Question

 if (Request.QueryString["Username"] != null)
    {
        Login1.UserName =Request.QueryString["Username"];
        Login1.Password = Request.QueryString["Password"];
     if (FormsAuthentication.Authenticate(Login1.UserName, Login1.Password))
        {
            FormsAuthentication.RedirectFromLoginPage(Login1.UserName, true);

        }

    }
     else{

        if (FormsAuthentication.Authenticate(Login1.UserName, Login1.Password))
        {
            FormsAuthentication.RedirectFromLoginPage(Login1.UserName, true);

        }
        }

如何将querystring密码传递给Login1.Password.I我正在使用FormsAuthentication方法登录。但是Login1.Password不接受来自querystring的值.Is Login1.Password会给出打字错误吗？请帮忙

Answer 1

您不需要Authenticate的登录控件，请将用户名和密码作为参数

string username= Request.QueryString["Username"];
string password = Request.QueryString["Password"];

if (FormsAuthentication.Authenticate(username, password))
{
    FormsAuthentication.RedirectFromLoginPage(username, true);
}

但不建议将密码作为查询字符串发送，最好阅读How to safely include password in query string

您可以直接将查询字符串参数传递给Forms Authentication Authenticate函数，如下所示

if (Request.QueryString["Username"] != null && Request.QueryString["Password"] != null)
{

    if (FormsAuthentication.Authenticate(Request.QueryString["Username"].ToString(), Request.QueryString["Password"].ToString()))
    {
        // Authentication successful code

        FormsAuthentication.RedirectFromLoginPage(Request.QueryString["Username"].ToString(), true);
    }
    else
    {
        // Authentication unsuccessful code
    }
}
else
{
    // Parameter invalid or missing code
}
