一、使用HttpContextAccessor
在Program.cs中增加一行:
//获取IP使用
builder.Services.AddSingleton<IHttpContextAccessor, HttpContextAccessor>();
var builder = WebApplication.CreateBuilder(args); // Add services to the container. builder.Services.AddControllersWithViews(); //获取IP使用 builder.Services.AddSingleton<IHttpContextAccessor, HttpContextAccessor>(); var app = builder.Build(); // Configure the HTTP request pipeline. if (!app.Environment.IsDevelopment()) { app.UseExceptionHandler("/Home/Error"); } app.UseStaticFiles(); app.UseRouting(); app.UseAuthorization(); app.MapControllerRoute( name: "default", pattern: "{controller=Home}/{action=Index}/{id?}"); app.Run();
修改Controller:
private readonly IHttpContextAccessor _httpContextAccessor;
_httpContextAccessor = httpContextAccessor;
var ip = _httpContextAccessor.HttpContext.Connection.RemoteIpAddress.ToString();
using AspNetCoreMvcclientIp2.Models; using Microsoft.AspNetCore.Mvc; using System.Diagnostics; namespace AspNetCoreMvcclientIp2.Controllers { public class HomeController : Controller { private readonly ILogger<HomeController> _logger; private readonly IHttpContextAccessor _httpContextAccessor; public HomeController(ILogger<HomeController> logger, IHttpContextAccessor httpContextAccessor) { _logger = logger; _httpContextAccessor = httpContextAccessor; } public IActionResult Index() { //注入 var ip = _httpContextAccessor.HttpContext.Connection.RemoteIpAddress.ToString(); ViewBag.myip = "ip:" + ip; //直接实例化HttpContextAccessor IHttpContextAccessor ih = new HttpContextAccessor(); string ip2 = ih.HttpContext.Connection.RemoteIpAddress.ToString(); ViewBag.myip = "ip2:" + ip2; //使用ControllerBase的HttpContext var ip3 = HttpContext.Connection.RemoteIpAddress.ToString(); ViewBag.myip = "ip3:" + ip3; return View(); } public IActionResult Privacy() { return View(); } [responsecache(Duration = 0, Location = responsecacheLocation.None, NoStore = true)] public IActionResult Error() { return View(new Errorviewmodel { RequestId = Activity.Current?.Id ?? HttpContext.TraceIdentifier }); } } }
也可以直接实例化HttpContextAccessor:
//直接实例化HttpContextAccessor IHttpContextAccessor ih = new HttpContextAccessor(); string ip2 = ih.HttpContext.Connection.RemoteIpAddress.ToString(); ViewBag.myip = "ip2:" + ip2;
二、使用ControllerBase的HttpContext
//使用ControllerBase的HttpContext var ip3 = HttpContext.Connection.RemoteIpAddress.ToString(); ViewBag.myip = "ip3:" + ip3;
