Login and upload file using Python 'requests'

Question

I need to login and upload a file . The problem I am facing is, login page is different from uploading page. If I have to do it manually, I'll login (login.php) to the site and then navigate to the upload page (uploader.php) to upload the file. This what I have written:

import requests

url1='http://www.abc.com/login.php'
r = requests.post(url1, auth=('uname', 'pword'))
print r.status_code //msg:'200'

payload = {'upload':open('./tmp.txt')}
url2='http://www.abc.com/uploader.php'
r = requests.post(url2, data=payload)
print r.text //msg: "you must first login to upload the file"

My code is obviously not working as expected. Login part is working correctly but not uploading part. Please how can I accomplish my goal.

UPDATE:

To give more insight into my question, I am giving login.php and uploader.php file details:

login.php

<form method="POST" action="login.php" class="login">
<input type="text" name="username"></input>
<input type="password" name="password"></input>        
<input type="submit" value="Login"></input>

uploader.php

<form action='uploader.php' method='POST' id='form' class='upload' enctype="multipart/form-data" >
<input type='file' name='upload' id='file'></input>
<input type='button' value='Analyze' name='button' onclick='javascript: checkuploadform(false)'>

Hey, you're doing a get requests to login.php when it should be post, according to above html. — svineet

Make a session and then use that session to do your requests -

sessionObj = requests.session()
sessionOj.get(...) # Do whatever ...

A session persists your cookies for future requests.
And use post parameters for username,password as the parameters are required to login in login.php , not auth username password.
Also use files parameter to upload files. So the final code is -

import requests

sessionObj = requests.session()
url1='http://www.abc.com/login.php'
r = sessionObj.post(url1, params={'username':'usernamehere' , 'password':'password here'})
print r.status_code //msg:'200'


filehandle = open('./tmp.txt')
url2='http://www.abc.com/uploader.php'
r = sessionObj.post(url2, data={},files = {'upload':filehandle})
print r.text
