详解如何在ASP.NET Core配置请求超时中间件

using Microsoft.AspNetCore.Http.Timeouts;
 
var builder = WebApplication.CreateBuilder(args);
 
// Add services to the container.
 
builder.Services.AddControllers();
 
builder.Services.AddEndpointsApiExplorer();
builder.Services.AddSwaggerGen();
builder.Services.AddRequestTimeouts();
 
var app = builder.Build();
app.UseRequestTimeouts();
 
// Configure the HTTP request pipeline.
if (app.Environment.IsDevelopment())
{
    app.UseSwagger();
    app.UseSwaggerUI();
}
 
app.UseHttpsRedirection();
 
app.UseAuthorization();
 
app.MapControllers();
 
app.MapGet("/", async (HttpContext context) => {
    try
    {
        await Task.Delay(TimeSpan.FromSeconds(10), context.RequestAborted);
    }
    catch (TaskCanceledException)
    {
        return Results.Content("Timeout!", "text/plain");
    }
 
    return Results.Content("No timeout!", "text/plain");
}).WithRequestTimeout(TimeSpan.FromSeconds(2));
// Returns "Timeout!"
 
// 属性将终结点配置为超时
app.MapGet("/attribute",
    [RequestTimeout(milliseconds: 2000)] async (HttpContext context) => {
        try
        {
            await Task.Delay(TimeSpan.FromSeconds(10), context.RequestAborted);
        }
        catch (TaskCanceledException)
        {
            return Results.Content("Timeout!", "text/plain");
        }
 
        return Results.Content("No timeout!", "text/plain");
    });
 
app.Run();
