这是我的文件，我该如何存储？？？在此处输入图像描述。我只能为一个文档编写 REST Api，但不能为多个文档编写。我正在使用 POSTMAN 调用服务。

您可以像这样创建架构：

var Mongoose = require('mongoose'),
    Schema = Mongoose.Schema;

var SchemaName = new Schema({
    email: { type: String }
});

var CollectionName = Mongoose.model('CollectionName', SchemaName);

您可以使用此示例一次插入多条记录。

var obj=[{
    email:"test@gmail.com"
},
{
    email:"test1@gmail.com"
},
{
    email:"test2@gmail.com"
}];

CollectionName.insertMany(obj)
.then(function(res) {
    console.log("=============insert===", res)
})
.
catch(function(err){
    console.log("============err nins===", err)
});

所以你想一次插入多个文档。

在 mongodb 中，一次可以保存的文档有一些限制。它可以支持高达 16MB 的 BSON 文档大小。在这里看到。

现在让我们一次讨论insertMany 个文档。

以下查询一次插入多个 dicuments：

db.CollectionName.insertMany(
   [ <document 1> , <document 2>, ... ],
   {
      ordered: <boolean[Default True]>
   }
);

现在 [ <document 1> , <document 2>, ... ]你可以通过你的文件了。以对象数组格式（如您所给）。
