XlsxWriter对象保存为http响应以在Django中创建下载

Question

XlsxWriter对象保存为http响应以在Django中创建下载？

Answer 1

关于Python 3的@alecxe响应(io.BytesIO而不是StringIO.StringIO)和Django> = 1.5(content_type而不是mimetype)的一点点更新,完全内存中的文件程序集已经由@jmcnamara实现({ 'in_memory':真的})!
这是完整的例子:

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"

    output.close()

    return response

Answer 2

我想你正在询问如何在内存中创建一个excel文件xlsxwriter并通过它返回HttpResponse.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.

Answer 3

说到Django,你甚至可以没有整个StringIO恶作剧.HttpResponse在这方面就像StringIO一样:

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}或者您可能获得HttpResponse has no attribute seek().谢谢@Jeb
