【问题描述】：

我正在使用 Azure 函数 V3 这是我的启动.cs 公共覆盖无效配置（IFunctionsHostBuilder 构建器） var configuration = builder.GetContext().Configuration;

        builder.AddSwashBuckle(Assembly.GetExecutingAssembly(), opts =>
        
            opts.SpecVersion = Microsoft.OpenApi.OpenApiSpecVersion.OpenApi3_0;
            opts.Title = "My test app";
            
            opts.ConfigureSwaggerGen = x =>
            
                //custom operation example
                x.CustomOperationIds(apiDesc => apiDesc.TryGetMethodInfo(out MethodInfo methodInfo)
                ? methodInfo.Name
                : new Guid().ToString());

                //custom filter example
                //x.DocumentFilter<RemoveSchemasFilter>();
                //oauth2
                x.AddSecurityDefinition("oauth2", new OpenApiSecurityScheme
                
                    Type = SecuritySchemeType.OAuth2,
                    Flows = new OpenApiOAuthFlows
                    
                        Implicit = new OpenApiOAuthFlow
                        
                            AuthorizationUrl = new Uri(string.Format("https://login.microsoftonline.com/0/oauth2/v2.0/authorize", configuration["AzureAd:TenantId"])),
                            Scopes = new Dictionary<string, string>
                            
                                 configuration["AzureAd:scope"], "scope" 
                            
                        ,
                        AuthorizationCode = new OpenApiOAuthFlow
                        
                            AuthorizationUrl = new Uri(string.Format("https://login.microsoftonline.com/0/oauth2/v2.0/authorize", configuration["AzureAd:TenantId"])),
                            TokenUrl = new Uri(string.Format("https://login.microsoftonline.com/0/oauth2/v2.0/token", configuration["AzureAd:TenantId"])),
                            Scopes = new Dictionary<string, string>
                            
                                 configuration["AzureAd:scope"], "scope" 
                            

                        
                    
                );
                x.AddSecurityRequirement(new OpenApiSecurityRequirement
                
                     
                     new OpenApiSecurityScheme
                        
                        Reference = new OpenApiReference
                        
                        Type = ReferenceType.SecurityScheme,
                        Id = "oauth2"
                        ,
                                Scheme = "oauth2",
                                Name = "oauth2",
                                In = ParameterLocation.Header
                     ,
                        new List<string>()
                     
                );
                
            ;
            opts.ClientId = configuration["AzureAd:ClientId"];
            
            opts.OAuth2RedirectPath = "http://localhost:7071/api/swagger/ui/o2c-html";
            //configuration["AzureAd:redirectURI"];
            
        );
        
        builder.Services.AddLogging();

       
    

swagger Ui 生成。但是，当我单击授权时，它会重定向到 redirect.html 并说未找到。 This localhost page can't be found 没有找到该网址的网页：http://localhost:7071/api/swagger/ui/o2c-html#

【问题讨论】：

我认为您需要在门户网站和应用程序中提供以 /swagger/oauth2-redirect.html 结尾的重定向网址。您尝试过吗？

您在 Azure 函数中使用哪个包进行 Swagger 配置？如果您使用的是this 包，那么我相信您应该使用this 线程中讨论的一些解决方法。

@kavyasaraboju-MT 是在门户网站和应用程序中提供了重定向 url。没有帮助

你最后改成/oauth2-redirect.html了吗（请检查你是否在这两个地方都有https协议）。如果完成，您是否通过授予管理员同意公开了范围并为添加的范围添加了权限。还要检查重定向 uri 的类型。您能否检查这些并提供有关相同的屏幕截图/代码详细信息
