Python的代码：
@app.template_filter(‘date_format’) def _jinja2_filter_datetime_format(datetimeValue, format=u’%m月%d日’): “””convert a date to a different format.””” gLog.debug(“type(datetimeValue)=%s, datetimeValue=%s, format=%s”, type(datetimeValue), datetimeValue, format) # type(dateValue)=<type ‘builtin_function_or_method’>, dateValue=<built-in method date of datetime.datetime object at 0x7efccf27ea30>, format=%m月%d日 formattedDate = datetimeValue.strftime(format) gLog.debug(“type(formattedDate)=%s, formattedDate=%s”, type(formattedDate), formattedDate) return formattedDate |
结果出错：

datetime – UnicodeEncodeError when parsing month name with Python strptime – Stack Overflow
最后改为：
@app.template_filter(‘date_format’) # def _jinja2_filter_datetime_format(datetimeValue, format=u’%m月%d日’): def _jinja2_filter_datetime_format(datetimeValue, format=’%m月%d日’): “””convert a date to a different format.””” gLog.debug(“type(datetimeValue)=%s, datetimeValue=%s, format.decode(‘utf-8’)=%s”, type(datetimeValue), datetimeValue, format.decode(“utf-8”)) # type(dateValue)=<type ‘builtin_function_or_method’>, dateValue=<built-in method date of datetime.datetime object at 0x7efccf27ea30>, format=%m月%d日 # formatUtf8 = format.encode(“UTF-8”) # gLog.debug(“formatUtf8=%s”, formatUtf8) # formattedDate = datetime.strftime(datetimeValue, formatUtf8) formattedDate = datetime.strftime(datetimeValue, format) formattedDateUnicode = formattedDate.decode(‘utf-8’) gLog.debug(“type(formattedDate)=%s, formattedDateUnicode=%s”, type(formattedDate), formattedDateUnicode) return formattedDateUnicode |
即可：
