Getting a Page via a POST Request

By

Although the primary method of making POST requests with your web browser or Mechanize is by submitting forms, you can also manually make POST requests with the Mechanize#post method.

To make a POST request with no parameters, simply pass the URL to the Mechanize#post method.


agent.post('http://example.com/update')

However, that's not very interesting. To make a POST request with the request body populated with key/value pairs, pass a hash as the second argument.


agent.post('http://example.com/update'
  { :message => "Hello, world" })

Interestingly, Mechanize also supports multipart/form-data POST request (also known as file uploads). If any of the keys in the hash are IO objects, they will be handled correctly.


File.open('message.txt') do|message|
  agent.post('http://example.com/upload/',
             { :message => message })
end

The final parameter to Mechanize#post is a hash of custom parameters, as with Mechanize#get.
