Question

我有reportSchema.js，这是定义我的架构的地方。我将从Microsoft Graph API返回的JSON存储到名为result的变量中。我想将result数组中的每个值存储到mongodb中。我可以像这样从数组访问单个项目

receivedDateTime: result.value[0].receivedDateTime,

sentDateTime: result.value[1].sentDateTime

但是我希望能够一次存储所有内容。我该怎么做呢？我将在下面发布代码。

reportSchema

 var mongoose = require('mongoose')

var sera = mongoose.Schema({
    isRead: Boolean,
    subject: String,
    from: String,
    receivedDateTime: Date,
    sentDateTime: Date
});

module.exports = mongoose.model("SERA", sera)

sample of result array

value: [{
            '@odata.etag': 'W/"CQAAAA=="',
            id: 'AAMkADg4MTBkNmRiLTAwNzQtNDE1Ny1hNjlkLWVjNzE5N2M1MGEwMgBGAAAAAAA9yT6uaq2hTrV0L6GqHQ_CBwALVVFnK27cQ4tC6FzqOc3cAAAAAAEMAAALVVFnK27cQ4tC6FzqOc3cAANuNGz-AAA=',
            receivedDateTime: '2019-03-09T03:45:45Z',
            sentDateTime: '2019-03-09T03:45:44Z',
            subject: 'Re: hw3',
            isRead: true,
            from: {
                emailAddress: {
                    name: 'Example',
                    address: 'example.yahoo.com'
                }
            }
        }]

how I am saving the report

   SERA.insertMany(result.value, function (error, success) {
                if (error) {
                    console.log("There has been an error inserting")
                } else {
                    console.log("The API data has been stored")
                }
            })
            // save stores into database
            SERA.save().then(result => {
                console.log(result)
            }).catch(function (error) {
                console.log("The error is " + error)
            });
            res.status(201).json({
                message: "Handling post request to /api/report",
                createdReport: report
            });

您可以使用insertMany（）接受要保存的值数组。

 var mongoose = require('mongoose')

 var sera = mongoose.Schema({
    isRead: Boolean,
    subject: String,
    from: {
      emailAddress: {
         name: String,
         address: String
      }
    },
    receivedDateTime: Date,
    sentDateTime: Date
 });

 const Sera = mongoose.model("SERA", sera)

 const values = [{
        id: 'AAMkADg4MTBkNmRiLTAwNzQtNDE1Ny1hNjlkLWVjNzE5N2M1MGEwMgBGAAAAAAA9yT6uaq2hTrV0L6GqHQ_CBwALVVFnK27cQ4tC6FzqOc3cAAAAAAEMAAALVVFnK27cQ4tC6FzqOc3cAANuNGz-AAA=',
        receivedDateTime: '2019-03-09T03:45:45Z',
        sentDateTime: '2019-03-09T03:45:44Z',
        subject: 'Re: hw3',
        isRead: true,
        from: {
            emailAddress: {
                name: 'Example',
                address: 'example.yahoo.com'
            }
        }
    }]

  Sera.insertMany(values, (error, docs) => {
    if(error) {
      console.log(error);
    } else {
      console.log(docs);
    }
  });

  // alternative
  // Sera.insertMany(values).then(docs => {
  //    console.log(docs)
  // })
  // .catch(error => {
  //   console.log(error)
  // })

一次存储Graph API中的所有项目
