很多公司都有这样的需求，希望系统可以定时邮件发送一些统计报表给到相关人员，以便做数据分析，或者是希望做单时，发送单据内容给到相关人员提醒审核和备案，下面分享一种十分简单方便的实现方式，javamail+4gl+perl脚本实现;
1:在aooi999配置好系统标准的javamail 功能，测试可以正常发送报表邮件，配置方式可以百度
2:添加邮件发送功能函数，可以参考cl_prt里面的发邮件功能，我简化了一些东西代码如下：

LET l_index = l_text.getIndexOf('successfully',1)

END IF END FUNCTION 

代码可以独立做一个公用函数，其他函数调用的时候只需要传入g_xml数组就能实现自动发邮件了

里面写的是将数据抓取出来后，先以字串形式写入到一个txt文档，最后通过perl转换成EXCEL档，再将以附件的形式发送到指定收件人，嗯，就是这样！

附上perl脚本代码：

#!/usr/bin/perl -w
use strict;
use Spreadsheet::WriteExcel;
#use Text::CSV::Encoded;
use Encode;
if (($#ARGV < 1) || ($#ARGV > 2)) {die("Usage: csv2xls txtfile.txt newfile.xls\n");
};my $workbook  = Spreadsheet::WriteExcel->new($ARGV[2]);# Open the Comma Separated Variable fileopen  CSVFILE, '<:utf8', $ARGV[0] or die "$ARGV[0]: $!";my $worksheet = $workbook->add_worksheet('Scrap_list');my $row = 0;$worksheet->set_column(0,5,14);while (<CSVFILE>) {s/[\001-\037]//g;my @list = split /\|\*\|/,$_;my $col = 0;foreach my $token (@list) {if  ($token=~/^0[^.]/) {$worksheet->write_string($row, $col, $token );}else{ $worksheet->write($row, $col, $token);}$col++;}$row++;}close(CSVFILE);$workbook->close();
