Hi. I try to to make a python interaction with the form on: http://propka.ki.ku.dk/ I just try to set: version='v3.1' and PDBID='4AKE'
After the click and sending the form it stops. It should automatically refresh. Here is my code: import mechanize, sys, time, os url = "http://propka.ki.ku.dk/"; version = "v3.1" PDBID = "4AKE" verbose = 'yes' server_wait = 1.0 br = mechanize.Browser() br.addheaders = [('User-agent', 'pythonMechanizeClient')] ### The things was added according to: http://stockrt.github.com/p/emulating-a-browser-in-python-with-mechanize/ ### Dont know what they do. br.set_handle_equiv(True) br.set_handle_redirect(True) br.set_handle_referer(True) br.set_handle_robots(False) br.set_handle_refresh(mechanize._http.HTTPRefreshProcessor(), max_time=1) # Turn on debugging messages br.set_debug_http(True) #br.set_debug_redirects(True) #br.set_debug_responses(True) openpage = br.open(url) readpage = openpage.read() if verbose == 'yes': print br.title(); print br.geturl() #print readpage # To get available forms forms = [f.name for f in br.forms()] if verbose == 'yes': print forms ## Select first form br.select_form(name=forms[0]) ## Print the parameters of the 'version' RadioControl button and current value if verbose == 'yes': print br.find_control(name='version'); print br.find_control(name='version').value ## Change the parameters of the 'version' radio button and then reprint the new value br.form['version'] = [version] if verbose == 'yes': print br.find_control(name='version').value# ## Print the parameters of the 'PDBID' TextControl button and current value if verbose == 'yes': print br.find_control(name='PDBID'); print br.find_control(name='PDBID').value ## Change the parameters of the 'PDBID' TextControl and then reprint the new value br.form["PDBID"] = PDBID if verbose == 'yes': print br.find_control(name='PDBID').value ## Now reprint the current selected form, so we see that we have the right values. if verbose == 'yes': print br.form ## Two ways of submitting is tested #br.submit() req = br.click(type="submit", nr=0) ### Have to pass by a mechanize exception. Thats the reason for the why True ### The error was due to: #br.open(req) ##### mechanize._response.httperror_seek_wrapper: HTTP Error refresh: The HTTP server returned a redirect error that would lead to an infinite loop. ##### The last 30x error message was: ##### OK while True: try: br.open(req) break ### If there is raised an exception, we make a break. except: print("Waiting %s seconds for server"%server_wait) time.sleep(server_wait) break print br.geturl() print br.title() print br.response().read() ## Looking at some results in link format for l in br.links(): print l #for l in br.links(url_regex='stockrt'): # print l * It returns:* <HTML> <HEAD> <TITLE>PROPKA Progress</TITLE> <link rel="stylesheet" href="http://propka.ki.ku.dk/baker.css"; type="text/css"> <meta http-equiv="Refresh" content="1; url=/pka/temp-4AKE.html"> <META HTTP-EQUIV="expires" CONTENT="Wed, 09 Aug 2000 08:21:57 GMT"></HEAD> <BODY> <H2>PROPKA Progress</H2><P> The PROPKA server is generating your results - this page will automatically refresh every 1 seconds.<P> Thank you for your patience!<P> Server Progress:<P> <blockquote> <font size=2>Elapsed Time:</font> <code>19.00 seconds</code><BR> </blockquote> Server Information:<P> <blockquote> <font size=2>Server load:</font> <code>1.72 (1min) 0.86 (5min) 0.41 (15min)</code><BR> <font size=2>Server time:</font> <code>Tue Aug 9 15:33:56 2011</code><BR> </blockquote> </BODY></HTML> *And it should be send forward to a result page afterwards. *I think it is because I got exception error. ##### mechanize._response.httperror_seek_wrapper: HTTP Error refresh: The HTTP server returned a redirect error that would lead to an infinite loop. ##### The last 30x error message was: ##### OK and I stop after this exception error.
