如何在AsyncCommandGenerator中进行多个GETNEXT查询？

from pysnmp.entity.rfc3413.oneliner import cmdgen
def cbFun(sendRequestHandle, errorIndication, errorStatus, errorIndex, varBinds, cbCtx):
    print varBinds

def main():
    ip = '127.0.0.1'
    cmdGen = cmdgen.CommandGenerator()
    errorIndication, errorStatus, errorIndex, varBinds = cmdGen.nextCmd(
        cmdgen.CommunityData('mymypub')
        cmdgen.UdpTransportTarget((ip, 161)),
        '1.3.6.1.2.1.17.7.1.2.2.1.2')
    #varBinds have about 200 elements
    print varBinds

    cmdGen = cmdgen.AsynCommandGenerator()
    cmdGen.asyncNextCmd(
        cmdgen.CommunityData('mymypub'),
        cmdgen.UdpTransportTarget((ip, 161)),
        ((1,3,6,1,2,1,17,7,1,2,2,1,2),),
        (cbFun, ip))
    cmdGen.snmpEngine.transportDispatcher.runDispatcher()
    #varBinds have 1 element
if __name__ == '__main__':
    main()

发电机中的所有元素。但我在AsyncCommandGenerator中只有一个元素。我怎么才能把它们都弄到手？在

Answer 1

要执行另一个GETNEXT，cbFun（）应该通过返回True来请求它。否则，AsyncCommandGenerator将不执行下一个GETNEXT。在
