在dotnet核心web api ::ffff:127.0.0.1中获取客户端IP地址

string ipAddress = HttpContext.Connection.RemoteIpAddress.ToString();

services.AddHttpContextAccessor();

private readonly IHttpContextAccessor _httpContextAccessor;

public YourController(IHttpContextAccessor httpContextAccessor)
{
    _httpContextAccessor = httpContextAccessor;
}

public IActionResult YourAction()
{
    string ipAddress = _httpContextAccessor.HttpContext.Connection.RemoteIpAddress.ToString();
    // 其他逻辑
}

app.UseForwardedHeaders(new ForwardedHeadersOptions
{
    ForwardedHeaders = ForwardedHeaders.XForwardedFor
});

string ipAddress = HttpContext.Request.Headers["X-Forwarded-For"];
