Why do I get different results from the form post method “GET” vs. the “POST” method in the following?
Question
I have the following HTML/ASP.NET code:
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Ny test</title>
<link rel="stylesheet" type="text/css" href="StyleSheet.css" />
</head>
<body>
<form action="Default.aspx" runat="server" method="post">
Name: <input type="text" id="navn" runat="server"/>
<input type="submit" id="submit" value="Submit!" runat="server" />
<input type="reset" />
<br />
<%if (Request.Form["submit"] != null)
{
Response.Write("<br/>");
Response.Write("Submit button pushed");
}
if (Request.Form["navn"] != null && Request.Form["navn"] != "")
{
Response.Write("<br/>");
Response.Write("Name OK");
}
%>
</form>
</body>
</html>
When using the "POST" form post method I get the following output:
Submit button pushed Name OK
When using the "GET" form post method NOTHING is printed out?!

Request.Form contains information that is sent using POST . When you use GET the information will be in the Request.QueryString collection. In your case this means that Request.Form["submit"] is null .
If you want to support both then you would be able to use the Request.Item collection which includes values from:
-
Request.Cookies -
Request.Form -
Request.QueryString -
Request.ServerVariables
However, doing this you may get some unexpected results if you use a parameter name that is used in one of the other collections.

要使用您的代码处理POST和GET ，您只需删除.Form ，即用Request["navn"]替换Request.Form["navn"] Request["navn"] 。
