使用fs.readFileSync（）服务html文件失败

Question

I have this code ( https://gist.github.com/2402116 ) :

server.get('/', function(request, response) {
 var k = fs.readFileSync('./index.html','utf8');
 response.send( k );
});

Tries to read this file:

https://gist.github.com/2402070

and the browser keeps loading and never end.

But if I remove all the js includes from the html file works fine.

what am I doing wrong?

Answer 1

Your current server implementation does not do anything but serve index.html to requests for the base url, ie '/' . You will need to write further code/routes to serve the requests for the js includes in your index.html , ie '/app.js' and the various js files in '/js/' .

Now, the routing implementation in the gist is quite crude and doesn't support many aspects of url matching. The original code is clearly just demonstrating a concept for a single page site with no resources. You will see it will quickly become burdensome to get your code working as you will effectively have to write a route for every resource request, eg

server.get('/app.js', function(request, response) {
  var k = fs.readFileSync('./app.js','utf8');
  response.send( k );
});

server.get('/js/jquery-1.7.2.js', function(request, response) {
  var k = fs.readFileSync('./js/jquery-1.7.2.js','utf8');
  response.send( k );
});

etc...

You are better off looking at a node.js url routing library already out there (eg director ) or a web framework such as express which has inbuilt support for routing (and static file serving).

Answer 2

You need a response.end() once you are done sending data to your browser.

Actually, since you are sending all of your data at once, you can just replace response.send(k) with response.end(k) . Although this method is not recommended. I highly recommend reading your file asynchronously and sending it to the client chunk-by-chunk.

Answer 3

try .toString on k and not send but .end

response.end( k.toString() ); 

maybe some wierd things happens and he tries to eval the code
