Question

我需要在ASPX（VB版本）中从POST方法读取变量。

这里是代码：

<!DOCTYPE html>
<html>
    <script runat="server">
        Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
            Response.Write("[POST]<br />")
            For Each s As String In Request.Form.AllKeys
                Response.Write("[Request.Form] " & s & ": " & Request.Form(s) & "<br />")
            Next
            Response.Write("[GET] <br />")
            For Each a As String In Request.QueryString.AllKeys
                Response.Write("[Request.QueryString] " & a & ": " & Request(a) & "<br />")
            Next
        End Sub
</script>
<body>
<form action="demo_simpleform.aspx" method="post">
    <input name="infob" type="text" value="POST" id="infob" disabled />
    <input name="TextBox1" type="text" value="" id="TextBox1" />
    <input name="TextBox2" type="password" id="TextBox2" />
    <input type="submit" value="Method POST" />
</form>
<form action="demo_simpleform.aspx" method="get">
    <input name="infoa" type="text" value="GET" id="infoa" disabled />
    <input name="TextBox1a" type="text" value="" id="TextBox1a" />
    <input name="TextBox2a" type="password" id="TextBox2a"/>
    <input type="submit" value="Method GET"/>
</form>
</body>
</html>

为什么我无法读取POST变量？怎么了？帮助我，请

我找到了解决方案（但我不明白为什么......）

我必须将FORM action =“demo_simpleform.aspx”method =“post”转换为FORM runat =“server”。好的，我明白必须插入runat =“server”参数（在表单声明中和表单中的所有对象中），但为什么我要删除action =“demo_simpleform.aspx”method =“post”？

这是工作代码：

<!DOCTYPE html>
<html>
    <script runat="server">
        Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
            Response.Write("[POST]<br />")
            For Each s As String In Request.Form.AllKeys
                Response.Write("[Request.Form] " & s & ": " & Request.Form(s) & "<br />")
            Next
            Response.Write("[GET] <br />")
            For Each a As String In Request.QueryString.AllKeys
                Response.Write("[Request.QueryString] " & a & ": " & Request(a) & "<br />")
            Next
        End Sub
</script>
<body>
<form runat="server">
    <input runat="server" name="infob" type="text" value="POST 2" id="infob" disabled />
    <input runat="server" name="TextBox1" type="text" value="" id="TextBox1" />
    <input runat="server" name="TextBox2" type="password" id="TextBox2" />
    <input runat="server" type="submit" value="Method POST 2" />
</form>
<form action="demo_simpleform.aspx" method="get">
    <input name="infoa" type="text" value="GET" id="infoa" disabled />
    <input name="TextBox1a" type="text" value="" id="TextBox1a" />
    <input name="TextBox2a" type="password" id="TextBox2a"/>
    <input type="submit" value="Method GET"/>
</form>
</body>
</html>

使用ASPX vb.net读取POST变量
