Python webscraping page which requires login

I am trying to automate a web data gathering process using Python. In my case, I need to pull the information from https://app.ixml.com.br/documentos/nfe page. However, before you go to this page, you need to log in at https://app.ixml.com/login. The code below should theoretically log into the site:
import re
from robobrowser import RoboBrowser
username = 'email'
password = 'password'
br = RoboBrowser()
br.open('https://app.ixml.com.br/login')
form = br.get_form()
form['email'] = username
form['senha'] = password
br.submit_form(form)
src = str(br.parsed())
However, by printing the src variable, I get the source code from the https://app.ixml.com.br/login page, ie before logging in. If I add the following lines at the end of the previous code
br.open('https://app.ixml.com.br/documentos/nfe')
src2 = str(br.parsed())
The src2 variable contains the source code of the page https://app.ixml.com.br/. I tried some variations, such as creating a new br object, but got the same result. How can I access the information at https://app.ixml.com.br/documentos/nfe?

If it is ok to have a webpage opening you can try to solve this using selenium. This package makes it possible to create a program that reacts just like a user would.
The following code would have you login:
from selenium import webdriver
browser = webdriver.Firefox()
browser.get("https://app.ixml.com.br/login")
browser.find_element_by_id("email").send_keys("abc#mail")
browser.find_element_by_id("senha").send_keys("abc")
browser.find_element_by_css_selector("button").click()

Shell script to download a lot of HTML files and store them statically with all CSS

I have posted on a science forum (roughly 290 questions) that I would like to get back by downloading them with all the associated answers.
The first issue is that I have to be logged on my personal space to have the list of all the messages. How to circumvent this first barrier to be able with a shell script or a single wget command to get back all URL and their content. Can I pass to wgeta login and a password to be logged and redirected to the appropriate URL obtaining the list of all messages?
Once this first issue will be solved, the second issue is that I have to start from 6 different menu pages that all contain the title and the link of the questions.
Moreover, concerning some of my questions, the answers and the discussions may be on multiple pages.
So I wonder if I could achieve this operation of global downloading knowing I would like to store them statically with local CSS stored also on my computer (to keep the same format into my browser when I consult them on my PC).
The URL of the first menu page of questions is (once I am logged on the website : that could be an issue also to download with wget if I am obliged to be connected).
An example of URL containing the list of messages, once I am logged, is:
https://forums.futura-sciences.com/search.php?searchid=22897684
The other pages (there all 6 or 7 pages of discussions title in total appering in the main menu page) have the format:
"https://forums.futura-sciences.com/search.php?searchid=22897684&pp=&page=2" (for page 2).
https://forums.futura-sciences.com/search.php?searchid=22897684&pp=&page=5
(for page 5)
One can see on each of these pages the title and the link of each of the discussions that I would like to download with also CSS (knowing each discussion may contain multiple pages also) :
for example the first page of discussion "https://forums.futura-sciences.com/archives/804364-demonstration-dilatation-temps.html"
has page 2: "https://forums.futura-sciences.com/archives/804364-demonstration-dilatation-temps-2.html"
and page 3: "https://forums.futura-sciences.com/archives/804364-demonstration-dilatation-temps-3.html"
Naively, I tried to do all this with only one command (with the example of URL on my personal space that I have taken at the beginning of post, i.e "https://forums.futura-sciences.com/search.php?searchid=22897684"):
wget -r --no-check-certificate --html-extension --convert-links "https://forums.futura-sciences.com/search.php?searchid=22897684"
but unfortunately, this command downloads all files, and even maybe not what I want, i.e my discussions.
I don't know what the approach to use: must I firstly store all URL in a file (with all sub-pages containing all answers and the global discussion for each of mu initial question)?
And after, I could do maybe a wget -i all_URL_questions.txt. How can I carry out this operation?
Update
My issue needs a script, I tried with Python the following things:
1)
import urllib, urllib2, cookielib
username = 'USERNAME'
password = 'PASSWORD'
cj = cookielib.CookieJar()
opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj))
login_data = urllib.urlencode({'username' : username, 'password' : password})
opener.open('https://forums.futura-sciences.com/login.php', login_data)
resp = opener.open('https://forums.futura-sciences.com/search.php?do=finduser&userid=253205&contenttype=vBForum_Post&showposts=1')
print resp.read()
But the page printed is not the page of my home into personal space.
2)
import requests
# Fill in your details here to be posted to the login form.
payload = {
'inUserName': 'USERNAME',
'inUserPass': 'PASSWORD'
}
# Use 'with' to ensure the session context is closed after use.
with requests.Session() as s:
p = s.post('https://forums.futura-sciences.com/login.php?do=login', data=payload)
# print the html returned or something more intelligent to see if it's a successful login page.
print p.text.encode('utf8')
# An authorised request.
r = s.get('https://forums.futura-sciences.com/search.php?do=finduser&userid=253205&contenttype=vBForum_Post&showposts=1')
print r.text.encode('utf8')
Here too, this doesn't work
3)
import requests
import bs4
site_url = 'https://forums.futura-sciences.com/login.php?do=login'
userid = 'USERNAME'
password = 'PASSWWORD'
file_url = 'https://forums.futura-sciences.com/search.php?do=finduser&userid=253205&contenttype=vBForum_Post&showposts=1'
o_file = 'abc.html'
# create session
s = requests.Session()
# GET request. This will generate cookie for you
s.get(site_url)
# login to site.
s.post(site_url, data={'vb_login_username': userid, 'vb_login_password': password})
# Next thing will be to visit URL for file you would like to download.
r = s.get(file_url)
# Download file
with open(o_file, 'wb') as output:
output.write(r.content)
print("requests:: File {o_file} downloaded successfully!")
# Close session once all work done
s.close()
Same thing, the content is wrong
4)
from selenium import webdriver
# To prevent download dialog
profile = webdriver.FirefoxProfile()
profile.set_preference('browser.download.folderList', 2) # custom location
profile.set_preference('browser.download.manager.showWhenStarting', False)
profile.set_preference('browser.download.dir', '/tmp')
profile.set_preference('browser.helperApps.neverAsk.saveToDisk', 'text/csv')
webdriver.get('https://forums.futura-sciences.com/')
webdriver.find_element_by_id('ID').send_keys('USERNAME')
webdriver.find_element_by_id ('ID').send_keys('PASSWORD')
webdriver.find_element_by_id('submit').click()
browser = webdriver.Firefox()
browser.get('https://forums.futura-sciences.com/search.php?do=finduser&userid=253205&contenttype=vBForum_Post&showposts=1')
Still not getting to log in with USERNAME and PASSSWORD and get content of homepage of personal space

The window is well opened, username filled but impossible to fill or submit the password and click on submit.
PS: the main issue could come from that password field has display:none property, So I can't simulate TAB operation to password field and pass it, once I have put the login.

It seems you're pretty knowledgeable already about scraping using the various methods. All that was missing were the correct field names in the post request.
I used the chrome dev tools (f12 - then go to networking tab). With this open if you login and quickly stop the browser window from redirecting, you'll be able to see the full request to login.php and look at the fields etc.
With that I was able to build this for you. It includes a nice dumping function for responses. To test my code works you can use your real password for positive case and the bad password line for negative case.
import requests
import json
s = requests.Session()
def dumpResponseData(r, fileName):
print(r.status_code)
print(json.dumps(dict(r.headers), indent=1))
cookieDict = s.cookies.get_dict()
print(json.dumps(cookieDict, indent=1))
outfile = open(fileName, mode="w")
outfile.write(r.text)
outfile.close()
username = "your-username"
password = "your-password"
# password = "bad password"
def step1():
data = dict()
data["do"] = "login"
data["vb_login_md5password"] = ""
data["vb_login_md5password_utf"] = ""
data["s"] = ""
data["securitytoken"] = "guest"
data["url"] = "/search.php?do=finduser&userid=1077817&contenttype=vBForum_Post&showposts=1"
data["vb_login_username"] = username
data["vb_login_password"] = password
p = s.post('https://forums.futura-sciences.com/login.php?do=login', data=data)
# Logged In?
if "vbseo_loggedin" in s.cookies.keys():
print("Logged In!")
else:
print("Login Failed :(")
if __name__ == "__main__":
step1()
I don't have any posts in my newly created Futura account so I can't really do any more testing for you - I don't want to spam their forum with garbage.
But I would probably start by doing a request of post search url and scrape the links using bs4.
Then you could probably just use wget -r for each link you've scraped.

#Researcher is correct on their advice when it comes to the requests library. You are not posting all of the request params that the browser would send. Overall, I think it will be difficult to get requests to pull everything when you factor in static content and client side javascript
Your selenium code from section 4 has a few mistakes in it:
# yours
webdriver.find_element_by_id('ID').send_keys('USERNAME')
webdriver.find_element_by_id ('ID').send_keys('PASSWORD')
webdriver.find_element_by_id('submit').click()
# should be
webdriver.find_element_by_id('vb_login_username').send_keys('USERNAME')
webdriver.find_element_by_id('vb_login_password').send_keys('PASSWORD')
webdriver.find_element_by_xpath("//input[#type='submit']").click()
You may need to fiddle with the xpath for the submit button.
Hint: You can debug along the way by taking a screenshots :
webdriver.find_element_by_id('vb_login_username').send_keys('USERNAME')
webdriver.find_element_by_id('vb_login_password').send_keys('PASSWORD')
webdriver.get_screenshot_as_file('before_submit.png')
webdriver.find_element_by_xpath("//input[#type='submit']").click()
webdriver.get_screenshot_as_file('after_submit.png')

Python - How to read content of web page without using url?

I am trying to make a program in Python to log in to gmail and read the inbox page. This is what I have tried using Selenium and urllib2 (I am new to these):
from requests import session
from selenium import webdriver
import getpass
import urllib2
def gmail_login(username, passw) :
with session() as c :
webpage = r'https://accounts.google.com/ServiceLogin?service=mail&passive=true&rm=false&continue=https://mail.google.com/mail/&ss=1&scc=1&ltmpl=default&ltmplcache=2&emr=1&osid=1#identifier'
driver = webdriver.Chrome('C:\Users\chromedriver_win32\chromedriver.exe')
driver.get(webpage)
driver.implicitly_wait(10)
driver.find_element_by_name('Email').send_keys(username)
driver.find_element_by_name('signIn').click() # Click 'Next' button after entry of email id.
driver.find_element_by_id('Passwd').send_keys(passw)
driver.find_element_by_id('signIn').click() # Click 'Sign In' button after entry of password.
url = driver.current_url
readPage(url)
def readPage(url):
print url
fName = "gmail_file.html"
response = urllib2.urlopen(url)
html = response.read()
f = open(fName,"w")
f.write(html)
f.close()
gmail_login('username', 'password')
I got the login part correct but I'm not able to read the inbox page.
In my code I'm basically reopening the inbox page using the url and then reading it and saving it in a html file. But in my html file all I get is the login page! I am guessing that directly opening an inbox page using its url is not allowed and is protected.
So I'm looking for a way to read the content of a web page (any, not only gmail) whose url is not required for the purpose. (The only way I know to read a web page is using urlopen() which requires the url.) Is there any function or library for this purpose ?

You can try out Python imaplib package, to read and manage all your mails using the imap protocol.
You can find a code example here

You could use Charlie Guo's gmail package. Once installed, you can use it like this:
import gmail
g = gmail.login("devansh_sharma#gmail.com", "password123")
emails = g.inbox().mail(unread=True)
for email in emails:
email.fetch()
header_from = email.headers['From']
subject = email.headers['Subject']
body = email.body
[... do something cool with your gmail...]
That's going to be much more reliable and simpler than screen scraping.

Having Trouble With Python Login Bot

I am currently trying to create a python bot using mechanize that scrapes my account for a school project however I am having trouble logging in to this website: https://marketwatch.com/login
import mechanize
loginurl = https://marketwatch.com/login
user = raw_input("enter user")
passcode = raw_input("enter passcode")
browser = mechanize.Browser()
browser.set_handle_robots(False)
browser.open(loginurl)
browser.select_form(nr=0)
browser.form["username"] = user
browser.form["password"] = passcode
browser.submit()
print(browser.title())
After I run the code it doesn't login, but instead it remains on the login page. Any possible solutions? Any help would be greatly appreciated!

As jm_____ said selenium is what you're looking for.
Selenium can be found here
Here is a login script utilizing selenium. Ill leave the scraping of whichever page comes after the login to you.
import selenium
from selenium import webdriver
browser = webdriver.Firefox()
browser.get('http://marketwatch.com/login')
username = browser.find_element_by_name("username")
password = browser.find_element_by_name("password")
submit = browser.find_element_by_id("submitButton")
username.send_keys("username")
password.send_keys("password")
submit.click()

python urllib post question

im making some simple python post script but it not working well.
there is 2 part to have to login.
first login is using 'http://mybuddy.buddybuddy.co.kr/userinfo/UserInfo.asp' this one.
and second login is using 'http://user.buddybuddy.co.kr/usercheck/UserCheckPWExec.asp'
i can login first login page, but i couldn't login second page website.
and return some error 'illegal access' such like .
i heard this is related with some cooke but i don't know how to implement to resolve this problem.
if anyone can help me much appreciated!! Thanks!
import re,sys,os,mechanize,urllib,time
import datetime,socket
params = urllib.urlencode({'ID':'ph896011', 'PWD':'pk1089' })
rq = mechanize.Request("http://mybuddy.buddybuddy.co.kr/userinfo/UserInfo.asp", params)
rs = mechanize.urlopen(rq)
data = rs.read()
logged_fail = r';history.back();</script>' in data
if not logged_fail:
print 'login success'
try:

print data
except:
print 'error'

You can't use selenium? IMHO it's better do automation with this.
For install utilize:
pip install selenium
A example:
from selenium import webdriver
browser = webdriver.Firefox()
# open site
browser.get('http://google.com.br')
# get page source
browser.page_source
A login example:
# different methods to get a html item
form = browser.find_element_by_tag_name('form')
username = browser.find_element_by_id('input_username')
password = browser.find_element_by_css_selector('input[type=password]')
username.send_keys('myUser')
password.send_keys('myPass')
form.submit()
