当我从flask view函数将URL发送回javascript文件时，不会发生重定向，而是返回一个Type error: 'NoneType' object is not subscriptable。在

我的视图功能：@app.route('/login', methods=['POST','GET'])

def login():

if request.method == "POST":

print('check')

values = request.json

print(values)

result = db.session.query(Emp_Details).filter_by(ID=values['ID']).first()

print(result.Password)

if result.Password == values['Password'] and result.Department == 'HR':

print(jsonify(url=url_for('hr_department')))

return jsonify(url=url_for('hr_department'))

elif result.Password == values['Password'] and result.Department == 'DEVELOPMENT':

return url_for('devs')

else:

abort(401)

else:

return render_template("login.html")

我的Ajax请求：

^{pr2}$

控制台中的日志：check

{'Password': 'leechan2', 'ID': '10090'}
