これで私を助けてください、それは最初は簡単に見えました、今私はプロジェクトに遅れています:
ASP.NET WebApiプロジェクトのAPIバージョン管理をSwaggerとともにセットアップしようとしています。 APIのバージョン管理は適切に機能し、異なるバージョンを呼び出すと正しい結果が返されます(以下を参照)。
逆に、Swaggerは両方のバージョンを提供できません。デバッグ中に、SwaggerConfig.csでc.MultipleApiVersions(...)
が呼び出されると、コントローラーがapiDesc.ActionDescriptor.ControllerDescriptor
は常にPingController
であり、決してPing11Controller
。
誰かがこれを解決するために何をする必要があるかを指摘し、Swaggerを両方のバージョンで機能させることはできますか?
以下では、Swaggerがv1.0でのみ機能するのに対して、APIバージョン管理のコードと証明が正常に機能します。
ありがとうございました!
Swagger for v1.0は優れています:( http:// localhost:50884/v1.0/swagger )
{
"swagger":"2.0",
"info":{
"version":"v1.0",
"title":"My API v1.0"
},
"Host":"localhost:50884",
"schemes":[
"http"
],
"paths":{
"/api/ping":{
"get":{
"tags":[
"Ping"
],
"summary":"Get a pong.",
"operationId":"GetAPong",
"consumes":[
],
"produces":[
"application/json",
"text/json",
"application/xml",
"text/xml"
],
"responses":{
"200":{
"description":"OK"
},
"404":{
"description":"NotFound"
}
}
}
}
},
"definitions":{
}
}
v1.1のSwaggerが空です:( http:// localhost:50884/v1.1/swagger )
{
"swagger":"2.0",
"info":{
"version":"v1.1",
"title":"My API v1.1"
},

それを解決する:
以下のようにバージョン管理されたAPI Explorerを使用します(初期化の問題のため、WebApiConfig.csのSwaggerConfig.csからコードを移動する必要がありました)。
var apiExplorer = config.AddVersionedApiExplorer(options => {
options.GroupNameFormat = "'v'VVV";
});
var versionSupportResolver = new Func<ApiDescription, string, bool>((apiDescription, version) => apiDescription.GetGroupName() == version);
var versionInfoBuilder = new Action<VersionInfoBuilder>(info => {
foreach (var group in apiExplorer.ApiDescriptions)
{
info.Version(group.Name, $"MyAPI v{group.ApiVersion}");
}
});
config
.EnableSwagger("{apiVersion}/swagger", swagger => {
swagger.OperationFilter<SwaggerDefaultValues>();
swagger.MultipleApiVersions(versionSupportResolver, versionInfoBuilder);
swagger.IncludeXmlComments(WebApiConfig.XmlCommentsFilePath);
})
.EnableSwaggerUi(swaggerUi => {
swaggerUi.EnableDiscoveryUrlSelector();
swaggerUi.DocExpansion(DocExpansion.List);
});
