Node.js mongodb 设置默认安全变量



我正在尝试在本地运行 Node.js 脚本,它给了我以下错误消息:

========================================================================================
=  Please ensure that you set the default safe variable to one of the                  =
=   allowed values of [true | false | {j:true} | {w:n, wtimeout:n} | {fsync:true}]     =

这是我的变量:

var express = require('express');
var mongodb = require('mongodb');
var GridStore = require('mongodb').GridStore;
var Db = require('mongodb').Db;
var Server = require('mongodb').Server;
var db = new Db(Config.dbName, new Server("127.0.0.1", 27017, {}), {});    
var HttpGet = require('./httpGet').HttpGet;
var URL = require('url');
var dbClient = null; // this is initialized when db is opened
var app = module.exports = express();

相同的脚本在我的实时服务器上运行良好。它仅在我在本地运行时才会组合。

我发现在github上讨论了同样的问题,但没有找到解决方案。https://github.com/kissjs/node-mongoskin/issues/77

有谁知道什么可能导致这个问题?

提前致谢:)

以下内容适用于我使用 1.1.11 mongo 驱动程序:

var db = new Db(Config.dbName, new Server("127.0.0.1", 27017, {}), {safe: true});

如果没有 {safe: true} 参数,我确实会收到与您在问题中显示的相同的警告。

此警告是驱动程序的最新添加;您可能在服务器上使用了旧版本的驱动程序,这就是为什么您在那里看不到警告的原因。

我通过将strict模式设置为 false 来让它工作。

var db = new Db(config.dbName, new Server("127.0.0.1", 27017, {}), {safe: false, strict: false}); 
这对

我有用!

var db = new Db((new DbServer('127.0.0.1', 27017), {w:-2,journal:false,fsync:false,safe: false})
