Question

我正尝试从Mongoose的Mongodb获取一个带有以下代码的商品。在邮递员中发出带有ID的获取请求，以 http://localhost:5000/api/report/l5c959036c3dfe2338412be8e，返回的错误是

“ message”：“投射到ObjectId的值失败模型“报告”的路径“ _id”处的“ l5c959036c3dfe2338412be8e”

const express = require("express");
const app = express();
const mongoose = require("mongoose");
const cors = require("cors");
const bodyParser = require("body-parser");

mongoose.connect(
  "mongodb://localhost:27017/reports",
  { useNewUrlParser: true, useCreateIndex: true }
);
mongoose.connection.on(
  "error",
  console.error.bind(console, "connection error:")
);

app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));
app.use(cors());

app.get("/api/report/:id", (req, res) => {
  Report.findById(req.params.id, (err, report) => {
    if (err) return res.status(404).send({ message: err.message });
    return res.send({ report });
  });
});

感谢您的帮助！

按照注释中的建议，尝试从作为参数传递的objectId中删除“ I”。

找不到对findById
