Question

我有一个服务器编写NodeJS，后端设置就像这样

app.use(express.static(__dirname))

app.get('/', function(req, res){
  res.send('main page here')
});

app.get('/*', function(req, res){
  res.send('404 dude')
});

app.use(function(err, req, res, next){
  console.error(err.stack);
});

当我在/%点击我的服务器时，我得到了这个堆栈跟踪：

Error: Bad Request
    at SendStream.error (/Users/danielchao/code/node/node_modules/express/node_modules/send/index.js:239:16)
    at SendStream.pipe (/Users/danielchao/code/node/node_modules/express/node_modules/send/index.js:411:32)

    at next (/Users/danielchao/code/node/node_modules/express/lib/router/index.js:189:10)

为什么我的静态资产处理程序错误？理想情况下，这应该作为404来处理。
