Question

为了解决“Cookies已禁用”问题，我使用了 CookieContainer myContainer = new CookieContainer（）; request.CookieContainer = myContainer; 这在首次调用getIDfromWeb函数时有效。但是，再次调用getIDfromWeb函数时，会出现“Cookies disabled”。我该如何解决这个问题？要重现相同的问题，当您不包含“request.CookieContainer = myContainer”时，您需要满足“Cookies已禁用”问题。否则您的网址可能不需要身份验证。虽然我可以通过将我的URL放在IE地址栏上并按Enter键来获取信息，但是在从C＃实现时遇到了授权错误。我使用httpwebrequest和cookie来解决问题但发现我第二次调用该函数时遇到了“Cookies禁用”问题。

它为我工作。

此处更新了您的代码，请检查。

static void Main(string[] args)
    {
        Console.WriteLine("Key1 sample:");
        Console.WriteLine(getIDfromWeb("key1"));
        Console.WriteLine("key1. sample2:");
        Console.WriteLine(getIDfromWeb("key2"));
        Console.ReadKey();
    }

替换下面的行

Console.WriteLine(getIDfromWeb("key2"));

为什么在再次调用相同的Httprequest函数时会出现“Cookies禁用”？
