XlsxWriter对象保存为http响应以在Django中创build下载

XlsxWriter对象保存为http响应，以在Django中创build下载？

Answer 1

我想你问的是如何使用xlsxwriter在内存中创build一个Excel文件，并通过HttpResponse返回。 这是一个例子：

 try: import cStringIO as StringIO except ImportError: import StringIO from django.http import HttpResponse from xlsxwriter.workbook import Workbook def your_view(request): # your view logic here # create a workbook in memory output = StringIO.StringIO() book = Workbook(output) sheet = book.add_worksheet('test') sheet.write(0, 0, 'Hello, world!') book.close() # construct response output.seek(0) response = HttpResponse(output.read(), mimetype="application/vnd.openxmlformats-officedocument.spreadsheetml.sheet") response['Content-Disposition'] = "attachment; filename=test.xlsx" return response 

希望有所帮助。

对于Python 3（ io.BytesIO，而不是StringIO.StringIO ）和Django> = 1.5（ content_type，而不是mimetype ）的@alecxe响应的一点更新，完整的内存文件组合已经由@jmcnamara 'in_memory'：True} ）！
这里是完整的例子：

 import io from django.http.response import HttpResponse from xlsxwriter.workbook import Workbook def your_view(request): output = io.BytesIO() workbook = Workbook(output, {'in_memory': True}) worksheet = workbook.add_worksheet() worksheet.write(0, 0, 'Hello, world!') workbook.close() output.seek(0) response = HttpResponse(output.read(), content_type="application/vnd.openxmlformats-officedocument.spreadsheetml.sheet") response['Content-Disposition'] = "attachment; filename=test.xlsx" return response 

Answer 3

说到Django，甚至可以不用整个StringIO shenanigans。 在这方面HttpResponse行为就像一个StringIO：

 from django.http import HttpResponse from xlsxwriter.workbook import Workbook def your_view(request): # your view logic here # create the HttpResponse object ... response = HttpResponse(content_type='application/vnd.openxmlformats-officedocument.spreadsheetml.sheet') response['Content-Disposition'] = "attachment; filename=test.xlsx" # .. and pass it into the XLSXWriter book = Workbook(response, {'in_memory': True}) sheet = book.add_worksheet('test') sheet.write(0, 0, 'Hello, world!') book.close() return response 

附录：您需要指定{'in_memory': True}否则您可能会得到HttpResponse has no attribute seek() 。 谢谢@Jeb
