How can I send some http request from postgresql f

问题:

I need to send data via http protocol (GET or POST request) from the function or trigger. Is it possible?

回答1:

You could try writing the trigger in PL/Python and use urllib2 to POST.

回答2:

There is an extension to do this, use with caution.

pgsql-http

回答3:

Any "untrusted" language with HTTP support can do this:

• PL/Pythonu
• PL/perlu
• PL/javau
• ...

but you shouldn't really do it. See Does PLV8 support making http calls to other servers? and why you shouldn't send email from a trigger function.
