mod_http_oauth2: Always show early errors to user
Before having validated the client_id, communicating an error back to
the client via redirect would make this an open redirect, so we may just
as well skip past that logic, and especially the warning log message.

--- labels: - Stage-Alpha summary: "Authenticate users against an external HTTP API" ... # Overview This authentication module allows Prosody to authenticate users against an external HTTP service. # Configuration ``` lua VirtualHost "example.com" authentication = "http" http_auth_url = "http://example.com/auth" ``` If the API requires Prosody to authenticate, you can provide static credentials using HTTP Basic authentication, like so: ``` http_auth_credentials = "prosody:secret-password" ``` # Developers This section contains information for developers who wish to implement a HTTP service that Prosody can use for authentication. ## Protocol Prosody will make a HTTP request to the configured API URL with an appended `/METHOD` where `METHOD` is one of the methods described below. GET methods must expect a series of URL-encoded query parameters, while POST requests will receive an URL-encoded form (i.e. `application/x-www-form-urlencoded`). ## Parameters user : The username, e.g. `stephanie` for the JID `stephanie@example.com`. server : The host part of the user's JID, e.g. `example.com` for the JID `stephanie@example.com`. pass : For methods that verify or set a user's password, the password will be supplied in this parameter, otherwise it is not set. ## Methods The only mandatory methods that the service must implement are `check_password` and `user_exists`. Unsupported methods should return a HTTP status code of `501 Not Implemented`, but other error codes will also be handled by Prosody. Method HTTP method Success codes Error codes Response -------- ---- --- ----------------- ----------------------------------------------------------------- register POST 201 409 (user exists) check\_password GET 200 A text string of `true` if the user exists, or `false` otherwise. user\_exists GET 200 A text string of `true` if the user exists, or `false` otherwise. set\_password POST 200, 201 or 204 remove\_user POST 200, 201 or 204 ## Examples With the following configuration: ``` authentication = "http" http_auth_url = "https://auth.example.net/api" If a user connects and tries to log in to Prosody as "romeo@example.net" with the password "iheartjuliet", Prosody would make the following HTTP request: ``` https://auth.example.net/api/check_password?user=romeo&server=example.net&pass=iheartjuliet ``` # Compatibility Requires Prosody 0.11.0 or later.
