我有一個安裝程序,我試圖從控制檯註銷我的請求和從app.get('*',函數(req,我是新來表達和節點,並發現我的日誌出來undefined。快速請求和響應正文始終是一個空對象和Content-Type始終未定義
我已經閱讀了至少10 stackoverflow上的帖子,我的中間件解析器需要來路由之前和剛過應用程序的初始化。這是我在這裏做什麼。 任何人都知道是怎麼回事。
console.log("url = ", req.url, " req-body = ", req.body, "res-type = ", res.get('Content-Type'));
上面一行將返回REQ體區= {}和資源型=未定義
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);
});
只是爲了理解......你是否試圖從響應變量中獲取內容類型!?請求變量呢,在'req.headers'中呢? –
是的我試圖從響應中獲取內容類型。 req.headers給我提供數據。但想知道爲什麼我無法從請求中獲得任何身體數據。 –
你無法從get方法中獲取任何內容。嘗試將此更改爲'發佈'比'獲取'更好。 –
