JSF commandButton - passing POST params to an external site

问题

I need a link which redirect me to a different site and send POST parameters. Something like:

  <h:form> 
    <h:commandButton value="submit" action="http://example.com"> 
      <f:param name="user" value="robson"> 
    </h:commandButton> 
  </h:form>

The code above doesn't work of course.

I'd like to acheive this in HTML:

  <form action="http://example.com" method="POST">
    <input type="hidden" name="user" value="robson">
    <input type="submit" value="submit">
  </form>

Is that possible?

回答1:

Use the vanilla HTML <form> tag, not the JSF tag if you're going to send form data to a non-JSF target.

The JSF form tag is designed to facilitate JSF postback operations, which is why it has no "action" attribute.
