Can't hit the endpoint #203

stevesuh · 2021-10-27T17:45:44Z

Been stumped since yesterday afternoon and paired with another engineer today but still stuck. Any pointers would be appreciated.

Switched to an endpoint that doesn't need auth just to try to get it working.

Figured out the issue. Need to set HTTP_HOST to localhost.

https://stackoverflow.com/questions/65433303/sending-a-rack-request-through-rails-console

Might be helpful to update the README for next chap.

schneems · 2021-10-28T17:15:07Z

I think the problem here is that PATH_TO_HIT is only supposed to be a path, not a full host.

Does it work if you use PATH_TO_HIT=/v1/users/reservation_history without HTTP_HOST ?

We could detect the case of that starting with http or localhost:<port> and issue a warning. I would be open to a PR adding that check.

stevesuh · 2021-10-28T17:29:41Z

It tries to go to example.org if you remove HTTP_HOST=localhost

Also the README says you can use a full uri.

schneems · 2021-10-29T00:22:21Z

You are right there about passing in fully qualified hosts. Thankfully past me documented it :)

It looks like some logic somewhere in your app is blocking connections.

where is this output coming from “Blocked host”?

Can you reproduce this with a “rails new” app?

Michoels · 2024-01-28T14:38:40Z

I just had this as well.
Without HTTP_HOST=localhost, I got this error:

 <!-- BEGIN <REDACTED>/gems/ruby-3.2.2/gems/actionpack-7.0.8/lib/action_dispatch/middleware/templates/rescues/blocked_host.html.erb -->
 <header>
  <h1>Blocked hosts: </h1>

<main role="main" id="container">
  <h2>To allow requests to these hosts, make sure they are valid hostnames (containing only numbers, letters, dashes and dots), then add the following to your environment configuration:</h2>
  <pre>
    config.hosts &lt;&lt; ""
  </pre>
  <p>For more details view: <a href="https://guides.rubyonrails.org/configuring.html#actiondispatch-hostauthorization">the Host Authorization guide</a></p>

When I added HTTP_HOST=localhost the error disappeared.
This behavior is documented in the Rails docs here.

The command that worked was:

HTTP_HOST=localhost RAILS_ENV=development PATH_TO_HIT=/sync/3/start USE_AUTH=true bundle exec derailed exec perf:mem
