为特定页面指定 MaxHttpCollectionKeys 的方法是使用路由参数进行传递。在 ASP.NET Core 中,可以使用 RouteAttribute
来指定一个路由。
具体实现步骤如下:
Startup.cs
中,为需要传递 MaxHttpCollectionKeys 的页面添加路由。using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.Mvc;
namespace YourNamespace
{
public class Startup
{
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
// ...
app.UseEndpoints(endpoints =>
{
// Add the MaxHttpCollectionKeys route for the page with ID 1
endpoints.Map("/page-with-maxhc", builder =>
{
builder.Run(async context =>
{
context.Response.StatusCode = 200;
context.Response.ContentType = "text/html";
var maxHttpCollectionKeys = 10000;
context.Request.Headers.Add("MaxHttpCollectionKeys", maxHttpCollectionKeys);
await context.Response.WriteAsync("<html><body><h1>Page with MaxHttpCollectionKeys</h1></body></html>");
});
});
});
}
}
}
HttpContext.Request.Headers.Get("MaxHttpCollectionKeys")
获取 MaxHttpCollectionKeys 的值。using Microsoft.AspNetCore.Mvc;
namespace YourNamespace.Controllers
{
public class MyController : Controller
{
public IActionResult PageWithMaxHttpCollectionKeys()
{
var maxHttpCollectionKeys = HttpContext.Request.Headers.Get("MaxHttpCollectionKeys");
ViewData["MaxHttpCollectionKeys"] = maxHttpCollectionKeys;
return View();
}
}
}
ViewData["MaxHttpCollectionKeys"]
获取 MaxHttpCollectionKeys 的值。<!DOCTYPE html>
<html>
<head>
<title>Page with MaxHttpCollectionKeys</title>
</head>
<body>
<h1>Page with MaxHttpCollectionKeys</h1>
<p>MaxHttpCollectionKeys: <span id="max-http-collection-keys"></span></p>
<script>
// Get the MaxHttpCollectionKeys value from the page
var maxHttpCollectionKeys = parseInt(document.getElementById("max-http-collection-keys").innerHTML);
// Use the MaxHttpCollectionKeys value in your JavaScript code
</script>
</body>
</html>
通过这种方法,可以在 ASP.NET Core 中为特定页面传递 MaxHttpCollectionKeys 的值。
