出現"Most middleware (like bodyParser) is no longer bundled with Express"錯誤怎么解決
命令行里選定指定路徑然后輸入 node app.js?
會提示:

bodyParser.urlencoded(options)
Returns middleware that only parses?urlencoded?bodies. This parser accepts only UTF-8 encoding of the body and supports automatic inflation of?gzip?and?deflate?encodings.
A new?body?object containing the parsed data is populated on the?request?object after the middleware (i.e.req.body). This object will contain key-value pairs, where the value can be a string or array (when?extended?isfalse), or any type (when?extended?is?true).
Options
The?urlencoded?function takes an option?options?object that may contain any of the following keys:
extended
The?extended?option allows to choose between parsing the URL-encoded data with the?querystring?library (when?false) or the?qs?library (when?true). The "extended" syntax allows for rich objects and arrays to be encoded into the URL-encoded format, allowing for a JSON-like experience with URL-encoded. For more information, pleasesee the qs library.

bodyParser.urlencoded 中設置 extended 為 true 和為 false 有什么區別嗎？

按照樓上大哥?說的倒是能跑通了，但是后面提交數據的時候需要將?extended:?false?改為 extended:?true 否則會報錯： TypeError:?Cannot?read?property?'_id'?of?undefined 相關資料： 通常?POST?內容的格式是?application/x-www-form-urlencoded,?因此要用下面的方式來使用： app.use(require('body-parser').urlencoded({extended:?true})) 見： https://github.com/expressjs/body-parser2015-01-08
首先翻譯這句英文，大概的意思就是新版的express中已經不包含bodyparser了，那就需要大家單獨安裝bodyparser，安裝命令是npm install body-parser,然后在app.js中加載body-parser模塊var bodyParser = require('body-parser')，把app.use(express.bodyParser())替換成app.use(bodyParser.urlencoded({ extended: false }))，這樣調試就沒問題了。
