I want to give xlsx on request. With using BytesIO and xlsxwriter I create a file.
Using the code below, I can download an empty(!) .txt file:
@router.get("/payments/xlsx", response_description='xlsx')
async def payments():
"""sss"""
output = BytesIO()
workbook = xlsxwriter.Workbook(output)
worksheet = workbook.add_worksheet()
worksheet.write(0, 0, 'ISBN')
worksheet.write(0, 1, 'Name')
worksheet.write(0, 2, 'Takedown date')
worksheet.write(0, 3, 'Last updated')
workbook.close()
output.seek(0)
return StreamingResponse(output)
If I add headers={'Content-Type': 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet'} I get this error in browser:
Unable to open file
You may be having a problem connecting with the server, or the file that you wanted to open was corrupted.
How I can fix this?
You have to set Content-Disposition header in the response
@router.get("/payments/xlsx", response_description='xlsx')
async def payments():
output = BytesIO()
workbook = xlsxwriter.Workbook(output)
worksheet = workbook.add_worksheet()
worksheet.write(0, 0, 'ISBN')
worksheet.write(0, 1, 'Name')
worksheet.write(0, 2, 'Takedown date')
worksheet.write(0, 3, 'Last updated')
workbook.close()
output.seek(0)
headers = {
'Content-Disposition': 'attachment; filename="filename.xlsx"'
}
return StreamingResponse(output, headers=headers)
