can'；t使用python mechanize从网站访问表单

我试图访问特定网站中的表单，下面是表单的HTML代码

<form name="calendarForm" method="post" action="/ibook/loginSelection.do"><div><input name="org.apache.struts.taglib.html.TOKEN" value="489be5fa2613d2f762b6389c3dd5ea3f" type="hidden"></div>
            <table border="0" cellpadding="0" cellspacing="0">
                <tbody><tr><td>Please select one of the following services: 
                </td></tr><tr><td>
                    <select name="apptDetails.apptType" onchange="javascript:document.forms[0].submit()" class="txtFill_singleLine">    <option value="CS">--Citizen--</option>
<option value="CSCA">Citizenship Application Interview</option>
<option value="CSCR">Citizenship Registration</option>
<option value="CSIC">Collection of Identity Card</option>
<option value="CSPC">Collection of Passport</option>
<option value="CSXX"></option>
<option value="PR">--Permanent Resident--</option>
<option value="PRAP">Apply for PR</option>
<option value="PRCF">Completion of Formalities for Successful     Applicants</option>
<option value="PRAR">Apply for REP (Renewal) / CI</option>
<option value="PRIC">Collection of IC (New SPR)</option>
<option value="PRNN">Collection of IC (SPR)</option>
<option value="PRTR">Apply for REP (Transfer)</option>
<option value="CSXX"></option>
<option value="VS">--Visitor--</option>
<option value="VSEI">Application for e-IACS</option>
<option value="VSLA">Apply for Long Term Visit Pass</option>
<option value="VSLT">Completion of Long Term Visit Pass Formalities</option>
<option value="VSSP">Completion of Student's Pass Formalities</option>
<option value="VSST">Report to VSC Appointment</option>
<option value="VSVP">Collection of Long Term Pass Card</option></select>
                </td></tr>
           </tbody></table>
         </form>

这是我的代码，我使用了许多示例中的一个来实现我的目的，但它无法通过表单未找到错误

import cookielib 
import urllib2 
import mechanize 

# Browser 
br = mechanize.Browser() 

# Enable cookie support for urllib2 
cookiejar = cookielib.LWPCookieJar() 
br.set_cookiejar( cookiejar ) 

# Broser options 
br.set_handle_equiv( True ) 
br.set_handle_gzip( 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 ) 

br.addheaders = [ ( 'User-agent', 'Mozilla/5.0 (Windows NT 6.1; WOW64; rv:35.0) Gecko/20100101 Firefox/35.0' ),('Host','eappointment.ica.gov.sg'),('Accept','text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8') ] 

# authenticate 
br.open('https://eappointment.ica.gov.sg/ibook/index.do')

print "forms"
br.select_form(name="calendarForm")
print "forms"

# these two come from the code you posted
# where you would normally put in your username and password
br[ "apptDetails.apptType" ] = 'PRAP'
res = br.submit() 
br.close()
print "Success!\n"

要提交

日历表单

，您应该使用

机械化

访问不同的URL：

br.open('https://eappointment.ica.gov.sg/ibook/gethome.do')
br.select_form(name="calendarForm")

br.open('https://eappointment.ica.gov.sg/ibook/gethome.do')
br.select_form(name="calendarForm")
