问题描述
我想让我的API控制器使用SSL,所以我在我的nginx.conf中添加了另一个监听指令
upstream unicorn {
server unix:/tmp/unicorn.foo.sock fail_timeout=0;
}
server {
listen 80 default deferred;
listen 443 ssl default;
ssl_certificate /etc/ssl/certs/foo.crt;
ssl_certificate_key /etc/ssl/private/foo.key;
server_name foo;
root /var/apps/foo/current/public;
try_files $uri/system/maintenance.html $uri/index.html $uri @unicorn;
location @unicorn {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off;
proxy_pass http://unicorn;
}
error_page 502 503 /maintenance.html;
error_page 500 504 /500.html;
keepalive_timeout 5;
}
顺利通过nginx竞赛.我还向我的ApiController添加了force_ssl
指令
class ApiController < ApplicationController
force_ssl if Rails.env.production?
def auth
user = User.authenticate(params[:username], params[:password])
respond_to do |format|
format.json do
if user
user.generate_api_key! unless user.api_key.present?
render json: { key: user.api_key }
else
render json: { error: 401 }, status: 401
end
end
end
end
def check
user = User.find_by_api_key(params[:api_key])
respond_to do |format|
format.json do
if user
render json: { status: 'ok' }
else
render json: { status: 'failure' }, status: 401
end
end
end
end
end
当我不使用SSL时,它工作得很好,但是现在当我尝试使用curl --LI http://foo/api/auth.json
时,可以正确地重定向到https
,但是随后我继续重定向到http://foo/api/auth
,以无限重定向结束循环.
我的路线只是
get "api/auth"
get "api/check"
我正在Ruby 1.9.2和Nginx 0.7.65上使用Rails 3.2.1
您没有转发有关此请求是否为HTTPS终止请求的任何信息.通常,在服务器中,"ssl on";指令将设置这些标头,但您使用的是组合块.
机架(和force_ssl)通过以下方式确定SSL:
- 如果请求是通过端口443传入的(这很可能不会从nginx传递回Unicorn)
- 如果ENV ['HTTPS'] =="on"
- 如果X-Forwarded-Proto标头=="HTTPS"
有关完整故事,请参见 force_ssl来源. /p>
由于您正在使用组合块,因此您想使用第三种形式.试试:
proxy_set_header X-Forwarded-Proto $scheme;
在服务器或位置阻止中根据nginx文档.
当您进入端口80请求时,会将标头设置为"http",而当您进入443请求时,将标头设置为"https".
I want to have my API controller use SSL, so I added another listen directive to my nginx.conf
upstream unicorn {
server unix:/tmp/unicorn.foo.sock fail_timeout=0;
}
server {
listen 80 default deferred;
listen 443 ssl default;
ssl_certificate /etc/ssl/certs/foo.crt;
ssl_certificate_key /etc/ssl/private/foo.key;
server_name foo;
root /var/apps/foo/current/public;
try_files $uri/system/maintenance.html $uri/index.html $uri @unicorn;
location @unicorn {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off;
proxy_pass http://unicorn;
}
error_page 502 503 /maintenance.html;
error_page 500 504 /500.html;
keepalive_timeout 5;
}
which passes the nginx conftest without any problems. I also added a force_ssl
directive to my ApiController
class ApiController < ApplicationController
force_ssl if Rails.env.production?
def auth
user = User.authenticate(params[:username], params[:password])
respond_to do |format|
format.json do
if user
user.generate_api_key! unless user.api_key.present?
render json: { key: user.api_key }
else
render json: { error: 401 }, status: 401
end
end
end
end
def check
user = User.find_by_api_key(params[:api_key])
respond_to do |format|
format.json do
if user
render json: { status: 'ok' }
else
render json: { status: 'failure' }, status: 401
end
end
end
end
end
which worked just fine when I wasn't using SSL, but now when I try to curl --LI http://foo/api/auth.json
, I get properly redirected to https
, but then I keep on getting redirected to http://foo/api/auth
ending in an infinite redirect loop.
My routes simply have
get "api/auth"
get "api/check"
I'm using Rails 3.2.1 on Ruby 1.9.2 with nginx 0.7.65
You're not forwarding any information about whether this request was an HTTPS-terminated request or not. Normally, in a server, the "ssl on;" directive will set these headers, but you're using a combined block.
Rack (and force_ssl) determines SSL by:
- If the request came in on port 443 (this is likely not being passed back to Unicorn from nginx)
- If ENV['HTTPS'] == "on"
- If the X-Forwarded-Proto header == "HTTPS"
See the force_ssl source for the full story.
Since you're using a combined block, you want to use the third form. Try:
proxy_set_header X-Forwarded-Proto $scheme;
in your server or location block per the nginx documentation.
This will set the header to "http" when you come in on a port 80 request, and set it to "https" when you come in on a 443 request.
