本文介绍了如何将用户的浏览器URL重定向到Nodejs中的其他页面?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
在我正在尝试编写的应用程序中,主页面( http:// localhost:8675 )具有以下表格:
In the application I'm trying to write, the main page (http://localhost:8675) has the following form:
<form action='/?joinnew' method='post'>
<button>Start</button>
</form>
这是server.js中的代码:
Here is the code in server.js:
http.createServer(function(request, response) {
var root = url.parse(request.url).pathname.split('/')[1];
if (root == '') {
var query = url.parse(request.url).search:
if (query == '?joinnew') {
var newRoom = getAvaliableRoomId(); // '8dn1u', 'idjh1', '8jm84', etc.
// redirect the user's web browser to a new url
// ??? How to do. Need to redirect to 'http://whateverhostthiswillbe:8675/'+newRoom
...
}}}
我很乐意,如果有办法,我不需要知道主机地址,因为这可能会改变。
I would love if there were a way to do it where I didn't have to know the host address, since that could be changing.
'http'对象是常规需求('http'),不需要('express')。
The 'http' object is a regular require('http'), NOT require('express').
推荐答案
response.writeHead(301,
{Location: 'http://whateverhostthiswillbe:8675/'+newRoom}
);
response.end();
