Javascript Node.js服务器"；“404未找到”；发送至404.html页面的消息

我正在使用node.js，我想知道如何显示404.html而不是“404未找到”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\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");

正如您所看到的，它只是一个静态文件服务器，我没有使用express.js或任何东西。

只需使用fs.readFile加载404.html，并使用response.write为其提供服务

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) {
  fs.readFile('404.html', "binary", function(err, file) {
    if(err) {
       response.writeHead(404, {"Content-Type": "text/html"});
       response.write("404 Not Found\n");
    } else {
       response.writeHead(404);
       response.write(file, "binary");            
    }
    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");`enter code here`

只为200美元而做。。。 读取文件404.html并将其写入响应，只需将代码404设置为writeHead

response.writeHead(404, {
  'Location': 'your/404/path.html'
  //add other headers here...
});
response.end();

还是用一行

response.redirect('your/404/path.html');

在您的404案例中

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

你可以换成

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

“HTMLDATA”是HTML字符串或对已收集文件的引用

response.writeHead（）

总是在

response.write（）之前设置

另请参见我们已将响应类型设置为“text/html”


这可能是您需要的更多内容

    fs.readFile('404.html', function(error, data) {
        res.writeHead(404, {'content-type': 'text/html'});
        res.end(data);
    });

这是对的！非重定向，状态为404，内容类型为text/html
