Récemment, nous avons migré notre projet de .NET Core 2.0
à .NET Core 2.1
. En conséquence, notre site de documentation Swagger a cessé de fonctionner. Nous sommes toujours en mesure d'y accéder. Nous pouvons voir le titre et la version personnalisés, mais il n'y a pas de documentation sur l'API, mais juste un message disant No operations defined in spec!
.
J'ai essayé une solution plus ancienne pour .NET Core 2.0 , mais cela n’a pas aidé. Sur la base des deux articles suivants 12 / J'ai essayé de supprimer les attributs Swagger des méthodes de contrôleur et d'ajouter un attribut [ApiController]
au-dessus de la classe de contrôleur, mais cela n'a pas aidé. Quelqu'un peut-il aider à résoudre ce problème?

J'ai essayé de recréer la même solution ligne par ligne. Swagger a travaillé jusqu'à ce que j'ai ajouté <PreserveCompilationContext>false</PreserveCompilationContext>
dans le fichier .csproj
. La suppression de cet attribut a provoqué la réapparition de l'interface utilisateur Swagger.
Pour moi, cette erreur est apparue pourquoi j'ai essayé d'utiliser l'attribut [ApiVersionNeutral] sur le contrôleur v1 et [ApiVersion ("2.0")] sur le contrôleur v2. Quoi qu'il en soit, vous pouvez obtenir un message d'erreur complet dans les outils de sortie ou de diagnostic (onglet Evénements). Et alors j'ai eu ce message:
System.NotSupportedException: Méthode HTTP "GET" & chemin "api/Employees" surchargé par des actions - Api.V2.Controllers.EmployeesController.Get , Api.V1.Controllers.EmployeesController.Get.
Les actions nécessitent une combinaison unique méthode/chemin pour Swagger 2.0. Utilisation ConflictingActionsResolver en guise d'une solution de contournement
