我尝试生成在Excel中正确打开的CSV,但使用的是StringIO而不是文件。
output = StringIO("\xef\xbb\xbf") # Tried just writing a BOM here, didn't work
fieldnames = ['id', 'value']
writer = csv.DictWriter(output, fieldnames, dialect='excel')
writer.writeheader()
for d in Data.objects.all():
writer.writerow({
'id': d.id,
'value': d.value
})
response = HttpResponse(output.getvalue(), content_type='text/csv')
response['Content-Disposition'] = 'attachment; filename=data.csv')
return response
这是Django视图的一部分,所以我真的不愿意为此倾销临时文件。
我还尝试过以下方法:
response = HttpResponse(output.getvalue().encode('utf-8').decode('utf-8-sig'), content_type='text/csv')
没有运气
如何使用BOM在utf-8-sig
中正确编码输出文件,以便Excel打开文件并正确显示多字节unicode字符?
答案 0 :(得分:4)
HttpResponse
接受bytes
:
output = StringIO()
...
response = HttpResponse(output.getvalue().encode('utf-8-sig'), content_type='text/csv')
或让Django进行编码:
response = HttpResponse(output.getvalue(), content_type='text/csv; charset=utf-8-sig')
