1，在Webapi项目下添加如下引用：
Microsoft.AspNet.WebApi.Owin
Owin
Microsoft.Owin.Host.SystemWeb
Microsoft.Owin.Security.OAuth
Microsoft.Owin.Security.COOKIEs
Microsoft.AspNet.Identity.Owin
Microsoft.Owin.Cors
2， 在项目下新建Startup类，这个类将作为owin的启动入口，添加下面的代码
3，修改 Startup类中方法

public class Startup
{ public void Configuration(IAppBuilder app)
{
// 有关如何配置应用程序的详细信息，请访问 http://go.microsoft.com/fwlink/?LinkID=316888
ConfigAuth(app);
HttpConfiguration cOnfig= new HttpConfiguration();
WebApiConfig.Register(config);
app.UseCors(CorsOptions.AllowAll);
app.UseWebApi(config);
}
public void ConfigAuth(IAppBuilder app)
{
OAuthAuthorizationServerOptions option = new OAuthAuthorizationServerOptions()
{
AllowInsecureHttp = true,
TokenEndpointPath = new PathString("/token"), //获取 access_token 授权服务请求地址
AccessTokenExpireTimeSpan = TimeSpan.FromDays(1), //access_token 过期时间
Provider = new SimpleAuthorizationServerProvider(), //access_token 相关授权服务
RefreshTokenProvider = new SimpleRefreshTokenProvider() //refresh_token 授权服务
};
app.UseOAuthAuthorizationServer(option);
app.UseOAuthBearerAuthentication(new OAuthBearerAuthenticationOptions());
}
} |
4， OAuth身份认证，新建SimpleAuthorizationServerProvider类

public class SimpleAuthorizationServerProvider : OAuthAuthorizationServerProvider
{ public override Task ValidateClientAuthentication(OAuthValidateClientAuthenticationContext context)
{
context.Validated();
return Task.FromResult<object>(null);
}
public override async Task GrantResourceOwnerCredentials(OAuthGrantResourceOwnerCredentialsContext context)
{
context.OwinContext.Response.Headers.Add("Access-Control-Allow-Origin", new[] { "*" });
AccountService accService = new AccountService();
string md5Pwd = LogHelper.MD5CryptoPasswd(context.Password);
IList<object[]> ul = accService.Login(context.UserName, md5Pwd);
if (ul.Count() == 0)
{
context.SetError("invalid_grant", "The username or password is incorrect");
return;
}
var identity = new ClaimsIdentity(context.Options.AuthenticationType);
identity.AddClaim(new Claim("sub", context.UserName));
identity.AddClaim(new Claim("role", "user"));
context.Validated(identity);
}
} |
5， 新建SimpleRefreshTokenProvider类

public class SimpleRefreshTokenProvider : AuthenticationTokenProvider
{ private static ConcurrentDictionary<string, string> _refreshTokens = new ConcurrentDictionary<string, string>();
///
/// 生成 refresh_token
///
public override void Create(AuthenticationTokenCreateContext context)
{
context.Ticket.Properties.IssuedUtc = DateTime.UtcNow;
context.Ticket.Properties.ExpiresUtc = DateTime.UtcNow.AddDays(60);
context.SetToken(Guid.NewGuid().ToString("n"));
_refreshTokens[context.Token] = context.SerializeTicket();
}
///
/// 由 refresh_token 解析成 access_token
///
public override void Receive(AuthenticationTokenReceiveContext context)
{
string value;
if (_refreshTokens.TryRemove(context.Token, out value))
{
context.DeserializeTicket(value);
}
}
} |
6， 在要加验证的接口上加上[Authorize]标记

[Authorize]public class EmployeeController : ApiController
{ //查询所有员工
[HttpGet]
public IList
{
return new List
}
} |
7，调用api程序
8,传入参数，获取token
9，传入access_token
