我有一个 IRC 机器人，我正在尝试获取游戏服务器（GTA SA 多人游戏）的信息。我有现成的查询，但我无法在我的机器人中实现它。如果我尝试加载相同的脚本，但没有将其放入机器人的结构中，它会起作用。它给我的错误是

NameError：名称'ip'未定义

我尝试在 中添加 ip 地址作为参数def(inp,say=None)，但它仍然不起作用。那是代码：

from util import Query
from util import hook
import sys

@hook.command
def serverinfo(inp,ip="",port="",say=None):
    ip = "78.129.221.58"
    port = 7777 
if len(sys.argv) >= 3:
    ip = str(sys.argv[1])
    port = int(sys.argv[2])

query = Query(ip,port)
info = query.GetInformation()
say(info)
if info['players'] <= 100:
    say(query.GetPlayers())
    say(query.GetDetailedPlayers())
else: say('can\' get players because players is above 100')
say(query.Ping())
query.Close()

那是我导入的查询：

                output += [self.data.read(strlen)]
            except: break;
        return output

    def Close(self):
        self.sock.close()

有任何想法吗？

编辑：我做了一些更改后，给了我以下错误：

query = Query(ip,port)

TypeError：“模块”对象不可调用

我基本上已经更改了 ip 和端口的位置，将其移出 serverinfo 命令。

    from util import Query
from util import hook

ip = "78.129.221.58"
port = 7777
query = Query(ip,port)
info = query.GetInformation()

@hook.command
def serverinfo(inp,ip="",port="",say=None):
    say(info)
if info['players'] <= 100:
    say(query.GetPlayers())
    say(query.GetDetailedPlayers())
else: say('can\' get players because players are above 100')
say(query.Ping())
query.Close()

有问题的行是这一行：

query = Query(ip,port)

如果使用命令行参数初始化失败或传入的参数不足，ip将不会初始化导致上述错误。

此外，测试脚本的更好方法是这样的：

def main():
    if len(sys.argv) >= 3:
        ip = str(sys.argv[1])
        port = int(sys.argv[2])
        query = Query(ip,port)
        # start using query
    else:
        raise Exception("Insufficient args passed in")
if __name__ == '__main__':
    main()

引发异常/错误或打印出某些内容可以保证您知道传入的参数不足。另外，也许将所有代码移出到某个函数的开放位置？

尝试将此添加到 python 代码的开头：

ip = "78.129.221.58"
port = 7777

尝试

query = Query.Query(ip, port)
