我的项目结构的概述:
我有两个项目。
Web Api项目中的
LoginAction
方法将对数据库中的用户进行身份验证,并生成JWT令牌。生成令牌
[AllowAnonymous]
[Route("requesttoken")]
[HttpPost]
public async Task<IActionResult> RequestToken([FromBody] TokenRequest request)
{
var result = await IsValidUser(request);
if(result)
{
var claims = new[]
{
new Claim(ClaimTypes.Name, request.Email)
};
var key = new SymmetricSecurityKey(Encoding.ASCII.GetBytes(_myAppSettings.SecurityKey));
var creds = new SigningCredentials(key, SecurityAlgorithms.HmacSha256);
var token = new JwtSecurityToken(
issuer: _myAppSettings.WebsiteName.ToLower(),
audience: _myAppSettings.WebsiteName.ToLower(),
claims: claims,
notBefore: Utilities.GetEST_DateTimeNow(),
expires: Utilities.GetEST_DateTimeNow().AddMinutes(5),
signingCredentials: creds);
return Ok(new
{
token = new JwtSecurityTokenHandler().WriteToken(token)
});
}
else
{
return Unauthorized();
}
}
启动类中的
// This method gets called by the runtime. Use this method to add services to the container.
public void ConfigureServices(IServiceCollection services)
{
services.Configure<MyAppSettings>(Configuration.GetSection("MyAppSettings"));
#region Validate JWT Token
ConfigureJwtAuthService(services, Configuration);
#endregion
services.AddMvc();
}
// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
app.UseAuthentication();
app.UseMvc();
}
JWT验证部分(作为部分启动类)
public void ConfigureJwtAuthService(IServiceCollection services, IConfiguration configuration)
{
var symmetricKeyAsBase64 = configuration["MyAppSettings:SecurityKey"];
var keyByteArray = Encoding.ASCII.GetBytes(symmetricKeyAsBase64);
var signingKey = new SymmetricSecurityKey(keyByteArray);
var tokenValidationParameters = new TokenValidationParameters
{
// The signing key must match!
ValidateIssuerSigningKey = true,
IssuerSigningKey = signingKey,
// Validate the JWT Issuer (iss) claim
ValidateIssuer = true,
ValidIssuer = Configuration["MyAppSettings:WebsiteName"].ToLower(),
// Validate the JWT Audience (aud) claim
ValidateAudience = true,
ValidAudience = Configuration["MyAppSettings:WebsiteName"].ToLower(),
// Validate the token expiry
ValidateLifetime = true,
ClockSkew = TimeSpan.Zero
};
services.AddAuthentication(
options =>
{
options.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme;
options.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme;
})
.AddJwtBearer(o => o.TokenValidationParameters = tokenValidationParameters);
}
LoginAction方法的样本响应。 { "token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkrDtGhuIETDs8OoIiwiYWRtaW4iOnRydWV9.469tBeJmYLERjlKi9u6gylb-2NsjHLC_6kZNdtoOGsA" }
Web MVC项目中的
我正在尝试实现如下所示:
{
var claims = new List<Claim>
{
new Claim(ClaimTypes.Name, model.Email)
};
var userIdentity = new ClaimsIdentity(claims, "login");
ClaimsPrincipal principal = new ClaimsPrincipal(userIdentity);
await HttpContext.SignInAsync(CookieAuthenticationDefaults.AuthenticationScheme, principal);
return RedirectToLocal(returnUrl);
}
问题
我把
项目中从JWT获取声明,以便能够使用cookie登录用户?
想要以正确的方式来做,任何帮助都会非常感谢。

以下内容似乎对我很有帮助:http://blogs.quovantis.com/json-web-token-jwt-with-web-api/不确定这是不是正确的做法。
/// Using the same key used for signing token, user payload is generated back
public JwtSecurityToken GenerateUserClaimFromJWT(string authToken)
{
var tokenValidationParameters = new TokenValidationParameters()
{
ValidAudiences = new string[]
{
"http://www.example.com",
},
ValidIssuers = new string[]
{
"self",
},
IssuerSigningKey = signingKey
};
var tokenHandler = new JwtSecurityTokenHandler();
SecurityToken validatedToken;
try {
tokenHandler.ValidateToken(authToken,tokenValidationParameters, out validatedToken);
}
catch (Exception)
{
return null;
}
return validatedToken as JwtSecurityToken;
}
