该项目由两部分组成：

  • ASP.Net核心API

  • ASP.Net核心MVC前端

基本上，我想要做的是通过JWT进行身份验证 . 因此，API发布JWT，MVC前端使用Identity与JWT中声明的声明和角色 .

API中的Startup.cs：

private const string SecretKey = "my_Secret_Key";
private readonly SymmetricSecurityKey _signingKey = new SymmetricSecurityKey(Encoding.ASCII.GetBytes(SecretKey));

            #region JWT Auth


        // jwt wire up
        // Get options from app settings
        var jwtAppSettingOptions = Configuration.GetSection(nameof(JwtIssuerOptions));

        // Configure JwtIssuerOptions
        services.Configure<JwtIssuerOptions>(options =>
        {
            options.Issuer = jwtAppSettingOptions[nameof(JwtIssuerOptions.Issuer)];
            options.Audience = jwtAppSettingOptions[nameof(JwtIssuerOptions.Audience)];
            options.SigningCredentials = new SigningCredentials(_signingKey, SecurityAlgorithms.HmacSha256);
        });

        var tokenValidationParameters = new TokenValidationParameters
        {
            ValidateIssuer = true,
            ValidIssuer = jwtAppSettingOptions[nameof(JwtIssuerOptions.Issuer)],

            ValidateAudience = true,
            ValidAudience = jwtAppSettingOptions[nameof(JwtIssuerOptions.Audience)],

            ValidateIssuerSigningKey = true,
            IssuerSigningKey = _signingKey,


            RequireExpirationTime = false,
            ValidateLifetime = true,
            ClockSkew = TimeSpan.Zero
        };

        services.AddAuthentication(options =>
        {
            options.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme;
            options.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme;

        }).AddJwtBearer(configureOptions =>
        {
            configureOptions.ClaimsIssuer = jwtAppSettingOptions[nameof(JwtIssuerOptions.Issuer)];
            configureOptions.TokenValidationParameters = tokenValidationParameters;
            configureOptions.SaveToken = true;
        });

        // api user claim policy
        services.AddAuthorization(options =>
        {
            options.AddPolicy(Constants.Policies.ApiAccess, policy => policy.RequireClaim(Constants.JwtClaimIdentifiers.Rol, Constants.JwtClaims.ApiAccess));
        });

        #endregion

JWT代：

public async Task<string> GenerateEncodedToken(string userName)
    {

        User user = _userManager.GetUserByUserName(userName);
        List<string> userRoles = _userManager.GetRoles(user.Guid);

        var claimsToEncode = new[]
     {
             new Claim(JwtRegisteredClaimNames.Sub, userName),
             new Claim("web", user.WebId),
             new Claim(JwtRegisteredClaimNames.Jti, await _jwtOptions.JtiGenerator()),
             new Claim(JwtRegisteredClaimNames.Iat, ToUnixEpochDate(_jwtOptions.IssuedAt).ToString(), ClaimValueTypes.Integer64),
             new Claim(Constants.JwtClaimIdentifiers.Rol,Constants.JwtClaims.ApiAccess),
     };


        // Create the JWT security token and encode it.
        var jwt = new JwtSecurityToken(
            issuer: _jwtOptions.Issuer,
            audience: _jwtOptions.Audience,
            claims: claimsToEncode,
            notBefore: _jwtOptions.NotBefore,
            expires: _jwtOptions.Expiration,
            signingCredentials: _jwtOptions.SigningCredentials);


        jwt.Payload.Add("roles", userRoles.ToArray());

        var encodedJwt = new JwtSecurityTokenHandler().WriteToken(jwt);



        return encodedJwt;
    }

授权就像API中的魅力一样 .

现在我想要执行以下操作：在前端实现相同的内容，以便：MVC Frontend接收凭据，将它们发送到API，获取令牌，并使用令牌中的声明和角色进行授权 .

我尝试了几件事，但到目前为止都没有 . 我需要在前端的Startup.cs中插入什么，以便Identity不会检查密钥（前端不允许拥有），而是针对公钥？或者我是否必须在API中实现一个远程验证JWT的 endpoints ？
