Description

表情字符串的处理方法及装置 技术领域
本发明涉及计算机技术领域，尤其涉及一种表情字符串的处理方法及装置。
背景技术
Emoji词义来自日语えもじ，在日语中的含义是字符，是日本在无线通信中所使用的视觉情感符号，在苹果公司发布的IOS 5输入法引入了Emoji之后，这种表情符号逐渐流行起来。目前，图片表情几乎在所有的移动聊天软件得到了广泛地应用，比如微信、易信、QQ都支持表情的发送。图片表情本质上是一个符合特定格式的字符串，大多的实现方案都是将图片表情和其所对应的字符串建立一层对应关系，比如"[:smile]"对应着“微笑”表情，"[:cry]"对应着“哭泣”表情。
操作系统自带的TextView控件具有强大的图文混排处理能力，它主要通过图文混排函数SpannableString方便地实现文本到图片表情的转换，可以将制定范围内的文字替换为Emoji表情，但是虽然指定范围内显示的是表情，实际上TextView控件内部保存的仍旧是原始的字符串，即图片表情与字符串被视为两个单独的个体存在，导致某些应用(例如输入法)进行图片表情处理时，需要对该图片表情执行多次才能完成操作。例如，图1示出了现有技术中客户端输入图片表情的一个示例图，图1中排在第2位的图片表情需要删除，图2示出了现有技术中客户端进行图片表情删除后出现表情编码的一个示例图，由图2可以看出，删除图片表情之后，后台的原始字符串“/::”仍然存在，并显示在客户端的界面中，若需要将“/::”删除，则需要二次进行删除操作。
由此可以看出，现有技术中，图片表情处理操作可能需要多次操作才能够完成，操作次数的增多会浪费相应的资源，同时也增加了操作难度。

具体实施方式
下面结合附图和具体的实施方式对本发明作进一步的描述。
为解决上述技术问题，本发明实施例提供了一种表情字符串的处理方法。图3示出了根据本发明一个实施例的表情字符串的处理方法的处理流程图。参见图3，该方法至少包括以下步骤S302至步骤S304。
首先，执行步骤S302，对于具备图片表情与表情字符串的第一映射关系的图片表情，在第一映射关系的基础上，增加表情字符串与单一码(unicode)的第二映射关系。
需要说明地是，在本发明实施例中，图片表情与表情字符串的第一映射关系是表情库中的现有映射关系，正在因为第一映射关系的识别性有一定的漏洞，导致图片表情和表情字符串可能会被视为两个单独的个体存在，进而需要执行多次才能够完成图片表情的处理。为解决这一技术问题，本发明实施例对第一映射关系进行改进，在第一映射关系的基础上，增加了第二映射关系，即表情字符串与单一码之间的映射关系。
具体地，在一个实施例中，设置一个Emoji表情库，该表情库包含常用图片表情，同时该Emoji表情库中存储有图片表情和其对应字符串的第一映射关系，此外，该Emoji类所有图片表情可以保存在类目录(例如：assets目录)中。
根据步骤S302提及的增加表情字符串与unicode的第二映射关系对本实施例的Emoji表情库中的表情字符串进行处理，为其设置对应的unicode。需要注意地是，unicode是一种在计算机上使用的国际标准编码，能够用统一并且唯一的二进制编码表示世界上所有的书写语言中可能用于电脑通讯的字元、象形文字和其他符号。正是因为unicode具备唯一性，使得图片表情、表情字符串与unicode三者间建立的映射关系也具有唯一性，这样每个图片表情都可以用一个唯一的字符表示。执行程序时，因后台默认unicode的唯一性和三者建立的映射关系的唯一性，通过具备唯一性的映射关系中的任意一个元素可以查找到其他两个元素，从而使得图片表情的操作也具备唯一性，对任意一个元素进行操作时，均能够根据图片表情、表情字符串与unicode三者间建立的具备唯一性的映射关系，将涉及到的其他两个元素进行处理，能够保证一次完成图片表情处理，从而避免了一个表情处理需要多次操作所导致的时间缓慢、资源浪费、用户感受体验较差等问题。进一步，为保证整个Emoji表情库的所有表情都不会出现多次处理才能够完成一个处理需求的情况，优选地，可以将整个Emoji表情库的全部图片表情均增设第二映射关系，使表情库中的每个图片表情均可以映射到唯一的unicode，对表情库中的任一图片表情进行处理时，因unicode 的唯一性及三者建立的映射关系的唯一性，各图片表情的操作处理均能一次完成。
其中，本发明实施例将增设的单一码设置于客户端的空白区域，使其充分利用客户端的空白区域，并使得增设的单一码清楚简洁，其增设的映射关系也容易获取，避免与其他已有代码混淆在同一区域，导致代码叠加所造成的混乱，也降低了获取难度。
实际应用中，增加的表情字符串与unicode间的第二映射关系可以通过轻量级的数据交换格式(例如：json)保存在类目录(例如：assets目录)中，可以定义为如下格式的映射表：
{"unicode":"0xF001","imgCode":"[:smile]"}
{"unicode":"0xF002","imgCode":"[:cry]"}
......
当图片表情处理程序运行时将上述映射表加载至内存，供客户端查找、提取、处理等等。
步骤S302增设了第二映射关系之后，本发明实施例执行步骤S304，结合第一映射关系和第二映射关系，以在图片表情和单一码间建立对应映射关系。
具体地，图4示出了根据本发明一个实施例的图片表情、表情字符串及unicode的映射关系示意图。参见图4，第一映射关系和第二映射关系通过表情字符串实现两者的结合，使得图片表情与unicode建立对应的映射关系。以微笑表情为例，结合微笑图片表情与微笑表情字符串"[:smile]"的第一映射关系及"[:smile]"与单一码"0xF001"第二映射关系，在微笑图片表情与单一码"0xF001"建立对应的映射关系。
综上可知，本发明实施例提供了一种表情字符串的处理方法及装置，由于图片表情与表情字符串的第一映射关系在用于识别图片表情时存在一定的漏洞，导致图片表情与表情字符串可能会被视为两个单独的个体存在，此时，若需要对表情进行处理，可能需要得执行多次才能完成处理，为解决这一技术问题，本发明增加了表情字符串与unicode的第二映射关系，unicode是一种在计算机上使用的国际标准编码，能够用统一并且唯一的二进制编码表示世界上所有的书写语言中可能用于电脑通讯的字元、象形文字和其他符号，即，unicode具备唯一性。正是因为unicode具备唯一性，使得图片表情、表情字符串与unicode三者间建立的映射关系也具有唯一性，此时若对图片表情进行处理，通过具备唯一性的映射关系中的任意一个元素可以查找到其他两个元素，从而使得图片表情的操作也具备唯一性，对任意一个元素进行操作时，均能够根据图片表情、表情字符串与unicode三者间建立的具备唯一性的映射关系，将涉及到的其他两个元素进行处理，因此能够保证一次完成图片表情 处理，从而避免了一个表情处理需要多次操作所导致的时间缓慢、资源浪费、用户感受体验较差等问题。
在图片表情与单一码之间建立起对应的映射关系(即步骤S304)之后，若接收到某个图片表情的处理消息，则可以根据增设的unicode对图片表情进行处理。具体地，图5示出了根据本发明一个实施例的图片表情的处理方式的处理流程图。参见图5，该方法至少包括步骤S502至步骤S504。
步骤S502、接收到某个图片表情的处理消息时，利用该图片表情和单一码间建立的对应映射关系，查找到与该图片表情对应的单一码；
步骤S504、对查找到的单一码执行步骤S502的处理消息中携带的处理操作。
在本发明实施例中，如前文所述，因单一码具备唯一性，使得三者间的映射关系也具备唯一性，使得对图片表情的操作也具备唯一性，单一码执行完成处理操作后，使得操作界面上的图片表情在后台程序中有一个唯一的字符表示，再对该图片表情进行处理时，后台对单一码对应的图片表情及表情字符串均进行处理，从而避免了因一个表情处理需多次操作所导致的时间缓慢、资源浪费、用户感受体验较差等问题。
本发明实施例中，上述步骤的实施主体可能是即时通信客户端，例如QQ、易信、微信、短信、彩信等能够使用文字、图片等文本格式进行沟通的客户端。
进一步，在本发明的一个优选实施例中，步骤S502所提及的查找到与图片表情对应的单一码具体可以包括如下步骤：
步骤1、根据图片表情与表情字符串的第一映射关系，查找到该图片表情对应的表情字符串；
步骤2、根据表情字符串与unicode的第二映射关系，根据步骤1中查找到的表情字符串，进一步查找到与该表情字符串对应的单一码。
具体地，以微笑表情为例，输入微笑图片表情时，程序运行时通过建立的第一映射关系，查找到微笑图片表情对应的表情字符串"[:smile]"，通过增加建立的第二映射关系，查找到该表情字符串对应的单一码"0xF001"。
在本发明的一个优选实施例中，步骤S504所提及对查找到的单一码执行处理消息中携带的处理操作，可以包括如下步骤：
步骤1、调用与处理消息对应的处理函数；
步骤2、利用处理函数设置单一码与图片表情位图间的转换关系；
步骤3、利用处理函数对单一码执行上述处理消息中携带的处理操作，并利用单一码与图片表情位图间的转换关系将处理操作映射到图片表情位图。
本发明实施例中步骤2提及的利用处理函数设置单一码与图片表情位图间的转换关系，其中，图片表情位图是由Emoji表情库中所有图片表情解析而成，即首先需要将图片表情转化为Windows标准格式图形文件，进而对Windows标准格式图形文件进行解析，形成位图文件(bitmap)，bitmap是使用像素阵列来表示图片表情，将图片表情定义为由点(例如像素)组成，每个点可以由多种色彩表示，包括2、4、8、16、24和32位色彩。将每个图片表情解析成对应的位图文件bitmap后，将对应的bitmap与其对应的文件名配对，并用列表(List)对配对结果进行保存，List中各项可以定义为如下格式，
public class Emoji{
/**表情名称*/
public String name；
/**对应图片*/
public Bitmap bitmap；
}，
以微笑表情为例，
public class Emoji{
/**Smile*/
public String name；
/**Smile Image*/
public Bitmap bitmap；
}。
数据库中的各图片表情被解析成对应的bitmap并进行保存，相应地，当进行图片表情处理时，可以调用相应的bitmap并显示在客户端界面。
具体地，以微笑表情输入为例，查找微笑图片表情对应的单一码后"0xF001"，由于输入部分包括图片，程序运行时Textview控件中需要新建一个图文混排函数SpannableString，然后调用setSpan函数设置单一码"0xF001"与微笑图片表情对应的位图文件的转换关系，即将查找到的单一码"0xF001"转换为位图文件，最后将得到的SpannableString插入到编辑文本当前光标位置完成微笑图片表情的输入。
对于常用的即时通信类客户端，信息传输是双方的，任意一个信息(常见的是文本信息)由本地客户端生成，上传至服务器后，由服务器对该信息进行处理，进而将处理后的信息转发至对方客户端。由此可见，信息生成之后，服务器端与对方客户端均需要能够识别出相应信息。而本发明实施例中，对图片表情增设了第二映 射关系，如果直接将包含增设了第二映射关系的图片表情发送出去，则服务器、对方客户端均可能对此无法识别。
因此，以文本内容为例，为了保障服务器能够识别文本内容，并能够将文本内容完整地转发至对方客户端，需要对文本内容进行处理。图6示出了根据本发明一个实施例的包括至少一个图片表情的文本输入结束后，将该文本上传至服务器的处理流程图。参见图6，该文本上传的流程至少包括步骤S602至步骤S608。
步骤S602、获取文本的文本内容；
步骤S604、解析出其中的单一码，利用表情库中存储的单一码与表情字符串的逆向映射关系查找到对应的表情字符串；
步骤S606、使用查找出的对应的表情字符串替换单一码在上述文本中的位置；
步骤S608、将替换结束得到的文本上传至服务器。
本发明实施例中步骤S604利用表情字符串与unicode的逆向映射关系，查找到unicode对应的表情字符串，图7示出了根据本发明一个实施例的图片表情、表情字符串及unicode的结合逆向映射关系示意图。在实际应用中，图片表情、表情字符串及unicode的映射关系均是可逆的，例如某些智能机内核能够识别的是表情字符串，在实际处理中就可以使用表情字符串与图片表情的逆向映射关系查找到图片表情，进而显示图片表情。同理，也可能存在某些终端，其后台仅能够识别unicode，进而可以根据unicode与图片表情间的间接逆向映射关系查找到对应的图片表情，并显示在终端界面。
具体地，以包括微笑表情的文本内容为例，客户端将该文本内容上传至服务器时需要对其进行如下处理，首先获取编辑文本(EditText)中的文本内容，解析出文本内容中的单一码"0xF001"，通过单一码"0xF001"与对应的表情字符串的逆向映射关系找到微笑表情字符串"[:smile]"，并将微笑表情字符串"[:smile]"替换掉单一码"0xF001"，最后将替换后的文本上传至服务器。
图6所示的文本内容处理流程中，对使用了第二映射关系的文本内容进行处理，根据单一码与表情字符串的逆向映射规则查找对应的表情字符串，进而使用查找到的表情字符串替换单一码在文本中的位置，该修改使得文本信息恢复到未使用第二映射关系之前，可视为原始文本信息。随后，将恢复得到的原始文本信息上传至服务器，由服务器进行传输。图6所示的恢复操作的目的是能够有效地防止服务器端不识别增设的unicode，避免服务器在识别文本内容时出现文本内容乱码等问题，或者在传输文本至其他客户端时发生传送错误、丢包等问题。另一方面，图6所示的恢复操作在客户端侧执行，并不需要服务器参与，服务器不需要为增设的表情字符 串与单一码的映射关系增加新的数据解析方式，无须作任何改动，因此，本发明实施例能够在不改变服务器等增加硬件成本的情况下，完成图片表情处理操作，节省了大量资源。综上，上述文本内容处理操作更加有利于服务器响应服务请求，保障服务的质量。
另外，本发明提出的图片表情与表情字符串的第一次映射关系和表情字符串与unicode的第二次映射关系对服务器来说是透明的，服务器不需要做额外的兼容处理。
下面，以客户端将“今天老师给小明发了一朵小红花(此处为“小红花”图片表情)”的文本内容发送至对方客户端作为本发明一个具体实施例，进一步说明本发明的表情字符串的处理方法的流程及按照本发明生成的图片表情进行处理操作时的有益效果。
需要输入的文本内容既包括“今天老师给小明发了一朵小红花”的文字内容，又包括“小红花”的图片内容。客户端编辑文本输入完“今天老师给小明发了一朵小红花”的文字部分后，需要输入小红花图片表情，此时，后台程序根据图片表情与表情字符串的第一映射关系，查找到小红花图片表情对应的表情字符串"[:red flower]"，再根据增设的表情字符串与unicode的第二映射关系，查找到"[:red flower]"对应的单一码"0xF003"。之后单一码"0xF003"执行处理操作，首先编辑文本Textview控件中新建一个图文混排函数SpannableString，然后调用setSpan函数将单一码"0xF003"转换为小红花图片表情的位图文件，得到的SpannableString插入到编辑文本当前光标位置完成小红花图片表情的输入。客户端完成“今天老师给小明发了一朵小红花(此处为“小红花”图片表情)”的文本内容输入后，需要将该段文本内容上传至服务器，并由服务器转发至对方客户端。由于该文本内容中小红花图片表情是由增设的单一码"0xF003"执行处理操作完成输入的，为了保障服务器能够识别小红花图片表情，需要对其进行如下处理，获取“今天老师给小明发了一朵小红花(此处为“小红花”图片表情)”的文本内容，解析出该文本内容中小红花图片表情的单一码"0xF003"，并根据单一码与表情字符串的逆向映射关系，查找到单一码"0xF003"对应的表情字符串"[:red flower]"，并在后台将"[:red flower]"替换掉单一码"0xF003"，即文本信息恢复到未使用第二映射关系之前，将恢复得到的文本信息上传至服务器，由服务器传送至对方客户端。
需要说明地是，文本内容中的“小红花”图片表情是由增设的单一码"0xF003"执行操作完成输入的，由于单一码"0xF003"具有唯一性，使得小红花图片表情、"[:red flower]"与单一码"0xF003"三者建立的映射关系也具有唯一性，若需要对“今天老师给小明发了一朵小红花(此处为“小红花”图片表情)”中的“小红花”图片表情进行删除 或者复制等处理操作时，后台执行程序时，因默认"0xF003"的唯一性及三者建立的关系的唯一性，使对小红花图片表情的操作也具备唯一性，将涉及到的小红花图片表情、"[:red flower]"与单一码"0xF003"三个元素均进行处理，因此能够一次完成处理操作。
基于同一发明构思，本发明实施例还提供了一种表情字符串的处理装置。图8示出了根据本发明一个实施例的表情字符串的处理装置的结构示意图。参见图8，该装置至少包括：
增加模块810，适于对于具备图片表情与表情字符串的第一映射关系的图片表情，在第一映射关系的基础上，增加表情字符串与单一码unicode的第二映射关系；
建立模块820，与增加模块810耦合，适于结合第一映射关系和第二映射关系，以在图片表情和单一码间建立对应映射关系。
在表情字符串处理装置中增加了表情字符串与unicode的第二映射关系后，本发明实施例可以进一步根据增设的映射关系对图片表情进行处理，图9示出了根据本发明一个实施例的表情字符串的处理装置的另一种结构示意图，该装置至少还包括：
查找模块830，与建立模块820耦合，适于接收到某个图片表情的处理消息时，利用图片表情和单一码间建立的对应映射关系，查找到与该图片表情对应的单一码；
处理模块840，与查找模块830耦合，适于对查找到的单一码执行处理消息中携带的处理操作。
在一个优选的实施例中，查找模块830还适于：
根据第一映射关系，查找到该图片表情对应的表情字符串；
进而，根据第二映射关系，查找到与该表情字符串对应的单一码。
在一个优选的实施例中，查找模块830还适于：
调用与处理消息对应的处理函数；
利用处理函数设置单一码与图片表情位图间的转换关系；
利用处理函数对单一码执行处理消息中携带的处理操作，并利用单一码与图片表情位图间的转换关系将处理操作映射到图片表情位图。
在一个优选的实施例中，参见图10，表情字符串的处理装置还可以包括：
上传模块850，与处理模块840耦合，适于在包括至少一个图片表情的文本输入结束后，按如下步骤将该文本上传至服务器：
获取上述文本的文本内容；
解析出其中的单一码，利用表情库中存储的单一码与表情字符串的逆向映射关 系查找到对应的表情字符串；
使用查找出的对应的表情字符串替换单一码在所述文本中的位置；
将替换结束得到的文本上传至服务器。
本发明实施例提供的任意一个优选实施例或其组合，可应用于多客户端间的消息传送过程，图11示出了根据本发明一个优选实施例的多客户端间消息传输的系统示意图。参见图11，该系统包括服务器1110，以及分别通过服务器1110进行消息传输的多客户端1120。图11的客户端的个数仅仅为示意值，在实际应用中可能成千上百甚至更多，本发明对此不做任何限定。
综上，采用本发明实施例提供的表情字符串的处理方法及装置可以达到如下有益效果：
本发明实施例提供了一种表情字符串的处理方法及装置，由于图片表情与表情字符串的第一映射关系在用于识别图片表情时存在一定的漏洞，导致图片表情与表情字符串可能会被视为两个单独的个体存在，此时，若需要对表情进行处理，可能需要得执行多次才能完成处理，为解决这一技术问题，本发明增加了表情字符串与unicode的第二映射关系，unicode是一种在计算机上使用的国际标准编码，能够用统一并且唯一的二进制编码表示世界上所有的书写语言中可能用于电脑通讯的字元、象形文字和其他符号，即，unicode具备唯一性。正是因为unicode具备唯一性，使得图片表情、表情字符串与unicode三者间建立的映射关系也具有唯一性，此时若对图片表情进行处理，通过具备唯一性的映射关系中的任意一个元素可以查找到其他两个元素，从而使得图片表情的操作也具备唯一性，对任意一个元素进行操作时，均能够根据图片表情、表情字符串与unicode三者间建立的具备唯一性的映射关系，将涉及到的其他两个元素进行处理，因此能够保证一次完成图片表情处理，从而避免了一个表情处理需要多次操作所导致的时间缓慢、资源浪费、用户感受体验较差等问题。
