Good evening everyone I had to implement the twilio module in my django project and it works well, the problem is that it does not allow you to send sms to phone numbers other than mine
I think sample code is like the following. You need set the two environment variables TWILIO_ACCOUNT_SID and TWILIO_AUTH_TOKEN.
import os
from twilio.rest import Client
account_sid = os.environ['TWILIO_ACCOUNT_SID']
auth_token = os.environ['TWILIO_AUTH_TOKEN']
client = Client(account_sid, auth_token)
message = client.messages.create(
body="your message",
from_='+15017122661',
to='+15558675310'
)
print(message.sid)

I am making an app in flutter which uses Google sign-in. I also have a Django backend linked to the app and I want to verify the user in the Django backend. I found many solutions on the internet but none is working. Probably I am messing up somewhere.
I tried using python-jose for verification and here is the code:
from jose import jwt
import urllib.request, json
token = '<token recieved using await user.getIdToken in flutter>'
target_audience = "<tried projectid/appid>"
certificate_url = 'https://www.googleapis.com/robot/v1/metadata/x509/securetoken#system.gserviceaccount.com'
response = urllib.request.urlopen(certificate_url)
certs = response.read()
certs = json.loads(certs)
print(certs)
user = jwt.decode(token, certs, algorithms='RS256',
audience=target_audience)
I also tried oauth2client, the code is here:
from oauth2client import crypt
import urllib.request, json
certificate_url = 'https://www.googleapis.com/robot/v1/metadata/x509/securetoken#system.gserviceaccount.com'
target_audience = 'tried projectid/appid'
response = urllib.request.urlopen(certificate_url)
certs = response.read()
certs = json.loads(certs)
print(certs)
crypt.MAX_TOKEN_LIFETIME_SECS = 30 * 86400
idtoken = 'token received from await user.getIdToken()'
crypt.verify_signed_jwt_with_certs(idtoken, certs, target_audience)
I also tried firebase_admin for python:
import firebase_admin
from firebase_admin import credentials
from firebase_admin import auth
cred = credentials.Certificate('<firebase service accounts private key>')
default_app = firebase_admin.initialize_app(cred)
token = 'token from flutter'
verifyied =auth.verify_id_token(id_token=token)
Just to check whether the firebase_admin library itself is working or not, I passed the userid to server from the app and tried deleting the user using firebase_admin and I could do that. But for some reason I am unable to verify the token.
Thanks for the help.
I have also faced the same issue.
Case:
Initially: I was printing auth token in vscode console and was verifying in terminal.
It gave me the error: token length cannot be 1 more than % 4.
I tried verifying the token from jwt.io and it was seemingly correct.
Actual Reason for the issue:
The console output of vscode (in my case windows 7 and 64 bit). Is limited to 1064 characters for a line.
Although the actual length of token is supposed to be 1170 characters.
Workaround Solution:
Print the substring in the vscode console and the join them in python shell to verify.
Answering my own question. The problem was that my server was not actually deployed, so, I was copying the token printed in vscode console when the user logs in and pasting it into the python code and trying to verify the token. Turns out it doesn't work that way.
I hosted my Django app and passed the token in a post request and then tried to verify the token and it worked.

I would like to implement twilio video API in my Django project but i didn't really understand the documentation. I managed to create a room following this example:
from twilio.rest import Client
api_key_sid = "SKXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"
api_key_secret = "your_api_key_secret"
client = Client(api_key_sid, api_key_secret)
room = client.video.rooms.create(unique_name='DailyStandup')
print(room.sid)
What should I do after that? How can I access the room and start the chat?
I am trying to scrape using proxy from proxymesh.com
I am currently using the following code,
It opens Chrome and creates a javascript alert to input username and password.
I am currently doing is manually everytime I run a new instance of the script.
If someone could please help in automating it.
There could be 2 ways to do it,
Either somehow pass the username and password through Chrome Options
OR
Somehow make webdriver switch to javascript alert and enter the username and password there.
Here is my code so far,
from selenium import webdriver
chrome_option = webdriver.ChromeOptions()
chrome_option.add_argument("--proxy-server=http://us.proxymesh.com:31280")
b = webdriver.Chrome('chromedriver.exe',
chrome_options=chrome_option)
"Do Something"
Thanks in advance
This is what has worked for me using Chrome and proxy authentication. I don't have a proxymesh account, so you'll have to verify if it works or not yourself:
from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
proxy = {'address': 'us.proxymesh.com:31280',
'usernmae': 'johnsmith123',
'password': 'iliketurtles'}
capabilities = dict(DesiredCapabilities.CHROME)
capabilities['proxy'] = {'proxyType': 'MANUAL',
'httpProxy': proxy['address'],
'ftpProxy': proxy['address'],
'sslProxy': proxy['address'],
'noProxy': '',
'class': "org.openqa.selenium.Proxy",
'autodetect': False}
capabilities['proxy']['socksUsername'] = proxy['username']
capabilities['proxy']['socksPassword'] = proxy['password']
driver = webdriver.Chrome(executable_path=[path to your chromedriver], desired_capabilities=capabilities)
I have two servers running django. I'll call one server my "logging" server and another my "client" server. The client server wants to log a message with the logging server by passing over a username, password, and message over the internet. With my current implementation I'm hitting an error when trying to decrypt the encrypted message, username, and password that was sent over the wire. It looks like I should be trying to decrypt a "byte string" according to the pycrypto documentation, but I can't seem to create a byte string correctly since I haven't been able to get around this problem. Also, it feels like my implementation is taking me down a rabbit hole of security vulnerabilities and codec confusion. Is there a package that I should look at which already implements this type of functionality? If so what would that implementation look like?
client:
from Crypto.Hash import MD5
from Crypto.PublicKey import RSA
from base64 import b64decode

#I realize recreating the hash everytime is slow. I just included it here for simplicity.

logger_public_signature_hash = MD5.new(logger_public_signature_message).digest()
client_private_key = #private key

I think you are putting a lot of effort into stuff, that doesn't need to be handled by Django.
Here is what I would usually do:
Use HTTPS, as transport encryption layer
Use HTTP Basic Auth. Basic auth is implemented in urllib2 as well as requests.
But there is an even better solution: Django REST framework
It provides you will a full blown REST API including different authentication solutions.
If you need any help, setting up one of these options, let me know and I'll add an example.
May it be that you would use sentry for logging? Of course if it isn't task for training.
I look at the sentry since it been django application, and now it surely is excellent production-ready solution.
We're using it in banking-sphere software development.
You are very close to decrypting the values on the server. The result of the encryption on the client is a tuple. When you urllib2.unquote the items on the server, you then recreate tuples from them.
For example:
>>> c = public.encrypt('Hello', "ignored")
>>> c
('3\xae0\x1f\xd7\xe4b\xd4\xf1\xf4\x88!Be\xff!\x1e\xda\x82\x10\x9bRy\x0c\xa0v\xed\x84\xf9\xe35\xc6QG\xcf\xb7\x1b\xea\x9fe\t\x9b\x8d\xd6\xf3\x8cw\xde\x17\xb5\xf7\x9a+\x84i%#\x8a\xdf\xf4\xdd\xc8wY',)
which in your code you pack into params like this:
>>> params = { "message" : c }
>>> params
{'message': ('3\xae0\x1f\xd7\xe4b\xd4\xf1\xf4\x88!Be\xff!\x1e\xda\x82\x10\x9bRy\x0c\xa0v\xed\x84\xf9\xe35\xc6QG\xcf\xb7\x1b\xea\x9fe\t\x9b\x8d\xd6\xf3\x8cw\xde\x17\xb5\xf7\x9a+\x84i%#\x8a\xdf\xf4\xdd\xc8wY',)}
>>> urllib.urlencode(params)
'message=%28%273%5Cxae0%5Cx1f%5Cxd7%5Cxe4b%5Cxd4%5Cxf1%5Cxf4%5Cx88%21Be%5Cxff%21%5Cx1e%5Cxda%5Cx82%5Cx10%5Cx9bRy%5Cx0c%5Cxa0v%5Cxed%5Cx84%5Cxf9%5Cxe35%5Cxc6QG%5Cxcf%5Cxb7%5Cx1b%5Cxea%5Cx9fe%5Ct%5Cx9b%5Cx8d%5Cxd6%5Cxf3%5Cx8cw%5Cxde%5Cx17%5Cxb5%5Cxf7%5Cx9a%2B%5Cx84i%25%40%5Cx8a%5Cxdf%5Cxf4%5Cxdd%5Cxc8wY%27%2C%29'
I would guess that urllib2.unquote(p["message"]) returns this (but I did not try this):
"('3\\xae0\\x1f\\xd7\\xe4b\\xd4\\xf1\\xf4\\x88!Be\\xff!\\x1e\\xda\\x82\\x10\\x9bRy\\x0c\\xa0v\\xed\\x84\\xf9\\xe35\\xc6QG\\xcf\\xb7\\x1b\\xea\\x9fe\\t\\x9b\\x8d\\xd6\\xf3\\x8cw\\xde\\x17\\xb5\\xf7\\x9a+\\x84i%#\\x8a\\xdf\\xf4\\xdd\\xc8wY',)"
then you can recreate the tuple at the server like this (m is the unquoted message):
>>> from ast import literal_eval
>>> literal_eval(m)
('3\xae0\x1f\xd7\xe4b\xd4\xf1\xf4\x88!Be\xff!\x1e\xda\x82\x10\x9bRy\x0c\xa0v\xed\x84\xf9\xe35\xc6QG\xcf\xb7\x1b\xea\x9fe\t\x9b\x8d\xd6\xf3\x8cw\xde\x17\xb5\xf7\x9a+\x84i%#\x8a\xdf\xf4\xdd\xc8wY',)
once you have the tuple back, you can decrypt it:
>>> private.decrypt(literal_eval(m))
'Hello'
It would be better to find a vetted and standard mechanism to do this rather than roll your own. For example, in your scheme, I could capture different messages between the client and server, and then mix and match messages and username/password pairs, making it appear that the messages came from different users.
However, with just this minor tweak (recreating the tuples from the "unquoted" strings) your code should decrypt just fine.
In my settings.py, I put:
EMAIL_BACKEND = 'mailer.backend.DbBackend'
So even when importing from from django.core.mail import send_mail, the send_mail function still queues up the email in the database instead of sending it immediately.
It works just fine when actually running the website, but when testing the website, and accessing some webpages that trigger emails, emails are no longer queued anymore:
def test_something(self):
...
# Check no emails are actually sent yet
self.assertEquals(len(mail.outbox), 0) # test fails here -- 2 != 0
# Check queued emails.
messages = Message.objects.all()
self.assertEquals(messages.count(), 2) # test would also fail here -- 0 != 2
...
How come it doesn't seem to be using the backend when it is testing? (importing send_mail from mailer itself gets the tests to pass, but I can't really change the imports of other mailing apps like django-templated-email)
According to this question django overrides the setting.EMAIL_BACKEND when testing to 'django.core.mail.backends.locmem.EmailBackend'. It's also in the django docs here.
To properly test email with django-mailer, you need to override two settings:
Make the tests to use the django-mailer backend
Make the djano-mailer backend to use the test backend
If you don't set the django-mailer backend (number 2), your tests will try to send the email for real.
You also need to simulate running django-mailer's send_mail management command so that you can check mail.outbox for the correct email.
Here's an example of how to setup a test method:
from mailer.engine import send_all
#override_settings(EMAIL_BACKEND='mailer.backend.DbBackend')
#override_settings(MAILER_EMAIL_BACKEND='django.core.mail.backends.locmem.EmailBackend')
def test_email(self):
# Code that generates email goes here.
send_all() # Simulates running django-mailer's send_mail management command.
# Code to check the email in mail.outbox goes here.
This strategy makes your tests specific to django-mailer which you don't always want or need. I personally only use this setup when I'm testing specific functionality enabled by django-mailer. Otherwise, I use the default test email backend setup by django.
If you really want have sending of emails (like default) via SMTP in django tests use the decorator:
from django.test.utils import override_settings
#override_settings(EMAIL_BACKEND='django.core.mail.backends.smtp.EmailBackend')
class TestEmailVerification(TestCase):
...
Try the following:
django.core.mail.backends.console.EmailBackend
