Question

我知道这个问题已经回答了很多次，但是在将值从Winform发布到ASPX页面时，我仍然遇到问题。我总是得到null值。

以下是我的winform代码：

string formContent = "FormValue1=" + contact.Country;

        var dataBytes = System.Text.Encoding.UTF8.GetBytes(formContent);
        HttpWebRequest httpWebRequest = (HttpWebRequest)WebRequest.Create("http://localhost:52262/Default.aspx");
        httpWebRequest.ContentType = "application/x-www-form-urlencoded";           

        httpWebRequest.ContentLength = dataBytes.Length;

        httpWebRequest.Method = WebRequestMethods.Http.Post;

        Stream dataStream = httpWebRequest.GetRequestStream();            

        dataStream.Write(dataBytes, 0, dataBytes.Length);            
        dataStream.Close();
        //dataStream.Flush();

        HttpWebResponse response = (HttpWebResponse)httpWebRequest.GetResponse();

        //lblShow.Text = ((HttpWebResponse)response).StatusDescription;

        Stream responseStream = response.GetResponseStream();

        StreamReader streamReader = new StreamReader(responseStream);

        string responseFromServer = streamReader.ReadToEnd();          

        streamReader.Close();                        
        response.Close();

以下是我的Default.aspx页面代码：

protected void Page_Load(object sender, EventArgs e)
    {
        ClaimsPrincipal claimsPrincipal = Page.User as ClaimsPrincipal;

        if (claimsPrincipal != null)
        {
            this.ClaimsGridView.DataSource = claimsPrincipal.Claims;
            this.ClaimsGridView.DataBind();
        }

        Session["Name"] = Request.Form["FormValue1"];
    }

“请求表单”值始终为空值。相同的代码在MVC中有效，但在Webforms中始终会失败。

任何帮助或指导都是很好的。

在此先感谢!!! ..

如果您在网站上启用了FriendlyURLS，它将干扰Request.Form的收集：

以防上述URL停止工作：

修改友好URL的配置您将在App_Start文件夹的RouteConfig.cs文件中找到它。要更改的配置是自动重定向模式，默认情况下设置为RedirectMode.Permanent。注释掉此设置：

public static void RegisterRoutes(RouteCollection routes)
{
    var settings = new FriendlyUrlSettings();
    //settings.AutoRedirectMode = RedirectMode.Permanent;
    routes.EnableFriendlyUrls(settings);
}
