具体实施方式
本申请以下实施例中所使用的术语只是为了描述特定实施例的目的，而并非旨在作为对本申请的限制。如在本申请的说明书和所附权利要求书中所使用的那样，单数表达形式“一个”、“一种”、“该”、“上述”、“该”和“这一”旨在也包括复数表达形式，除非其上下文中明确地有相反指示。还应当理解，本申请中使用的术语“和/或”是指并包含一个或多个所列出项目的任何或所有可能组合。
以下，术语“第一”、“第二”仅用于描述目的，而不能理解为暗示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征，在本申请实施例的描述中，除非另有说明，“多个”的含义是两个或两个以上。
本申请以下实施例中的术语“用户界面(user interface，UI)”，是应用程序或操作系统与用户之间进行交互和信息交换的介质接口，它实现信息的内部形式与用户可以接受形式之间的转换。用户界面是通过java、可扩展标记语言(extensible markup language，XML)等特定计算机语言编写的源代码，界面源代码在电子设备上经过解析，渲染，最终呈现为用户可以识别的内容。用户界面常用的表现形式是图形用户界面(graphic user interface，GUI)，是指采用图形方式显示的与计算机操作相关的用户界面。它可以是在电子设备的显示屏中显示的文本、图标、按钮、菜单、选项卡、文本框、对话框、状态栏、导航栏、Widget等可视的界面元素。
随着电子技术的发展，越来越多的消费者开始使用无线设备，例如蓝牙耳机、无线键鼠、手写笔如华为pencil以及其他设备等。
在有些场景中，本地用户想要将音乐或其他媒体文件分享给其他一个或多个对端用户时，本地电子设备将该媒体文件对应的链接分享给对端电子设备。一个示例性的内容如下图1所示。其中，本地电子设备为本地用户的电子设备，对端电子设备为对端用户的电子设备。其中，在具体的示例性说明中，本地电子设备可以为手机A、对端电子设备可以为手机B。其中，对端电子设备与本地电子设备互为对端。在本申请实施例中，在执行本申请实施例提供的通信方法前，连接从设备的电子设备也可以称为第二电子设备，第二电子设备的对端电子设备也可以称为第一电子设备。其中，从设备为上文中提到的蓝牙耳机、无线键鼠、手写笔等支持近场无线通信技术的电子设备。
图1为本申请实施例提供的本地电子设备上分享媒体文件的界面的一个示例性示意图。
其中，手机A为本地电子设备。图1中的界面1001为音乐应用程序界面的一个示例性的界面，在音乐应用程序的界面中存在控件1004。其中，控件1004为用于分享当前正在播放的媒体文件的控件。
响应于用户点击控件1004，手机A显示的界面变为图1中的界面1002。图1中的界面1002为选择分享用户的一个示例性的界面，该界面中存在与一个或多个用户对应的一个或多个控件。例如，如图1中的界面1002所示，该界面上存在控件1005以及控件1006。其中，控件1005对应于用户1；控件1006对应于用户2。
当本地用户点击本地电子设备上的控件1005，媒体文件对应的链接通过互联网被发送到用户1对应的 对端电子设备上；当本地用户点击本地电子设备上的控件1006，媒体文件的链接被发送到用户2对应的对端电子设备上。
图2为本申请实施例提供的对端电子设备上接收分享链接的界面的一个示例性示意图。
其中，对端电子设备上显示的界面如图2中的界面2001所示。
其中，手机B为本地电子设备。当本地电子设备将媒体文件对应的链接通过互联网传输到对端电子设备后，对端电子设备显示的界面上可以包括对应该链接的控件2003。
如图2中的界面2002所示，响应于对端用户点击对端电子设备上显示的控件2003，对端电子设备可以启动音乐应用程序，并开始播放该链接对应的媒体文件。
很显然的，如图1和图2所示的交互方法是一种分享音乐或其他媒体文件的方法。但是，很显然的，如图1和图2所示的方法需要本地电子设备或对端电子设备都安装有相同的应用程序，进一步的，当音乐或其他媒体文件为付费资源时，还需要本地用户和对端用户都是付费用户；再进一步的，本地用户和对端用户难以同步音乐或其他媒体文件的播放进度，或者由于网络的延迟，难以实时的同步音乐或其他媒体文件的播放进度。
很显然的，图1和图2所示的交互方法的操作十分繁琐，且要求对端电子设备满足一定的条件。
在另一些场景中，当本地用户与对端用户位置接近的时候，即在本地电子设备与对端电子设备的用户，用户可以通过操作指示本地电子设备连接对端用户的蓝牙耳机，进而实现音乐或其他媒体文件的分享，如图3所示。
图3为本申请提供的本地电子设备连接与对端电子设备连接的蓝牙耳机的一个示例性示意图。
在图3所示的内容中，手机A为本地电子设备，手机B为对端电子设备。
如图3所示，首先，手机B与耳机B连接；然后，对端用户通过操作指示手机B断开手机B和耳机B的连接；再然后，对端用户或本地用户通过操作将耳机B置于可连接状态，其中，可以通过长按耳机B上的功能按钮或者将耳机B放回充电盒中以使得耳机B进入可连接状态；最后，当蓝牙耳机进入可连接状态后，本地用户可以通过操作指示手机A与耳机B建立连接。
结合图3所示的内容，如图3所示的方法，需要本地用户或对端用户执行繁琐的操作，才能使得原先与对端电子设备连接的蓝牙耳机重新连接到本地电子设备；其次，如图3所示的方式，在蓝牙耳机进入可连接状态后还可能被除本地电子设备外的其他电子设备连接，安全性较差。
其中，处于可连接状态的电子设备可以被连接并且可以被配对。
在图3所示的内容中，耳机B从连接状态(connected)被手动置为广播状态(advertiser/advertising)，然后在建立连接后再进入连接状态(connected)。
结合上文叙述的内容，很容易可以看出，本地电子设备连接一个未和本地电子设备配对的并且和对端电子设备正在连接的蓝牙耳机或其他基于近场无线通信技术与对端电子设备连接的电子设备时，需要的用户执行的操作繁琐，且安全性较差。
基于此，本申请实施例提供了通信方法，可以使得本地电子设备可以以一种操作简便的、安全的方式与对端电子设备的从设备连接。
其中，对端电子设备的从设备为没有与本地电子设备配对过的电子设备；或者，对端电子设备的从设备为没有保存用于和本地电子设备配对的配对信息的电子设备。为了方便描述，后文中以从设备指代对端电子设备的从设备。在具体的示例性说明中，从设备可以为耳机B。
其中，从设备可以和对端电子设备连接；或者，从设备可以和对端电子设备曾经连接过，并且保存有用于和对端电子设备连接的相关信息。
其中，从设备可以基于任何近场无线通信技术与对端电子设备和/或本地电子设备连接，在此不做限定，例如，蓝牙、ZigBee、Wi-Fi、苹果无线直连连接(Apple Wirelsee Direct Link，AWDL)等。
其中，从设备可以为蓝牙耳机、无线键鼠、手写笔、游戏手柄、VR眼镜、钥匙(防盗门钥匙或汽车钥匙)、电视、电饭煲、智能家居设备等支持上文中至少一种近场无线通信技术的电子设备。
其中，从设备的设备类型不同，则本申请实施例提供的通信方法的应用场景也可以不同。下面示例性的介绍几种本申请实施例提供的通信方法的应用场景。

在图6A所示的内容中，手机A为本地电子设备，手机B为对端电子设备，从设备为与手机B连接的耳机B。
首先，手机B与耳机B保持连接；其次，手机A从手机B处获取用于连接和配对耳机B的信息；最后，手机A与耳机B连接后完成配对。
在图6A所示的内容中，耳机B从连接状态自动的变为可连接状态。
当耳机B为低功耗蓝牙(BLE)设备时，耳机B从连接状态变为广播状态，然后在建立连接后再进入连接状态。其中，广播状态也可以称为可连接状态。当耳机为经典蓝牙设备(BR/EDR)设备时，耳机B从连接状态变为寻呼扫描状态(page scan)，然后在建立连接后再进入连接状态。其中，寻呼扫描状态也可以成为可连接状态。
耳机B在广播状态时，会广播自己的信息进而使得本地电子设备可以发现并连接至耳机B。
如图6B所示，在耳机B和手机A连接一段时间后，耳机B与手机A断开连接，并且与手机B恢复连接。
其中，耳机B和手机A的连接时长可以与手机A上运行的业务有关，也可以是预设的固定值。例如，在上文中图4A和图4B所示的媒体文件分享场景中，耳机B和手机A的连接时长可以等于媒体文件的播放时长。

下面结合图7所示的内容，示例性的介绍本申请提供的通信方法。
图7为本申请实施例提供的通信方法的方法流程的一个示例性示意图。
如图7所示，本申请提供的通信方法，包括三个步骤，分别为步骤S701、步骤S702、步骤S703，下面分别介绍这三个步骤。
S701：本地电子设备与对端电子设备建立连接后，向对端电子设备发送第一请求。
其中，本地电子设备与对端电子设备建立连接的触发时机可以随场景的不同而不同，在此不做限定。
例如，在图4A和图4B所示的内容中，当用户在本地电子设备上点击控件4A04后，本地电子设备与对端电子设备建立连接。
又例如，在图5A和图5B所示的内容中，当用户在本地电子设备点击控件5A08后，本地电子设备开始接收广播，并在接收广播的过程中接收到对端电子设备发送的广播，发现对端电子设备。当本地电子设备发现对端电子设备后，本地电子设备的界面从界面5A04变为界面5B01后，当用户点击控件5B05后，本地电子设备与对端电子设备建立连接。
其中，第一请求可以是用于分享数据的请求；或者，第一请求可以是用于请求连接对端电子设备的从设备的请求。
可选地，在本申请一些实施例中，本地电子设备与对端电子设备也可以不建立连接，通过广播信道以广播的形式完成本申请实施例中部分或全部的数据交互。
可选地，在本申请一些实施例中，在本地电子设备与对端电子设备建立连接前，本地电子设备可以通过广播等其他多种方式，发现一个或多个对端电子设备。
可选地，在本申请一些实施例中，当用户在本地电子设备点击控件4A03后，本地电子设备开始发现一个或多个对端电子设备，在用户点击控件4B05后，本地电子设备与对端电子设备建立连接。
本地电子设备与对端电子设备可以建立多种连接，在此不做限定，例如，本地电子设备可以和对端电子设备之间的连接可以通过蓝牙、ZigBee、Wi-Fi、苹果无线直连连接(apple wireless direct link，AWDL)等多种协议或方式建立连接。
在本地电子设备与对端电子设备建立连接后，可以向对端电子设备发送第一请求。
可选地，在本申请一些实施例中，第一请求可以包括获取用于连接对端电子设备的从设备的信息，和/或，第一请求可以包括本地电子设备上运行的业务的信息。例如，在图4A和图4B所示的内容中，第一请求可以包括媒体文件分享业务。
可选的，在本申请一些实施例中，第一请求用于分享数据，如多媒体文件。例如，在图4A和图4B所示的内容中，第一请求可以用于分享音乐文件或音频流。
可选地，在本申请一些实施例中，第一请求可以包括从设备的设备类型，例如，设备类型可以是音频输出设备、蓝牙耳机、VR眼镜、遥控器等，在此不做限定。
可选地，在本申请一些实施例中，第一请求中可以携带时间信息，该时间信息可以表示本地电子设备需要使用从设备的时长。例如，在本地电子设备与从设备连接时长达到该时长后，从设备会与本地电子设备自动的断开，并且恢复从设备与对端电子设备的连接。
可选地，在本申请一些实施例中，在本地电子设备与对端电子设备建立连接的过程中，可以交换各自的公钥，用于在后续步骤中对需要数据交互的数据进行加密。
可选地，在本申请一些实施例中，本地电子设备可以通过对端电子设备获取对端电子设备的从设备的公钥，用于在后续步骤中对需要数据交互的数据进行加密。
可选地，在本申请一些实施例中，本地电子设备与对端电子设备可以在建立连接的过程中，本地电子设备和对端电子设备可以执行安全性验证，进而避免其他设备与本地电子设备或对端电子设备建立连接。可选地，在本申请一些实施例中，可以在建立连接后执行安全性验证，当安全性验证失败后则本地电子设备断开该连接。其中，安全性验证可以通过本地电子设备或对端电子设备的物理地址(Media Access Control Address，MAC)完成。
值得说明的是，当本地电子设备或对端电子设备通过经典蓝牙协议连接时，MAC为固定MAC；当本地电子设备与对端电子设备通过低功耗蓝牙连接时，MAC可以为固定MAC或随机MAC；类似的，后文中，本地电子设备与从设备的连接使用的MAC也可以根据协议的不同选择固定MAC或随机MAC。
值得说明的是，随着连接依赖具体的近场通信技术所遵循的协议的不同，本地电子设备和/或对端电子设备和/或从设备的标识也可以不同。
下面以图8、图9A和图9B所示的内容示例性的介绍在本地电子设备和对端电子设备之间通过蓝牙连接的情况下，本地电子设备与对端电子设备之间的连接过程，以及安全性验证的过程。
图8为本申请实施例提供的本地电子设备和对端电子设备建立连接的触发时机的一个示例性示意图。
S801：对端电子设备发送第一广播。
对端电子设备可以周期性的向周围的设备发送第一广播。
S802：本地电子设备基于第一广播确定第一距离小于等于距离阈值。
本地电子设备，在接收到第一广播后，基于第一广播的信号衰减确定对端电子设备与本地电子设备之间的距离为第一距离。本地电子设备判断第一距离和距离阈值的大小，若第一距离小于等于距离阈值，则执行步骤S803，与对端电子设备开始建立连接；若第一距离大于距离阈值，则本地电子设备不和对端电子设备建立连接。
可选地，在本申请一些实施例中，在上文中图5A所示的界面中，当用户在本地电子设备上点击界面5A03中的控件5A08后，本地电子设备开始接收或解析第一广播，并基于第一广播确定第一距离。
其中，基于第一广播确定第一距离的方法有许多种，在此不做限定。例如，可以通过接收信号强度指标(received signal strength indication，RSSI)确定。
可选地，在本申请一些实施例中，本地电子设备也可以主动发送第一广播，对端电子设备接收到该第一广播后向本地电子设备发送第一响应，本地电子设备基于第一响应确定第一电子设备和第二电子设备之间的距离。
可选地，在本申请一些实施例中，本地电子设备也可以主动发送第一广播，对端电子设备接收到该第一广播后向本地电子设备发送第一响应，其中，第一响应中包括有距离1，距离1为基于第一广播的RSSI确定的。本地电子设备基于距离1确定发送第一响应的电子设备是否为对端电子设备，即距离1小于等于距离阈值的情况下，该发送第一响应的电子设备为对端电子设备。
可选地，在本申请一些实施例中，本地电子设备也可以主动发送第一广播，对端电子设备接收到该第一广播后向本地电子设备发送第一响应，其中，第一响应中包括有距离1，距离1为基于第一广播的RSSI确定的。本地电子设备基于第一响应的RSSI确定距离2后，本地电子设备基于距离1的和距离2确定本地电子设备与发送第一响应的电子设备是否为对端电子设备，若距离1和距离2的平均值小于等于距离阈值的情况下，该发送第一响应的电子设备为对端电子设备。
S803：本地电子设备与对端电子设备建立连接。
结合图8所示的内容，可以理解的是，当本地电子设备和对端电子设备之间的距离小于距离阈值的情 况下，本地电子设备发现对端电子设备后，才会通过界面提醒用户是否建立与对端电子设备的连接。
图9A为本申请实施例提供本地电子设备与对端电子设备在建立连接过程中执行安全性验证的一个示例性示意图。
如图9A所示，本地电子设备与对端电子设备的建立连接过程包括如下步骤。
S9A01：发送广播。
本地电子设备在广播信道发送广播，以发现周边的可连接的电子设备。在图9A所示的内容中，对端电子设备和本地电子设备可以接收到该广播。
S9A02：发送公钥1的哈希值和MAC1的哈希值。
对端电子设备在接收到广播后，对端电子设备的响应包括向本地电子设备发送公钥1的哈希值和MAC1的哈希值。其中，对端电子设备的蓝牙MAC为MAC1。
可选的，在本申请一些实施例中，该MAC1为对端电子设备的公共地址(public address)。
对端电子设备和本地电子设备之间依然是通过广播信道进行的数据交互。
其中，公钥1和私钥1对应，私钥1为对端电子设备私有的；在执行步骤S9A05前，公钥1也是对端电子设备私有的。
可选地，在本申请一些实施例中，对端电子设备也可以发送公钥1和MAC运算结果的哈希值。
S9A03：存储公钥1的哈希值和MAC1的哈希值。
本地电子设备接收到公钥1和哈希值和MAC1的哈希值后，可以将公钥1和MAC1的哈希值保存在本地，在后续步骤中用于执行安全性验证。
可选地，在本申请一些实施例中，在对端电子设备也可以发送公钥1和MAC运算结果的哈希值的情况下，本地电子设备也可以验证该值。
S9A04：建立连接。
本地电子设备与对端电子设备建立连接。
值得说明的是，在本地电子设备与对端电子设备建立连接收，本地电子设备与对端电子设备数据交互是点对点的，即其他电子设备不能获取本地电子设备与对端电子设备数据交互的内容。
S9A05：发送公钥1和MAC1。
对端电子设备向本地电子设备发送公钥1和MAC1。
由于本地电子设备已经和对端电子设备建立连接，通过该连接发送的数据并不能被其他电子设备获取，所以其他电子设备并不能获取公钥1和MAC1。
S9A06：验证公钥1和MAC1。
本地电子设备通过公钥1的哈希值和MAC1的哈希值分别独立的验证公钥1和MAC1。
可选地，在本申请一些实施例中，在步骤S9A02中，对端电子设备可以发送公钥1的哈希值或MAC1的哈希值；在步骤S9A05中，对端电子设备可以发送公钥1或MAC1；在步骤S9A06中，本地电子设备可以验证公钥1或MAC1。
可以理解的是，本地电子设备通过验证公钥和/或MAC可以确定连接的对端电子设备即为用户选择的电子设备，而非其他电子设备；其中，用户选择电子设备的界面可以参考图4B中界面4B02中所示的内容，此处不再赘述。图9B为本申请实施例提供本地电子设备与其他电子设备在建立连接过程中执行安全性验证的一个示例性示意图。
如图9B所示，本地电子设备与对端电子设备的建立连接过程包括如下步骤。
S9B01：发送广播。
本地电子设备在广播信道发送广播，以发现周边的可连接的电子设备。在图9B所示的内容中，对端电子设备和本地电子设备可以接收到该广播。
S9B02：发送公钥1的哈希值和MAC1的哈希值。
具体的内容，参见上文中的步骤S9A02，此处不再赘述。
S9B03：转发接收到的广播。
由于其他电子设备也可以接收到本地电子设备的广播，其他电子设备可以转发本地电子设备的广播，并发送给对端电子设备。
可选地，在本申请一些实施例中，其他电子设备也可以在广播信道监听以直接获取对端电子设备向本地电子设备发送的公钥1的哈希值和MAC1的哈希值。
S9B04：发送公钥1的哈希值和MAC1的哈希值。
与步骤S9B02类似的，对端电子设备向发送广播的其他电子设备发送公钥1的哈希值和MAC1的哈希值。
S9B05：发送公钥1的哈希值和MAC1的哈希值。
其他电子设备在接收到公钥1的哈希值和MAC1的哈希值后，可以将该公钥1的哈希值和MAC1的哈希值发送到本地电子设备。
S9B06：存储公钥1的哈希值和MAC1的哈希值。
具体的内容，参见上文中的步骤S9A03，此处不再赘述。
S9B07：建立连接。
本地电子设备与其他电子设备建立连接。
S9B08：发送公钥2和MAC2。
在本地电子设备与其他电子设备建立连接后，其他电子设备向本地电子设备发送公钥2和MAC2。其中，由于对端电子设备没有以广播的形式发送过公钥1和MAC1，并且其他电子设备不能通过公钥1的哈希值恢复出公钥1以及不能通过MAC1的哈希值恢复出公钥1，所以其他电子设备并不能向本地电子设备发送公钥1和MAC1。
S9B09：确定公钥和MAC不匹配，断开连接。
本地电子设备在接收到其他电子设备发送的公钥2和MAC2后，执行安全性验证，判断公钥1的哈希值和公钥2是否匹配以及MAC1的哈希值与MAC2是否匹配。本地电子设备在确定公钥和MAC不匹配后，断开与其他电子设备的连接。
值得说明的是，在步骤S9B02和步骤S9B04中，对端电子设备可以发送公钥1的哈希值或MAC1的哈希值；在步骤S9B08中，其他电子设备可以发送公钥2或MAC2；在步骤S9B09中，本地电子设备确定公钥不匹配或MAC不匹配。
结合图8、图9A和图9B所示的内容，可以理解的是，本地电子设备和对端电子设备之间的连接可以是安全的。
进一步的，可选地，在本申请一些实施例中，本地电子设备与对端电子设备还可以交换会话密钥，其中，会话密钥可以由本地电子设备产生。示例性的，下面介绍交换会话密钥的方法。
图10为本申请实施例提供的本地电子设备与对端电子设备交换会话密钥的一个示例性的示意图。
如图10所示，本申请实施例提供的本地电子设备与对端电子设备交换会话密钥的方法包括三个步骤。
S1001：生成会话密钥。
在本地电子设备和对端电子设备建立连接后，本地电子设备可以生成会话密钥。其中会话密钥和会话公钥对应，会话公钥可以通过广播或其他方式发送到对端电子设备。
S1002：发送公钥1加密过的会话密钥。
本地电子设备向对端电子设备发送公钥1加密过得会话密钥。其中，公钥1的概念可以参考上文中的图8、图9A和图9B中的文字描述，此处不再赘述。其中，公钥1和私钥1对应，对端电子设备已知私钥1。
S1003：使用私钥1解密，获取会话密钥。
对端电子设备在接收公钥1加密过的会话密钥后，可以使用已知的私钥1解密该数据，进而获取到会话密钥。
其中，会话密钥用于在后续步骤加密本地电子设备与对端电子设备之间的数据交互。例如，对端电子设备发送从设备的公钥、从设备的MAC、从设备的序列号等信息时均可以使用会话密钥执行加密。
