项目使用的是 uwsgi + Django
from django.http import HttpResponse from openpyxl import Workbook, load_workbook from openpyxl.writer.excel import save_virtual_workbook class ExcelTableObj(object): def __init__(self, file_name=None, write_Only=False): if file_name: self.file_name = file_name self.wb = load_workbook(file_name) else: self.wb = Workbook(write_Only=write_only) self.write_Only= write_only def fix_save_excel(self, header, sheet_name, data_lists): ws = self.wb.create_sheet(title=sheet_name) ws.append(header) for data in data_lists: ws.append(data) # Django view excel = ExcelTableObj(write_Only=True) try: excel.fix_save_excel(title, sheetname, data_lists) except Exception as e: importtraceback as t; t.print_exc() logger.error(repr(e)) finally: respOnse= HttpResponse(save_virtual_workbook(excel.wb), content_type='application/vnd.openxmlformats-officedocument.spreadsheetml.sheet') response['Content-Disposition'] = 'attachment; filename={}'.format(filename) 因为 excel 文件很大, 所以使用write_only模式
- 安装了
lxml模块之后， 内存消耗稳定， 但是最后的文件打开异常
好像 uwsgi+lxml 会影响 openpyxl excel 文件的生成
- 不安装
lxml模块, 内存一直往上涨, 最后文件正常，但是太耗内存
请大佬帮忙看看原因， 以及可以优化的点， 非常感谢
感谢之前问题中 @superrichman 大佬的建议
