builder.Services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme) .AddJwtBearer(options => { options.TokenValidationParameters = new TokenValidationParameters { ValidateIssuer = true, ValidateAudience = true, ValidateLifetime = true, ValidateIssuerSigningKey = true, ValidIssuer = "your_issuer", // 发行者 ValidAudience = "your_audience", // 受众 IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes("your_secret_key")) // 密钥 }; });改为APPSETINGSC传入

要将JWT认证配置从代码中移到appsettings.json文件中，可以按照以下步骤进行操作：

1. 在appsettings.json文件中添加JWT认证配置：

{
  "JwtSettings": {
    "Issuer": "your_issuer",
    "Audience": "your_audience",
    "SecretKey": "your_secret_key"
  }
}

2. 在Startup.cs文件的ConfigureServices方法中，注册并读取JWT认证配置：

// 添加配置文件支持
var configuration = new ConfigurationBuilder()
    .SetBasePath(env.ContentRootPath)
    .AddJsonFile("appsettings.json")
    .Build();

// 读取JWT认证配置
var jwtSettings = configuration.GetSection("JwtSettings").Get<JwtSettings>();

// 添加JWT认证服务
services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme)
    .AddJwtBearer(options =>
    {
        options.TokenValidationParameters = new TokenValidationParameters
        {
            ValidateIssuer = true,
            ValidateAudience = true,
            ValidateLifetime = true,
            ValidateIssuerSigningKey = true,
            ValidIssuer = jwtSettings.Issuer,
            ValidAudience = jwtSettings.Audience,
            IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(jwtSettings.SecretKey))
        };
    });

// 注册JwtSettings配置
services.Configure<JwtSettings>(configuration.GetSection("JwtSettings"));

3. 创建一个JwtSettings类来存储JWT认证配置：

public class JwtSettings
{
    public string Issuer { get; set; }
    public string Audience { get; set; }
    public string SecretKey { get; set; }
}

这样，你就可以将JWT认证的配置从代码中移到appsettings.json文件中，并通过依赖注入的方式读取配置。确保将"your_issuer"、"your_audience"和"your_secret_key"替换为你的实际值。
