转发HTTP使用EBS和放大器在Node.js的EX preSS应用程序的https; ELB环境 [英] Forwarding http to https in node.js express app using EBS & ELB environment
问题描述
我使用下面的重定向所有的HTTP请求到HTTPS请求。
I am using the following to redirect all http requests to https requests.
我可以从日志的标题的X转发,原是从来没有填充,是不确定的。请参阅
I can see from logs that the header 'x-forwarded-proto' is never populated and is undefined.
app.get('*', function(req, res, next) {
//http://docs.aws.amazon.com/ElasticLoadBalancing/latest/DeveloperGuide/TerminologyandKeyConcepts.html#x-forwarded-proto
if (req.headers['x-forwarded-proto'] != "https") {
res.redirect('https://' + req.get('host') + req.url);
} else {
next();
}
});
这是导致重定向循环。要如何把不正常的循环?
It is causing a redirect loop. How can I redirect properly without looping?
推荐答案
编辑:
我下面原来的答复是 EX preSS 3.X ,为4.x版,你可以得到一个字符串 HTTP
或 HTTPS
在 REQ。协议
,THX @BrandonClark
edit:
my original answer below is for express 3.x, for 4.x you can get a string http
or https
in req.protocol
, thx @BrandonClark
使用 req.get
,不是 req.headers
。需要注意的是POST请求和所有其他非GET不会看到这个中间件。
这也有可能是前preSS不携带当你重定向跨的X转发,原
头。你可能需要自己设置它。
use req.get
, not req.headers
. Note that POST requests and all other non-GET will not see this middleware.
It's also possible that Express does not carry the x-forwarded-proto
header across when you redirect. You may need to set it yourself.
app.get('*', function(req, res, next) {
//http://docs.aws.amazon.com/ElasticLoadBalancing/latest/DeveloperGuide/TerminologyandKeyConcepts.html#x-forwarded-proto
if (req.get('x-forwarded-proto') != "https") {
res.set('x-forwarded-proto', 'https');
res.redirect('https://' + req.get('host') + req.url);
} else {
next();
}
});
另一种方式来强制HTTPS:
Another way to force https:
function ensureSecure(req, res, next){
if(req.secure){
// OK, continue
return next();
};
res.redirect('https://'+req.host+req.url); // handle port numbers if non 443
};
app.all('*', ensureSecure);
