Python Submit form

Question

I would like to fill in and submit a form on a web page using python.

This form:

<form method="POST" id="login" action="site/enter.php" >
  <input type="text" placeholder="Login" name="login" class="login" tabindex="1">
  <input type="password" placeholder="Password" name="psw" class="password" tabindex="2">
  <input type="submit" class="btn_auth" value="" title="Enter" tabindex="3">
</form>

But can't do it. I place login and pass, but can't emulate submit button.

What? What kind of web-framework are you using, if any? What are you having troubles with? We need waaaay more info. — pcalcao

Please post the non-working code, otherwise this question is way too vague. — Steven Rumbalski

It's much easier to use selenium's Webdriver to drive webpages than to use something like mechanize. Especially if the page is dynamically created.

You'll need to install selenium. pip install selenium should work. You'll also need a version of Firefox installed.

from selenium import webdriver

browser = webdriver.Firefox()
browser.implicitly_wait(5)
browser.get('http://some_url.com')
browser.find_element_by_id('login').send_keys('your_login') 
browser.find_element_by_name('pws').send_keys('your_password')
browser.find_element_by_class_name('btn_auth').click() 

print browser.page_source
browser.close()

unless the page uses JavaScript. It is an overkill

Well, since so much of the web is now rendered with JS I find it's best to go there first. What part didn't work Ur Riv?

It just open Chrome and don't do anything

So there is no stacktrace? I noticed an extra space in my code which I just removed? You aren't just blindly copying this are you?

@aychedee - I'm getting a message 'WebDriver' object has no attribute 'implicitly'. What is that line supposed to do? Does leaving it off change how this works?
