Node.js服务器“404未找到”消息到404.html页面 [英] Node.js server "404 not found" message to 404.html page

问题描述

我正在使用node.js，我想知道如何显示404.html而不是404 Not Found消息。

这是我的server.js：

  var http = require（http），
 url = require（url） ，
 path = require（path），
 fs = require（fs）
 port = process.argv [2] || 8888; 
 
 http.createServer（function（request，response）{
 
 var uri = url.parse（request.url）.pathname 
，filename = path.join （process.cwd（），uri）; 
 
 path.exists（filename，function（exists）{
 if（！exists）{
 response.writeHead（404，{ Content-Type：text / plain}）; 
 response.write（404 Not Found \\\
）; 
 response.end（）; 
 return; $ b （fs.statSync（filename）.isDirectory（））filename + ='public / Index / index.html'; 
 
 fs.readFile（filename ，binary，function（err，file）{
 if（err）{
 response.writeHead（500，{Content-Type：text / plain}）; 
 response.write（err +\ n）; 
 response.end（）; 
 return; 
} 
 
 response.writeHead（200）; 
 response.write（file，binary）; 
 response.end（）; 
}）; 
}）; 
}）。listen（parseInt（port ，10））; 
 $ b console.log（静态文件服务器运行在\\\
 => http：// localhost：+ port +/ \ nCTRL + C关闭）; 
  

你可以看到它只是一个静态文件服务器，我没有使用express.js或任何东西。

解决方案

p>

  response.writeHead（404，{Content-Type：text / plain}）; 
 response.write（404 Not Found \\\
）; 
 response.end（）; 
  

您可以更改为

  response.writeHead（404，{Content-Type：text / html}）; 
 response.write（HTMLDATA）; 
 response.end（）; 
  

'HTMLDATA'既可以是HTML的字符串，也可以是对您已经收集到的文件。
$ b response.writeHead（）总是在响应之前设置.write（）。

另请参阅我们已将响应类型设置为'text / html'

Im working with node.js and I would like to know how to display a 404.html instead of a "404 Not Found" message.

This is my server.js:

var http = require("http"),
url = require("url"),
path = require("path"),
fs = require("fs")
port = process.argv[2] || 8888;

http.createServer(function(request, response) {

var uri = url.parse(request.url).pathname
, filename = path.join(process.cwd(), uri);

path.exists(filename, function(exists) {
if(!exists) {
  response.writeHead(404, {"Content-Type": "text/plain"});
  response.write("404 Not Found\n");
  response.end();
  return;
}

if (fs.statSync(filename).isDirectory()) filename += 'public/Index/index.html';

fs.readFile(filename, "binary", function(err, file) {
  if(err) {        
    response.writeHead(500, {"Content-Type": "text/plain"});
    response.write(err + "\n");
    response.end();
    return;
  }

  response.writeHead(200);
  response.write(file, "binary");
  response.end();
  });
 });
}).listen(parseInt(port, 10));

console.log("Static file server running at\n  => http://localhost:" + port + "/\nCTRL + C to shutdown");

as you can see its just a static file server and I'm not using express.js or anything.

解决方案

H i ,

within your 404 case

  response.writeHead(404, {"Content-Type": "text/plain"});
  response.write("404 Not Found\n");
  response.end();

You can change to

  response.writeHead(404, {"Content-Type": "text/html"});
  response.write(HTMLDATA);
  response.end();

'HTMLDATA' being either a string of HTML or a reference to a file you have gathered.

response.writeHead() is always set before the response.write().

Also see we have set the response type to 'text/html'
