Question

我想在ASP.NET Core 2.2中使用JWT身份验证，我从邮递员的正文和标头发送令牌，但收到401错误，

用于创建令牌的代码：

var signature = new SymmetricSecurityKey(Encoding.UTF8.GetBytes("Test API For JWT Authentication in ASP.NET Core 2.2"));
var header = new SigningCredentials(signature, SecurityAlgorithms.HmacSha256);
var payload = new JwtSecurityToken(claims: new List<Claim>
{
    new Claim(ClaimTypes.Name, userInfo.Username)

} , signingCredentials:header);

var token = new JwtSecurityTokenHandler().WriteToken(payload);

return token;

startup.cs配置：

services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme)
        .AddJwtBearer(options =>
        {
            options.TokenValidationParameters = new TokenValidationParameters()
            {
                ValidateIssuer = true,
                ValidateAudience = false,
                ValidateIssuerSigningKey = true,
                IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes("Test API For JWT Authentication in ASP.NET Core 2.2"))
            };
        });

services.AddCors(options =>
{
    options.AddPolicy("Cors", builder =>
    {
        builder.AllowAnyOrigin()
               .AllowAnyHeader()
               .AllowAnyMethod()
               .Build();
    });
});

确保您的请求中是否包含authorization标头，其值为Bearer access_token：

Authentication: Bearer KJVG32532UVBU78V...

将JWT从客户端发送到服务器
