Question

我刚刚设置了一个代理页面来处理ajax请求但我无法让它工作，因为cookie根本没有得到保存。我的代码如下：

public partial class JsonProxy : System.Web.UI.Page
{

private string username;
private string password;
private int idPlant;
private string mode;

protected void Page_Load(object sender, EventArgs e)
{
    try
    {
        username = !String.IsNullOrEmpty(HttpUtility.UrlDecode(Request.Form["username"])) ? HttpUtility.UrlDecode(Request.Form["username"].ToString()) : string.Empty;
        password = !String.IsNullOrEmpty(HttpUtility.UrlDecode(Request.Form["password"])) ? HttpUtility.UrlDecode(Request.Form["password"].ToString()) : string.Empty;
        idPlant = !String.IsNullOrEmpty(HttpUtility.UrlDecode(Request.Form["idPlant"])) ? int.Parse(HttpUtility.UrlDecode(Request.Form["idPlant"].ToString())) : 0;
        mode = !String.IsNullOrEmpty(HttpUtility.UrlDecode(Request.Form["mode"])) ? HttpUtility.UrlDecode(Request.Form["mode"].ToString()) : string.Empty;

        string response = "";
        HttpWebRequest wc;

        if (!String.IsNullOrEmpty(username) && !String.IsNullOrEmpty(password) && idPlant != 0 && !String.IsNullOrEmpty(mode))
        {
            //First do authentication
            wc= (HttpWebRequest)WebRequest.Create("http://10.255.255.10/Base/Authentication/Login/" + username + "/" + password + ".aspx");
            wc.Method = "GET";

            StreamReader  reader = new StreamReader(((HttpWebResponse)wc.GetResponse()).GetResponseStream());
            if (reader.ReadToEnd().Contains("true"))
            {
                //Then check that authentication succeded
                wc = (HttpWebRequest)WebRequest.Create("http://10.255.255.10/Base/Authentication/IsAuthenticated.aspx");
                wc.Method = "GET";

                reader = new StreamReader(((HttpWebResponse)wc.GetResponse()).GetResponseStream());

                string str = reader.ReadToEnd();
                if (str.Contains("true"))
                {
                    //Then make BP request
                    string methodName = "/Base/BusinessPlan/GetBPAlll/" + idPlant + ".aspx";
                    wc = (HttpWebRequest)WebRequest.Create("http://10.255.255.10" + methodName);
                    wc.Method = "GET";
                    reader = new StreamReader(((HttpWebResponse)wc.GetResponse()).GetResponseStream());
                    response = reader.ReadToEnd();
                }
            }

        }

        //Last: write response
        Response.ContentType = "application/json";
        Response.Write(response);
    }
    catch (WebException ex)
    {
        Response.Write("error");
    }
}

}

登录请求应在客户端创建一些cookie，用于下一个请求（IsAuthenticated）和最后一个（实际的实际请求）。但是IsAuthenticated在我正确登录后才返回false（我可以看到它按预期返回true）。就像我从未登录过所以问题是：如何在代理中保存cookie？我愿意接受考虑HttpHandlers或其他理论的答案来做ajax代理，不一定是Aspx。
注意：如果我制作相同的请求系列，我可以看到cookie被创建，所以它必须是我的aspx代理的问题

Answer 1

在这种情况下，cookie不会保存在客户端中，因为这是发出请求的服务器代码。 Cookie将作为响应的一部分发送到您的服务器，但不会发送回客户端我想要获得您希望的行为，您需要从初始响应中获取cookie集合对象，并将其复制到以下两个请求对象中。

进一步搜索后，我发现您需要手动将cookiesContainer传递给下一个请求者。这是完整而有效的例子：

public partial class JsonProxy : System.Web.UI.Page

{

private string username;
private string password;
private int idPlant;
private string mode;
private CookieContainer cookieJar = new CookieContainer();

protected void Page_Load(object sender, EventArgs e)
{
    try
    {
        username = !String.IsNullOrEmpty(HttpUtility.UrlDecode(Request.Form["username"])) ? HttpUtility.UrlDecode(Request.Form["username"].ToString()) : string.Empty;
        password = !String.IsNullOrEmpty(HttpUtility.UrlDecode(Request.Form["password"])) ? HttpUtility.UrlDecode(Request.Form["password"].ToString()) : string.Empty;
        idPlant = !String.IsNullOrEmpty(HttpUtility.UrlDecode(Request.Form["idPlant"])) ? int.Parse(HttpUtility.UrlDecode(Request.Form["idPlant"].ToString())) : 0;
        mode = !String.IsNullOrEmpty(HttpUtility.UrlDecode(Request.Form["mode"])) ? HttpUtility.UrlDecode(Request.Form["mode"].ToString()) : string.Empty;

        string response = "";
        HttpWebRequest wc;

        if (!String.IsNullOrEmpty(username) && !String.IsNullOrEmpty(password) && idPlant != 0 && !String.IsNullOrEmpty(mode))
        {
            //First do authentication
            wc= (HttpWebRequest)WebRequest.Create("http://10.255.255.10/Base/Authentication/Login/" + username + "/" + password + ".aspx");
            wc.Method = "GET";
            wc.CookieContainer = cookieJar;

            StreamReader  reader = new StreamReader(((HttpWebResponse)wc.GetResponse()).GetResponseStream());
            if (reader.ReadToEnd().Contains("true"))
            {
                //Then check that authentication succeded
                wc = (HttpWebRequest)WebRequest.Create("http://10.255.255.10/Base/Authentication/IsAuthenticated.aspx");
                wc.Method = "GET";
                wc.CookieContainer = cookieJar;

                reader = new StreamReader(((HttpWebResponse)wc.GetResponse()).GetResponseStream());

                string str = reader.ReadToEnd();
                if (str.Contains("true"))
                {
                    //Then make BP request
                    string methodName = "/Base/BusinessPlan/GetBPAll/" + idPlant + ".aspx";
                    wc = (HttpWebRequest)WebRequest.Create("http://10.255.255.10" + methodName);
                    wc.Method = "GET";
                    wc.CookieContainer = cookieJar;
                    reader = new StreamReader(((HttpWebResponse)wc.GetResponse()).GetResponseStream());
                    response = reader.ReadToEnd();
                }
            }
        }

        //Last: write response
        Response.ContentType = "application/json";
        Response.Write(response);
    }
    catch (WebException ex)
    {
        Response.ContentType = "application/json";
        Response.Write("error");
    }
}

}

再见！
