我通过的信息去了哪里？

我有这个节点的http服务器。

/** * Module dependencies. */ var http = require('http'), fs = require('fs'), cycle = require('./cycle.js'); /** * Create the server. */ var server = http.createServer(function (req, resp) { console.log(JSON.decycle(req) ); if ('GET' === req.method && '/images' === req.url.substr(0, 7) && '.jpg' === req.url.substr(-4) ) { fs.stat(__dirname + req.url, function (err, stat) { if (err || !stat.isFile() ) { res.writeHead(404); res.end('Not Found'); return; } serve(__dirname + req.url, 'application/jpg'); }); } else if ('GET' === req.method && '/' === req.url) { serve(__dirname + '/index.html', 'text/html'); } else { resp.writeHead(404); resp.end('Not found'); } function serve(path, type) { resp.writeHead(200, {'Content-Type': type}); fs.createReadStream(path).pipe(resp); } }); /** * Listen. */ server.listen(3000); 

（它使用Crockford的对象打印工具。https://github.com/douglascrockford/JSON-js/blob/master/cycle.js ）

当我点击这个请求时，我传递的信息不会出现在请求中。 为什么不？

 RickH$ curl -X POST -H "Content-Type: application/x-www-form-urlencoded" -H "Cache-Control: no-cache" -H "Postman-Token: 647062e3-bd38-edf0-3b3a-e56227daf94c" -d '&first_name=James&last_name=Taylor&city=Urbana&state=Illinois' "localhost:3000" RickH$ 

这是一个大型项目的简化版本。 在较大的项目中，请求被传送到另一个服务器，该服务器根据请求的内容作出反应。 所以我觉得我知道内容正在通过。 但是它在哪里？

后来 – – – – – – – –

 /********* Version 2 of server callback function. This one shows the full request body. var server = http.createServer(function (req, resp) { console.log(); console.log('=========================%=========================='); console.log(); console.log(JSON.decycle(req) ); req.rawBody = ''; req.setEncoding('utf8'); req.on('data', function (chunk) { req.rawBody += chunk; // next(); }); req.on('end', function () { console.log(); console.log('~~~~~~~~~~~~~~~~~~~~~~~~~+~~~~~~~~~~~~~~~~~~~~~~~~~~'); console.log(); console.log(JSON.decycle(req) ); // next(); }); if ('GET' === req.method && '/images' === req.url.substr(0, 7) && '.jpg' === req.url.substr(-4) ) { fs.stat(__dirname + req.url, function (err, stat) { if (err || !stat.isFile() ) { res.writeHead(404); res.end('Not Found'); return; } serve(__dirname + req.url, 'application/jpg'); }); } else if ('GET' === req.method && '/' === req.url) { serve(__dirname + '/index.html', 'text/html'); } else { resp.writeHead(404); resp.end('Not found'); } function serve(path, type) { resp.writeHead(200, {'Content-Type': type}); fs.createReadStream(path).pipe(resp); } }); *********/

你需要下面的代码来获得请求的正文（你的信息）

 var data; req.on('data', function(chunk){ data += chunk; }); req.on('end', function(){ console.log(data); });
