Question

我有一组AJAX代码，代码调用Perl脚本和脚本有一些功能。每当我点击拨号按钮Perl脚本应该运行但我无法运行脚本。当我点击拨号按钮我完整的Perl程序正在Web上显示。另一方面，当我强行执行我的程序时，它正确执行。

如果您正在使用Apache并在Linux服务器上运行，那么以下可能帮助。

您可能需要以下.htaccess文件和Perl代码：

<FilesMatch "\.pl$">
  Options +ExecCGI

  SetHandler cgi-script
</FilesMatch>

为此，您还需要确保Perl脚本是可执行的：

chmod 755 myscript.pl

..并且脚本的第一行是这样的：

#!/usr/bin/perl

我无法在ajax中执行perl脚本
