Making the right post request

I need your help in putting together a post request.
The output I get is html, but the plan was to get the following:
Below are all the data for the desired item:

x-requested-with: XMLHttpRequest
Please help me figure out how I can get what I want.
My code:
import requests
import cloudscraper
scraper = cloudscraper.create_scraper()
url = 'https://dgslivebetting.betonline.ag/ngwbet.aspx/gvFrameHtml'
data = {"gameID":0}
headers = {
"User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/107.0.0.0 Safari/537.36",
'Referer': "https://dgslivebetting.betonline.ag/ngwbet.aspx/gvFrameHtml"
}
r = requests.post(url, data=data, headers=headers)
print(r.text)

In order to get JSON back, you need to add the Content-Type header to your request.
Your current examples shows you are only sending these headers:
headers = {
"User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/107.0.0.0 Safari/537.36",
'Referer': "https://dgslivebetting.betonline.ag/ngwbet.aspx/gvFrameHtml"
}
At the very least, you'll need to add Content-Type: application/json; charset=UTF-8 to the request, otherwise, requests is doing an application/x-www-form-urlencoded form post which is why you're getting back HTML from this site instead of JSON.

Fatal erro in POST using request module Python 3

I'm working on a web scraper build in python. Until now I build the following code:
import requests
headers = {
'authority': 'truegamedata.com',
'accept': '*/*',
'x-requested-with': 'XMLHttpRequest',
'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/88.0.4324.152 Safari/537.36',

'accept-language': 'pt-BR,pt;q=0.9,en-US;q=0.8,en;q=0.7',
}
data = {
'weapon_name': '^%^5B^%^22Kilo 141^%^22^%^2C^%^22wz^%^22^%^5D'
}
response = requests.post('https://truegamedata.com/SQL_calls/base_data.php', headers=headers, data=data)
print(response.text)
For some reason, I get the following error:
<br />
<b>Fatal error</b>: Uncaught Error: Call to a member function execute() on bool in /home/customer/www/truegamedata.com/public_html/SQL_calls/base_data.php:29
Stack trace:

thrown in <b>/home/customer/www/truegamedata.com/public_html/SQL_calls/base_data.php</b> on line <b>29</b><br />
Does anyone know why this is happening? And how I can get this response?
Here is the request from Chorme Dev tools:

I tried to give as much information as possible, if anything is missing let me know

Download file after POST form submission

I am trying to download the file from here.
In Firefox, the link redirects me to a webpage where I have to log in with my credentials. After doing so, Firefox automatically prompts me to save the desired file with a pop-up windows.
I am trying to replicate that behavior with Python without success.
I've tried the code from this question, namely
import requests
session = requests.session()
url = "https://metamap.nlm.nih.gov/download/public_mm_linux_main_2020.tar.bz2"
data= {'username': 'xxxxx', 'password':'xxxxxx'}
session.post(url, data=data)
response = requests.get("https://metamap.nlm.nih.gov/download/public_mm_linux_main_2020.tar.bz2")
print(response.text)
Insights from Firefox
Using the Network tab from the Developer Mode, I have been able to see the following:
The POST request, apart from username and password sends also an execution parameter, which seems to be very long hashed string. I don't know what this is or how to replicate this.
POST /cas/login?service=https%3a%2f%2fmetamap.nlm.nih.gov%2fdownload%2fpublic_mm_linux_main_2020.tar.bz2 HTTP/1.1

Cookie: TGC=exxxxxx; JSESSIONID=xxxxx
Upgrade-Insecure-Requests: 1
Afterwards, there is a GET request to the same address with a ticket parameter.
GET /download/public_mm_linux_main_2020.tar.bz2?ticket=xxxxxx HTTP/1.1
Host: metamap.nlm.nih.gov
User-Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:79.0) Gecko/20100101 Firefox/79.0

Connection: keep-alive
Cookie: MOD_AUTH_CAS_S=xxxxxx
Upgrade-Insecure-Requests: 1
Finally, another GET triggers the download.
GET /download/public_mm_linux_main_2020.tar.bz2 HTTP/1.1
Host: metamap.nlm.nih.gov
User-Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:79.0) Gecko/20100101 Firefox/79.0

Connection: keep-alive
Cookie: MOD_AUTH_CAS_S=xxxxx
Upgrade-Insecure-Requests: 1
In between all of this, cookies are set and read.
I don't know what information is useful. I'm putting here all that I can see.
Than you in advanced.
EDIT:
After more exploration I am trying to replicate the 3 request pattern seen in Mozilla/Chrome.
This is my code now:
import requests
url_1 = "https://utslogin.nlm.nih.gov/cas/login"
# url_2 = "https://metamap.nlm.nih.gov/download/public_mm_linux_main_2020.tar.bz2"
params = {'service': 'https%3a%2f%2fmetamap.nlm.nih.gov%2fdownload%2fpublic_mm_linux_main_2020.tar.bz2'}

execution and submit are parameters also passed during the POST request. With the first GET I emulate the normal loading of the page, after which a cookie is given to me. Using that cookie and submitting the form, I expect to get back another cookie and a ticket with which to download the file. However, instead of getting this, what I see in output is the response header of another GET as is anything had happened.
By the way, to whomever wants to help me: the credentials from that site are acquired prior by registering and some hours may pass between registration and credential arrival.

When you run this code, the following packet is created:

Look. The boundaries set and the boundaries actually applied are different.
What is the problem?

I suppose you use requests library. It doesn't allow to setup boundaries. So it is generated automatically on the fly.

Send HTTP Post with Python

I want to make a program where I can send HTTP post requests and respond.
So, I want to send THIS post:
POST https: //example.com/index.php?s=&&app=box&module=ajax&section=coreAjax&secure_key=&type=submit&lastid=87311&global=1 HTTP/1.1
Host: example.com
Connection: keep-alive
Content-Length: 10
Accept: text/javascript, text/html, application/xml, text/xml, */*
X-Prototype-Version: 1.7.2
Origin: https://example.com
X-Requested-With: XMLHttpRequest
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/56.0.2924.87 Safari/537.36
Content-type: application/x-www-form-urlencoded; charset=UTF-8
Referer: https://x.com/
Accept-Encoding: gzip, deflate, br
Accept-Language: en-US,en;q=0.8
Cookie: cookieconsent_status=dismiss;
And then enter the request body:
message= # Which I will make: "message= %s" % (messagex))
But I do not know how to send them and can´t seem to find any way online, could someone help please?

The main parts are:
import requests # you have to install this library, with pip for example
# define your custom headers (as many as you want)
headers = {
'X-Prototype-Version': '1.7.2'
}
# define your URL params (!= of the body of the POST request)
params = {
'your_first_param': 'its_value',
'your_second_param': 'its_value'
}
# define the body of the POST request
data = {
'message' : 'your message'
}
# send the POST request
response = requests.post('https://example.com/index.php', params=params, data=data, headers=headers)
# here is the response
print response.text
Hope that helps.
