Response.StatusCode问题 [英] Response.StatusCode problem
问题描述
您好。我需要使用http标头StatusCode作为响应。
例如我的页面有名称check.aspx我得到这样的请求
check.aspx？idcustomer = 1395
我使用这个idcustomer param来检查我的数据库中是否存在此客户
以及是否存在显示页面（http StatusCode == 200），但如果客户编号为
1395不存在我需要make 404 http错误（页面不存在）
我想要做类似的事情
protected void Page_Load（object sender，EventArgs e）
{
Response.StatusCode = 404;
Response.End（）;
}
但它不起作用。你可以帮助我吗？
不确定为什么你试图以这种方式使用Response.StatusCode。
你可以做的是在你的SQL中如果没有找到用户返回零然后
检查大于零的值并执行你想要的任何动作
返回价值。
问候，

忘了sql。这只是一个例子。问题是如何从现有页面发送http 404
响应？

Hello. I need use http header StatusCode as response.
For example my page have name check.aspx and I get request like this
check.aspx?idcustomer=1395
I use this idcustomer param to check if this customer exist in my database
and if exist show page (http StatusCode == 200), but if customer with number
1395 not exist I need make 404 http error (page not exist)
I am tring to do something like
protected void Page_Load(object sender, EventArgs e)
{
Response.StatusCode = 404;
Response.End();
}
but it doesn''t work. Can you somebody help me with it?
Not sure why you are attempting to use Response.StatusCode in this manner.
What you could do is in you SQL if the user was not found return zero then
check for values greater then zero and perform whatever action you wish from
the returned value.

Forget about sql. It is just example. The question is how I can send http 404
response from exist page?
