在ASP.NET Core 6 Web API中,处理多个令牌请求的方法可以通过自定义中间件来实现。在生成令牌的端点中添加自定义的中间件,以确保在每个请求中进行令牌验证。
以下是一个解决方案的示例代码:
public class TokenRequestMiddleware
{
private readonly RequestDelegate _next;
private readonly IConfiguration _configuration;
public TokenRequestMiddleware(RequestDelegate next, IConfiguration configuration)
{
_next = next;
_configuration = configuration;
}
public async Task Invoke(HttpContext context)
{
var headerValue = context.Request.Headers["Authorization"].ToString();
if (!string.IsNullOrEmpty(headerValue) && headerValue.StartsWith("Bearer"))
{
var token = headerValue.Substring("Bearer ".Length).Trim();
var validationParams = new TokenValidationParameters
{
ValidIssuer = _configuration["JWTIssuer"],
ValidAudience = _configuration["JWTAudience"],
IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(_configuration["JWTSecretKey"]))
};
var handler = new JwtSecurityTokenHandler();
try
{
var claimsPrincipal = handler.ValidateToken(token, validationParams, out var securityToken);
context.Items["User"] = claimsPrincipal;
}
catch (Exception ex)
{
context.Response.StatusCode = (int)HttpStatusCode.Unauthorized;
await context.Response.WriteAsync(ex.Message);
return;
}
}
await _next.Invoke(context);
}
}
app.UseMiddleware();
[Authorize]
[HttpGet("{id}")]
public async Task GetItem(int id)
{
var user = HttpContext.Items["User"] as ClaimsPrincipal;
// More code here
}
这样,就可以在ASP.NET Core 6 Web API中处理多个令牌请求。
