Python 类型错误：'；会议'；对象不支持项分配

我使用Flask会话来确定是否有人登录到某个站点，但当我尝试为其赋值时，它返回错误“TypeError:“Session”对象不支持项赋值”

谢谢你的帮助

您可以使用此示例

 @app.route("/login",methods = ["POST","GET"])  
    def login():  
        if request.method == "POST":  
            try:   
                Email = request.form["email"]
                pwd = request.form["pwd"]    
                with sqlite3.connect("Account.db") as con:  
                    cur = con.cursor()
                    print("Connection test")   
                    cur.execute("SELECT * FROM Account WHERE Email= ? and Password= ?",(Email, pwd))
                    row = cur.fetchone()
                    print("query test")  
                    while row is not None:
                        session['email']=request.form['email']  
                        print(row[1])
                        return render_template("success.html",msg = msg)
                    else:
                        msg = "sorry wrong id"
                        return render_template("failure.html",msg = msg)
            except:  
                con.rollback()  
                msg = "problem"  

然后在另一个函数中

 if 'email' in session:
        email = session['email']   
        return render_template("view.html") 
    else:
        return '<p>Please login first</p>'  

如果会话中出现“电子邮件”：
电子邮件=会话['email']
返回渲染模板（“view.html”）
其他：
返回“请先登录”

如果您正在使用flask，您可以使用我提供的代码

 if 'email' in session:
        email = session['email']   
        return render_template("view.html") 
    else:
        return '<p>Please login first</p>'
