我是新来的pysnmp。在读取来自snmplabs.com的文档时，我尝试了get_command代码，但得到的输出是在超时之前没有收到SNMP响应

正如在回答一些类似类型的问题时所提到的，我尝试在代码的开头添加下面提到的内容。

代码语言：javascript
运行
复制
from pysnmp import debug
debug.setLogger(debug.Debug('io', 'msgproc', 'secmod'))

完整的代码如下所示

代码语言：javascript
运行

from pysnmp.hlapi import *
from pysnmp import debug

debug.setLogger(debug.Debug('io', 'msgproc', 'secmod'))

def getFunc(OID):
    errorIndication, errorStatus, errorIndex, varBinds = next(
        getCmd(SnmpEngine(),
               CommunityData('public', mpModel=0),
               UdpTransportTarget(('demo.snmplabs.com', 161)),
               ContextData(),
               ObjectType(ObjectIdentity('SNMPv2-MIB', OID, 0)))
    )

    if errorIndication:
        print(errorIndication)
    elif errorStatus:
        print('%s at %s' % (errorStatus.prettyPrint(),
                            errorIndex and varBinds[int(errorIndex) - 1][0] or '?'))
    else:
        for varBind in varBinds:
            print(' = '.join([x.prettyPrint() for x in varBind]))


if __name__ == "__main__":
    getFunc('sysName')

输出日志如下所示
