【具体实施方式】
为了使本发明的目的、技术方案和优点更加清楚，下面结合附图和具体实施例对本发明进行详细描述。
为了方便对本发明的理解，首先对本发明所涉及的系统架构以及主要概念进行描述。如图1中所示，该系统架构主要包括宿主应用和宿主应用对应的服务器端。
小程序依托宿主应用在终端设备上运行，小程序运行所在的环境是宿主应用提供的。其中终端设备可以包括但不限于诸如：智能移动终端、智能家居设备、网络设备、可穿戴式设备、智能医疗设备、PC(个人计算机)等。其中智能移动设备可以包括诸如手机、平板电脑、笔记本电脑、PDA(个人数字助理)、互联网汽车等。智能家居设备可以包括智能家电设备，诸如智能电视、智能音箱等。网络设备可以包括诸如交换机、无线AP、服务器等。可穿戴式设备可以包括诸如智能手表、智能眼镜、智能手环、虚拟现实设备、增强现实设备、混合现实设备(即可以支持虚拟现实和增强现实的设备)等等。
同一终端设备上可能包含多个宿主应用，图1中以包含宿主应用1和宿主应用2为例。一个宿主应用中也可能运行多个小程序，且不同宿主应用可能运行不同的小程序，也可能运行相同的小程序。如图1中所示，宿主应用1中运 行小程序a和小程序b，宿主应用2中运行小程序b和小程序c。
每个宿主应用都存在对应的服务器端，如图1中所示，宿主应用1对应服务器端1，宿主应用2对应服务器端2。每个宿主应用均可以与其对应的服务器端进行交互，在本发明实施例中，不同的服务器端之间也可以进行数据交互。
各服务器端可以是单一服务器，也可以是多个服务器构成的服务器群组。应该理解，图1中的终端设备、宿主应用、小程序、服务器端的数目仅仅是示意性的。根据实现需要，可以具有任意数目的终端设备、宿主应用、小程序、服务器端。
本发明的核心思想在于，同一终端设备中各宿主应用共享下载的小程序的文件包来进行小程序的启动，从而实现解决小程序重复下载的问题，节约资源。图2为本发明实施例提供的主要方法流程图，该方法由终端设备的宿主应用执行，执行装置可以是位于终端设备宿主应用的插件或软件开发工具包(Software Development Kit，SDK)等功能单元。如图2所示，该方法主要包括以下步骤：
在201中，获取触发小程序启动的事件。
本发明并不限于在宿主应用中触发小程序启动的事件类型，例如可以是用户在宿主应用中点击小程序图标以触发小程序启动，也可以是用户在宿主应用中点击某链接触发对应小程序启动，等等。
在202中，确认终端设备中是否存在宿主应用存储有该小程序的文件包，如果是，执行203；否则，执行204。
由于小程序在宿主应用中无需安装，因此本发明实施例中涉及的小程序的文件包并非安装包，而是包含启动小程序以及运行小程序所需要的小程序文件，可以包括诸如：源文件、压缩后的代码、资源文件等等。
在203中，利用该小程序的文件包启动该小程序，结束流程。
如果在终端设备中已经有宿主应用存储有该小程序的文件包，则无需重复下载，直接利用已经存储的小程序的文件包启动小程序即可。
在204中，从服务器端下载并存储该小程序的文件包以启动该小程序，设置该小程序的文件包的存储位置其他宿主应用可读。
若终端设备中并没有宿主应用存储有该小程序的文件包，则需要从服务器端下载，并存储该小程序的文件包。为了下载的小程序的文件包也能够为其他 宿主应用所使用，除了本宿主应用可读该小程序包的存储位置之外，该存储位置对其他宿主应用也可读。
在本发明实施例中采用同一终端设备中宿主应用共享存储的小程序的文件包的方式，其中共享方式可以采用但不限于以下几种：
第一种方式：宿主应用将下载的小程序文件包存储于本宿主应用的私有目录下，设置该私有目录对其他宿主应用也可读。同时，宿主应用将存储小程序的文件包的状况上报至对应的服务器端，各宿主应用的服务器端会进行宿主应用存储小程序的文件包的状况同步，以供其他宿主应用均能够从对应的服务器端获取到同一终端设备中各宿主应用存储小程序的文件包的状况。
也就是说，第一种方式中，宿主应用将小程序文件包存储在本宿主应用的私有目录下，各宿主应用存储小程序文件包的状况在服务器端同步并从服务器端获取。
第二种方式：宿主应用将下载的小程序文件包存储于本宿主应用的私有目录下，设置该私有目录对其他宿主应用也可读。同时，宿主应用将存储小程序的文件包的状况记录于终端设备中的共享数据库。各宿主应用均能够从共享数据库中获知小程序文件包的存储状况。
第三种方式：宿主应用将下载的小程序文件包均存储于终端设备的共享存储空间，终端设备中各宿主应用均从该共享存储空间读取小程序文件包来进行小程序的启动。
下面将结合具体实施例对上述三种方式分别进行详细描述。另外，需要说明的是，一种理想的情况是，所有宿主应用均采用相同的小程序标准。但往往在实际情况中，一些宿主应用是采用相同的小程序标准的，但另一些宿主应用则采用其他小程序标准。那么可以将采用相同小程序标准的宿主应用称为一个宿主联盟。针对属于同一宿主联盟的各宿主应用采用本发明实施例所提供的共享小程序文件包的方式。关于哪些宿主应用属于同一宿主联盟则可以在服务器端统一配置，然后各宿主应用从服务器端获取。在下面的实施例中均以同一宿主联盟的各宿主应用共享小程序文件包的方式为例进行描述。另外，对于宿主联盟的所有宿主应用而言，所有小程序的文件包均采用统一的命名机制，以便通过小程序的文件包名就能够获知其对应的小程序。
实施例一、
图3为本发明实施例一提供的方法流程图，本实施例中对上述第一种实现方式进行描述。假设用户欲在宿主应用1中启动小程序c，如图3所示，由宿主应用1执行的方法可以包括以下过程：
在301中，宿主应用1启动时，从服务器端同步宿主联盟的信息并存储于宿主应用1本地的数据库。
宿主应用1在启动时，可以向对应服务器端发送宿主联盟的同步请求，对应服务器端向该宿主应用1返回宿主联盟的各宿主应用的信息，例如包名。然后宿主应用1可以确定本终端设备已经安装的宿主联盟的宿主应用信息。
当宿主应用1启动时，可以对所在终端设备本地已安装的应用程序进行扫描，再进一步利用从服务器端同步到的宿主联盟的信息，就能够确定出本终端设备已经安装的宿主联盟的宿主应用信息，可以将这些宿主应用的信息以列表形式存储于本宿主应用的数据库中。
举个例子，假设服务器端下发的宿主联盟的信息包括：宿主应用1、宿主应用2、宿主应用3、宿主应用4……。宿主应用1扫描本终端设备后发现本终端设备安装有宿主应用1和宿主应用2，那么宿主应用1就可以将宿主应用1和宿主应用2的信息存储于宿主应用1本地的数据库中。
在302中，宿主应用1启动后，从服务器端同步本终端设备中同一宿主联盟中各宿主应用存储小程序文件包的状况，并存储于宿主应用1本地的数据库中。
即宿主应用1在启动后，可以从服务器端获得本终端设备中宿主联盟的宿主应用都存储有哪些小程序文件包，例如包含包名、版本号等。
接续上例，假设宿主应用1从服务器端获得本终端设备中宿主应用1存储有小程序a和小程序b，宿主应用2存储有小程序b和小程序c，则将这些信息存储于宿主应用1本地的数据库中。
在303中，获取到宿主应用1中小程序c启动的事件后，判断宿主应用1的私有目录下是否存储有小程序c的文件包，如果是，执行304；否则执行305。
在304中，利用宿主应用1私有目录下存储的小程序c的文件包启动小程序c，结束本启动流程。
在305中，查询宿主应用1本地的数据库，确定同一宿主联盟的其他宿主应用是否存储有小程序c的文件包，如果是，执行306；否则，执行307。
在本步骤中，一方面确定同一宿主联盟的其他宿主应用是否存储有小程序c的文件包，另一方面确定存储的小程序c的文件包是否满足宿主应用1的版本要求，两方面均满足的情况下，执行306，否则执行307。通常宿主应用1如果需求的版本低于或等于其他宿主应用存储的小程序c的版本，则认为满足版本要求。
在306中，宿主应用1从其他宿主应用的私有目录下读取小程序c的文件包，并用以在宿主应用1中启动小程序c，结束本启动流程。
例如经查询若宿主应用2中已经存储有小程序c的文件包，则宿主应用1从宿主应用2的私有目录下读取小程序c的文件包来启动小程序c。
在307中，宿主应用1从对应的服务器端下载小程序c的文件包，存储于宿主应用1的私有目录下，并设置该私有目录的权限为宿主联盟的各宿主应用可读。
作为一种优选的实施方式，为了保证私有目录下内容的安全性，可以仅设置私有目录的权限为宿主联盟的各宿主应用可读不可写。
在308中，宿主应用1利用下载的文件包启动小程序c，并将存储小程序c的文件包的状况上报至服务器端。
在本实施例中，对于服务器端可以执行如图4中所示流程，包括：
在401中，接收对应宿主应用上报的该宿主应用存储小程序的文件包的状况。
宿主应用上报存储小程序的文件包的状况时，可以携带终端设备标识、宿主应用标识、小程序标识、小程序版本号等信息。服务器端接收这些信息后，在服务器端本地数据库进行对应维护。
例如，维护“终端设备标识-宿主应用标识-小程序标识-小程序版本号”这种关系项。
在402中，从其他宿主应用的服务器端同步其他宿主应用存储小程序的文件包的状况。
上述401和402并不一定按照上述顺序执行，步骤402中的同步可以是周 期性地，也可以是基于事件触发。
各宿主应用的服务器端可以针对宿主联盟互相开放用于进行同步的接口，服务器端能够将本地数据库中存储的各宿主应用存储小程序的文件包的状况同步给宿主联盟中的其他服务器端。
在403中，对同一终端设备中各宿主应用存储小程序的文件包的状况进行整合。
服务器端本地数据库存储的状况和从其他服务器端同步来的状况均是诸如“终端设备标识-宿主应用标识-小程序标识-小程序版本号”的形式，呢么可以将同一终端设备标识下的信息进行合并和去重处理，从而得到同一终端设备标识下各宿主应用存储小程序的文件包的状况。
在404中，向对应宿主应用同步该宿主应用所在终端设备中各宿主应用存储小程序的文件包的状况，以供对应宿主应用启动小程序使用。
可以在诸如图3中步骤302的状况下，获取宿主应用的终端设备标识，并向其下发该终端设备标识下各宿主应用存储小程序的文件包的状况。
实施例二、
图5为本发明实施例二提供的方法流程图，本实施例中对上述第二种实现方式进行描述。假设用户欲在宿主应用1中启动小程序c，如图5所示，由宿主应用1执行的方法可以包括以下过程：
在501中，获取宿主应用1中小程序c启动的事件。
在502中，判断宿主应用1的私有目录下是否存储有小程序c的文件包，如果是，执行503；否则执行504。
在503中，利用宿主应用1私有目录下存储的小程序c的文件包启动小程序c，结束本启动流程。
在504中，查询终端设备的共享数据库，确定同一宿主联盟的其他宿主应用是否存储有小程序c的文件包，如果是，执行505；否则，执行506。
在本发明实施例中，可以在终端设备中设置一共享数据库，该共享数据库对宿主联盟中所有宿主应用均开放读写权限。在共享数据库中维护有本终端设备中该宿主联盟下各宿主应用存储小程序的文件包的状况，例如包括包名和版本号。
在本步骤中，同样一方面确定同一宿主联盟的其他宿主应用是否存储有小程序c的文件包，另一方面确定存储的小程序c的文件包是否满足宿主应用1的版本要求，两方面均满足的情况下，执行505，否则执行506。通常宿主应用1如果需求的版本低于或等于其他宿主应用存储的小程序c的版本，则认为满足版本要求。
在505中，宿主应用1从其他宿主应用的私有目录下读取小程序c的文件包，并用以在宿主应用1中启动小程序c，结束本启动流程。
例如经查询若宿主应用2中已经存储有小程序c的文件包，则宿主应用1从宿主应用2的私有目录下读取小程序c的文件包来启动小程序c。
在506中，宿主应用1从对应的服务器端下载小程序c的文件包，存储于宿主应用1的私有目录下，并设置该私有目录的权限为宿主联盟的各宿主应用可读。
作为一种优选的实施方式，为了保证私有目录下内容的安全性，可以仅设置私有目录的权限为宿主联盟的各宿主应用可读不可写。
在507中，宿主应用1利用下载的文件包启动小程序c，并将存储小程序c的文件包的状况记录至共享数据库。
实施例三、
图6为本发明实施例三提供的方法流程图，本实施例中对上述第三种实现方式进行描述。假设用户欲在宿主应用1中启动小程序c，如图6所示，该方法可以包括以下过程：
在601中，宿主应用1获取小程序c启动的事件。
在602中，宿主应用1判断终端设备的共享存储空间是否存储有小程序c的文件包，如果是，执行603；否则执行604。
在本实施例中，在终端设备中设置共享存储空间，该共享存储空间对宿主联盟中各宿主应用开放读写权限。宿主联盟中的宿主应用均将下载的小程序的文件包存储于该共享存储空间以在宿主联盟范围内进行共享。
在本步骤中，同样一方面确定共享存储空间是否存储有小程序c的文件包，另一方面确定存储的小程序c的文件包是否满足宿主应用1的版本要求，两方面均满足的情况下，执行603，否则执行604。通常宿主应用1如果需求的版本 低于或等于已经存储的小程序c的版本，则认为满足版本要求。
在603中，宿主应用1从共享存储空间读取小程序c的文件包，启动小程序c，结束本启动流程。
在604中，宿主应用1从对应的服务器端下载小程序c的文件包，存储于终端设备的共享存储空间。
对于宿主应用1因版本需要下载小程序c的更高版本的文件包，则对于共享存储空间中已经存在的较低版本的文件包可以保留，也可以删除。
上述共享存储空间的形式本发明并不加以限制，例如可以采用SDCard，还可以采用其他形式的共享存储空间。
在605中，宿主应用1利用下载的文件包启动小程序c。
