我无法通过提交表单进行登录。错误是关于： ValueError：未知的POST表单编码类型'application / x-www-form-encoded'
这是我的尝试：
import mechanize
import cookielib
browser = mechanize.Browser()
# Cookie Jar
cookiejar = cookielib.LWPCookieJar()
browser.set_cookiejar(cookiejar)
# Browser options
browser.set_handle_equiv(True)
#browser.set_handle_gzip(True)
browser.set_handle_redirect(True)
browser.set_handle_referer(True)
browser.set_handle_robots(False)
# Follows refresh 0 but not hangs on refresh > 0
browser.set_handle_refresh(mechanize._http.HTTPRefreshProcessor(), max_time=1)
# Want debugging messages?
browser.set_debug_http(True)
browser.set_debug_redirects(True)
browser.set_debug_responses(True)
# User-Agent (this is cheating, ok?)
browser.addheaders = [('User-agent', 'Mozilla/5.0 (Windows NT 6.1; rv:29.0) Gecko/20100101 Firefox/29.0')]
response = browser.open("https://usms.upc.biz/arsys/shared/login.jsp")
# loginForm
browser.form = list(browser.forms())[0]
user_control = browser.form.find_control("username")
if user_control.type == "text":
user_control.value = "SNIP!"
passwd_control = browser.form.find_control("pwd")
if passwd_control.type == "password":
passwd_control.value = "SNIP!"
# browser.method = "POST"
response = browser.submit()
print response.read()
我得到的痕迹是：
