目錄一、最近使用secure_filename發(fā)現(xiàn)的問(wèn)題二、后面找到了原因三、解決方案四、效果展示

前言：最近使用到了secure_filename，然后悲劇的發(fā)現(xiàn)中文居然不展示出來(lái)，于是我慢慢的debug，終于找到問(wèn)題了。

一、最近使用secure_filename發(fā)現(xiàn)的問(wèn)題

文件名是中文版的，悲劇的是中文以及其他特殊字符會(huì)被省略。

二、后面找到了原因

原來(lái)secure_filename()函數(shù)只返回ASCII字符，非ASCII字符會(huì)被過(guò)濾掉。

三、解決方案

找到secure_filename(filename)函數(shù)，修改它的源代碼。

secure_filename(filename)函數(shù)源代碼：def secure_filename(filename: str) -> str: r'''Pass it a filename and it will return a secure version of it. This filename can then safely be stored on a regular file system and passed to :func:`os.path.join`. The filename returned is an ASCII only string for maximum portability. On windows systems the function also makes sure that the file is not named after one of the special device files. >>> secure_filename('My cool movie.mov') ’My_cool_movie.mov’ >>> secure_filename('../../../etc/passwd') ’etc_passwd’ >>> secure_filename(’i contain cool xfcmlxe4uts.txt’) ’i_contain_cool_umlauts.txt’ The function might return an empty filename. It’s your responsibility to ensure that the filename is unique and that you abort or generate a random filename if the function returned an empty one. .. versionadded:: 0.5 :param filename: the filename to secure ''' filename = unicodedata.normalize('NFKD', filename) filename = filename.encode('ascii', 'ignore').decode('ascii') for sep in os.path.sep, os.path.altsep:if sep: filename = filename.replace(sep, ' ') filename = str(_filename_ascii_strip_re.sub('', '_'.join(filename.split()))).strip('._' ) # on nt a couple of special files are present in each folder. We # have to ensure that the target file is not such a filename. In # this case we prepend an underline if (os.name == 'nt'and filenameand filename.split('.')[0].upper() in _windows_device_files ):filename = f'_{filename}' return filename

secure_filename(filename)函數(shù)修改后的代碼：

def secure_filename(filename: str) -> str: r'''Pass it a filename and it will return a secure version of it. This filename can then safely be stored on a regular file system and passed to :func:`os.path.join`. The filename returned is an ASCII only string for maximum portability. On windows systems the function also makes sure that the file is not named after one of the special device files. >>> secure_filename('My cool movie.mov') ’My_cool_movie.mov’ >>> secure_filename('../../../etc/passwd') ’etc_passwd’ >>> secure_filename(’i contain cool xfcmlxe4uts.txt’) ’i_contain_cool_umlauts.txt’ The function might return an empty filename. It’s your responsibility to ensure that the filename is unique and that you abort or generate a random filename if the function returned an empty one. .. versionadded:: 0.5 :param filename: the filename to secure ''' filename = unicodedata.normalize('NFKD', filename) filename = filename.encode('utf8', 'ignore').decode('utf8') # 編碼格式改變 for sep in os.path.sep, os.path.altsep:if sep: filename = filename.replace(sep, ' ') _filename_ascii_add_strip_re = re.compile(r’[^A-Za-z0-9_u4E00-u9FBFu3040-u30FFu31F0-u31FF.-]’) filename = str(_filename_ascii_add_strip_re.sub(’’, ’_’.join(filename.split()))).strip(’._’) # 添加新規(guī)則 # on nt a couple of special files are present in each folder. We # have to ensure that the target file is not such a filename. In # this case we prepend an underline if (os.name == 'nt'and filenameand filename.split('.')[0].upper() in _windows_device_files ):filename = f'_{filename}' return filename四、效果展示

我們很清楚的看到了效果，目前是支持中文的
