所以我只是添加了一个将我的网站列入白名单的系统。这是我的 Global.asax。我评论了麻烦的地方
#region Application Methods
private List<string> _approvedIps = new List<string>();
protected void Application_BeginRequest()
{
//This is obviously called afterwards
//But when I examine the list at a breakpoint the count is 0. WHY?!?!?
Debug.WriteLine("User from ip: {0}", Request.UserHostAddress);
if (!_approvedIps.Contains(Request.UserHostAddress))
{
Debug.WriteLine("Unauthorized user. Access Denied");
Response.Clear();
Response.StatusCode = (int) HttpStatusCode.Unauthorized;
Response.End();
}
}
protected void Application_Start()
{
string path = Path.Combine(Server.MapPath("~"), "whitelist.txt");
using (var reader = new StreamReader(path))
{
while (reader.Peek() > 0)
{
string l = reader.ReadLine(); //Reader here works fine and at a breakpoint
_approvedIps.Add(l); //I can see the count of 2
}
}
Database.SetInitializer(new IYCDataDBInit(50));
AreaRegistration.RegisterAllAreas();
RegisterGlobalFilters(GlobalFilters.Filters);
RegisterRoutes(RouteTable.Routes);
BundleTable.Bundles.RegisterTemplateBundles();
}
#endregion
我只是不明白为什么我会遇到这个问题。据我了解，在调用 Application_start 之后，列表应该被填满，然后 _BeginRequest 方法可以访问。
