我有两个版本的网络表单。原始的，在 VB 中。而新的，在 C# 中。它们本质上都做同样的事情，但语言不同，C# 版本在功能和可读性方面有所改进。通过@Page 标记上的autoeventwireup 属性，每个.aspx 页面本身的差异是不同的。现在，当我尝试运行 VB 版本时，我得到了我正在寻找的结果。 C# 版本什么都不做。在每个页面的日志中，我看到 VB 版本正在从调用者那里获取 POST，而 C# 版本正在从调用者那里获取 GET。因此，C# 版本中没有任何 Request.Form 值可用。部署后的两个页面都由单独的 Web 应用程序调用。
VB版页面.aspx:
<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Custom Label Generator.aspx.vb" Inherits="_Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>Untitled Page</title>
</head>
<body>
<form id="form1" runat="server">
<div>
</div>
</form>
</body>
</html>
page.aspx 的 C# 版本
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Custom Label Generator.aspx.cs" Inherits="CustomLabelGenerator.Custom_Label_Generator" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">

<title>Custom Label Generator</title>
</head>
<body>
<form id="form1" runat="server">
<div>
</div>
</form>
</body>
</html>
VB版本代码隐藏:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
'LogEvent("Request to print: " & Date.Today)
Try
If Request.Form.Count <= 0 Then
LogEvent("No label data was submitted with the request.")
Exit Sub
End If
'WRITE LABEL DATA BACK TO REQUESTING CLIENT
Me.Response.Clear()
Me.Response.ContentType = "text/plain"
Me.Response.BinaryWrite(System.Text.Encoding.Default.GetBytes(sLabelCode))
Me.Response.Flush()
Catch ex As Exception
LogEvent("Problem generating custom labels. More information: " + ex.Message)
End Try
End Sub
C# 版本代码隐藏:
protected void Page_Load(object sender, EventArgs e)
{
LogHelper.LogEvent("Request to print at: " + DateTime.Now);
try
{
if(Request.Form.Count <= 0)
{
LogHelper.LogEvent("No label data was submitted with the request");
return;
}
Response.Clear();
Response.ContentType = "text/plain";
Response.BinaryWrite(Encoding.Default.GetBytes(labelCode));
Response.Flush();
}
catch (Exception ex)
{
LogHelper.LogEvent("Problem generating custom labels. More information :: " + ex.Message);
}
finally
{
LogHelper.CleanupOldLogs();
}
}
我目前有一堆代码可以吐出我能想到的所有请求信息。我也尝试过撤消 autoeventwireup，但在 C# 中似乎没有可靠的等价物。我想知道这作为 WebAPI 调用是否会更好，强制它只接受 POST，而不是与任何其他 kruft 混为一谈。不过，我不确定我是否有时间进行这种级别的转换，因此将不胜感激基于网络表单的解决方案!
更新:从 VB 版本转储 Request.Form.Keys(减去我需要的有用的键)

请您参考如下方法:
马特，
我以前也遇到过神秘地变成“GET”的“POST”。由于 VS2013 及更高版本中默认的 FriendlyUrlSettings，它可能被重定向。
一种解决方法:转到 RouteConfig.ResgisterRoutes 中的 App_Start 文件夹并设置 settings.AutoRedirectMode = RedirectMode.Off
public static class RouteConfig
{
public static void RegisterRoutes(RouteCollection routes)
{
var settings = new FriendlyUrlSettings();
settings.AutoRedirectMode = RedirectMode.Off;
routes.EnableFriendlyUrls(settings);
}
}
