D:\python>snmpwalk -v 2c -c public 127.0.0.1 .1.3.6.1.4.1.2021.5000

UCD-SNMP-MIB::ucdavis.5000.2.1.2.10.103.101.116.119.105.110.105.110.102.111 = STRING: "C:/test/test.ba

UCD-SNMP-MIB::ucdavis.5000.2.1.20.10.103.101.116.119.105.110.105.110.102.111 = INTEGER: 4
UCD-SNMP-MIB::ucdavis.5000.2.1.21.10.103.101.116.119.105.110.105.110.102.111 = INTEGER: 1

UCD-SNMP-MIB::ucdavis.5000.3.1.2.10.103.101.116.119.105.110.105.110.102.111 = STRING: "test123456"
UCD-SNMP-MIB::ucdavis.5000.3.1.3.10.103.101.116.119.105.110.105.110.102.111 = INTEGER: 1
UCD-SNMP-MIB::ucdavis.5000.3.1.4.10.103.101.116.119.105.110.105.110.102.111 = INTEGER: 0
UCD-SNMP-MIB::ucdavis.5000.4.1.2.10.103.101.116.119.105.110.105.110.102.111.1 = STRING: "test123456"

根据回显内容，修改oid，在原OID后添加上方标红ID，重新获取内容：

D:\python>snmpwalk -v 2c -c public 127.0.0.1 .1.3.6.1.4.1.2021.5000.3.1.1.10.103.101.116.119.105.110.105.110.102.111
UCD-SNMP-MIB::ucdavis.5000.3.1.1.10.103.101.116.119.105.110.105.110.102.111 = STRING: "test123456"

D:\python>

直接获取到所需内容行，接下来就是解析改行内容，再此之前，发现如果获取内容包含中文时，回显内容为“HEX-STRING:”，示例：

D:\python>snmpwalk -v 2c -c public 127.0.0.1 .1.3.6.1.4.1.2021.5000.3.1.1.10.103.101.116.119.105.110.105.110.102.111
UCD-SNMP-MIB::ucdavis.5000.3.1.1.10.103.101.116.119.105.110.105.110.102.111 = Hex-STRING: E6 B5 8B E8 AF 95 31 32 33 34 35 36

D:\python>

所以，我们需要对回显结果进行判断后解析，python脚本为：

# coding=utf-8
import re
import os,sys
import time
import platform

if 'Windows' == platform.system():
    hosts = ['127.0.0.1']
else:
    # 在虚拟机运行时则查看本地
    hosts = ['127.0.0.1']



def snmpWalk(host, oid):
    result = os.popen('snmpwalk -v 2c -c public ' + host + ' ' + oid).read()
    return result


#snmpwalk -v 2c -c public  127.0.0.1 .1.3.6.1.4.1.2021.5000
#处理回显结果system
def getSystem(host):
    system = snmpWalk(host, '.1.3.6.1.4.1.2021.5000.3.1.2.10.103.101.116.119.105.110.105.110.102.111')
    if system.find('Hex-STRING:') > 0: 
        system = "".join(system.split('Hex-STRING:')[1:])
        system = "".join(system.split('\n'))
        system = "".join(system.split(' '))
        system = system.decode("hex")
    
    else:
        system = "".join(system.split('STRING: \"')[1:])
        system = system[0:len(system)-2]
    return system

def main():
    for host in hosts:

        print('=' * 10 + host + '=' * 10)
        print(u"测试信息")
        system = getSystem(host)
        print system
        my_file = 'C:/test/snmpTestinfo'
        print ("信息存储到文件: %s"%(my_file)).decode('utf-8').encode('gbk')
        if os.path.exists(my_file):
            os.remove(my_file)
        f = open(my_file, 'a+')
        f.write(str(system))
        f.close()

if __name__ == '__main__':
    main()
