我对WebAPi身份验证很陌生,尽管OWIN似乎很受欢迎。我不明白为什么我应该使用EntityFramework进行OWIN身份验证,因为ApplicationDbContext是从IdentityDbContext派生而来的,而IdentityDbContext在EntityFramework命名空间中。以下是当我们在WebApi项目模板中选择个人用户帐户时自动创建的过程:
public partial class Startup
{
public static OAuthAuthorizationServerOptions OAuthOptions { get; private set; }
public static string PublicClientId { get; private set; }
// For more information on configuring authentication, please visit http://go.microsoft.com/fwlink/?LinkId=301864
public void ConfigureAuth(IAppBuilder app)
{
// Configure the db context and user manager to use a single instance per request
app.CreatePerOwinContext(ApplicationDbContext.Create);
app.CreatePerOwinContext<ApplicationUserManager>(ApplicationUserManager.Create);
// Enable the application to use a cookie to store information for the signed in user
// and to use a cookie to temporarily store information about a user logging in with a third party login provider
app.UseCookieAuthentication(new CookieAuthenticationOptions());
app.UseExternalSignInCookie(DefaultAuthenticationTypes.ExternalCookie);
// Configure the application for OAuth based flow
PublicClientId = "self";
OAuthOptions = new OAuthAuthorizationServerOptions
{
TokenEndpointPath = new PathString("/Token"),
Provider = new ApplicationOAuthProvider(PublicClientId),
AuthorizeEndpointPath = new PathString("/api/Account/ExternalLogin"),
AccessTokenExpireTimeSpan = TimeSpan.FromDays(14),
// In production mode set AllowInsecureHttp = false
AllowInsecureHttp = true
};
// Enable the application to use bearer tokens to authenticate users
app.UseOAuthBearerTokens(OAuthOptions);
// Uncomment the following lines to enable logging in with third party login providers
//app.UseMicrosoftAccountAuthentication(
// clientId: "",
// clientSecret: "");
//app.UseTwitterAuthentication(
// consumerKey: "",
// consumerSecret: "");
//app.UseFacebookAuthentication(
// appId: "",
// appSecret: "");
//app.UseGoogleAuthentication(new GoogleOAuth2AuthenticationOptions()
//{
// ClientId = "",
// ClientSecret = ""
//});
}
}
在ConfigureAuth过程中,引用了ApplicationDbContext。
你能帮我用OWIN写简单的身份验证而不使用EntityFramework吗?
谢谢。
您不需要使用EF,是的,模板使用EF和ASPNET Identity来进行身份验证,但您可以开始使用黑色模板并添加它而不使用EF,查看以下代码部分:
- 启动.cs
public class Startup
{
public void Configuration(IAppBuilder app)
{
HttpConfiguration config = new HttpConfiguration();
ConfigureOAuth(app);
WebApiConfig.Register(config);
app.UseCors(Microsoft.Owin.Cors.CorsOptions.AllowAll);
app.UseWebApi(config);
}
public void ConfigureOAuth(IAppBuilder app)
{
OAuthAuthorizationServerOptions OAuthServerOptions = new OAuthAuthorizationServerOptions()
{
AllowInsecureHttp = true,
TokenEndpointPath = new PathString("/token"),
AccessTokenExpireTimeSpan = TimeSpan.FromDays(1),
Provider = new SimpleAuthorizationServerProvider()
};
// Token Generation
app.UseOAuthAuthorizationServer(OAuthServerOptions);
app.UseOAuthBearerAuthentication(new OAuthBearerAuthenticationOptions());
}
}
- SimpleAuthorizationServerProvider.cs
public class SimpleAuthorizationServerProvider : OAuthAuthorizationServerProvider
{
public override async Task ValidateClientAuthentication(OAuthValidateClientAuthenticationContext context)
{
context.Validated();
}
public override async Task GrantResourceOwnerCredentials(OAuthGrantResourceOwnerCredentialsContext context)
{
context.OwinContext.Response.Headers.Add("Access-Control-Allow-Origin", new[] { "*" });
if (context.UserName != "Admin")
{
context.SetError("upps!", "Wrong data");
return;
}
var identity = new ClaimsIdentity(context.Options.AuthenticationType);
identity.AddClaim(new Claim("sub", context.UserName));
identity.AddClaim(new Claim("role", "user"));
context.Validated(identity);
}
}
