Nodejs:重定向 URL

问题描述：

我正在尝试以这种方式在 node.js 中重定向我的应用程序的 URL:

I'm trying to redirect the url of my app in node.js in this way:

// response comes from the http server
response.statusCode = 302;
response.setHeader("Location", "/page");
response.end();

但是当前页面和新页面混在一起，看起来很奇怪:|我的解决方案看起来完全合乎逻辑，我真的不知道为什么会发生这种情况，但是如果我在重定向后重新加载页面，它会起作用.

But the current page is mixed with the new one, it looks strange :| My solution looked totally logical, I don't really know why this happens, but if I reload the page after the redirection it works.

无论如何，在节点中进行 HTTP 重定向的正确方法是什么?

Anyway what's the proper way to do HTTP redirects in node?

答

看起来 express 和你的方式差不多.从我所看到的不同之处在于它们推送一些正文内容并使用绝对网址.

Looks like express does it pretty much the way you have. From what I can see the differences are that they push some body content and use an absolute url.

查看 express response.redirect 方法:

See the express response.redirect method:

https://github.com/visionmedia/express/blob/master/lib/response.js#L335

// Support text/{plain,html} by default
  if (req.accepts('html')) {
    body = '<p>' + http.STATUS_CODES[status] + '. Redirecting to <a href="' + url + '">' + url + '</a></p>';
    this.header('Content-Type', 'text/html');
  } else {
    body = http.STATUS_CODES[status] + '. Redirecting to ' + url;
    this.header('Content-Type', 'text/plain');
  }

  // Respond
  this.statusCode = status;
  this.header('Location', url);
  this.end(body);
};
