NodeJS获取发布的数据 – 没有框架

假设我想要将已发布的数据写入/completed情况下的variables。 我该怎么办？ 我能够将数据检索到request.on（“data”…），但如果我将datalogging到我的/completed案例中， data是空的。

 var http = require('http'); http.createServer( function(request, response) { var data = ""; if(request.method == 'POST') { request.on('data', function(chunk) { console.log('Received data:', chunk.toString()); data += chunk.toString(); }); request.on('end', function() { console.log('Complete data:', data); }); } switch (request.url) { case "/": response.writeHead(200, {'Content-Type': 'text/html'}); response.write("<a href='/form'>Go to form</a>"); response.end(); break; case "/form" : response.writeHead(200, {'Content-Type': 'text/html'}); response.write("<form method='POST' action='/completed'>"); response.write("<input type='text' name='data1'/><hr/>"); response.write("<input type='text' name='data2'/><hr/>"); response.write("<input type='text' name='data3'/><hr/>"); response.write("<input type='file' name='data4'/><hr/>"); response.write("<input type='submit' value='Send'/>"); response.end("</form>"); break; case "/completed": console.log(request); response.writeHead(200, {'Content-Type': 'text/html'}); // var post = ? response.end(); break; default: response.writeHead(403, {'Content-Type': 'text/html'}); response.end("Forbidden"); break; } }).listen(1337); 

结果

 Received data: data1=dfs&data2=ds&data3=dvbcfgxrtgdw Complete data: data1=dfs&data2=ds&data3=dvbcfgxrtgdw

您可以：

 app.use(express.bodyParser()); app.post('/completed', function(request, response){ console.log(request.body.user.name); console.log(request.body.user.email); }); 

假设你使用快递。

否则，您将不得不使用req.on数据和结束事件：

 if (req.method == 'POST') { console.log("POST"); var body = ''; req.on('data', function (data) { body += data; console.log("Partial body: " + body); }); req.on('end', function () { console.log("Body: " + body); }); res.writeHead(200, {'Content-Type': 'text/html'}); res.end('post received'); } 

您还可以添加：

 qs = require('querystring'); var json = qs.parse(body); util.log("json: " + json); 

检索参数。

Express是非常有用的，我喜欢用它来避免这种types的代码处理。
