我正在开发一个项目，我们已经开始将项目移动到最终服务器进行生产。我们根本没有更改代码，但excel导出无法正常工作。当我们打开导出的文件时，它会出现“不可读的内容”错误。当我单击是以更正它时，将excel留空甚至没有显示空白电子表格。看看excel错误日志，我似乎找不到任何指向问题的东西。
我已经开始评论代码，一旦我注释掉从服务器获取数据并将它们放在excel文件中的行，文件就会正常工作。这再次在我们的DEV环境中运行良好，但我知道他们正在使用不同类型的服务器。
Dev Env - 使用apache web服务器的2008 SQL Server Prod Env - 使用apache web服务器的2012 SQL Server

正如你所看到的那样，我现在已经将数据拉出来了（我已经在各个变量被拉入的所有位置都列出了“变量”，并且我仔细检查以确保变量是正确的。我甚至尝试了一个一个留下一个数据拉变量工作，看看我是否能找到它只是其中一个有困难的项目。
我也尝试将文件类型更改为.xslx无效。
与2008年相比，2012年的机器是否有特定的东西可能导致这个问题？或者您是否在代码中发现可能是我的问题的问题。
