Question

在制作一个简单的服务器并尝试测试虚拟路由的响应时，当我在chrome中运行它时，浏览器会无限旋转并且不会加载页面。

index.js

const express = require('express');
const bodyParse = require('body-parser');
const cors = require('cors');
const morgan = require('morgan');

const index = express();

// log formatter
index.use(morgan('combine'));
index.use(bodyParse.json);
index.use(cors());

index.get('/status', (req, res) => {
    res.send({
        message: 'herrrooo'
    })
});

index.listen(process.env.PORT || 5000);

的package.json

{
  "name": "server",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "start": "nodemon index.js",
    "dev": "concurrently \"npm run start\" "
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "dependencies": {
    "body-parser": "^1.18.3",
    "cors": "^2.8.4",
    "express": "^4.16.3",
    "morgan": "^1.9.0",
    "nodemon": "^1.17.5"
  },
  "devDependencies": {
    "@types/express": "^4.11.1",
    "concurrently": "^3.5.1",
    "eslint": "^4.19.1",
    "eslint-config-standard": "^11.0.0",
    "eslint-plugin-import": "^2.12.0",
    "eslint-plugin-node": "^6.0.1",
    "eslint-plugin-promise": "^3.8.0",
    "eslint-plugin-standard": "^3.1.0"
  }
}

我做错了什么？

Answer 1

改变这个：

index.use(bodyParse.json);

到此：

index.use(bodyParse.json());

你没有传递正确的中间件功能，所以当它到达那个中间件时表达被卡住，因为中间件从未调用next()来继续请求处理到下一步。
