我正在尝试使用 flask 和 mysql 创建一个 CRUD 应用程序。我尝试显示一个用于学生登录，一个用于教师登录。通过点击按钮“Std-Login”和“Teach-Login”显示表单。 当我在控制台上运行代码时，它显示 ----- 回溯(最近的通话丢失): @app.route('stdLog',methods=['POST','GET'] AssertionError: View 函数映射正在覆盖和现有端点函数:home

因为您正在覆盖现有端点函数:home
将路由/stdLog 函数更改为:def home2(): 或 def stdLog():
@app.route('/stdLog',methods=['POST','GET'])
def stdLog():
if request.method=='POST':
mycursor=mydb.cursor()
pwHash=bcrypt.generate_password_hash(request.form['password'])
sql="insert into student (name,password) values (%s,%s)"
val=(request.form['name'],pwHash)
mycursor.execute(sql,val)
mydb.commit()
print(mycursor.rowcount,"student's record inserted")
return 'ok'
希望对你有帮助。
