Windows snmp++获取本地主机信息

本文主要是介绍Windows snmp++获取本地主机信息，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

编译snmp++的包

调用snmp++.lib实现信息获取_哔哩哔哩_bilibili

代码：

#include <iostream>
#include <libsnmp.h>
#include <vector>
#include <fstream>
#include <string>
#include "snmp_pp/snmp_pp.h"
//#define _NO_LOGGING
#ifdef WIN32
#define strcasecmp _stricmp
#endif#ifdef SNMP_PP_NAMESPACE
using namespace Snmp_pp;
#endifusing namespace std;
using namespace Snmp_pp;
typedef struct {string aa;string bb;string cc;
}CON;
vector<CON> readTxt(string path) {vector<CON> res;ifstream file(path);string line;CON a;getline(file, line);line = line.substr(line.find('=') + 1);a.aa = line;while (getline(file,line)){line= line.substr(line.find('=') + 1);a.bb = line;getline(file, line);line = line.substr(line.find('=') + 1);a.cc = line;res.push_back(a);}return res;
}
vector<string> getSnmpValue(vector<CON> a) {vector<string> res;int status;Snmp::socket_startup(); // Initialize the socket subsystem// Create an SNMP++ sessionSnmp snmp(status);if (status != SNMP_CLASS_SUCCESS){cout << "SNMP++ Session creation failed." << endl;return vector<string>();}for (int i = 0; i < a.size(); i++){// Set the target addressUdpAddress targetAddress(a[i].bb.c_str());// Create the target using the target address and community stringCTarget target(targetAddress);target.set_version(version2c); // Use SNMPv2ctarget.set_retry(3);           // Set the number of retriestarget.set_timeout(1000);      // Set the timeout (milliseconds)target.set_readcommunity(a[i].aa.c_str());// Create a PDU object for the SNMP GET requestPdu pdu;pdu.set_type(sNMP_PDU_GET);pdu += Vb(a[i].cc.c_str()); // Add the OID to retrieve// Send the SNMP GET requeststatus = snmp.get(pdu, target);if (status == SNMP_CLASS_SUCCESS){// Check the response PDU for errorsif (pdu.get_error_status() == SNMP_ERROR_SUCCESS){// Iterate through the received variable bindingsfor (int i = 0; i < pdu.get_vb_count(); i++){Vb vb;pdu.get_vb(vb, i);std::string value = vb.get_printable_value();res.push_back(value);  // 将值添加到容器中//cout << "OID: " << vb.get_printable_oid() << endl;//cout << "Value: " << vb.get_printable_value() << endl;}}else{cout << "Error in response PDU: " << endl;}}else{cout << "SNMP++ GET request failed: " << snmp.error_msg(status) << endl;}}Snmp::socket_cleanup(); // Shut down the socket subsystemreturn res;
}
