The individual parts are separately validated only if the resulting complete spec is invalid. Note: the OpenAPI plugin validates the spec given to it, so normally no manual validation is necessary. > >Test plan: >1. prove -v t/db_dependent/Koha/REST/* >2. prove -v t/db_dependent/api/v1/* > >Sponsored-by: The National Library of Finland >--- > Koha/REST/Plugin/PluginRoutes.pm | 2 + > Koha/REST/V1.pm | 82 ++++++++++++++++++++++---------- > 2 files changed, 60 insertions(+), 24 deletions(-) > >diff --git a/Koha/REST/Plugin/PluginRoutes.pm b/Koha/REST/Plugin/PluginRoutes.pm >index 273d5df708..e993b563d0 100644 >--- a/Koha/REST/Plugin/PluginRoutes.pm >+++ b/Koha/REST/Plugin/PluginRoutes.pm >@@ -70,6 +70,8 @@ sub register { > sub inject_routes { > my ( $spec, $plugin, $validator ) = @_; > >+ return merge_spec( $spec, $plugin ) unless $validator; >+ > return try { > > my $backup_spec = merge_spec( clone($spec), $plugin ); >diff --git a/Koha/REST/V1.pm b/Koha/REST/V1.pm >index b1f4657d4a..63cfefe111 100644 >--- a/Koha/REST/V1.pm >+++ b/Koha/REST/V1.pm >@@ -21,6 +21,7 @@ use Mojo::Base 'Mojolicious'; > > use C4::Context; > use JSON::Validator::OpenAPI::Mojolicious; >+use Try::Tiny; > > =head1 NAME > >@@ -58,33 +59,66 @@ sub startup { > } > > my $validator = JSON::Validator::OpenAPI::Mojolicious->new; >- $validator->load_and_validate_schema( >- $self->home->rel_file("api/v1/swagger/swagger.json"), >- { >- allow_invalid_ref => 1, >- } >- ); > > push @{$self->routes->namespaces}, 'Koha::Plugin'; > >- my $spec = $validator->schema->data; >- $self->plugin( >- 'Koha::REST::Plugin::PluginRoutes' => { >- spec => $spec, >- validator => $validator >- } >- ); >- >- $self->plugin( >- OpenAPI => { >- spec => $spec, >- route => $self->routes->under('/api/v1')->to('Auth#under'), >- allow_invalid_ref => >- 1, # required by our spec because $ref directly under >- # Paths-, Parameters-, Definitions- & Info-object >- # is not allowed by the OpenAPI specification. >- } >- ); >+ # Try to load and merge all schemas first and validate the result just once. >+ my $spec; >+ try { >+ $spec = $validator->bundle( >+ { >+ replace => 1, >+ schema => $self->home->rel_file("api/v1/swagger/swagger.json") >+ } >+ ); >+ >+ $self->plugin( >+ 'Koha::REST::Plugin::PluginRoutes' => { >+ spec => $spec, >+ validator => undef >+ } >+ ); >+ >+ $self->plugin( >+ OpenAPI => { >+ spec => $spec, >+ route => $self->routes->under('/api/v1')->to('Auth#under'), >+ allow_invalid_ref => >+ 1, # required by our spec because $ref directly under >+ # Paths-, Parameters-, Definitions- & Info-object >+ # is not allowed by the OpenAPI specification. >+ } >+ ); >+ } >+ catch { >+ # Validation of the complete spec failed.
