Question

我正在尝试设置一个nodejs服务器，并且无法通过邮递员从中获取响应

var express = require("express");
var app = express();
var bodyParser = require("body-parser");
var mongoose = require('mongoose');

//configure app for body parser   
app.use(bodyParser.urlencoded({extended: true}));
app.use(bodyParser.json);

//setup server port
var port = process.env.PORT || 2345;

//connect to DB
mongoose.connect('mongodb://localhost:27017/helloapi', {
    useMongoClient: true
});

//API routes
var router = express.Router();

//test routes
router.get("/", function (req, res) {
    res.json({message: "welcome to our api"});
});

//routs will all be with prefix /api
app.use('/api', router);

//fire up server
app.listen(port);

//print to console when server fireup
console.log("Server listening on port: " + port);

即时启动mongod及其工作正常，当我启动文件时，我甚至看到了这一点：

2017-12-12T13:34:21.828+0200 I NETWORK [conn11] received client metadata from 127.0.0.1:53090 conn: { driver: { name: "nodejs", version: "2.2.33" }, os: { type: "Windows_NT", name: "win32", architecture: "x64", version: "10.0.16299" }, platform: "Node.js v9.2.1, LE, mongodb-core: 2.1.17" }

但是当邮寄员发送http://localhost:2345/api/时我得不到任何回应

我在这里做错了什么？感谢

Answer 1

我发现了我使用的错误：

app.use(bodyParser.json);

然后我将其修复为：

app.use(bodyParser.json());

现在一切正常

需要帮助从nodejs api获得回复
