在Swashbuckle中启用Oauth2客户端凭据流-Java 学习之路

我使用IdentityServer3来保护具有客户端凭据授权的Web API . 对于文档我使用Swashbuckle但无法弄清楚如何在SwaggerConfig中为客户端凭据（应用程序）流启用Oauth2 . 任何帮助，将不胜感激！

我在使这一切工作时遇到了一些麻烦，但经过大量的坚持后，我找到了一个无需将任何JavaScript注入SwaggerUI的解决方案 . 注意：我的部分困难可能是由于使用IdentityServer3，这是一个很棒的产品，只是不知道配置问题 .

我的大多数更改都类似于上面的账单回答，但我的操作过滤器是不同的 . 在我的控制器中，所有方法都有一个没有角色的Authorize标签，如下所示：

[Authorize]
// Not this
[Authorize(Roles = "Read")] // This doesn't work for me.

如果Authorize标记上没有定义Roles，则OperationFilter如下所示：

public void Apply(Operation operation, SchemaRegistry schemaRegistry, ApiDescription apiDescription)
    {
        // Correspond each "Authorize" role to an oauth2 scope, since I don't have any "Roles" defined, this didn't work
        // and is in most of the Apply methods I found online.  If you are like me and your [Authorize] tag doesn't contain
        // any roles this will not work.
        //var scopes = apiDescription.ActionDescriptor.GetFilterPipeline()
        //    .Select(filterInfo => filterInfo.Instance)
        //    .OfType<AuthorizeAttribute>()
        //    .SelectMany(attr => attr.Roles.Split(','))
        //    .Distinct();

        var scopes = new List<string>() { "Read" }; // For me I just had one scope that is added to all all my methods, you might have to be more selective on how scopes are added.

        if (scopes.Any())
        {
            if (operation.security == null)
                operation.security = new List<IDictionary<string, IEnumerable<string>>>();

            var oAuthRequirements = new Dictionary<string, IEnumerable<string>>
            {
                { "oauth2", scopes }
            };

            operation.security.Add(oAuthRequirements);
        }
    }

SwaggerConfig看起来像这样：

public static void Register()
{
    var thisAssembly = typeof(SwaggerConfig).Assembly;
    GlobalConfiguration.Configuration
        .EnableSwagger(c =>
        {
           c.SingleApiVersion("v1", "waPortal");
           c.OAuth2("oauth2")
                .Description("OAuth2 Client Credentials Grant Flow")
                .Flow("application")
                .TokenUrl("http://security.RogueOne.com/core/connect/token")
                .Scopes(scopes =>
                {
                    scopes.Add("Read", "Read access to protected resources");
                });
            c.IncludeXmlComments(GetXmlCommentsPath());
            c.UseFullTypeNameInSchemaIds();
            c.DescribeAllEnumsAsStrings();
            c.OperationFilter<AssignOAuth2SecurityRequirements>();
        })
        .EnableSwaggerUi(c =>
        {
            c.EnableOAuth2Support(
                clientId: "swaggerUI",
                clientSecret: "BigSecretWooH00",
                realm: "swagger-realm",
                appName: "Swagger UI"
            );
        });
}

最后一部分是最难以弄清楚的，我最终在Chrome开发者工具的帮助下做了这一点，在网络标记上显示了一点红色X，显示以下错误消息：

XMLHttpRequest cannot load http://security.RogueOne.com/core/connect/token. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:62561' is therefore not allowed access.

我在这里描述了这个错误Swagger UI not parsing reponse，这是由于IdentityServer3正确没有添加“Access-Control-Allow-Origin：http://localhost:62561”的响应头，您可以通过将客户端创建更新为以下内容来强制IdentityServer3发送该头：

new Client
{
    ClientName = "SwaggerUI",
    Enabled = true,
    ClientId = "swaggerUI",
    ClientSecrets = new List<Secret>
    {
        new Secret("PasswordGoesHere".Sha256())
    },
    Flow = Flows.ClientCredentials,
    AllowClientCredentialsOnly = true,
    AllowedScopes = new List<string>
    {
        "Read"
    },

    Claims = new List<Claim>
    {
        new Claim("client_type", "headless"),
        new Claim("client_owner", "Portal"),
        new Claim("app_detail", "allow")
    },
    PrefixClientClaims = false
    // Add the AllowedCorOrigins to get the Access-Control-Allow-Origin header to be inserted for the following domains
    ,AllowedCorsOrigins = new List<string>
    {
        "http://localhost:62561/"
        ,"http://portaldev.RogueOne.com"
        ,"https://portaldev.RogueOne.com"
    }
}

AllowedCorsOrigins是我拼图的最后一块 . 希望这可以帮助面临同样问题的其他人

我能够让这个工作 . 大部分答案都可以找到here .

我必须更改一些部分才能使client_credential授权生效 . 第一部分是在EnableSwagger和EnableSwaggerUi调用中：

config.EnableSwagger(c => 
  {
    c.SingleApiVersion("v1", "sample api");
    c.OAuth2("oauth2")
     .Description("client credentials grant flow")
     .Flow("application")
     .Scopes(scopes => scopes.Add("sampleapi", "try out the sample api"))
     .TokenUrl("http://authuri/token");
    c.OperationFilter<AssignOAuth2SecurityRequirements>();
  }).EnableSwaggerUi(c =>
  {
    c.EnableOAuth2Support("sampleapi", "samplerealm", "Swagger UI");
  });

这里重要的变化是 .Flow("application") 我也使用了 .TokenUrl 调用而不是 .AuthorizationUrl 这只是依赖于您设置的特定授权方案 .

我也使用了稍微不同的 AssignOAuth2SecurityRequirements 类

public class AssignOAuth2SecurityRequirements : IOperationFilter
{
    public void Apply(Operation operation, SchemaRegistry schemaRegistry, ApiDescription apiDescription)
    {
      var authorized = apiDescription.ActionDescriptor.GetCustomAttributes<AuthorizeAttribute>();
      if (!authorized.Any()) return;

      if (operation.security == null)
          operation.security = new List<IDictionary<string, IEnumerable<string>>>();

      var oAuthRequirements = new Dictionary<string, IEnumerable<string>>
      {
          {"oauth2", Enumerable.Empty<string>()}
      };

      operation.security.Add(oAuthRequirements);
    }
}

这应足以让身份验证开关显示 . 另一个问题是我设置了默认的身份验证对话框，因此用户只需选择一个范围，然后单击“授权” . 在我的情况下，由于我设置了身份验证的方式，这不起作用 . 我不得不在swagger-oauth.js脚本中重新编写对话框并将其注入SwaggerUI .
