How to fill and submit a form using python

I am filling a form of a web page with the help of mechanize module but I am getting error when I run my code.
I just want to fill the form and submit it successfully.
My attempt :
code snippet from this stack answer
import re
from mechanize import Browser
username="Bob"
password="admin"
br = Browser()
# Ignore robots.txt
br.set_handle_robots( False )
# Google demands a user-agent that isn't a robot
br.addheaders = [('User-agent', 'Firefox')]
br.open("https://fb.vivoliker.com/app/fb/token")
br.select_form(name="order")
br["u"] = [username]
br["p"]=[password]
response = br.submit()
Output :
Error (FormNotFoundError)
but what should I enter the name in br.select_form() because when I see source code of web page their is no name attribute set to that form.
Html source code of form from web page
<div class="container">
<form ls-form="fb-init">
<input type="hidden" name="machine_id">
<div class="form-group row">
<input id="u" type="text" class="form-control" placeholder="Facebook Username / Id / Email / Mobile Number" required="required">
</div>
<div class="form-group row">
<input id="p" type="password" class="form-control" placeholder="Facebook Password" required="required">
</div>
<div class="form-group row mt-3">
<button type="button" id='generating' class="btn btn-primary btn-block" onclick="if (!window.__cfRLUnblockHandlers) return false; get()" data-cf-modified-4e9e40fa9e78b45594c87eaa-="">Get Access Token</button>
</div>
<div ls-form="event"></div>
</form>
Expected output :
My form should be submit with the values that I given.

I believe the form you want to select is ls-form=fb-init
However, since mechanize module requires replacing hyphens with underscores to convert HTML attrs to keyword arguments, you would want to write it like this:
br.select_form(ls_form='fb-init')
To clarify, the correct form to select is not named 'order', the form is named 'fb-init' and it is a ls-form (written as 'ls_form' with underscore). So with the change, it should be like this:
import re
from mechanize import Browser
username="Bob"
password="admin"
br = Browser()
# Ignore robots.txt
br.set_handle_robots( False )
# Google demands a user-agent that isn't a robot
br.addheaders = [('User-agent', 'Firefox')]
br.open("https://fb.vivoliker.com/app/fb/token")
br.select_form(ls_form='fb-init')
And then continue from there.

Bootstrap 4 input field not sending value to server (python, flask, GAE)

I can't get an input field in a form to send a value to the server. (I'm using flask + python on Google App Engine).
Please excuse me if this is a rookie question...
Part of my html template file:
<form class="form-inline" action="/rm_list" method="POST">
<div class="row" >
<div class="col-span-6">
<fieldset>
<input class="form-control form-control-lg" type="text" name="searchtext" placeholder="Product...">
<input name="text1">
<button class="btn btn-primary" type="submit"><i class="material-icons w3-text-black" >search</i></button>
</div>
...
...
some radio buttons
So I dumped the POST data to the terminal to debug:
my_data = request.form
for key in my_data:
print ('form key '+key+" "+my_data[key])
After trying different solutions, I found that the culprit is the type="text" attribute.
I could see the value of the simple text1 input, but the value from the searchtext input just wasn't in the received data :-(
If I remove "type="text" as follows:
<input class="form-control form-control-lg" name="searchtext" Placeholder="Product...">
then the searchtext field is received Ok by the server.
Any ideas what I'm doing wrong?
Thanks!

It seems to me that your field is simply missing the value attribute. – Anonymous

Get Data from Bootstrap Modal via POST request

I need to get data from a bootstrap modal input. I'am using the following code :
#app.route('/rejets_modeles', methods=("POST","GET"))
def rejets_modeles():
{code}
if request.method == 'POST':
uname = request.form['uname']
print("----")
print(uname)
return render_template ('rejets_modeles.html', tables=[df.to_html(table_id = 'rejets_modeles')], titles=df.columns.values, header="true")
And here is my HTML code
<form action="POST">
<div class="modal-body-modifs">
<p>Gestion du rejet : </p>
<label><b>NOM</b></label>
<input type="text" name="uname"></br>
<label><b>PRENOM</b></label>
<input type="text" name="uprenom"></br>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
<button type="submit" class="btn btn-default" data-dismiss="modal"> OK</button>
</div>
</form>
I don't even have the ("---") printed, that means that my 'POST' request isnt' interpreted. How can I fix that ? Thank you

It has to be method instead of action
<form method="POST">
In action you can set url to which it has to send form data - ie.
<form method="POST" action="/rejets_modeles">
but if you want to send to the same url then you don't have to set it.

Solved. The problem was data-dismiss="modal" in my input tag. If you delete this the modal will close and the form will be sent via POST request.

Python: Trying to loggin with requests and perform a HTTP request

I am trying to loggin to my account using the following python code without success. The login-process is in two steps on two pages. First enter login, second enter password. I am using Python3:
from bs4 import BeautifulSoup
import requests, lxml.html
with requests.Session() as s:
#First login page
login = s.get('https://accounts.ft.com/login')
login_html = lxml.html.fromstring(login.text)
#getting the form inputs
hidden_inputs = login_html.xpath(r'//form//input')
form = {x.name: x.value for x in hidden_inputs}
#filling inputs with email
form['email'] = 'me#mail.com'
response = s.post('https://accounts.ft.com/login', data=form)
# Receive reponse 200
#Second login page
login_html = lxml.html.fromstring(response.text)
#getting inputs
hidden_inputs = login_html.xpath(r'//form//input')
form = {x.name: x.value for x in hidden_inputs}
#filling inputs with email and password
form['email'] = 'me#mail.com'
form['password'] = 'p****word'
response = s.post('https://accounts.ft.com/login', data=form)
#Receive reponse 200
#Trying to read an article being loggedIn
page = s.get('https://www.ft.com/content/173695cc-1a98-11e7-a266-12672483791a')
soup = BeautifulSoup(page.content, 'html.parser')
print(soup.prettify())
# data-next-is-logged-in="false" => Please Register to read this page...
Here is what the Form looks like:
<div class="js-container" data-component="two-step-login-form" id="content">
<div class="lgn-box">
<form action="/login/submitEmail" class="js-email-lookup-form" data-test-id="enter-email-form" method="POST" name="enter-email-form" novalidate="">
<input name="location" type="hidden" value="" />
<input name="continueUrl" type="hidden" value="" />
<input name="readerId" type="hidden" value="" />
<input name="loginUrl" type="hidden" value="/login" />
<div class="lgn-box__title">
<h1 class="lgn-heading--alpha">
Sign in
</h1>
</div>
<div class="o-forms-group">
<label class="o-forms-label" for="email">
Email address
</label>
<input autocomplete="off" autofocus="" class="o-forms-text js-email" id="email" maxlength="64" name="email" required="" type="email">
<input id="password" name="password" style="display:none" type="password">
<label for="password">
</label>
</input>
</input>
</div>
<div class="o-forms-group">
<button class="o-buttons o-buttons--standout o-buttons--big" name="Next" type="submit">
Next
</button>
</div>
</form>
</div>
Here is what my data passed to POST looks like:
form
{'password': 'p****word', 'continueUrl': '', 'loginUrl': '/login', 'email': 'me#mail.com', 'readerId': '', 'location': ''}
The POST request returns for both 1st and 2nd loggin page a 200 response. But it seems that I am still not logged in.
I have tried using http://accounts.ft.com/sso/redirects?email=me#mail.com as a URL for POST request, returning a 405 Bad Request error
I am not sure that I am actually not logged in, bud I have no idea how to monitor that.
Is it possible that the website prevents me from logging-in if not in a web-browser?

Try using selenium to simulate the web browser as it appears that FT blocks automated access.
Alternatively you can see if a site has been archived with something like archive.is (which will pull most sites into a more machine friendly setup).
Finally, there is both a datamining API and a headline API that the FT offers at their developer page

Python 3 script for logging into a website using the Requests module

I'm trying to write some Python (3.3.2) code to log in to a website using the Requests module. Here is the form section of the login page:
<form method="post" action="https://www.ibvpn.com/billing/dologin.php" name="frmlogin">
<input type="hidden" name="token" value="236647d2da7c8408ceb78178ba03876ea1f2b687" />
<div class="logincontainer">
<fieldset>
<div class="clearfix">
<label for="username">Email Address:</label>
<div class="input">
<input class="xlarge" name="username" id="username" type="text" />
</div>
</div>
<div class="clearfix">
<label for="password">Password:</label>
<div class="input">
<input class="xlarge" name="password" id="password" type="password"/>
</div>
</div>
<div align="center">
<p>
<input type="checkbox" name="rememberme" /> Remember Me
</p>
<p>Request a Password Reset</p>
</div>
</fieldset>
</div>
<div class="actions">
<input type="submit" class="btn primary" value="Login" />
</div>
</form>
Here is my code, trying to deal with hidden input:
import requests
from bs4 import BeautifulSoup
url = 'https://www.ibvpn.com/billing/clientarea.php'
body = {'username':'my email address','password':'my password'}
s = requests.Session()
loginPage = s.get(url)
soup = BeautifulSoup(loginPage.text)
hiddenInputs = soup.findAll(name = 'input', type = 'hidden')
for hidden in hiddenInputs:
name = hidden['name']
value = hidden['value']
body[name] = value
r = s.post(url, data = body)
This just returns the login page. If I post my login data to the URL in the 'action' field, I get a 404 error.
I've seen other posts on StackExchange where automatic cookie handling doesn't seem to work, so I've also tried dealing with the cookies manually using:
cookies = dict(loginPage.cookies)
r = s.post(url, data = body, cookies = cookies)
But this also just returns the login page.
I don't know if this is related to the problem, but after I've run either variant of the code above, entering r.cookies returns <<class 'requests.cookies.RequestsCookieJar'>[]>
If anyone has any suggestions, I'd love to hear them.

You are loading the wrong URL. The form has an action attribute:
<form method="post" action="https://www.ibvpn.com/billing/dologin.php" name="frmlogin">
so you must post your login information to:
https://www.ibvpn.com/billing/dologin.php
instead of posting back to the login page. POST to soup.form['action'] instead:
r = s.post(soup.form['action'], data=body)
Your code is handling cookies just fine; I can see that s.cookies holds a cookie after requesting the login form, for example.
If this still doesn't work (a 404 is returned), then the server is using additional techniques to detect scripts vs. real browsers. Usually this is done by parsing the request headers. Look at your browser headers and replicate those. It may just be the User-Agent header that they parse, but Accept-* headers and Referrer can also play a role.
