本文的目的是介绍MongoDB 从请求中传递查询的详细情况，特别关注mongodb 或查询的相关信息。我们将通过专业的研究、有关数据的分析等多种方式，为您呈现一个全面的了解MongoDB 从请求中传递查询的机会，同时也不会遗漏关于57-1、2、3 NoSQL基础及MongoDB、MongoDB基本应用、mongodb索引及复制集、adminMongo:mongoDB node GUI(mongoDB图形化界面)、c# Mongodb 两个字段不相等 MongoDB 原生查询、Java MongoDB：com.mongodb.DB和com.mongodb.client有什么区别的知识。

• MongoDB 从请求中传递查询（mongodb 或查询）
• 57-1、2、3 NoSQL基础及MongoDB、MongoDB基本应用、mongodb索引及复制集
• adminMongo:mongoDB node GUI(mongoDB图形化界面)
• c# Mongodb 两个字段不相等 MongoDB 原生查询
• Java MongoDB：com.mongodb.DB和com.mongodb.client有什么区别

MongoDB 从请求中传递查询（mongodb 或查询）

因此@willis 建议执行以下操作

let query = {};

if (Array.isArray(req.query.product_type) && req.query.product_type.length > 0) {
    query["product_type.name"] =  {
        $in: req.query.product_type
    }
}

57-1、2、3 NoSQL基础及MongoDB、MongoDB基本应用、mongodb索引及复制集

02MongoDB基本应用

配置环境：

node1:192.168.1.121CentOS release 6.7

[root@node1 ~]# cd mongodb-2.6.4/

[root@node1 mongodb-2.6.4]# ls

adminMongo:mongoDB node GUI(mongoDB图形化界面)

获取项目项目
    克隆：git clone https://github.com/mrvautin/adminMongo.git
    也可以去下载ZIP包：https://github.com/mrvautin/adminMongo
2.切入项目

    cd adminMongo
3.安装依赖

    npm install
4.进行配置

    找到config/app.json添加以下配置：
                                    {
                                      "app": {
                                        "host": "0.0.0.0",       //IP（注意这里的配置是0.0.0.0，不是服务器IP，在linux不添加此配置，项目无法启动）
                                        "port": 1234,             //端口
                                        "username": "admin",      //用户名
                                        "password": "admin123456",//密码
                                        "locale": "en",           //语言，中文zh-cn
                                        "context": "dbApp",       //路由配置：例如：http://0.0.0.0:1234/dbApp
                                        "monitoring": true        //是否定期运行监视
                                      }
                                    }
        如若不添加以上配置系统默认监听1234端口，也不会有登录页面，
    访问直接进入系统。
    
    **注意：
            系统默认只能配置password，username配置后需要修改源代码。
                --：找到views/login.hbs文件（登录页面）

                                }else{
                                    // password is wrong. Show login form with a message
                                    res.render(''login'', {

                            }else{
                                res.redirect(req.app_context + ''/'');
                            }
    **：配置完成重新启动                        
5.启动

    node app  或者   npm start
    访问：
        http://xxx.xxx.xxx.xx:1234
    使用pm2守护进程：
            下载pm2:npm install pm2 -g
            进入项目目录 
            pm2 start app.js --name admin-mongo   # 启动应用，并为之命名
            pm2 list                              # 查看pm2管理的应用运行状态
            pm2 stop admin-mongo                # 停止应用
            pm2 delete admin-mongo              # 从pm2列表里删除应用    
6.登录

    添加了配置访问必须输入用户名，密码。

{ "TotalSecond",new BsonDocument(para,request.TotalMin * 60)}
};
var list= collection.Find(document);

其中 this 不能省略，写法同 mongodb 命令，使用此写法可以自由拼接参数

// 判断时间范围，单位：秒

var document = new BsonDocument{
{ "$where","this.StarTime-this.EndTime>10"},
{ "Closed",1},
{ "StarTime",new BsonDocument("$gte",request.Stime)},
{ "EndTime",new BsonDocument("$lte",request.Etime)},
{ "TotalSecond",new BsonDocument(para,request.TotalMin * 60)}
};
var list= collection.Find(document);
