POST Request to add a AttachmentWrapper in Archer - python-3.x

I am trying to call a post request to upload a file to Archer. Please find my code below :
requests.packages.urllib3.disable_warnings(InsecureRequestWarning)
data = open('testdoc.txt','rb').read()
url = "http://rsaarcher/platformapi/core/content/attachment" #my archer url
token = "<my session id token>"
headers = {
'Accept':'application/json,text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
'Authorization': 'Archer session-id="'+token+'"',
'content-type': "application/json;",
'cache-control': "no-cache",
}
response = requests.request("POST", url, data=data, headers=headers, verify = False)
print(response.content)
print(response.status_code)
I am getting the following error :
b'{"Message":"The request contains an entity body but no Content-Type header. The inferred media type \'application/octet-stream\' is not supported for this resource.","ExceptionMessage":"No MediaTypeFormatter is available to read an object of type \'AttachmentWrapper\' from content with media type \'application/octet-stream\'.","ExceptionType":"System.Net.Http.UnsupportedMediaTypeException","StackTrace":" at System.Net.Http.HttpContentExtensions.ReadAsAsync[T](HttpContent content, Type type, IEnumerable1 formatters, IFormatterLogger formatterLogger, CancellationToken cancellationToken)\\r\\n at System.Web.Http.ModelBinding.FormatterParameterBinding.ReadContentAsync(HttpRequestMessage request, Type type, IEnumerable1 formatters, IFormatterLogger formatterLogger, CancellationToken cancellationToken)"}'
Status code : 415


Nakshatra, did you convert the file you're uploading to base64 beforehand?


Ahh, I realized the data you're sending is the incorrect formatted. It should be as follows:
{
"AttachmentName" : "myFile.docx",
"AttachmentBytes" : "[base64 here]"
}

Cloud Functions with Requests return 'Could not parse JSON' error

I'm running a cloud function in python to return some data from an api. The function is not executed and I have the error {'code': 400, 'message': 'Could not parse JSON'}.
Here is my code:
import requests
import json
def my_function(request):
url = 'https://blablabla/detailed'
headers = {'X-Api-Key': 'XXXXXXXX',
'content-type': 'application/json'}
data = '{"dateRangeStart":"2020-05-10T00:00:00.000","dateRangeEnd":"2020-05-16T23:59:59.000","amountShown": "HIDE_AMOUNT","detailedFilter":{ "page":"1","pageSize":"50"}}'
#req = requests.post(url, headers=headers, json=data)
req = requests.post(url, headers=headers, data=json.dumps(data))
print(req.json())
how should I format my data variable?

Just give your dict as your json argument, you don't need to specify the content-type headers requests will do it for you.
import requests
def my_function(request):
url = 'https://blablabla/detailed'
headers = {'X-Api-Key': 'XXXXXXXX', }
data = {"dateRangeStart": "2020-05-10T00:00:00.000", "dateRangeEnd": "2020-05-16T23:59:59.000", "amountShown": "HIDE_AMOUNT", "detailedFilter": { "page": "1", "pageSize": "50", }, }
req = requests.post(url, headers=headers, json=data)
print(req.json())
If you do not set a content-type header will try to set it for you:
When using the keyword argument json: it will set it to application/json
When using the keyword argument data (and the value passed respects some criteria, most of the time you don't have to worry about it): it will set it to application/x-www-form-urlencoded
If both kwargs are present data takes priority for the header so it will be set to application/x-www-form-urlencoded
I have not detailed the behaviour when the kwarg files is used as it would be really lengthy and is out of scope here.
Here's the source code.

Google Oaut2 - Python using requests whiout Library

I am trying to authenticate not google by means of requests if I use the api but I don't know what I put in the "code" field and it will work, you can help me, or the code follows below.
import requests
url = "https://accounts.google.com/o/oauth2/token"
payload='grant_type=authorization_code&client_secret=xxxxx&client_id=xxxx&redirect_uri=https%3A%2F%2Fpushsistemas.com.br%2F&code='
headers = {
'content-type': 'application/x-www-form-urlencoded',
'Cookie': 'NID=219=RgUebbUM4k3WX0uQr8HVcIZkQ5-rMrb4HHnfnRzNTxUse776sG6-LItgXwpdv-MmaFYf3Tu4otJN-UfP70OzDtdnfam2dwAZkd6yMsr8BW_7lGE4FTaas9QkoG-hOMqXgYEHvI4YK39dWgXhWnL0E5LcsOv0DXnfjJ2kUf7VlTs; __Host-GAPS=1:jGXTa0ipDEC58oJF7pZwNBVeSXCQRw:3IRHy3GC9mAq4nqt'
}
response = requests.request("POST", url, headers=headers, data=payload)
This output
{
"error": "invalid_request",
"error_description": "Missing required parameter: code"
}
if it is not possible to do this way could you send me how to do it using the google library?

pisignage API login error: "This username/email is not registered or active"

From there api docs, I have created a request to login and get the token. The code is under below, it returns 401 . The credentials are right and I can log in from web, but through API I can not.
import requests
import json
params_dict = {
"email": "example#mail.com",
"password": "example",
"getToken": True
}
response = requests.post(
'https://example.piathome.com/api/session',
data=params_dict
# headers={'Content-type': 'application/json', 'accept': 'application/json'} returns 500
)
json_response = response.json()
print(json_response)

Make sure that the API endpoint is set to username.pisignage.com (not just pisignage.com).
And the headers are absolutely required. Request and Response types must be set to application/json.

Python - Basic Authorization (OAuth2.0) to retrieve access token from API

I'm trying to generate an access token from an API using the following required information:
Authorization endpoint: https://api.paylocity.com/IdentityServer/connect/token
Authorization Header
The request is expected to be in the form of a basic authentication request, with the "Authorization" header containing the client-id and client-secret. This means the standard base-64 encoded user:password, prefixed with "Basic" as the value for the Authorization header, where user is the client-id and password is the client-secret.
Content-Type Header
The "Content-Type" header is required to be "application/x-www-form-urlencoded".
Other Values
The request must post the following form encoded values within the request body:
grant_type = client_credentials
scope = WebLinkAPI
I've tried using the Python 'requests' package without success, see below:
import requests
url = "https://api.paylocity.com/IdentityServer/connect/token"
headers = {
'Authorization': "Basic **********:**********",
'Content-Type': "application/x-www-form/urlencoded"
}
body = {
'grant_type': "client_credentials",
'scope': 'WebLinkAPI'
}
response = requests.request("POST", url, headers=headers, params=body)
print(response.text)
Instead of an access token, I receive an error message:
{"error":"invalid_client"}
I've verified that my base64 encoded username and password are correct, it looks something like "G/RaNdOm:MoReRaNdOm==" and when I add them to postman it works so my credentials are correct. What could be wrong?

I resolved this. There were two issues, the Authorization header was not using ASCII as the destination charset with base64 encoding. The other issue was trying to add the additional values to the parameters instead of the body in the requests package. The solution was to replace "params" with "data". Here was the solution:
url = "https://api.paylocity.com/IdentityServer/connect/token"
body = "grant_type=client_credentials&scope=WebLinkAPI"
headers = {
'Content-Type': "application/x-www-form-urlencoded",
'Authorization': "Basic ***(base64ASCII)username:password***",
}
response = requests.request("POST", url, data=body, headers=headers)
print(response.text)

For some reason im getting the error "HTTP 415 Unsupported Media Type".
I'm trying to send a csv, along with some json in a multipart form. I originally had this working with http.client but the way I was doing it it was adding extra line breaks and carriage return literals into the multipart message body.
Any help greatly appreciated!

The issue I couldnt originally see was with declaring the file type in the file tuple, shown below as 'text/csv' in the solution.
import http.client
file = { 'file' : ('csvtest.csv', open('csvtest.csv', 'rt'), 'text/csv') }
payload = { 'parser' : '{object trimmed for comment}' }
headers = { 'accept': "application/json", 'authorization': "Basic ZGxhZG1pbjp0aGlua2JpZw==", }
url = "http://localhost:8400/proxy/v1/schema-discovery/hive/sample‌​-file"
req = requests.post(url, data=payload, files=file, headers=headers)
pprint(req.text)
