如何从 32 位 ASP 应用程序查询 Windows 2008 x64 索引服务？

最近我偶然发现一个问题，涉及将 ASP 经典站点从 w2k3 服务器移动到 w2k8 64 环境。它涉及到让索引服务与 asp classic 一起使用。我到处寻找，尝试了很多解决方案，但都失败了。

问题：在 32 位应用程序池上运行 64 位索引服务（对于 asp classic）向索引服务运行请求的 ASP 页会导致服务器对象无法加载的错误。尽管索引服务正在运行，并且包含索引站点文档的文件夹正在以 64 位模式运行，而池以 32 位模式运行。不可能跑了。

一些建议的解决方案是重写代码以使用新的“windows 搜索”，但由于这也在 64 位中运行，因此无法在 32 位应用程序模式下运行。在池中切换到 32 位兼容模式会导致 ASP 站点使用的数据库和其他 com 对象无法工作。

几天后，我几乎要放弃了，但在半夜，我想到了一个绝妙的主意，让一切顺利进行。如果我对以 64 位模式运行的 Web 服务器上的子域进行 ajax 调用，并且虚拟目录包含以 32 位应用程序模式运行的站点的索引目录，该怎么办？

第二天，经过不安的睡眠后，我开始工作，在 IIS7 中添加了一个新的子域，将虚拟目录添加到网站的索引目录中。并添加了一个包含请求处理程序的“indexer.asp”页面。

    dim ajaxresult

    next

    ajaxresult=Left(ajaxresult,Len(ajaxresult)-1)
    response.write ajaxresult
end if


%>

然后我在以 32 位应用程序模式运行的网站之一上发出了一个请求页面：

dim FSOA 'return documents file array

'search inside documents 
sub DoSearchText(target, indexservice)
'target = search string
'indexservice = catalog name (index service)

dim IndexArray() 'one dimensional array for index result
dim xmlhttp, tempArray, IndexUrl

'url to the 64bit indexer subdomain
IndexURL = ("http://indextest.subdomain.local/indexer.asp?Index="&IndexService&"&Search="&target&"&Size=50") 
set xmlhttp = CreateObject("MSXML2.ServerXMLHTTP") 
xmlhttp.open "GET", IndexURL, false 
xmlhttp.send ""  

if xmlhttp.status >= 400 and xmlhttp.status <=599 then
    response.write " error processing: " &xmlhttp.status &" - "&xmlhttp.statusText
else
    tempArray= xmlhttp.responseText 
end if

set xmlhttp = nothing  
'put result into a array
FSOA= split(tempArray,"|")
end Sub


call DoSearchText("chapter one", "sitebooks")

if isarray(FSOA) then

    dim docloop
    for each docloop in FSOA
        response.write "<div>"&docloop&"</div>"
    next
else
    response.write "No documents found"
end if

说明：

解析索引服务目录名称、搜索字符串、最大结果文档
在子域中创建虚拟目录（命名为索引目录）），重定向到已编入索引的目录的原始位置
添加一个处理请求调用的indexer.asp页面，
更改原始网页的现有请求对象代码，以对上述子域进行ajax调用

好处：

从以 32 位应用程序模式运行的 ASP 经典网站向 64 位应用程序发出 Ajax 请求并返回结果。
您还可以添加 adobe PDF Ifilter（64 位）来索引 PDF并阅读 PDF 文件内部。
轻松更改网站现有的 asp 代码。小改动
在单独的 64 位池和子域上运行索引器
添加多个目录，在一个位置上轻松维护
将不可能变为可能：在 32 位应用程序模式下运行带有 64 位索引服务的 asp classic

After a couple of days I almost given up but in the middle of the night I got a brilliant idea to get it all working. What if I make a ajax call to a sub domain on the webserver which is running in 64bit mode with virtual directories containing the indexed directories of the sites running in 32bit application mode.

Next day after a restless sleep I got to work, added a new subdomain in IIS7 added virtual directories to the indexed directories of the websites. and added a 'indexer.asp' page which contains a request handler.

    ajaxresult=Left(ajaxresult,Len(ajaxresult)-1)
    response.write ajaxresult

Then I made a request page on one of the websites running in 32bit application mode:

dim FSOA 'return documents file array

'search inside documents 
sub DoSearchText(target, indexservice)
'target = search string
'indexservice = catalog name (index service)

dim IndexArray() 'one dimensional array for index result
dim xmlhttp, tempArray, IndexUrl

'url to the 64bit indexer subdomain
IndexURL = ("http://indextest.subdomain.local/indexer.asp?Index="&IndexService&"&Search="&target&"&Size=50") 
set xmlhttp = CreateObject("MSXML2.ServerXMLHTTP") 
xmlhttp.open "GET", IndexURL, false 
xmlhttp.send ""  

if xmlhttp.status >= 400 and xmlhttp.status <=599 then
    response.write " error processing: " &xmlhttp.status &" - "&xmlhttp.statusText
else
    tempArray= xmlhttp.responseText 
end if

set xmlhttp = nothing  
'put result into a array
FSOA= split(tempArray,"|")
end Sub


call DoSearchText("chapter one", "sitebooks")

if isarray(FSOA) then

    dim docloop
    for each docloop in FSOA
        response.write "<div>"&docloop&"</div>"
    next
else
    response.write "No documents found"
end if

Explanation:

Parse indexing service catalog name, search string, max resulted documents
In subdomain create virtual directories (named as the index catalog) that redirects to the original location of the directory that has been indexed
Add a indexer.asp page that handles the request calls
alter existing request object code of original webpage to make a ajax call to above subdomain

Benefits:

Make a Ajax request from asp classic website running in 32bit application mode to a 64bit application and return results.
You can also include adobe PDF Ifilter (64bit) to index PDF and read inside PDF files.
Easy to alter existing asp code of sites. Minor changes
Run indexer on separate 64bit pool and subdomain
Add multiple catalogs easy maintained on one location
Making the impossible possible: running asp classic with 64bit indexing service in 32bit application mode
