在电子邮件中包含 cron 作业脚本输出

Question

我有一个 python 脚本，当通过命令行运行时，它的输出如下所示：

Content-type: application/json

        },

我在 Crontab 中配置的 cron 作业如下所示：

MAILTO = my@email.com

*/15 * * * * /home/local/COMPANY/malvin/SilverChalice_CampusInsiders/SilverChalice_Parser.py > /home/local/COMPANY/malvin/SilverChalice_CampusInsiders`date +\%Y-\%m-\%d-\%H:\%M:\%S`-cron.log | mailx -s "SilverChalice CampusInsiders" my@email.com

我可以确认 cron 作业正在运行，因为它确实在指定目录中创建了具有预期输出的 cron 日志。但是，我在电子邮件中看到的是：

Null message body; hope that's ok

我在 Crontab 中做错了什么？如何强制我的 py 脚本的输出显示在电子邮件正文中？

Answer 1

crontab 行应该是：

*/15 * * * * /home/local/COMPANY/malvin/SilverChalice_CampusInsiders/SilverChalice_Parser.py | tee /home/local/COMPANY/malvin/SilverChalice_CampusInsiders`date +\%Y-\%m-\%d-\%H:\%M:\%S`-cron.log | mailx -s "SilverChalice CampusInsiders" my@email.com

tee 将写入其文件名参数以及 stdout，后者将通过管道传输至 mailx 命令。
