Original Pull Request: https://github.com/bitwarden/android/pull/2579

State: closed
Merged: Yes

Type of change

  • Bug fix
  • New feature development
  • Tech debt (refactoring, code cleanup, dependency upgrades, etc)
  • Build/deploy pipeline (DevOps)
  • Other

Objective

Refactor forwarded email providers to use better patterns, reuse code and improve maintainability.

Code changes

  • GeneratorPage.xaml: Refactor all forwarded email providers to unify all the API token/key into one field binded which changes its value depending on the provider type selected. This makes the view tree lighter and changing from one type to the other smoother.
  • GeneratorPageViewModel.cs: Unified all the API Token/Key into ForwardedEmailApiSecret alongside the label and the show toggle as well. Inside it gets/sets the correct one depending on the type selected. Simplified the api secret toggle command and improved the errors to the user when we get a 401/403 from the provider.
  • ForwardedEmailInvalidSecretException.cs: Special exception to be raised when a 401/403 is gotten from the provider.
  • UsernameGenerationOptions.cs: Added the "mapper" of the particular options for the forwarded email services.
  • UsernameGeneratorConfig.cs: No longer necessary -> Removed.
  • ApiService.cs: Moved all the particular forwarded email logic to the new ...Forwarder classes and added a new SendAsync(HttpRequestMessage, CancellationToken) to be used for these kind of things where we don't call our API. Only left GetFastmailAccountIdAsync(...) cause I didn't want to move the HttpClient outside this class in this PR. ♻️ Eventually, we should refactor this class and split it, it's getting pretty big.
  • CryptoService.cs: Moved RandomStringAsync here cause it made more sense to be in the same place as random number.
  • BaseForwarder.cs: Base class for all forwarders where it makes the call to the service with custom configurations from its children.
  • AnonAddyForwarder.cs, DuckDuckGoForwarder.cs, FastmailForwarder.cs, FirefoxRelayForwarder.cs, SimpleLoginForwarder.cs: Forwarder providers particular logic and configurations.
  • ForwarderOptions.cs: Options to configure the forwarders.
  • UsernameGenerationService.cs: Refactor the forwarder email to create the appropriate forwarder and generate accordingly.
