目标对象的位置是否一致。
具体地，可以根据所述目标对象的特征值，确定所述目标对象的特征值是否大于设定值，如果大于，可以说明所述用户设备与所述目标对象之间的距离比较近，也就是说，所述用户设备的位置与所述目标对象的位置一致。
这里的设定值可以根据实际情况确定，不做具体限定。
基于上述记载的四种情况，在确定所述目标对象的标识信息后，可以将所述目标对象的标识信息推送给所述用户设备，以便于使用所述用户设备的用户可以获取到所述目标对象的标识信息。
可选地，将所述目标对象的标识信息推送给所述用户设备，包括：
确定与所述目标对象相关的推送信息，并将所述推送信息推送给所述用户设备。
在将所述目标对象的标识信息推送给所述用户设备时，为了使使用所述用户设备的用户获取所述目标对象的更多的信息，还可以将与所述目标对象相关的推送信息共同推送给所述用户设备。
在本申请实施例中，与所述目标对象相关的推送信息可以是与所述目标对象相关的信息，例如，在所述目标对象是店铺时，所述推送信息可以是店铺内的商品的信息(如商品的价格，商品的销售信息等)，也可以是店铺的其他相关信息，这里不做具体限定。
将与所述目标对象相关的推送信息推送给所述用户设备后，使用所述用户设备的用户可以获取到更多的关于所述目标对象的信息。
在实际应用中，用户在获取到与目标对象相关的推送信息后，可以根据获取到的推送信息，向服务器发送与所述目标对象相关的业务请求，此时，服务器可以接收用户发送的业务请求。
可选地，所述方法还包括：
接收用户发送的业务请求，所述业务请求中包含目标对象的标识信息以及WIFI信号的特征信息，所述特征信息中包含所述WIFI信号的标识信息以及所述WIFI信号的信号强度；
根据所述业务请求中包含的所述WIFI信号的特征信息，更新所述数据库中存储的覆盖所述目标对象的WIFI信号的特征信息。
在用户发送所述业务请求后，服务器可以接收所述业务请求，所述业务请求中可以包含所述目标对象的标识信息，还可以包含WIFI信号的特征信息，所述特征信息中可以包含所述WIFI信号的标识信息以及所述WIFI信号的信号强度。
需要说明的是，所述WIFI信号可以是所述用户在发送业务请求时，所述用户使用的用户设备连接的WIFI信号，也可以所述用户设备监听到的至少一个WIFI信号，不做具体限定。
在获取到所述目标对象的特征信息以及所述WIFI信号的特征信息后，可以根据获 取到的所述WIFI信号的特征信息更新所述数据库中存储的与所述目标对象的标识信息对应的WIFI信号的特征信。
具体地，可以判断获取到的所述WIFI信号的特征信息与所述数据库中存储的覆盖所述目标对象的WIFI信号的特征信息是否一致，如果判断结果为不一致，那么，可以根据获取到的所述WIFI信号的特征信息，更新所述数据库中存储的覆盖所述目标对象的WIFI信号的特征信息。
本申请实施例提供的技术方案，根据用户设备当前可以监听到的WIFI信号的特征信息，确定所述WIFI信号覆盖范围内的目标对象的标识信息，并将确定的目标对象的标识信息推送给所述用户设备，使得使用所述用户设备的用户可以快速获取到目标对象的标识信息，并且，由于WIFI信号的覆盖范围较窄，基于WIFI信号确定的目标对象的准确性较高，使得为用户展示的目标对象的相关信息能够满足用户的实际需求，进而有效提升用户体验。
实施例2
下面以目标对象为店铺为例，说明如何通过本申请实施例提供的技术方案，确定与用户距离较近的店铺，并将店铺的标识信息推送给用户。
首先，确定店铺的标识信息、覆盖店铺的WIFI信号的标识信息以及覆盖店铺的所述WIFI信号的信号强度之间的映射关系。
这里的店铺的标识信息可以是店铺的名称。
具体地，用户位于店铺内时，可以使用用户设备连接至覆盖店铺的其中一个WIFI信号，此时，如果用户发送与店铺相关的业务请求，服务器可以获取用户发送业务请求时，用户设备连接的WIFI信号的特征信息，也可以获取用户发送业务请求时刻前后设定时间内，用户设备监听到的WIFI信号的特征信息，这里的设定时间可以是用户位于所述店铺内的任何一段时间，优选地，所述设定时间可以是1分钟，并获取用户交易时刻前后1分钟内，用户设备监听到的WIFI信号的特征信息。
这样，可以累积一个月内(或者两个月内，不做具体限定)，位于所述店铺的用户发送与店铺相关的业务请求时，用户设备连接的WIFI信号的特征信息(或用户设备监听到的WIFI信号的特征信息)，在得到大量的WIFI信号的特征信息后，可以对累积的WIFI信号的特征信息进行分析和处理。
可选地，可以排除WIFI信号的标识信息异常的WIFI信号，并筛选出信号强度在0db至-120db之间的WIFI信号。
在确定覆盖店铺的WIFI信号的标识信息时，如果WIFI信号的个数为多个，可以根据WIFI信号被不同用户设备监听的次数，选择次数较多的设定个数的WIFI信号，例如，如果WIFI信号的个数为二十个，可以选择被不同用户设备监听的次数排名前十的WIFI信号。
在确定每一个WIFI信号的信号强度时，可以计算每一个WIFI信号的信号强度的平均值，并将所述平均值作为WIFI信号的信号强度。
这样，可以建立店铺的标识信息、覆盖店铺的WIFI信号的标识信息以及覆盖店铺的所述WIFI信号的信号强度之间的映射关系。
针对其他店铺，可以通过上述记载的方法得到每一个店铺的标识信息、覆盖该店铺的WIFI信号的标识信息以及覆盖该店铺的WIFI信号的信号强度之间的映射关系。
这样，针对多个店铺而言，可以得到店铺的标识信息、覆盖店铺的WIFI信号的标识信息、覆盖店铺的WIFI信号的信号强度之间的映射关系，进一步地，针对一个WIFI信号而言，可以得到所述WIFI信号的标识信息、所述WIFI信号覆盖范围内的店铺的标识信息以及所述店铺接收到的所述WIFI信号的信号强度之间的映射关系。
在得到所述映射关系后，可以将所述映射关系存储至数据库中。
其次，根据用户设备当前监听到的WIFI信号的特征信息，为用户推送店铺信息。
具体地，可以根据用户设备监听到的WIFI信号的标识信息，从所述数据库中查找与WIFI信号的标识信息对应的店铺的标识信息。
此时，如果查找到的店铺的个数为一个，那么，可以将与所述一个店铺相关的推送信息推送给用户设备，如果查找到的店铺的个数为多个，那么，可以计算每个店铺的特征值，并根据计算得到的特征值，选择至少一个店铺，并将与选择的店铺相关的推送信息推送给用户设备，使得使用用户设备的用户可以根据推送的信息获取店铺的相关信息。
如图3所示，用户设备可以监听到的WIFI信号为WIFI-1和WIFI-3，用户设备监听到的WIFI-1的信号强度为-70db，WIFI-3的信号强度为-60db。
从数据库中可以查找到WIFI-1对应的店铺为店铺1、店铺2以及店铺3，查找到店铺1接收到的WIFI-1的信号强度为-30db，店铺2接收到的WIFI-1的信号强度为-60db，店铺3接收到的WIFI-1的信号强度为-100db。
从数据库中可以查找到WIFI-3对应的店铺为店铺1、店铺2以及店铺3，查找到店铺1接收到的WIFI-3的信号强度为-100db，店铺2接收到的WIFI-3的信号强度为-60db，店铺3接收到的WIFI-3的信号强度为-20db。
经过计算，可以得到店铺1的特征值为2.05，店铺2的特征值为3.09，店铺3的特征值为2.06，那么，此时，可以将与店铺2相关的推送信息推送给用户设备。
可选地，由于店铺1和店铺3也在WIFI-1和WIFI-3的覆盖范围内，因此，也可以将与店铺1相关的推送信息以及与店铺3相关的推送信息推送给用户设备，在将三个店铺的推送信息展示给用户时，可以按照店铺2、店铺3、店铺1的先后顺序进行展示。
可选地，由于店铺2的特征值最大，还可以确定用户当前的位置与店铺2的位置一致，即用户位于店铺2。
在将与店铺2相关的推送信息推送给用户设备时，用户设备中可以显示店铺2的相关信息，例如，店铺2中所有商品的价格信息和销售信息，这样，使用用户设备的用户可以快速获得店铺2的相关信息。
用户在获得店铺2的相关信息后，可以对店铺2中的商品进行消费，具体地，用户可以发送包含店铺2的标识信息的业务请求，所述业务请求中可以包含用户设备连接的WIFI信号的特征信息，此时，可以根据所述WIFI信号的特征信息以及店铺2的标识信息，更新上述记载的店铺的标识信息、覆盖店铺的WIFI信号的标识信息以及覆盖店铺的所述WIFI信号的信号强度之间的映射关系。
在实际应用中，可以根据用户设备监听到的WIFI信号的特征信息，确定用户是否到达某个店铺，如果判断结果是用户到达该店铺，那么，可以将该店铺的相关信息展示给用户，例如，在确定用户到达某个餐饮店铺时，可以将该餐饮店铺的餐饮信息展示给用户，此时，用户可以根据展示的餐饮信息进行点餐等；如果判断结果是用户没有到达该店铺，那么，可以为用户展示用户当前位置附近的店铺的相关信息。
除此之外，可以获取用户设备每天监听到的WIFI信号的特征信息，并根据获取的WIFI信号的特征信息，确定用户经常途径的店铺的标识信息以及途径该店铺的时间信息，这样，可以在特定时间段，为用户展示店铺的相关信息，例如，用户在每天的早上8点至9点都会途径店铺1，那么，可以在每天的8点之前，为用户推送店铺1的相关信息，这样，用户可以在8点至9点之间途径店铺1时，可以根据推送信息进行消费。

在得到所述WIFI信号的第一信号强度以及所述WIFI信号的第二信号强度后，可以根据上述步骤103中记载的方法，计算得到所述目标对象的特征值，这里不再重复描述。
步骤404：根据所述目标对象的特征值，判断所述用户设备的位置与所述目标对象的位置是否一致。
在步骤404中，在计算得到所述目标对象的特征值后，可以根据所述目标对象的特征值，判断所述用户设备的位置与所述目标对象的位置是否一致。
需要说明的是，在实际应用中，用户设备监听到的所述WIFI信号的个数可以是一个，也可以是多个，从所述数据库中查找到的目标对象的个数可以是一个，也可以是多个，那么，在查找到的所述目标对象的个数为一个时，可以说明所述用户设备以及所述 目标对象可以接收到所述WIFI信号，此时，可以确定所述用户设备的位置与所述目标对象的位置一致；在查找到的所述目标对象的个数是多个时，可以对多个目标对象进行筛选，并根据筛选后的目标对象的位置，确定所述用户设备的位置。
