我在ASP.NET Core 1.0中创建了一个REST api。我正在使用Swagger进行测试,但现在我为某些路线添加了JWT授权。 (使用UseJwtBearerAuthentication
)
是否可以修改Swagger请求的标头,以便可以测试具有[Authorize]
属性的路由?
答案 0 :(得分:30)
我遇到了同样的问题,并在这篇博文中找到了一个有效的解决方案: http://blog.sluijsveld.com/28/01/2016/CustomSwaggerUIField
归结为在配置选项中添加此内容
services.ConfigureSwaggerGen(options =>
{
options.OperationFilter<AuthorizationHeaderParameterOperationFilter>();
});
以及operationfilter的代码
public class AuthorizationHeaderParameterOperationFilter : IOperationFilter
{
public void Apply(Operation operation, OperationFilterContext context)
{
var filterPipeline = context.ApiDescription.ActionDescriptor.FilterDescriptors;
var isAuthorized = filterPipeline.Select(filterInfo => filterInfo.Filter).Any(filter => filter is AuthorizeFilter);
var allowAnonymous = filterPipeline.Select(filterInfo => filterInfo.Filter).Any(filter => filter is IAllowAnonymousFilter);
if (isAuthorized && !allowAnonymous)
{
if (operation.Parameters == null)
operation.Parameters = new List<IParameter>();
operation.Parameters.Add(new NonBodyParameter
{
Name = "Authorization",
In = "header",
Description = "access token",
Required = true,
Type = "string"
});
}
}
}
然后,您将在swagger中看到一个额外的授权文本框,您可以在其中添加您的令牌,格式为“Bearer {jwttoken}&#39;并且你应该在你的招摇要求中获得授权。

目前,Swagger具有使用JWT令牌进行身份验证的功能,并且可以自动将令牌添加到标头中(我使用Swashbuckle.AspNetCore 1.1.0)。
以下代码应该有助于实现这一目标。
在Startup.ConfigureServices()中:
services.AddSwaggerGen(c =>
{
// Your custom configuration
c.SwaggerDoc("v1", new Info { Title = "My API", Version = "v1" });
c.DescribeAllEnumsAsStrings();
// JWT-token authentication by password
c.AddSecurityDefinition("oauth2", new OAuth2Scheme
{
Type = "oauth2",
Flow = "password",
TokenUrl = Path.Combine(HostingEnvironment.WebRootPath, "/token"),
// Optional scopes
//Scopes = new Dictionary<string, string>
//{
// { "api-name", "my api" },
//}
});
});
如果您的终端不同,请检查并配置 TokenUrl 。
在Startup.Configure()中:
app.UseSwagger();
app.UseSwaggerUI(c =>
{
c.SwaggerEndpoint("/swagger/v1/swagger.json", "API V1");
// Provide client ID, client secret, realm and application name (if need)
// Swashbuckle.AspNetCore 4.0.1
c.OAuthClientId("swagger-ui");
c.OAuthClientSecret("swagger-ui-secret");
c.OAuthRealm("swagger-ui-realm");
c.OAuthAppName("Swagger UI");
// Swashbuckle.AspNetCore 1.1.0
// c.ConfigureOAuth2("swagger-ui", "swagger-ui-secret", "swagger-ui-realm", "Swagger UI");
});
如果您通过令牌进行身份验证的端点遵循OAuth2标准,则所有端点都应该有效。但为了以防万一,我添加了这个端点的样本:
public class AccountController : Controller
{
[ProducesResponseType(typeof(AccessTokens), (int)HttpStatusCode.OK)]
[ProducesResponseType((int)HttpStatusCode.BadRequest)]
[ProducesResponseType((int)HttpStatusCode.Unauthorized)]
[HttpPost("/token")]
public async Task<IActionResult> Token([FromForm] LoginModel loginModel)
{
switch (loginModel.grant_type)
{
case "password":
var accessTokens = // Authentication logic
if (accessTokens == null)
return BadRequest("Invalid user name or password.");
return new ObjectResult(accessTokens);
case "refresh_token":
var accessTokens = // Refresh token logic
if (accessTokens == null)
return Unauthorized();
return new ObjectResult(accessTokens);
default:
return BadRequest("Unsupported grant type");
}
}
}
public class LoginModel
{
[Required]
public string grant_type { get; set; }
public string username { get; set; }
public string password { get; set; }
public string refresh_token { get; set; }
// Optional
//public string scope { get; set; }
}
public class AccessTokens
{
public string access_token { get; set; }
public string refresh_token { get; set; }
public string token_type { get; set; }
public int expires_in { get; set; }
}

扩展对我有用的HansVG答案(谢谢),因为我没有足够的贡献点,所以我不能直接回答emseetea问题。获得授权文本框后,您将需要调用生成令牌的端点,该令牌将位于端点的必须[授权]区域之外。
一旦调用该端点以从端点生成令牌,您就可以将其从该端点的结果中复制出来。然后你有令牌在你必须[授权]的其他区域使用。只需将其粘贴到文本框中即可。正如HansVG所提到的那样,确保以正确的格式添加它,其中需要包含“bearer”。 Format =“bearer {token}”。

感谢Pavel K.'s answer,这是我终于在带有Swagger 4.0.1的ASP.NET Core 2.2中解决了此问题的方式。
在Startup.cs ConfigureServices()中:
public void ConfigureServices(IServiceCollection services)
{
.
.
.
services.AddSwaggerGen(c =>
{
c.SwaggerDoc("v1", new Info { Title = "...", Version = "v1" });
.
.
.
c.AddSecurityDefinition("Bearer", new OAuth2Scheme
{
Flow = "password",
TokenUrl = "/token"
});
// It must be here so the Swagger UI works correctly (Swashbuckle.AspNetCore.SwaggerUI, Version=4.0.1.0)
c.AddSecurityRequirement(new Dictionary<string, IEnumerable<string>>
{
{"Bearer", new string[] { }}
});
});
.
.
.
}
在Startup.cs Configure()中:
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
.
.
.
app.UseSwagger();
app.UseSwaggerUI(c =>
{
c.SwaggerEndpoint("/swagger/v1/swagger.json", "...");
// Provide client ID, client secret, realm and application name (if need)
c.OAuthClientId("...");
c.OAuthClientSecret("...");
c.OAuthRealm("...");
c.OAuthAppName("...");
});
.
.
.
}
这是我制作端点以发出JWT令牌的方式:
[ApiController, Route("[controller]")]
public class TokenController : ControllerBase
{
[HttpPost, AllowAnonymous]
public async Task<ActionResult<AccessTokensResponse>> RequestToken([FromForm]LoginRequest request)
{
var claims = await ValidateCredentialAndGenerateClaims(request);
var now = DateTime.UtcNow;
var securityKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(_setting.SecurityKey));
var signingCredentials = new SigningCredentials(securityKey, SecurityAlgorithms.HmacSha256);
var token = new JwtSecurityToken(
issuer: _setting.Issuer,
audience: _setting.Audience,
claims: claims,
notBefore: now,
expires: now.AddMinutes(_setting.ValidDurationInMinute),
signingCredentials: signingCredentials);
return Ok(new AccessTokensResponse(token));
}
}
关于验证用户名和密码(和/或client_id和clinet_secret)的所有规则和逻辑将在ValidateCredentialAndGenerateClaims()
中。
如果您只是想知道,这些是我的请求和响应模型:
/// <summary>
/// Encapsulates fields for login request.
/// </summary>
/// <remarks>
/// See: https://www.oauth.com/oauth2-servers/access-tokens/
/// </remarks>
public class LoginRequest
{
[Required]
public string grant_type { get; set; }
public string username { get; set; }
public string password { get; set; }
public string refresh_token { get; set; }
public string scope { get; set; }
public string client_id { get; set; }
public string client_secret { get; set; }
}
/// <summary>
/// JWT successful response.
/// </summary>
/// <remarks>
/// See: https://www.oauth.com/oauth2-servers/access-tokens/access-token-response/
/// </remarks>
public class AccessTokensResponse
{
/// <summary>
/// Initializes a new instance of <seealso cref="AccessTokensResponse"/>.
/// </summary>
/// <param name="securityToken"></param>
public AccessTokensResponse(JwtSecurityToken securityToken)
{
access_token = new JwtSecurityTokenHandler().WriteToken(securityToken);
token_type = "Bearer";
expires_in = Math.Truncate((securityToken.ValidTo - DateTime.UtcNow).TotalSeconds);
}
public string access_token { get; set; }
public string refresh_token { get; set; }
public string token_type { get; set; }
public double expires_in { get; set; }
}

您可以使用此swagger configuration
通过API调用添加任何其他标头// Register the Swagger generator, defining 1 or more Swagger documents
services.AddSwaggerGen(c =>
{
c.SwaggerDoc("v1", new Info
{
Version = "v1",
Title = "Core API",
Description = "ASP.NET Core API",
TermsOfService = "None",
Contact = new Contact
{
Name = "Raj Kumar",
Email = ""
},
License = new License
{
Name = "Demo"
}
});
c.AddSecurityDefinition("Bearer", new ApiKeyScheme()
{
Description = "JWT Authorization header using the Bearer scheme. Example: \"Authorization: Bearer {token}\"",
Name = "Authorization",
In = "header",
Type = "apiKey"
});
c.AddSecurityRequirement(new Dictionary<string, IEnumerable<string>>
{
{"Bearer",new string[]{}}
});
});

我还将检查 AuthorizeAttribute 。
var filterDescriptor = context.ApiDescription.ActionDescriptor.FilterDescriptors;
var hasAuthorizedFilter = filterDescriptor.Select(filterInfo => filterInfo.Filter).Any(filter => filter is AuthorizeFilter);
var allowAnonymous = filterDescriptor.Select(filterInfo => filterInfo.Filter).Any(filter => filter is IAllowAnonymousFilter);
var hasAuthorizedAttribute = context.MethodInfo.ReflectedType?.CustomAttributes.First().AttributeType ==
typeof(AuthorizeAttribute);
if ((hasAuthorizedFilter || hasAuthorizedAttribute) && !allowAnonymous)
{
var oAuthScheme = new OpenApiSecurityScheme
{
Reference = new OpenApiReference { Type = ReferenceType.SecurityScheme, Id = "Bearer" }
};
operation.Security = new List<OpenApiSecurityRequirement>
{
new OpenApiSecurityRequirement
{
[ oAuthScheme ] = new List<string>()
}
};
}
控制器操作:
[Authorize(Policy = AppConfiguration.PermissionReadWrite)]
[Route("api/[controller]")]
[ApiController]
public class FooController : ControllerBase
{
...
}
