node.js - 使用 post api 将数据保存到 mongodb

Question

我的 api 文件中有一个 post 函数。我想使用此帖子请求在 mongodb 数据库中保存电子邮件:

rest-api/emails?from="test@mail.com"&"to"="test@test.com"&subject="some subject"&content="some more content"&provider=sendgrid&success=false

我的帖子方法如下:

.post((req, res)=>{

  db.models.Email.create({from:req.body.from ,
                          to: req.body.to,
                          subject: req.body.subject,
                          content: req.body.content,
                          success: req.body.success,
                          provider: req.body.provider}, (err, result)=>{
    if(err){
      handleErrors(res, err);
      console.log(`error in creating Email :${err}`)
    }else {
      console.log()
      res.json(result)
    }
  });
});

在此发布请求之后，仅 _id、success、provider 字段保存在 mongodb 中。我该如何解决这个问题？

编辑:我从发布请求中删除了所有“但仍然无法正确保存:

localhost:3000/rest-api/emails?from=example@example.com&to=test@test.com&subject=somesubject&content=somemorecontent&provider=sendgrid&success=false

资源:

{
    "__v": 0,
    "_id": "599add615fcb202b34c6a13e",
    "success": false,
    "provider": "sendgrid"
}

编辑:型号:

var ValidationError = mongoose.Error.ValidationError;
var Schema = mongoose.Schema;

mongoose.Promise = global.Promise ;

var validateEmail = function(email) {
    if (email) return validator.isEmail(email);
    return true;
}

var EmailSchema = new Schema({
      from: {type: String, maxlength:100},
      to: {type: String, maxlength:100},
      subject: {type: String},
      content: {type: String},
      provider: {type: String, maxlength: 30, required: false, default: "sendgrid"},
      sentdate: { type: Date },
      success: {type: Boolean, default: false}
});
EmailSchema.pre('save',(next)=>{
  // if(!this.sentdate){
  //   this.sentdate = Date.now();
  // }
  next();
});

EmailSchema.plugin(mongoosePaginate);
var Email = mongoose.model('Email',EmailSchema);




module.exports ={
  models:{
    Email
  },
  url: 'mongodb://localhost/emilapp',
}

req.body 控制台:{}请求正文为空!

req.body 用于在您以 GET 请求发送数据时用于发布请求数据。发送到 Express 服务器的查询字符串存储在 req.query 对象中。您需要将我们的代码修改为如下所示。

.post((req, res)=>{

  db.models.Email.create({from:req.query.from ,
                          to: req.query.to,
                          subject: req.query.subject,
                          content: req.query.content,
                          success: req.query.success,
                          provider: req.query.provider}, (err, result)=>{
    if(err){
      handleErrors(res, err);
      console.log(`error in creating Email :${err}`)
    }else {
      console.log()
      res.json(result)
    }
  });
});
