新人求助 url.parse( ).path 无法使用

var server=http.createServer(function(req,res) { var post = ''; var raw_url = req.url; var url = url_parser.parse(raw_url,true); var pathname = url.pathname; var path = url.path; //url.path无法使用

//响应OneNet发来的请求，接收数据
if(pathname == '/dataPort')
{
           //已省略
}

// if(path == '/index') { res.writeHead(200,{'Content-Type':'text/html'}); fs.readFile('./index.html','utf-8',function(err,data) { res.write(data); res.end(); }); } //响应'/?test=ajax' else if(path == '/?test=ajax') { console.log('start ajax'); res.writeHead(200,{'Content-Type':'text/plain','Access-Control-Allow-Origin':'*'}); var jlatitude_json = {"man":man,"car":car}; var str = JSON.stringify(jlatitude_json); res.write(str); res.end(); } });

server.listen(80); console.log('server running at port 80');
