假设我的示例URL是
http://example.com/one/two
我说我有以下路线
app.get('/one/two', function (req, res) {
var url = req.url;
}
url的值是/one/two。
如何在Express中获得完整的URL ? 例如,在上面的情况下,我想收到http://example.com/one/two。

我的代码是这样的,
params['host_url'] = req.protocol + '://' + req.headers.host + req.url;
其他回答
使req.host /点播。当Express后台代理时,主机名有效必须满足两个条件:
App.set('信任代理','环回');在app.js x - forward - host头必须由你自己在webserver中指定。如。apache, nginx
nginx:
server {
listen myhost:80;
server_name myhost;
location / {
root /path/to/myapp/public;
proxy_set_header X-Forwarded-Host $host:$server_port;
proxy_set_header X-Forwarded-Server $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass http://myapp:8080;
}
}
apache:
<VirtualHost myhost:80>
ServerName myhost
DocumentRoot /path/to/myapp/public
ProxyPass / http://myapp:8080/
ProxyPassReverse / http://myapp:8080/
</VirtualHost>
你可以像这样在路由中使用这个函数
app.get('/one/two', function (req, res) {
const url = getFullUrl(req);
}
/**
* Gets the self full URL from the request
*
* @param {object} req Request
* @returns {string} URL
*/
const getFullUrl = (req) => `${req.protocol}://${req.headers.host}${req.originalUrl}`;
要求的事情。Protocol会给出HTTP或https, Req.headers.host会给你完整的主机名,比如www.google.com, 要求的事情。originalUrl会给出剩下的路径名(在你的例子中是/one/two)
通常我依赖这2个,取决于服务器和代理是否存在:
req.socket.remoteAddress
req.headers.referer
async function (request, response, next) {
const url = request.rawHeaders[9] + request.originalUrl;
//or
const url = request.headers.host + request.originalUrl;
}
你可以从req of express得到完整的url。
function fetchPages(req, res, next) {
let fullUrl = req.headers.host + req.originalUrl;
console.log("full url ==> ",fullUrl);
}
