print("%s" % (time.time() - start_time))文件中的此代码出现错误：
route.py这是错误：
TypeError：预期的字符串或缓冲区
我正在使用VM virual box linux，这是 if user and bcrypt.check_password_hash(user.password,
request.form.get('password')):
文件：
route.py这是from flask import Flask, render_template,request,flash,redirect, url_for
from blog import app, db, bcrypt, login_manager
from flask_login import login_user, login_required, current_user, logout_user
from .models import User
@app.route('/login', methods=['GET', 'POST'])
def login():
if request.method=="POST":
user = User.query.filter_by(username=request.form.get('username')).first()
# This line make an error
if user and bcrypt.check_password_hash(user.password,
request.form.get('password')):
login_user(user)
flash('Logged in successfully','success')
next = request.args.get('next')
return redirect(next or url_for('dashboard'))
flash('Wrong password try again','danger')
return render_template('admin/login.html')
@app.route('/dashboard')
def dashboard():
return "Thank for register"
