Rails forms leading to Mixed Content warning - ruby-on-rails

In my Rails app I use both Rails' native form_tag method and the simple_form_for method provided by the simple_form rubygem.
Both of them are leading to the following warning in the chrome console:
Mixed Content: The page at 'https://example.com' was loaded over a secure connection, but contains a form which targets an insecure endpoint 'http://example.com'. This endpoint should be made available over a secure connection.
And indeed, the rendered HTML forms use the http protocol for their action attribute.
What is the reason for that? All my other URL's use the https protocol.

You have not correct protocol set up for your environment.
Your server is running on HTTPS and form creates HTTP URL.
You need to tell your URL helpers to build the URLs with the same protocol as your server is running for your environment.
Development should run on HTTP, staging should be HTTPS and production as well HTTPS.
There are different ways how to do it. The best is to set protocol in your environment config file. So place this line:
Rails.application.routes.default_url_options[:protocol] = 'https'
into your environment config file like production.rb and staging.rb.
Another approach is to set the default protocol per controller action. Check this one for more info.
In case you are using the mailer, also check your mailer protocol settings. As described here.

issue with debug server proxy config

Using the angular 2 debug server, I proxy requests to the real server using proxy.config.js. It seems that the ng2-signalr library does not respect the proxy configuration, and will attempt requests to whatever was defined as url in the IConnectionOptions used.
for the following request:
GET
localhost:4200/signalr/negotiate?clientProtocol=2.1&user=client&connectionData=%5B%7B%22name%22%3A%22compilationhub%22%7D%5D&_=1557816148076
the following error is produced:
Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, https
What would be the best course of action?
I got this working by adding the signalr route to proxy.config.js and setting the url property of my IConnectionOptions to location.origin. This setup bypasses the default route of /signalr so that a double forward slash route is not used.

How to disable SSL for custom subdomain

I've got a non wildcard SSL certificate for my root domain (example.com), and I'm using the heroku ssl endpoint add on. I'm using routing constraints so subdomain.example.com matches various controller actions, and I reroute the subdomain with CNAME records to the root domain. This all works fine in development, and it works fine in Tor browser if I disable https, but I can't get it to work in any ordinary browser.
I've tried using gem SSL-enforcer to enforce SSL except on host with subdomain as such:
config.middleware.use Rack::SslEnforcer, :except_hosts => 'subdomain.mydomain.com', :strict => true
Can I disable the https protocol for subdomain of my rails app? I feel like this might be impossible as I've read that SSL negotiations are made before the server knows the URL.
I would have recommended SSL-enforcer.....
Are you using config.force_ssl and generating a strict transport security header? I would suspect that might be the issue if it works with Tor but not a normal browser. Check the headers; if the HSTS exists, then that's probably the reason. Should be straight forward to change that (changing the max-age attribute to 0)
If not, check the Heroku docs again and make sure your settings and DNS/CNAME are correct....

Hope this helps.

Grails redirect with reverse proxy

We've developed a Grails application that uses redirects.
Beacuse of external reasons, we are just recently using reverse-proxy, to split some traffic to domains:
From:
demo1.company.local (the server itself)
To:
tomcat.company.local (for all java applications, including our grails app)
lotus.company.local (for all Domino applications)
Since tomcat is only configured in the hosts file on the demo1 server, the redirects do not work when I access the application from anywhere else then the demo1 server itself.
I've tried to solve this using "absolute" and/or "base" parameter in Grails' redirect(), but if I understand correctly, this is Grails 2+ only and we're using Grails 1.3.4.
Are there other ways to redirect to a specified host?
Am I misusing things?
Thanks,
Bram
If you define grails.serverURL in Config.groovy, redirects with absolute:true will use that value for the URL.

Rails: activating SSL support gets Chrome confused

There is a nice option to config for the Rails app:
config.force_ssl = true
However it seems that just putting that to true doesn't get the HTTPS connections working. Even more - after trying (and failing) to connect to https://localhost:3000 with Chrome, I've set this option to false, and Chrome still tries to open https, even if I write http.
So, couple of questions:
--How to force Chrome not to try https anymore?
--What is the proper way of enabling SSL on my Rails app?
Update: The app is run on Heroku, and it seems that https is supported there automagically. Can I test SSL also locally? Like when running rails server?
First, I should say that I haven't tried this, but there are mainly two possibly reasons for Chrome still using HTTPS:
Using HTTP Strict Transport Security headers: if the server sets them, the client (supporting HSTS, like Chrome) is meant to stick to HTTPS for all subsequent requests to that host.
Permanent redirects. If the initial redirect you got was using "301 Moved Permanently" (and not 302 for example) to make the redirection,(*) the browser is meant to remember it ("The requested resource has been assigned a new permanent URI and any future references to this resource SHOULD use one of the returned URIs").
A likely solution to this would be to clear the cache in your browser.
(*) This question seems to indicate this is the case for Ruby on Rails with this config).
I had the same issue. What I did is using an ssl enforcer gem which adds a middleware that handles ssl and redirects. It has a strict option which enforces the configured protocols.
in your Gemfile add:
gem 'rack-ssl-enforcer'
in production.rb add:
config.middleware.use Rack::SslEnforcer, only: %r{your_regex_condition}, strict: true
This will force the requested pages to be secured and the rest to be non secured. It disables the HSTS header which is problematic in chrome (redirect caching issue).
You can also expire the cache for all cleints (if it already exist) to make sure you'll not get infinite redirect:
config.middleware.use Rack::SslEnforcer, only: %r{your_regex_condition}, :hsts => { :expires => 1, :subdomains => false }
also remove the ssl enforcement in production.rb (otherwise it might conflict with this middleware):
config.force_ssl = false
Let's see what happened once you updated your config file with:
config.force_ssl = true
This has caused Rack SSL Middleware to be loaded as the first middleware. As you can see in the code, Rack SSL sets an HSTS header by adding this line to the headers :
Strict-Transport-Security
It tells supported browsers such as Chrome to use HTTPS only to access your website.
So once you set back :
config.force_ssl = false
Chrome will still uses HTTPS to access your website and causes an error.
To solve this problem, you need to empty the HSTS cache. You can to that by going to the following url in your chrome browser :
chrome://net-internals/#hsts
Open your Chrome Developer Tools when you're at localhost: Then you can right click the refresh button ↻ and select "Empty cache and hard reload".
This error might also happens to you, if you start your server in the production environment, where HSTS is enabled.
Chrome redirects you to https://localhost:3000/ and says "SSL connection error".

Rails request object contains wrong protocol

I'm running Rails 3.1.2 on Apache with the latest Passenger, 3.0.11. I'm using force_ssl to require a secure connection in a few of my application's actions.
The web browser is warning that although the identity of the site has been verified and the connection is encrypted, the page contains other resources which are not secure. The culprit is a reference to the Google Fonts API being made over plain http. My view contains the following:
= stylesheet_link_tag "#{request.port}fonts.googleapis.com/css?family=Oswald"
I also tried this:
= stylesheet_link_tag "http#{request.ssl? ? 's' : ''}://fonts.googleapis.com/css?family=Oswald"
Both of these result in the stylesheet url having "http://".
I had success doing this in a Rails 3.0.5/Passenger 3.0.7/SslRequirement, but can't get it to work in Rails 3.2.1/Passenger 3.0.11/force_ssl.
put "//fonts.googleapis.com/css?family=Oswald" without the http or https - that way the browser uses the same protocol as the page you are on and doesn't show any warnings.
