Telegram Bot SendDocument pdf

I am having a real headache with the way of sending a pdf file to a Telegram Bot.
Apparently I am following the documentation but never get it sent.
I am using the url: https://api.telegram.org/botBOTID/sendDocument?chat_id=CHATID&document=/home/lix/Downloads/2.pdf
It is a pdf file storaged locally, but I think it is just the way I am presenting it.
The error getting is:
{"ok":false,"error_code":400,"description":"Bad Request: URL host is empty"}
Does anybody knows how to send a pdf local file?
Many thanks

You should send a POST request, with the PDF as a payload, using the Python Requests library, your code should look something like this:
import requests
# Url with bot token + user id
url = "https://api.telegram.org/bot<MY-BOT-TOKEN>/sendDocument?chat_id=<MY_CHAT_ID>"
# Create payload with PDF file
payload = {}
files = [
('document', open('/home/lix/Downloads/2.pdf','rb'))
]
headers= {}
# Request
response = requests.request("POST", url, headers=headers, data = payload, files = files)
# Log reponse as UTF-8
print(response.text.encode('utf8'))

Upload a file using python requests

I have a problem trying to upload a file into an API. In the swagger UI I have not problem uploading an excel file manually. When I try tu upload using request, I recive a 415 error (Invalid format of my file). Here is a simple code of that post request:
headers = {
'Authorization':"bearer "+ CLIENT.token,
'Content-Type': 'form-data'
}
files = [('file', open(path_to_file, 'rb'))]
response = requests.post(api_url,
files=files,
headers=headers)
My response has status code 415, I dont Know what is happening. When I used the swagger, I inspected the newtwork browser, and I saw this header in the request
Content-Type: multipart/form-data; boundary=----WebKitFormBoundarywkrdGd3ROh0GkfsW
But, I don't know what is the term "boundary", and if I pass this header manually into the requests, the API throws a 500.

The server is saying that your Content-Type is wrong. If you're uploading a .xls file use:
'Content-Type': 'application/vnd.ms-excel'
If you're uploading a .xlsx file use:
'Content-Type': 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet'

How python flask server send back response with XML file

I coded a mock server, after I got a POST message with XML file, I need send back a response message with XML file also.
I found some example as below to send back response with XML content. But I think it's not a file. Anyone has idea on sending back response with a file?
result = open('output.xml', 'r').read()
r = Response(response=result, status=200, mimetype="application/xml")

Send a request to webservice via an xml file?

I have a webservice running at "tcs-webdev2:8200/scheduler/requestgroup" to which new build requests can be sent using an xml file(sample xml file below). I need some guidance
on how requests to a webserive via n xml file work.
Sample xml file:-
<BuildInfo>
<BuildSource>DEV_CI</BuildSource>
<SoftwareProductBuild>MAAAAANLGD0000211.1_101</SoftwareProductBuild>
<PriorrootBuild>MAAAAANLGD0000211.1</PriorrootBuild>
<NewSIBuilds>
<Image>
<Type>LNX</Type>
<SoftwareImageBuild>buildlocation</SoftwareImageBuild>
<Location>\\\sever\buildlocation\checkout</Location>
<Variant>Default</Variant>
<LoadType>Debug</LoadType>
</Image>
</NewSIBuilds>
</BuildInfo>

It depends on your web service, how exactly you need to send the request, but you have to something like the following:
import httplib
with open("your_xml_filename.xml") as f:
body = f.read()
headers = {"Content-type": "application/xml"}
conn = httplib.HTTPConnection("tcs-webdev2", 8200)
conn.request("POST", "/scheduler/requestgroup", body, headers)
response = conn.getresponse()
print( response.status )
print( response.read())
conn.close()
It assumes that tcs-webdev2 is a valid hostname (if not, you can use the IP address). Also this request is an HTTP POST, your service might need different request type. Also some additional headers and authentication might be needed.
