在Ruby上使用WIN32OLE從Remote Server渲染Word文檔

Question

當我當時使用win32ole作為獨立應用程序時，一切似乎都正常運行，一旦我將其放入運行在mongrel服務器上的rails應用程序中，就會陷入無限循環。

我正在嘗試訪問“ https：//microsoft/sharepoint/document.doc”

def generatertm(issue) 
begin 
  word = WIN32OLE.new('word.application') 
  logger.debug("Word Initialized...") 
  word.visible = true 
  myDocLink = "https://microsoft/sharepoint/url.doc" 
  myFile = word.documents.open(myDocLink) 
  logger.debug("File Opened...") 
  puts "Started Reading bookmarks..." 
  myBookMarks = myFile.Bookmarks puts "bookmarks fetched working background task..."

  print ("Bookmakr Count : " + myBookMarks.Count.to_s + "\n")

  myBookMarks.each do |i|
    logger.warn ("Bookmark Name : " + i.Name + "\n")
  end
rescue WIN32OLERuntimeError => e
  puts e.message
  puts e.backtrace.inspect
  else
ensure

word.activedocument.close( true )  # presents save dialog box
#word.activedocument.close(false) # no save dialog, just close it
word.quit
end
end

當我當時單獨運行此代碼時，將彈出一個彈出窗口，以獲取Microsoft共享點憑據。 但是在雜種軌道中，它會陷入無限循環。

我是否需要處理此彈出窗口才能通過Rails出現？

您是否研究過修補win32ole.rb文件？

基本上，這是補丁的原因：

事實證明，win32ole.rb修補了線程，以圍繞該塊的收益率調用Windows OleInitialize（）和OleUninitialize（）函數。 但是，CoInitialize的MS文檔（OleInitialize在內部對其進行調用）指出：“應用程序中調用CoInitialize的值為0（或CoInitializeEx的值為COINIT_APARTMENTTHREADED）的第一個線程必須是調用CoUninitialize的最后一個線程。否則，后續對CoInitialize的調用STA將失敗，應用程序將無法運行。” http://msdn.microsoft.com/zh-CN/library/ms678543(v=VS.85).aspx

這是修改后的win32ole.rb文件，用於解決線程問題：

require 'win32ole.so'

# Fail if not required by main thread.
# Call OleInitialize and OleUninitialize for main thread to satisfy the following:
#
# The first thread in the application that calls CoInitialize with 0 (or CoInitializeEx with COINIT_APARTMENTTHREADED)
# must be the last thread to call CoUninitialize. Otherwise, subsequent calls to CoInitialize on the STA will fail and the
# application will not work.
#
# See http://msdn.microsoft.com/en-us/library/ms678543(v=VS.85).aspx
if Thread.main != Thread.current
  raise "Require win32ole.rb from the main application thread to satisfy CoInitialize requirements."
else
  WIN32OLE.ole_initialize
  at_exit { WIN32OLE.ole_uninitialize }
end


# re-define Thread#initialize
# bug #2618(ruby-core:27634)

class Thread
  alias :org_initialize :initialize
  def initialize(*arg, &block)
    if block
      org_initialize(*arg) {
        WIN32OLE.ole_initialize
        begin
          block.call(*arg)
        ensure
          WIN32OLE.ole_uninitialize
        end
      }
    else
      org_initialize(*arg)
    end
  end
end
