技术领域

背景技术
在互联网时代，人们习惯将本地上编辑的文本上传到服务器上备份，以避免文本丢失。然而，当本地上的文本字节数太多的时候，当将文本上传到服务器的时候会花费更多的上传时间，但是网络可能会出现不稳定的情况，特别是对于移动终端利用移动网络上传文本的时候，这种网络不稳定的情况会更加严重，如果中间上传中断，还需要重新进行上传，这样会加重服务器的负担。
目前的一种解决办法是将本地文本截断为若干较小文件后分别上传，例如可以以5000字节分段，将本地文件截断为若干较小文件，但是中文字符占用2个字节，外文字符占用1个字节，如果简单以每5000字节分段，当中文字符占用第5000和第5001字节时，这种情况下截断会产生乱码，从而会使上传文本信息丢失。

此外，下面所描述的本申请不同实施方式中所涉及的技术特征只要彼此之间未构成冲突就可以相互结合。
本申请实施例提供了一种文本截断方法，如图1所示，该方法包括如下步骤：
S11.判断待截断文本占用的字节数是否大于预设截断字节数，当待截断文本占用的字节数小于或等于预设截断字节数时，则无需进行截断，截断结束；当待截断文本占用的字节数大于预设截断字节数时，则进入步骤S12。在这里，该文本包括中文字符和外文字符，其中中文字符占用2个字节，外文字符占用1个字节。
S12.将待截断文本转换为汉字编码字符集内的字节数组。在这里，汉字编码字符集内的字符例如可以是符合GB2312标准的中文或外文字符。
S13.在所转换的字节数组中截取预设截断字节数+1个字节。例如，预设截断字节数为5000，则截取5001个字节。
S14.将所截取的字节数组再转换回文本形式。
S15.将转换回的文本截取掉最后一个文字作为截断文本。
S16.将截断后剩余的文本作为新的待截断文本，并返回至步骤S11。
下面将详细说明本申请实施例的文本截断方法的原理。还是以预设截断字节数为5000为例，当从所转换的汉字编码字符集内的字节数组中截取5001个字节时，并将其再转换回文本形式后，最后一个文字存在如下三种情况：
1)最后一个文字是占用1个字节的外文字符，这时截取掉最后一个文 字后，所得到的截断文本占用5000个字节；
2)最后一个文字是本应与第5002个字节共同组成一个汉字的字符，这时截取掉最后一个文字后，所得到的截断文本占用5000个字节；
3)最后一个文字是占用2个字节的中文字符，这时截取掉最后一个文字后，所得到的截断文本占用4999个字节；
由此，可以保证截断不会产生乱码，且能保证截断文本等于或略小于预设截断字节数。
在步骤S16中，将剩余文本作为新的待截断文本，并返回至步骤S11，从而继续判断新的待截断文本占用的字节数是否大于预设截断字节数，当大于时继续按照步骤S12-S16进行截断，直至待截断文本占用的字节数小于或等于预设截断字节数。
通过上述方法步骤，可以快速、高效地将一个文本截断为若干占用字符数基本上等于预设截断字节数的小文本，且不会产生乱码。
本申请实施例还提供了一种文本上传方法，如图2所示，该方法包括如下步骤：
S21.获取待上传文本。在这里，该文本包括中文字符和英文字符，其中中文字符占用2个字节，英文字符占用1个字节。
S22.将待上传文本截断为若干截断文本。例如，可以采用上文中所述的文本截断方法，将待上传文本截断为若干小文本。在这里，预设截断字节数可以是用户终端出厂预设的，也可以由用户根据当前网络状况设定，例如，当网络状况较好时，可以将预设截断字节数设置得较大，当网络状况较差时，可以将预设截断字节数设置得较小。
S23.将截断后的若干截断文本分别上传至服务器。优选地，截断文本按序分别上传至服务器。
通过上述方法步骤，通过将待上传文本截断为若干小文本分别上传至服务器，避免了网络不稳定时上传大文本易中断的情形，减轻了服务器的负担。
为了进一步提升效率，上述步骤S22和S23可以同步执行，既完成一 个截断文本的截断后就开始上传该截断文本，而无需等待截断完成后再进行上传。
相应地，本申请实施例还提供了一种文本截断装置，如图3所示，该装置包括：
判断单元31，用于判断待截断文本占用的字节数是否大于预设截断字节数，当待截断文本占用的字节数小于或等于预设截断字节数时，则无需进行截断。在这里，该文本包括中文字符和外文字符，其中中文字符占用2个字节，外文字符占用1个字节。
第一转换单元32，用于当判断单元31判断待截断文本占用的字节数大于预设截断字节数时，将待截断文本转换为汉字编码字符集内的字节数组。在这里，汉字编码字符集内的字符例如可以是符合GB2312标准的中文或外文字符。
第一截取单元33，用于在所转换的字节数组中截取预设截断字节数+1个字节。例如，预设截断字节数为5000，则截取5001个字节。
第二转换单元34，用于将所截取的字节数组再转换回文本形式。
第二截取单元35，用于将转换回的文本截取掉最后一个文字作为截断文本。
通过上述各个单元，可以快速、高效地将一个文本截断为若干占用字符数基本上等于预设截断字节数的小文本，且不会产生乱码。
优选地，上述文本截断装置还可以包括：
保存单元36，用于将截断后剩余的文本作为新的待截断文本，并返回至判断单元31判断待截断文本占用的字节数是否大于预设截断字节数。
由此可以继续对待截断文本进行截断，直至待截断文本占用的字节数小于或等于预设截断字节数，从而可以快速、高效地将一个文本截断为若干占用字符数基本上等于预设截断字节数的小文本，且不会产生乱码。
本申请实施例还提供了一种文本上传装置，如图4所示，该装置包括：
获取单元41，用于获取待上传文本。在这里，该文本包括中文字符和英文字符，其中中文字符占用2个字节，英文字符占用1个字节。
文本截断单元42，用于将待上传文本截断为若干截断文本。例如，可以采用上文中所述的文本截断装置，将待上传文本截断为若干小文本。在这里，预设截断字节数可以是用户终端出厂预设的，也可以由用户根据当前网络状况设定，例如，当网络状况较好时，可以将预设截断字节数设置得较大，当网络状况较差时，可以将预设截断字节数设置得较小。
上传单元43，用于将截断后的若干截断文本分别上传至服务器。优选地，截断文本按序分别上传至服务器。
通过上述各个单元，通过将待上传文本截断为若干小文本分别上传至服务器，避免了网络不稳定时上传大文本易中断的情形，减轻了服务器的负担。
为了进一步提升效率，文本截断单元42将待上传文本截断为若干截断文本和上传单元43将截断后的若干截断文本分别上传至服务器同步执行，既完成一个截断文本的截断后就开始上传该截断文本，而无需等待截断完成后再进行上传。
