Question

我不知道我可以使用.Router()来做到这一点。我刚够getById 我需要在POST请求上创建路由，是吗？

./ generalRepository.js

function Repository() {}

Repository.prototype.getById = getById;

function getById(id, callback) {
  var model = this.model;
  var query = model.findOne({
    _id: id
  });
  query.exec(callback);
}

.routers / user.js

const router = require("express").Router();
const userService = require("../../services/user");



router.get("/:id", (req, res, next) => {
  userService.findOne(String(req.params.id), (err, data) => {
    if (!err) {
      res.data = data;
      console.log("это запрос в айди");
      res.json(res.data);
    } else {
      console.log(Number(req.params.id));
      res.status(400);
      res.end();
    }
  });
});
module.exports = router;

.services / user.js

module.exports = {
  findAll: callback => {

  findOne: (id, callback) => {
    UserRepository.getById(id, (err, data) => {
      callback(err, data);
    });
  }
};

将数据发布到Node并使用Mongoose插入数据的简单示例：

// Add these two lines so your request's body can be accessed as JSON using req.body :
const bodyParser = require("body-parser");
app.use(bodyParser.json({ limit: '1mb' }));

(new myMongooseModel(req.body)).save( (error, result) => {
      if(error) return res.json(error);
      res.json(result);
})

我如何通过POST请求和Express的猫鼬添加新对象？
