Nodejs reported an error

  node.js, question

I just started to learn nodejs, an example I saw in the book, but I always reported my own mistakes.
Code:
req.addListener(‘end’,function(){
var retData = getDns(postData,function(domain,addresses){
res.writeHead(200,{‘Content-Type’:’text/html’});
res.end(‘<html>
<head>

</head>
<body>

Domain:“plus domainplus”
IP:Add addresses.join (‘,’) add’

</body>
</html>’);
});
Error reporting:
res.end(‘<html>
^^^^^^^
SyntaxError: Unexpected token ILLEGAL

The parameters in res.end do not wrap
A mistake was reported when parsing the grammar. It should be a grammatical problem.
