返回一個數據幀作為結果 Flask

Question

我用燒瓶。 我想返回一個數據幀作為結果。 但我收到這個錯誤。

TypeError: The view function did not return a valid response. The return type must be a string, dict, tuple, Response instance, or WSGI callable, but it was a DataFrame. 

Answer 1

將響應頭設置為text/csv

resp.headers["Content-Disposition"] = "attachment; filename=export.csv"
resp.headers["Content-Type"] = "text/csv"
return resp
