我正在構建帶有節點js和net-snmp模塊的linux服務器監視。這部分是腳本來檢查存儲在mysql數據庫上的OID。我得到了問題,這個腳本總是隻執行最新的循環。我不知道爲什麼。這裏是我的代碼:使用循環但始終執行最新循環 - node.js net-snmp
connection.query("select * from SERVICE WHERE SERVER_ID = ? order by SERVICE_LIST_ID", [result[i].SERVER_ID], function(err2, services) {
if (err2) throw(err2);
//tapping services
for(var j in services){
session.get ([services[j].SERVICE_OID], function (error, varbinds) {
if (error) {
console.error (error);
} else {
//save services
console.log(j);
var post = {LOG_ID: result_logr.insertId, SERVICE_ID: services[j].SERVICE_ID, SERVICE_STATUS: 1};
var query = connection.query('INSERT INTO LOG_SERVICE SET ?', post, function(err, result) {
if (err) {
connection.rollback(function() {
throw err;
});
}
connection.commit(function(err) {
if (err) {
connection.rollback(function() {
throw err;
});
}
console.log('Transaction Complete.');
//connection.end();
});
});
console.log(query.sql);
}
});
}
});
而結果的顯示:
1
INSERT INTO LOG_SERVICE SET `LOG_ID` = 115, `SERVICE_ID` = 2, `SERVICE_STATUS` = 1
1
INSERT INTO LOG_SERVICE SET `LOG_ID` = 115, `SERVICE_ID` = 2, `SERVICE_STATUS` = 1
因此,它只能執行J = 1。 請幫幫我。謝謝
