如何侦听http模块中没有“/”的路径

当http请求如下所示时,我可以触摸我的代码:

POST /init HTTP/1.1  
Host: 127.0.0.1  
Connection: keep-alive  
Content-Length: 1343 

POST init HTTP/1.1 // what different is : the path without a '/'  
Host: 127.0.0.1  
Connection: keep-alive  
Content-Length: 1343  

我的node.js代码是:

http.createServer(function (req, res) {
  console.log('sth')
}).listen(3000); 

不幸的是,我无法更改发出 init 要求
