python-requests CSRF verification failed

I'm trying to use a python script to access on a website
But it tells me CSRF verification failed. Request aborted. The python-requests code is as followed:
import requests
payload = {
'inUserName': 'NAN',
'inUserPass': 'NAN'
}
headers = {
'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like
Gecko) Chrome/103.0.0.0 Safari/537.36',
'From': 'https://pruebita.gob.pe/accounts/login/',
}
with requests.Session() as s:
p = s.post('https://pruebita.gob.pe/accounts/login/', data=payload, headers=headers)
print (p.text)
r = s.get('A protected web page url')
print (r.text)

How can I check that I logged in correctly with python requests?

I'm pretty new in python requests, and I have made a simple program, just to login, in netflix.
Here's my code.
url = 'https://www.netflix.com/login'
headers = {
'User-Agent' : 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko)
Chrome/80.0.3987.149 Safari/537.36'
}
r = requests.post(url, data={'userLoginId':'my-email', 'password': 'my-password'}, headers=headers)
print(r.status_code)
The output of status code is 200, so it's right

You could use a Session to check the results of your login.
s = requests.Session()
r = s.post(url, data={'userLoginId':'my-email', 'password': 'my-password'}, headers=headers)
print(r.status_code)
Then you could check the cookies for your session with:
s.cookies.getdict()

Post with python doesn't return the after login page

I'm trying to login to a specific game site using python, this is my code:
import requests
import webbrowser
s = requests.session()
url = "https://www.novaragnarok.com/"
myheaders = {'user_agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like
Gecko) Chrome/77.0.3865.120 Safari/537.36 OPR/64.0.3417.146'}
mydata = {'server':'NovaRO','username':'MyUsername','password':'MyPassword'}
r = s.post(url, data=mydata, headers=myheaders)
print(r.content)
Replacing MyUsername and MyPassword with my account doesn't return the page after Login, any hints on what I'm doing wrong?

There are two issues with your code.
First of all, you are sending the POST request to the wrong URL, try using this URL:
https://www.novaragnarok.com:443/?module=account&action=login&call=ajax
Secondly, I would recommend replacing your current headers with the following ones:
myheaders = {
"User-Agent": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:70.0) Gecko/20100101 Firefox/70.0",
"Origin": "https://www.novaragnarok.com",
"DNT": "1",
"Referer": "https://www.novaragnarok.com/",
"Upgrade-Insecure-Requests": "1",
}
hope this helps

error in $ failed reading not a valid json value when i try to send requests via python

so ive been trying to figure out how to do the 'follow' thing using python codes on imvu.com, but it always returns the message "invalid arguments" error in $: failed reading: not a valid json value"
import requests
headers = {
"Origin": "https://secure.imvu.com/",
"Referer": "https://secure.imvu.com/next/av/Sammy165/",
"User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/72.0.3626.109 Safari/537.36",
"X-IMVU-SAUCE": "" #removed sauce for account safety
}
url = "https://api.imvu.com/profile/profile-user-696969696/subscriptions"
data = {"id": "https://api.imvu.com/profile/profile-user-175389029"}
req = requests.post(url=url, headers=headers, data=data)
print(req.text)

Have you tried
requests.post(url=url, headers=headers, json=data)
?

You have to do json.dumps(data). See code below
import requests
import json
headers = {
"Origin": "https://secure.imvu.com/",
"Referer": "https://secure.imvu.com/next/av/Sammy165/",
"User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/72.0.3626.109 Safari/537.36",
"X-IMVU-SAUCE": "" #removed sauce for account safety
}
url = "https://api.imvu.com/profile/profile-user-696969696/subscriptions"
data = {"id": "https://api.imvu.com/profile/profile-user-175389029"}
req = requests.post(url=url, headers=headers, data=json.dumps(data))
print(req.text)
Output:
{"status":"failure","error":"ERROR-GENERIC-001","message":"Permission Denied: You are not allowed to modify this subscription set."}

Python 3.4 HTTP POST request with cookies

I'm having trouble constructing a method that will do a HTTP POST request with headers and data (username and password) and will retrieve the resulting cookies.
Here's my latest attempt so far:
def do_login(username, password):
headers = {"User-Agent": "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/39.0.2171.95 Safari/537.36",
"Accept": "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8"}
cj = http.cookiejar.CookieJar()
req = urllib.request.build_opener(urllib.request.HTTPCookieProcessor(cj))
data = {"Username": username, "Password": password}
req.open("http://example.com/login.php", data)
But I keep getting exceptions whenever I try to change the method. Also, will the response cookies be stored in the CookieJar cj, or is that used only for sending request cookies?

After some research it seems that the data cannot be passed directly as an argument to req.open, and it needs to be converted to a URL-encoded string. Here's the solution that worked for me:
headers = {"User-Agent": "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/39.0.2171.95 Safari/537.36",
"Accept": "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8"}
cj = http.cookiejar.CookieJar()
req = urllib.request.build_opener(urllib.request.HTTPCookieProcessor(cj))
req.addheaders = list(headers.items())
# The data should be URL-encoded and then encoded using UTF-8 for best compatilibity
data = urllib.parse.urlencode({"Username": username, "Password": password}).encode("UTF-8")
res = req.open("http://example.com/login.php", data)
