Question

我的经典ASP网站上有一些简单的代码，当页面出错时向我发送电子邮件，因为我在web.config中设置了这个以指向页面来处理错误：

<httpErrors errorMode="Custom" defaultResponseMode="ExecuteURL">
    <remove statusCode="500" subStatusCode="100" />
    <remove statusCode="500" subStatusCode="-1" />
    <remove statusCode="404" subStatusCode="-1" />
    <error statusCode="404" path="/error_404.asp" responseMode="ExecuteURL" />
    <error statusCode="500" prefixLanguageFilePath="" path="/error_500.asp" responseMode="ExecuteURL" />
    <error statusCode="500" subStatusCode="100" path="/error_500.asp" responseMode="ExecuteURL" />
</httpErrors>

这是我的一小段代码：

...
set objError =          Server.getLastError()
strNumber =             objError.AspCode
strSource =             objError.Category
strDesc =               newstr(objError.Description)
strCode =               newstr(objError.Source)
strLine =               ObjError.Line
strASPDesc =            ObjError.ASPDescription
strRemoteAddr =         Request.ServerVariables("REMOTE_ADDR")
ref =                   request.servervariables("HTTP_REFERER")
str =                   request.servervariables("QUERY_STRING")
cookies =               request.servervariables("HTTP_COOKIE")
ip_url =                strRemoteAddr
ua =                    newstr(request.servervariables("HTTP_USER_AGENT"))
totalstring =           objError.File & "?" & str

然后我将这些值连接在一起并通过电子邮件将详细信息发送给自己。

对于错误，我会得到类似的结果：

strNumber: ASP 0126
strSource: Active Server Pages
strDesc: Include file not found
strCode:
strLine: 14
strASPDesc: The include file '/news/aw.asp' was not found.
strRemoteAddr: 2.101.166.175

str: page=cd

但是，我经常只看到这个错误：

strNumber:
strSource:
strDesc:
strCode:
strLine: 0
strASPDesc:
strRemoteAddr: 43.247.156.6
ref: http:/example.com/content/this.asp

totalstring: ?500;http:/example.com:80/content/this.asp

此处没有错误详细信息，但它始终位于同一页面上。我无法解决导致它的原因。

我可以做更详细的错误记录以了解更多信息吗？

Answer 1

Server.getLastError()仅在响应缓冲区开始向客户端刷新内容之前保持填充状态，原因可能是：

response.buffer设置为false
response.flush被称为
response.end被称为

文档中提到了这一点：

This method is available only before the .asp file has sent any content to the client.

这是我能想到的唯一可以解释为什么你的Server.getLastError()似乎是空白的。
