Express:POST请求后,Req.body未定义

Question

我在app.router之前使用了express.bodyParser(),并且标题似乎是正确的,但我仍然在req.body上未定义:

var app = express();
...

app.use(express.bodyParser());
...
app.use(app.router);

req.headers的输出是这样的:

{ host: '127.0.0.1:3000',
  connection: 'keep-alive',
  'content-length': '0',
  'cache-control': 'max-age=0',
  accept: 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
  origin: 'http://127.0.0.1:3000',
  'user-agent': 'Mozilla/5.0 (Windows NT 6.2; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/29.0.1547.76 Safari/537.36',
  'content-type': 'application/x-www-form-urlencoded',
  referer: 'http://127.0.0.1:3000/register',
  'accept-encoding': 'gzip,deflate,sdch',
  'accept-language': 'es-ES,es;q=0.8' }

帖子声明如下:

app.post('/register/do', function(req, res) {
    ...
    console.log(req.headers);
    console.log(req.body);
    ...
});

我究竟做错了什么？

Answer 1

你明白了Content-Length: 0，所以问题出在客户端。您的 Express 代码看起来没问题。
