Fill a form with a captcha solving script using requests - request

So basically the script running perfectly, I get the feedback that my Captcha has been solved. But the problem lies when the script enters the rest of the form's input.
Any idea where it is coming from?
import requests
from random import randint
from time import sleep
# Add these values
API_KEY = 'ApiKey' # Your 2captcha API KEY
site_key = 'SiteKey' # site-key, read the 2captcha docs on how to get this
url = 'https://site' # example url
proxy = 'proxy' # example proxy
proxy = {'http': 'http://' + proxy, 'https': 'https://' + proxy}
s = requests.Session()
# here we post site key to 2captcha to get captcha ID (and we parse it here too)
captcha_id = s.post("http://2captcha.com/in.php?key={}&method=userrecaptcha&googlekey={}&pageurl={}".format(API_KEY, site_key, url), proxies=proxy).text.split('|')[1]
# then we parse gresponse from 2captcha response
recaptcha_answer = s.get("http://2captcha.com/res.php?key={}&action=get&id={}".format(API_KEY, captcha_id), proxies=proxy).text
print("solving ref captcha...")
while 'CAPCHA_NOT_READY' in recaptcha_answer:
sleep(5)
recaptcha_answer = s.get("http://2captcha.com/res.php?key={}&action=get&id={}".format(API_KEY, captcha_id), proxies=proxy).text
recaptcha_answer = recaptcha_answer.split('|')[1]
# we make the payload for the post data here, use something like mitmproxy or fiddler to see what is needed
payload = {
'username' : 'username',
'password' : 'password' ,
'password_again' : 'password' ,
'email' : 'email#gmail.com' ,
'key': 'value',
'gresponse': recaptcha_answer # This is the response from 2captcha, which is needed for the post request to go through.
}
# then send the post request to the url
response = s.post('https://site',payload, proxies=proxy)

You only need to change 'gresponse' to 'g-recaptcha-response' and it's working perfectly

How do i pass django-rest-framewor backend session details to react front end?

I am trying to make a music controller room with django backend and react frontend. These are running on two different localhost servers, 3000 and 8000. I am using django session's session_key attribute to be able to identify who the host(the person who created the room) is. If the user using the app in the frontend creates a room and comes back to create another room before the session expires, the user should be taken to the room they have created instead of having the backend create another room. My problem is that each time I hit the create room button on the frontend seconds after creating another room(obviously the session hasn't expired so I expect to be taken to the previous room), the fetch method returns a new room.
Here is a view in my views.py that handles this POST request:
class CreateRoomview(APIView):
# declaring the class we are going to serialize our data with.
serializer_class = CreateRoomSerializer
# manually defining the method we will use to handle post data from our frontend
def post(self, request, format=None):
'''
a check to see if in any of our rooms we have a room that that has a host with the
current session key. We are filtering out all those rooms that have a host with
the current session key.
'''
if not self.request.session.exists(self.request.session.session_key):
self.request.session.create()
serializer = self.serializer_class(data=request.data)
# if not Room.objects.filter(host=self.request.session.session_key).exists():
# # if the room does not exist, we create a session like that.
# self.request.session.create()
# we serialize our request data
serializer = self.serializer_class(data=request.data)
# check to see if the data we have serialized is valid
if serializer.is_valid():
# define those three attributes of our model to be those values.
guest_can_pause = serializer.data.get('guest_can_pause')
votes_to_skip = serializer.data.get('votes_to_skip')
host = self.request.session.session_key
# obtain a queryset with the newly defined host.
queryset = Room.objects.filter(host=host)
# if the queryset is not empty,
if queryset.exists():
# assign a room to the first entry in the queryset.
room = queryset[0]
# assign those room attributes to the values we defined above.
room.guest_can_pause = guest_can_pause
room.votes_to_skip = votes_to_skip
# do not create a new room, but rather,update the values we only
# only want to change
room.save(update_fields=['guest_can_pause', 'votes_to_skip'])
# if the queryset is empty,
else:
# create a room with the values specified
room = Room(host=host, guest_can_pause=guest_can_pause,
votes_to_skip=votes_to_skip)
room.save()
return Response(RoomSerializer(room).data, status=status.HTTP_201_CREATED)
Here is method in one of my react frontend components that sends the POST request:
handleRoomButtonClicked() {
const requestOptions = {
method: "POST",
headers: {
"Content-Type": "application/json",
},
body: JSON.stringify({
votes_to_skip: this.state.votes_to_skip,
guest_can_pause: this.state.guest_can_pause,
}),
};
fetch("http://127.0.0.1:8000/api/createroom/", requestOptions)
.then((response) => response.json())
.then((data) => console.log(data));
}
Background information
Im using django-cors-headers to allow for cross origin requests since my backend and frontend are runnig on two different ports.
i have CORS_ALLOW_ALL_ORIGINS = True in my settings.py.
I have tried to search for similar questions on stack but none were helpful, I forgot to save their links so I can attach to this question

Invalid grant type passed - STK request

I keep getting this error every time I try to make an STK push
"requestId" => "6255-20728117-1"
"errorCode" => "400.008.02"
"errorMessage" => "Invalid grant type passed"
Check the url you are using and add the grant_type and ensure that the grant_type is associated with a customer_key as well as a customer_secret in the final post request
e.g
curl -X GET https://sandbox.safaricom.co.ke/oaut/v1/generate?grant_type=client_credentials
As opposed to:
curl -X GET https://sandbox.safaricom.co.ke/oauth/v1/generate
sample code snippet is as follows
consumer_key = keys.consumer_key
consumer_secret =keys.consumer_secret
api_URL = (
"https://sandbox.safaricom.co.ke/oauth/v1/generate?grant_type=client_credentials"
)
r = requests.get(api_URL, auth=HTTPBasicAuth(consumer_key, consumer_secret))
print(r.text)
You have to provide a grant_type in your request. Check the Mpesa Api Documentation.

Unable to download a document from google cloud storage

I am able to upload a document and download the document from google cloud storage for signed url using httpclient in java.But,when i put the same signed url in browser i am unable to download document for the link.I am getting following error
The request signature we calculated does not match the signature you
provided. Check your Google secret key and signing method.`
But when i mark check shared publicly check box in storage browser i am able to download from the generated signed url.But i want to allow a user to download a document from the browser without marking it as shared publicly.
.
I want to get confirm on some confusing part like
For document to get accessible by user who does not have google account after creating a signed url also i have to check shared publicly check box in storage browser?
But i think if the url is signed then it should not be check for shared publicly checkbox and user who does not have google account can access the document?But in my case it is not happening .According to link
https://developers.google.com/storage/docs/accesscontrol#About-CanonicalExtensionHeaders
it talks about Canonicalized_Extension_Headers .So i put in my request header
request.addHeader("x-goog-acl","public-read");
This is my code
// construct URL
String url = "https://storage.googleapis.com/" + bucket + filename +
"?GoogleAccessId=" + GOOGLE_ACCESS_ID +
"&Expires=" + expiration +
"&Signature=" + URLEncoder.encode(signature, "UTF-8");
System.out.println(url);
HttpClient client = new DefaultHttpClient();
HttpPut request = new HttpPut(url);
request.addHeader("Content-Type", contentType);
request.addHeader("x-goog-acl","public-read");// when i put this i get error
request.addHeader("Authorization","OAuth 1/zVNpoQNsOSxZKqOZgckhpQ");
request.setEntity(new ByteArrayEntity(data));
HttpResponse response = client.execute(request);
When i put request.addHeader("x-goog-acl","public-read");i get error
HTTP/1.1 403 Forbidden error .
.But when i remove this line it is uploaded successfully .It seems like i need to set
request.addHeader("x-goog-acl","public-read") to make it publicly accessible but on putting this on my code i am getting error.
.Any suggestion Please?
Finally Solved it.
To run singed url from browser you have to set HTTP header . In https://developers.google.com/storage/docs/accesscontrol#Construct-the-String
Content_Type Optional. If you provide this value the client (browser) must provide this HTTP header set to the same value.There is a word most.
So if you are providing Content_Type for sign string you must provide same Content_Type in browser http header.When i set Content_Type in browser header this error finally solved
this works for me:
set_include_path("../src/" . PATH_SEPARATOR . get_include_path());
require_once 'Google/Client.php';
function signed_storageURL($filename, $bucket, $p12_certificate_path, $access_id, $method = 'GET', $duration = 3600 )
{
$expires = time( ) + $duration*60;
$content_type = ($method == 'PUT') ? 'application/x-www-form-urlencoded' : '';
$to_sign = ($method."\n"."\n".$content_type."\n".$expires."\n".'/'.$bucket.'/'.$filename);
$signature = '';
$signer = new Google_Signer_P12(file_get_contents($p12_certificate_path), 'notasecret');
$signature = $signer->sign($to_sign);
$signature = urlencode( base64_encode( $signature ) );
return ('https://'.$bucket.'.commondatastorage.googleapis.com/'.$filename.'?GoogleAccessId='.$access_id.'&Expires='.$expires.'&Signature='.$signature);
}
$url = signed_storageURL(rawurlencode("áéíóú espaço & test - =.jpg"),'mybucket', 'mykey.p12','myaccount#developer.gserviceaccount.com');
echo ''.$url.'';

Basic Authentication in CakePHP

I am trying to setup Basic Authentication for my CakePHP app so I can use it as an API for an upcoming mobile application. However If I pass the following:
cameron:password#dev.driz.co.uk/basic/locked/
Where cameron is the username, password is the password, and the rest is the domain and application. locked is a method that requires authentication. (obviously the password is wrong in this example)
(Q1) I will be requested for a username and password in a prompt... but the username and password are in fact correct as if I then type them into the prompt they work... Why would this happen? Haven't I just passed the username and password?
I can't see anything wrong with the way I have set this up in CakePHP.
I set Basic Auth in AppController as:
public $components = array('Auth');
function beforeFilter()
{
parent::beforeFilter();
$this->Auth->authorize = array('Controller');
$this->Auth->authenticate = array('Basic');
$this->Auth->sessionKey = false;
$this->Auth->unauthorizedRedirect = false;
}
(Q2) Even so I have set both sessions to be false and the redirect to false, if the user cancels the prompt then they are redirected to the login page? Any ideas on how to stop this from happening? Ideally I want to send back a JSON response or status code of 401 (depending if it's an AJAX request or not).
So something like:
if ($this->request->is('ajax')) {
$response = json_encode(
array(
'meta'=>array(
'code'=>$this->response->statusCode(401),
'in'=>round(microtime(true) - TIME_START, 4)
),
'response'=>array(
'status'=>'error',
'message'=>'401 Not Authorized'
)
)
);
// Handle JSONP
if(isset($_GET['callback'])) {
$response = $_GET['callback'] . '(' . $response . ')';
}
// Return JSON
$this->autoRender = false;
$this->response->type('json');
$this->response->body($response);
} else {
header('HTTP/1.0 401 Unauthorized');
}
But where would this go in the application logic to show this? It needs to happen for ALL requested methods that require authentication and user fails or cancels the authentication.
(Q3) If you enter incorrect details you are just shown the prompt again until you get the username/password correct or hit cancel. How can I make it show an error?
Any ideas for these three issues (marked as sub questions numbers).
Update: This is how I send the headers to the API:
"use strict";jQuery.base64=(function($){var _PADCHAR="=",_ALPHA="ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/",_VERSION="1.0";function _getbyte64(s,i){var idx=_ALPHA.indexOf(s.charAt(i));if(idx===-1){throw"Cannot decode base64"}return idx}function _decode(s){var pads=0,i,b10,imax=s.length,x=[];s=String(s);if(imax===0){return s}if(imax%4!==0){throw"Cannot decode base64"}if(s.charAt(imax-1)===_PADCHAR){pads=1;if(s.charAt(imax-2)===_PADCHAR){pads=2}imax-=4}for(i=0;i<imax;i+=4){b10=(_getbyte64(s,i)<<18)|(_getbyte64(s,i+1)<<12)|(_getbyte64(s,i+2)<<6)|_getbyte64(s,i+3);x.push(String.fromCharCode(b10>>16,(b10>>8)&255,b10&255))}switch(pads){case 1:b10=(_getbyte64(s,i)<<18)|(_getbyte64(s,i+1)<<12)|(_getbyte64(s,i+2)<<6);x.push(String.fromCharCode(b10>>16,(b10>>8)&255));break;case 2:b10=(_getbyte64(s,i)<<18)|(_getbyte64(s,i+1)<<12);x.push(String.fromCharCode(b10>>16));break}return x.join("")}function _getbyte(s,i){var x=s.charCodeAt(i);if(x>255){throw"INVALID_CHARACTER_ERR: DOM Exception 5"}return x}function _encode(s){if(arguments.length!==1){throw"SyntaxError: exactly one argument required"}s=String(s);var i,b10,x=[],imax=s.length-s.length%3;if(s.length===0){return s}for(i=0;i<imax;i+=3){b10=(_getbyte(s,i)<<16)|(_getbyte(s,i+1)<<8)|_getbyte(s,i+2);x.push(_ALPHA.charAt(b10>>18));x.push(_ALPHA.charAt((b10>>12)&63));x.push(_ALPHA.charAt((b10>>6)&63));x.push(_ALPHA.charAt(b10&63))}switch(s.length-imax){case 1:b10=_getbyte(s,i)<<16;x.push(_ALPHA.charAt(b10>>18)+_ALPHA.charAt((b10>>12)&63)+_PADCHAR+_PADCHAR);break;case 2:b10=(_getbyte(s,i)<<16)|(_getbyte(s,i+1)<<8);x.push(_ALPHA.charAt(b10>>18)+_ALPHA.charAt((b10>>12)&63)+_ALPHA.charAt((b10>>6)&63)+_PADCHAR);break}return x.join("")}return{decode:_decode,encode:_encode,VERSION:_VERSION}}(jQuery));
$(document).ready(function(){
var username = 'cameron';
var password = 'password';
$.ajax({
type: 'GET',
url: 'http://dev.driz.co.uk/basic/locked',
beforeSend : function(xhr) {
var base64 = $.base64.encode(username + ':' + password);
xhr.setRequestHeader("Authorization", "Basic " + base64);
},
dataType: 'jsonp',
success: function(data) {
console.log(data);
},
error: function(a,b,c) {
//console.log(a,b,c);
}
});
});
Q1
You don't specify how you visit the protected URL (dev.driz.co.uk/basic/locked). Are you sure that the way you are doing it you are setting up the request headers properly? You need to Base64 encode the username/password.
When your first request fails the browser jumps in with the prompt and to be succeeding means that the browser does it properly for you the second time.
Have a look at you request headers to see what you send the first time and what the browser sends the second.
Q2
When basic auth fails your server sends a 401 with a header WWW-Authenticate:Basic which is picked up from the browser and you are presented with the prompt. That is build in normal behavior for all browsers since ages, you can't change that.
About your issue with canceling and being redirected to login, Auth had some API changes after 2.4 that are highlighted in the book. Before version 2.4 you are always redirected to loginAction.
Finally, let Auth do the work for you by setting it up properly and don't attempt to hardwire the responses yourself like in the code you suggest. You also shouldn't ever be using php's header() in cakephp, use CakeRequest::header() instead.
Q3
Answered in Q2, you can't have Basic and 401 not trigger the prompt. Either change the required authentication header (by perhaps setting a name like Basic-x instead of Basic) or don't send the response code 401 on failure but send i.e. 200 or 400 and add an error message explaining the situation.
