lynx cronjob调用，但HTTP请求未发送

Question

I am running a cronjob every 30 minutes from my shared hosting to another of my ec2 server using the following command:-

0,30 * * * * /usr/bin/lynx http://qwerty.com/crons/myCron.php

The cron job does run every 30 minutes based on the emails I am receiving from the Cron Daemon. But then the PHP file seems to be called sometimes only. I noticed that it's only successful when the HTTP request is sent in the Cron Daemon email I receive.

Examples are shown below:-

How can I make sure that the HTTP request is sent each time the cron daemon runs?

Answer 1

You could try forcing a dump however this will also dump all the HTML from the page.. Might not be applicable. -dump dumps the formatted output of the default document or one specified on the command line to standard out. Under UNIX this can be used in the following way:

lynx -dump http://qwerty.com/crons/myCron.php

Or

/usr/bin/lynx -mime_header -dump http://qwerty.com/crons/myCron.php

Alternatively you could try wget with several tries to ensure full response ..

/usr/bin/wget −r −−tries=10 http://qwerty.com/crons/myCron.php

Again you could try cURL :

curl http://qwerty.com/crons/myCron.php

Any of these options viable for you ?
