目标网络资源可以包括上述网络资源，丰富了待撤回网络资源的种类，从而提高了消息撤回的适用性。
上述所有可选技术方案，可以采用任意结合形成本发明的可选实施例，在此不再一一赘述。
图2是根据另一示例性实施例示出的一种消息撤回方法的流程图，本实施例以该消息撤回方法由终端执行来举例说明。该消息撤回方法可以包括如下几个步骤：
在步骤201中，接收消息，该消息携带目标网络资源。
本发明实施例提供的方法，终端在执行删除目标网络资源操作之前，为了能够根据消 息撤回指令，确定目标网络资源，终端在接收目标消息并下载其携带的目标网络资源之后，需要建立该目标消息的消息标识与目标网络资源在本地的存储路径之间的映射关系，以便终端在接收到该目标消息的撤回指令时，根据撤回指令携带的消息标识和该映射关系，确定目标网络资源。
终端所接收到的消息可以是由其它任一终端发送，消息中携带有网络资源。该消息可以只包括网络资源，例如，该消息为其他用户在即时通讯对话时发送的一条图片消息，当然，该消息也可以包括网络资源和其它内容，例如，该消息可以包括了一张图片和一段文字信息。
其中，上述目标网络资源可以是图片、视频、音频、动画或文档等。当然，目标网络资源也可以是指上述任一种形式资源的压缩文件，例如，目标网络资源为包括压缩文件M，该压缩文件M由文档m1和文档m2压缩而成。
在步骤202中，根据用户的下载操作，下载目标消息携带的目标网络资源。
终端接收到其它任一终端发送的目标消息，用户可以对该目标消息中携带的目标网络资源进行下载，当终端检测到用户对目标网络资源的下载操作时，可以将该目标网络资源下载至用户指定的存储位置中，相应地，终端可以得到目标网络资源的存储路径，例如，终端将文档resourceA下载至E:\document存储位置中，则终端可以得到该文档resourceA的存储路径为E:\document\resourceA.doc。当然，终端也可以将该目标网络资源下载至系统默认的存储位置中，例如，系统默认的存储位置为C:\，则终端将文档resourceA下载至C:\存储位置中，此时，得到文档resourceA的存储路径为C:\resourceA.doc。
例如，若终端接收到某一目标消息，该目标消息中携带的目标网络资源为文档resourceA，用户指定的存储位置为E:\document，则当终端检测到用户对该文档resourceA的下载操作时，将该文档resourceA下载至E:\document存储位置中，并得到该文档resourceA的存储路径为E:\document\resourceA.doc。
在一种可能的实现方式中，若在目标网络资源的下载过程中，接收到消息撤回指令，则中断下载过程，在本实施例中，将不再执行后续步骤。在这种情况下，终端可以禁止用户对该目标消息执行任何操作，也即在当前显示的交互界面中，终端不允许用户执行任何操作，直到该目标消息被撤回，不允许执行的操作可以包括但不限于转发、收藏或复制等操作。
在步骤203中，建立目标网络资源的存储路径与目标消息的消息标识之间的映射关系。
其中，目标消息的消息标识用于唯一标识该目标消息，以使得终端可以根据消息标识，可以唯一确定该目标消息。
终端可以维护一个数据库，该数据库用于以消息标识为索引，对目标网络资源的存储 路径与目标消息的消息标识之间的映射关系进行存储。基于上述映射关系，终端根据目标消息的消息标识，可以唯一确定目标网络资源的存储路径。
以上述例子为例，若携带文档resourceA的目标消息的消息标识为message ID A，则下载文档resourceA后，终端建立存储路径E:\document\resourceA.doc与该目标消息的消息标识message ID A之间的映射关系，并存储于数据库中。
在一种可能的实现方式中，用户还可能对已下载的目标网络资源进行复制粘贴，这种情况下，复制粘贴后的目标网络资源对应着新的存储路径，为了保证对目标网络资源删除的完整性，还需要删除复制粘贴后的目标网络资源。为此，当检测到对目标网络资源的任意复制粘贴操作时，将任意复制粘贴操作所对应的目标存储路径和目标网络资源的存储路径均作为目标消息的消息标识对应的存储路径，即，终端不仅建立目标网络资源的存储路径与目标消息的消息标识之间的映射关系，且，还需要建立任意复制粘贴操作所对应的目标存储路径与目标消息的消息标识之间的映射关系。
上述当检测到目标网络资源的任意复制粘贴操作时，将任意复制粘贴操作所对应的目标存储路径也作为目标消息的消息标识对应的存储路径，保证了消息撤回的完整性。
例如，若文档resourceA的存储位置为E:\document，则文档resourceA的存储路径为E:\document\resourceA.doc，且，用户将文档resourceA进行了复制粘贴，并将复制粘贴后的文档resourceA保存至D:\document存储位置中，则复制粘贴后的文档resourceA的存储路径为D:\document\resourceA.doc，终端将E:\document\resourceA.doc和D:\document\resourceA.doc作为消息标识message ID A对应的存储路径，即，终端分别建立存储路径F:\document\resourceA.doc、E:\document\resourceA.doc与消息标识message ID A之间的映射关系。
在步骤204中，当检测到目标网络资源的存储路径发生变化时，在已下载网络资源的存储路径与消息标识之间的映射关系中，更新目标网络资源的存储路径。
在实际应用过程中，用户可以对目标网络资源的存储位置进行更改，相应地，目标网络资源的存储路径就会发生变化。对目标网络资源的存储位置的更改操作可以包括：对目标网络资源的存储位置中的最后一个文件夹名称进行重命名更改，例如，将文档resourceA的存储位置E:\document中的document文件夹重命名为folder，则更改后的文档resourceA的存储位置为E:\folder，相应地，文档resourceA的存储路径由E:\document\resourceA.doc变化为E:\folder\resourceA.doc；或者，对目标网络资源的存储位置的更改操作也可以是指，将目标网络资源搬移至根目录不同的其它存储位置中，例如，将存储在E:\document存储位置中的文档resourceA，搬移至F:\document存储位置中，相应地，文档resourceA的存储路径由E:\document\resourceA.doc变化为 F:\document\resourceA.doc。
当终端检测到目标网络资源的存储路径发生变化时，获取变化后的存储路径，并在数据库中存储的已下载网络资源的存储路径与消息标识之间的映射关系中，将原存储路径更新为变化后的存储路径。
如此，即便目标网络资源在本地的存储路径发生变化，终端也可以通过获取变化后的存储路径，更新上述映射关系中目标网络资源的存储路径，并根据更新后的映射关系，确定目标网络资源的存储路径，如此，提高了删除目标网络资源的可靠性。
例如，文档resourceA的原存储位置为E:\document，现用户将该文档resourceA移至F:\document存储位置中，此时文档resourceA的存储路径由原E:\document\resourceA.doc变化为F:\document\resourceA.doc。终端检测到该变化时，在数据库存储的E:\document\resourceA.doc与消息标识message ID A之间的映射关系中，将E:\document\resourceA.doc更新为F:\document\resourceA.doc，即，终端重新建立了消息标识message ID A与F:\document\resourceA.doc之间的映射关系。
在步骤205中，接收消息撤回指令，消息撤回指令至少携带待撤回的目标消息的消息标识。
其中，消息撤回指令由消息服务器在接收到消息发送方对目标消息的撤回请求时触发。当消息发送者想要将发送出去的消息撤回时，可以通过客户端提供的消息撤回按键，向服务器提交目标消息撤回请求，该目标消息撤回请求可以携带该目标消息的消息标识，服务器接收目标消息撤回请求，向目标消息接收终端发送消息撤回指令，该消息撤回指令携带目标消息的消息标识，以使得目标消息接收终端对目标消息以及属于该目标消息的网络资源进行删除。
当终端接收到服务器推送的目标消息撤回指令时，获取该目标消息撤回指令携带的消息标识。
在步骤206中，根据已下载网络资源的存储路径与消息标识之间的映射关系，确定目标网络资源的存储路径，目标网络资源为从目标消息中下载的网络资源。
终端根据撤回消息指令中携带的消息标识，以及数据库中存储的已下载网络资源的存储路径与消息标识之间的映射关系，可以从数据库中确定目标网络资源的存储路径，从而找到目标网络资源。
例如，撤回消息指令中携带的消息标识为message ID A，终端根据该消息标识message ID A，基于已下载网络资源的存储路径与消息标识message ID A之间的映射关系，从数据库中确定与消息标识message ID A具有映射关系的存储路径E:\document\resourceA.doc，并从该存储路径E:\document\resourceA.doc中，可以找到目标网络资源resourceA。
在步骤207中，删除目标消息。
终端根据消息撤回指令中的携带的消息标识，删除该目标消息。如上述例子，终端根据消息撤回指令携带的消息标识message ID A，确定该目标消息，并将其从终端中删除。接收消息后，可以将消息存储于一个指定文件夹中，终端从该指定文件夹中删除待撤回的目标消息。
在步骤208中，从目标网络资源的存储路径中，删除目标网络资源。
根据上述步骤206由消息标识确定了目标网络资源的存储路径，终端从该存储路径中，删除目标网络资源。如上述例子，终端根据消息标识message ID A，确定文档resourceA的存储路径为E:\document\resourceA.doc，并从该存储路径中，删除文档resourceA。
在一种可能的实现方式中，当删除目标网络资源后，终端还可以显示删除提示信息，其中，删除提示信息用于提示已经从本地删除目标网络资源和目标消息。上述在终端将目标网络资源和目标消息删除时，通过显示的方式提示用户，避免自动删除给用户造成的困扰，提高了用户体验。
本发明实施例提供的方法，通过接收消息撤回指令，根据其携带的消息标识、以及已下载目标网络资源的存储路径与目标消息的消息标识之间的映射关系，确定待删除网络资源的存储路径，并从中删除该目标网络资源和待撤回的目标消息。如此，即使用户将目标网络资源下载至本地，终端也可以将其自动删除，避免了网络资源泄露的问题，保证了消息撤回的完整性。
