I am using python request library to access the soap requests. And it was working fine. As there is change in our domain structure. I could not access the url, it always prompting me to enter the credentials.
I am using below code to access the url earlier using requests.
program_list_response = requests.get(program_list_path,
data=self.body, headers=self.headers)
How to pass the authentication in background using requests?
You can use the Authentication feature for that in order to provide the credentials for the link that you want to access.
For an eg:
You can pass the username and password by using the below format:
requests.get('https://website.com/user', auth=('user', 'pass'))
For more details I would recommend the official docs.
For handling the Windows authentication then I would recommend the Requests-NTLM.
For eg:
import requests
from requests_ntlm import HttpNtlmAuth
requests.get("http://ntlm_protected_site.com",auth=HttpNtlmAuth('domain\\username','password'))

I have to scrape an internal web page of my organization. If I use Beautiful soap I get
"Unauthorized access"
I don't want to put my username/password in the source code because it will be shared across collegues.
If I open the same web url using Firefox It doesn't not ask me to login, the only problem is when I make the same request using python script.
Is there a way to share the same session used by firefox with a python script?
I think my authentication is with my PC because if I log off deleting all cookies When i re-enter I because logged in automatically. Do you know why with my python script this doesn’t not happen?
When you use the browser to login to your organization, you provide your credentials and the server returns a cookie tied to your organization's domain. This cookie has an expiration and allows to use navigate your organization's site without having to login as long as the cookie is valid.
You can read about cookies here:
https://en.wikipedia.org/wiki/HTTP_cookie
Your website scraper does not need to store your credentials. First delete the cookies then, using your browser's developer tools, you can (look at the network tab):
Figure out if your organization uses a separate auth end point
If it's not evident, then you might ask the IT department
Use the auth endpoint to get a cookie using credentials passed in
See how this cookie is used by the system (look at the HTTP request/response headers)
Use this cookie to scrape the website
Share your code freely - if someone needs to scrape the website then they can either pass in their credentials, or use a curl command to get/set a valid cookie header
1) After authenticating in your Firefox browser, make sure to get the cookie key/value.
2) Use that data in the code below :
from bs4 import BeautifulSoup
import requests
browser_cookies = {'your_cookie_key':'your_cookie_value'}
s = requests.Session()
r = s.get(your_url, cookies=browser_cookies)
bsoup = BeautifulSoup(r.text, 'lxml')
The requests.Session() is for persistence.
One more tips, you could also call your script like that :
python3 /path/to/script/script.py cookies_key cookies_value
Then, get the two values with sys module. The code will be :
import sys
browser_cookies = {sys.argv[1]:sys.argv[2]}
I can get html of a web site using lxml module if authentication is not required. However, when it required, how do I input 'User Name' and 'Password' using python?
It very much depends on the method of authentication used. If it's HTTP Basic Auth, then you should be able to pass those headers along with the request. If it's using a web page-based login, you'll need to automate that request and pass back the cookies or whatever session token is used with the next request.
I'm interested in using Python to retrieve a file that exists at an HTTPS url.
I have credentials for the site, and when I access it in my browser I'm able to download the file. How do I use those credentials in my Python script to do the same thing?
So far I have:
import urllib.request
response = urllib.request.urlopen('https:// (some url with an XML file)')
html = response.read()
html.write('C:/Users/mhurley/Portable_Python/notebooks/XMLOut.xml')
This code works for non-secured pages, but (understandably) returns 401:Unauthorized for the https address. I don't understand how urllib handles credentials, and the docs aren't as helpful as I'd like.
I am using google api to fetch audit logs. The code work fine and generate a URL .
I paste this URL on my browser and it ask for g-mail login authorization.
After authorizing it will redirect me to new URL.
I tried doing this automatically with python code but couldn't able to authenticate before getting final/redirect URL.
I tried following code but no success:
import urllib2, base64
request = urllib2.Request("http://api.foursquare.com/v1/user")
base64string = base64.encodestring('%s:%s' % (username, password)).replace('\n', '')
request.add_header("Authorization", "Basic %s" % base64string)
result = urllib2.urlopen(request)
How is this possible to authenticate and redirect to final URL using python?
I would seriously consider using python's requests library for accessing the API. Basic authentication is this easy with requests:
requests.get('http://api.foursquare.com/v1/user', auth=('username', 'password'))
It will automatically follow any redirects. I doubt you need to follow redirects when using basic authentication with the foursquare api, but requests will do this too if you need it.
I have the following site in SharePoint 2013 in my local VM:
http://win-5a8pp4v402g/sharepoint_test/site_1/
When I access this from the browser, it prompts me for the username and password and then works fine. However I am trying to do the same using the REST API in Python. I am using the requests library, and this is what I have done:
import requests
from requests.auth import HTTPBasicAuth
USERNAME = "Administrator"
PASSWORD = "password"
response = requests.get("http://win-5a8pp4v402g/sharepoint_test/site_1/", auth=HTTPBasicAuth(USERNAME, PASSWORD))
print response.status_code
However I get a 401. I dont understand. What am I missing?
Note: I followed this article http://tech.bool.se/using-python-to-request-data-from-sharepoint-via-rest/
It's possible that your SharePoint site uses a different authentication scheme. You can check this by inspecting the network traffic in Firebug or the Chrome Developer Tools.
Luckily, the requests library supports many authentication options: http://docs.python-requests.org/en/latest/user/authentication/
Fore example, one of the networks I needed to access uses NTLM authentication. After installing the requests-ntml plugin, I was able to access the site using code similar to this:
import requests
from requests_ntlm import HttpNtlmAuth
requests.get("http://sharepoint-site.com", auth=HttpNtlmAuth('DOMAIN\\USERNAME','PASSWORD'))
Here is an examples of SharePoint 2016 REST API call from Python to create a site.
import requests,json,urllib
from requests_ntlm import HttpNtlmAuth
root_url = "https://sharepoint.mycompany.com"
headers = {'accept': "application/json;odata=verbose","content-type": "application/json;odata=verbose"}
##"DOMAIN\username",password
auth = HttpNtlmAuth("MYCOMPANY"+"\\"+"UserName",'Password')
def getToken():
contextinfo_api = root_url+"/_api/contextinfo"
response = requests.post(contextinfo_api, auth=auth,headers=headers)
response = json.loads(response.text)
digest_value = response['d']['GetContextWebInformation']['FormDigestValue']
return digest_value
def createSite(title,url,desc):
create_api = root_url+"/_api/web/webinfos/add"
payload = {'parameters': {
'__metadata': {'type': 'SP.WebInfoCreationInformation' },
'Url': url,
'Title': title,
'Description': desc,
'Language':1033,
'WebTemplate':'STS#0',
'UseUniquePermissions':True}
}
response = requests.post(create_api, auth=auth,headers=headers,data=json.dumps(payload))
return json.loads(response.text)
headers['X-RequestDigest']=getToken()
print createSite("Human Resources","hr","Sample Description")
You can also use Office365-REST-Python-Client ("Office 365 & Microsoft Graph Library for Python") or sharepoint ("Module and command-line utility to get data out of SharePoint")
A 401 response is an authentication error...
That leaves one of your three variables as incorrect: url, user, pass. Requests Authentication Docs
Your url looks incomplete.
