用PYthon调用FLASK拆分PDF，网页一直报错
app.py：import os
import pathlib
import patoolib
from PyPDF2 import PdfFileReader, PdfFileWriter
from flask import Flask
from flask import render_template,request,send_file
app = Flask(__name__)
BASE_DIR = pathlib.Path()
@app.route('/',methods=["GET", "POST"])
def home():
if request.method == "POST":
file = request.files["pdf"]
pdf = PdfFileReader(file)
splitted = []
for i in range(pdf.getNumPages()):
w = PdfFileWriter()
w.addPage(pdf.getPage(i))
with open(BASE_DIR / "tmp" / f"{i+1}.pdf", 'wb') as out:
w.write(out)
splitted.append(f"tmp{i+1}.pdf")
patoolib.create_archive (f"tmp/pdf.zip", splitted)
return send_file(BASE_DIR /"tmp"/"pdf.zip", as_attachment=True)
return render_template("home.html")
app.run()
