hi
Please share full code of your
CatOsHttpApiClientTestModuleIt needs to depends on
AbpHttpClientModule -

Full class , and I am already depending on the mentioned module :
[DependsOn( typeof(AbpAutofacModule), typeof(AbpHttpClientModule), //used to create client proxies typeof(CatOsApplicationContractsModule), //used to create client proxies, typeof(AbpAspNetCoreModule), typeof(CatOsHttpApiClientModule) )] public class CatOsHttpApiClientTestModule : AbpModule { private readonly string RemoteServiceName = "Default"; public override void ConfigureServices(ServiceConfigurationContext context) { context.Services.AddHttpClientProxies( typeof(CatOsApplicationContractsModule).Assembly, RemoteServiceName ); context.Services.AddAutofac(); context.Services.AddControllers(); context.Services.AddEndpointsApiExplorer(); context.Services.AddHttpContextAccessor(); context.Services.AddScoped<ScenarioManager>(); context.Services.AddSwaggerGen(options => { options.AddSecurityDefinition( "Bearer", new Microsoft.OpenApi.Models.OpenApiSecurityScheme { Name = "Authorization", Type = Microsoft.OpenApi.Models.SecuritySchemeType.Http, Scheme = "Bearer", BearerFormat = "JWT", In = Microsoft.OpenApi.Models.ParameterLocation.Header, Description = "Enter 'Bearer' [space] and then your token in the text input below.\n\nExample: 'Bearer 12345abcdef'", } ); options.AddSecurityRequirement( new Microsoft.OpenApi.Models.OpenApiSecurityRequirement { { new Microsoft.OpenApi.Models.OpenApiSecurityScheme { Reference = new Microsoft.OpenApi.Models.OpenApiReference { Type = Microsoft.OpenApi.Models.ReferenceType.SecurityScheme, Id = "Bearer", }, }, new string[] { } }, } ); }); context.Services.AddHttpClient( "catos", (sp, client) => { var scenarioManager = sp.GetRequiredService<ScenarioManager>(); var configuration = sp.GetRequiredService<IConfiguration>(); client.BaseAddress = new Uri( configuration.GetValue<string>("RemoteServices:Default:BaseUrl") ); var jwtToken = scenarioManager.GetOrCreate().StringData[ ScenarioContext.AccessToken ]; client.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Bearer", jwtToken); } ); } public override void OnApplicationInitialization(ApplicationInitializationContext context) { var app = context.GetApplicationBuilder(); var env = context.GetEnvironment(); // Configure the HTTP request pipeline. if (env.IsDevelopment()) { app.UseSwagger(); app.UseSwaggerUI(); } app.UseHttpsRedirection(); // app.UseAuthorization(); app.UseRouting(); // Added to enable endpoint routing app.UseEndpoints(endpoints => // Updated to use IEndpointRouteBuilder { endpoints.MapControllers(); }); } } -
