从asp.net内核中间件的类和方法属性中获取值

using Microsoft.AspNetCore.Http;

public class MyMiddleware
{
    private readonly RequestDelegate _next;

    public MyMiddleware(RequestDelegate next)
    {
        _next = next;
    }

    public async Task Invoke(HttpContext context)
    {
        // 获取请求路径
        string path = context.Request.Path;

        // 获取请求方法
        string method = context.Request.Method;

        // 获取请求头信息
        string userAgent = context.Request.Headers["User-Agent"];

        // 获取请求参数
        string queryParam = context.Request.Query["param"];

        // 打印获取到的值
        Console.WriteLine($"Path: {path}");
        Console.WriteLine($"Method: {method}");
        Console.WriteLine($"User-Agent: {userAgent}");
        Console.WriteLine($"QueryParam: {queryParam}");

        // 调用下一个中间件
        await _next(context);
    }
}
