app.js
var url = require('url');
var http = require('http');
var fs = require('fs');
http.createServer(200, function(req, res){
var q = url.parse(req.url, true);
var filename = "." + q.pathname;
fs.readFile(filename, function(err, data){
if(err)
{
res.writeHead(404, {'Content-Type' : 'text/html'});
return res.end("404 Not Found!!!");
}
res.writeHead(200, {'Content-Type' : 'text/html'});
res.write(data);
return res.end();
});
}).listen(8080);
当我尝试使用命令" node app.js"运行它时,我收到以下错误:
events.js:238
throw new TypeError('"listener" argument must be a function');
^
TypeError: "listener" argument must be a function
at _addListener (events.js:238:11)

我试图找出解决方案,但无法解决问题。 提前谢谢。

只需删除200
,
检查以下代码
var url = require('url');
var http = require('http');
var fs = require('fs');
http.createServer(function(req, res){
var q = url.parse(req.url, true);
var filename = "." + q.pathname;
fs.readFile(filename, function(err, data){
if(err)
{
res.writeHead(404, {'Content-Type' : 'text/html'});
return res.end("404 Not Found!!!");
}
res.writeHead(200, {'Content-Type' : 'text/html'});
res.write(data);
return res.end();
});
}).listen(8080);

http.createServer
只需要function
,其中包含2个回调项(response, request)
。只需从createServer调用中删除200
或将其替换为:
http.createServer(function(req, res) { ... }
