flask是python web開(kāi)發(fā)的常用框架之一。本文將講述flask如何實(shí)現(xiàn)修改密碼和免密登錄功能

修改密碼功能

數(shù)據(jù)庫(kù)部分：

#重置密碼
def reset_pass(phone,password):
    conn,cursor=get_conn()
    sql="update userdata set userpass='"+password+"' where userphone='"+phone+"'"
    try:
        print("正在修改密碼...")
        resetflag=cursor.execute(sql)
        conn.commit()
        close_conn(conn,cursor)
        if(resetflag==1):
            print("修改成功")
            return 1
        else:
            print("修改失?。?)
            return 0
    except:
        print("系統(tǒng)錯(cuò)誤...修改密碼失??！")
        return 0

路由部分：

#用戶修改密碼
@app.route('/resetpass',methods=['GET', 'POST'])
def resetpass():
    userphone=request.values.get('userphone')
    resetpass=request.values.get('resetpass')
    print("路由獲得手機(jī)號(hào)："+userphone+"\n")
    print("路由獲得新密碼：" + resetpass + "\n")
    flag=sql.reset_pass(userphone,resetpass)
    if(flag==1):
        return jsonify({"data":1})
    else:
        return jsonify({"data":0})
