根据 json 文档为给定模式创建路由

Question

我想使用以下架构将数据保存在数据库中：

var mongoose = require('mongoose');
var Schema = mongoose.Schema;
var ObjectId = Schema.ObjectId;

// Task schema
var taskSchema = mongoose.Schema({

 tasktype  : {type: String},
 createdon : {type: Date, default: Date.now},
 createdby : {type: Schema.Types.ObjectId,ref: 'User'},
 visitedby : [{type: Schema.Types.ObjectId,ref: 'User'}],
 taskinfo  : [{ isactive:Boolean, taskobject:String, taskdetails:String, iscompleted:Boolean}]  

});
module.exports = mongoose.model('Task', taskSchema);

这里是json文档的链接：Link

[
  {
    "_id": "55f4e4f5fe8b36980a611519",
    "tasktype": "Basic",
    "__v": 0,
    "taskinfo": [
      {
        "isactive":"True" ,
        "taskobject": "paid",
        "taskdetails": "This is task one",
        "iscompleted": "False"
      },
      {
        "isactive": "False",
        "taskobject": "free",
        "taskdetails": "This is task two",
        "iscompleted": "False"
      },
      {
        "isactive": "True",
        "taskobject": "paid",
        "taskdetails": "This is task three",
        "iscompleted": "False"
      },
      {
        "isactive": "True",
        "taskobject": "free",
        "taskdetails": "This is task four",
        "iscompleted": "False"
      }
    ],
    "visitedby": [],
    "createdon": "2015-09-13T02:52:37.512Z"
  }
]

我想使用rest api在nodejs中编写路由（控制器），但我不知道如何使用mongoose在mongodb中保存数组字段。

如果你能推荐我很好的资源，因为我买了一些 udemy 课程，但导师只告诉了 fieldname: res.body.fieldname 来接受用户输入 在这种情况下，这对我不起作用。

如果你能告诉我如何在我的数据库中保存数组，那就太好了，

这是不正确的示例路由文件，请帮助我

var Task     = require ('../models/task');
var User       = require ('../models/user');
var config     = require ('../../config');
module.exports = function(app, express) {

    var api = express.Router();

  api.post('/tasks', function (req, res) {
    var task = new Task({

          tasktype  : req.body.tasktype,
          taskinfo  : req.body.taskinfo,
      }); 

     task.save(function(err){
        if(err){
           res.send(err);
        return;
        }
       res.json({message:'Task has been created'})
      });
return api
}

  "name": "todotask",
  "version": "1.0.0",

}

从客户端发送此类数据

taskinfo:[{
        "isactive":"True" ,
        "taskobject": "paid",
        "taskdetails": "This is task one",
        "iscompleted": "False"
      },{
        "isactive": "False",
        "taskobject": "free",
        "taskdetails": "This is task two",
        "iscompleted": "False"
      }]

从客户端站点使用邮递员（谷歌应用程序）发送此数据。如果有任何错误，请粘贴该错误
