Question

我有一个设置，我正在尝试通过app.get（'*'，函数（req，res，next）来控制注销我的请求和响应{。我是新来的表达和节点，我发现我的日志未定义。

我已经在stackoverflow上阅读了至少10篇帖子，我的中间件解析器需要在路由之前和应用初始化之后。这就是我在这里做的。任何人都知道这里发生了什么。

  console.log("url = ", req.url, "  req-body  = ", req.body,   "res-type  = ", res.get('Content-Type'));

上面的行将返回req-body = {}和res-type = undefined

    const path = require('path')
    const express = require('express')
    const bodyParser = require('body-parser');

    const host = 'localhost';
    const port = process.env.PORT || 3002;

    const app = express()
    app.use(bodyParser.json());
    app.use(bodyParser.text());
    app.use(bodyParser.urlencoded({ extended: true }));

    const indexPath = path.join(__dirname, '../index.html')
    const publicPath = express.static(path.join(__dirname, 'public'))

    // DEV SERVER WEBPACK API
    if (process.env.NODE_ENV !== 'production') {
      const webpack = require('webpack')
      const webpackDevMiddleware = require('webpack-dev-middleware')
      const webpackHotMiddleware = require('webpack-hot-middleware')
      const config = require('../webpack/webpack.dev.config.js')
      const compiler = webpack(config)

      // WEBPACK MIDDLEEWARE
      app.use(webpackHotMiddleware(compiler))
      app.use(webpackDevMiddleware(compiler, {
        noInfo: true,
        publicPath: config.output.publicPath,
        stats: { colors: true },
        historyApiFallback: true
      }))
    }

    // MIDDLEWARE FOR PRODUCTION TO SERVE FILES DIRECTLY FROM PUBLIC.
    app.use('/public', publicPath)

    // REQUEST CALLS.
    app.get('*', function (req, res, next) {
      console.log("url = ", req.url, "  req-body  = ", req.body,   "res-type  = ", res.get('Content-Type'));
      res.sendFile(indexPath);
    })

   app.listen(port, host, () =>{
     console.log("server ready on port  :", port, " and on host : ", host );
   });

也许这可以解决您的问题：

app.post('*', function (req, res, next) {
      console.log("url = ", req.url, "  req-body  = ", req.body,   "res-type  = ", res.get('Content-Type'));
      res.sendFile(indexPath);
    })

将get方法更改为post或put方法。

表达请求和响应主体始终是一个空对象，并且Content-Type始终未定义
