I am working on Instagram API in Django(python)
I am getting code from
'https://api.instagram.com/oauth/authorize/?client_id=%s&response_type=code&redirect_uri=%s' % (INSTAGRAM_APP_CONSUMER_KEY, redirect_uri)
but when i am exchanging code for access token code is failing
# All arguments are valid
def execute(self, code, redirect_uri, app_id, app_secret):
exchange_url = 'https://api.instagram.com/oauth/access_token'
try:
#Update : get request to post
r = requests.post(exchange_url, params={
'client_id': app_id,
'redirect_uri': redirect_uri,
'client_secret': app_secret,
'code': code,
'grant_type': 'authorization_code'
})
#print(r)
#print(json.loads(r))
print(r.json())
return r.json()
except Exception as e:
print(e)
r.json() gives simplejson.scanner.JSONDecodeError: Expecting value: line 1 column 1
Update 1 : r.json() works after request changed from get to post but error
message comming 'You must provide a client_id'
Please let me know what i am doing wrong
I think it requires data in post data, not in query params.
Try this :
your_post_data = {'client_id': '', ... }
r = requests.post('your_url', data=your_post_data)

I have just started learning ruby and trying to learn extracting web data. I am using samplewebapp code given in a sites API documentation
On executing the test.rb file as given below it generates a token.
The token.json file contains the following
{"access_token":"eyJ0eXAiOiJKV1QiLCJhbGciOiJSUzI1NiJ9.eyJhdWQiOiIzY2U1NjFhMC01ZmE5LTQ5NjUtYTQ2Mi01NmI2MzEzNjRlZGMiLCJqdGkiOiJmMjc0ZTgwM2FmZjVlMTFiMTAzNzIwMzAwNzRlNDRhZDE3ODg3ZjAzOGQ2ODk0OWIwNzVkMmQ5N2E2MjAwYzc5ZWRhNzU4MmQ3MTg1MTc1YiIsImlhdCI6MTY1NDU2OTc0MS41MjgxNTUsIm5iZiI6MTY1NDU2OTc0MS41MjgxNTcsImV4cCI6MTY1NDU3MzM0MS41MjgwMzksInN1YiI6IjE5NGFlNTU5LTU5OWMtNDQ2ZC1hOTRhLWM2MTIyYjZkMTA2ZiIsInNjb3BlcyI6W10sImNyZWRpdHNfcmVtYWluaW5nIjo0NzAwLCJyYXRlX2xpbWl0cyI6W3sicmF0ZSI6NSwiaW50ZXJ2YWwiOjYwfV19.XoN5A-H8Z7d8p_0e2rCcyV4yWO9MAF3TZlHk5VP5NjUEqtTXTVYKfKuzidYDs7K8ZzAtWzyt3aR5VSUG0_nw-uPd7Z3_Y75alQMqa2b5rHGn5JFWH7nuAriskr26WSCqAdj4cNjccPORryRr5sYKwpE4Y4kTG0IX_8frvwYxwp-8wFpLLj98K3axwN7CCpWdnPDSzuMqmH6tSpF0XhdYxB5LTVH0AyH7lN0S0_Lftq0b3sOLIvEaTfNkuRGNqwLkBYFkHFuPqwrKd8RJhC2W1QZhrmUw3eYnh-0iQABGk2V0skIqDlb6BbQ5GFX6MXgiXAc-h5Ndda7pZ5N5UCQU3g","expires_at":1654573341}
However it also generates a JSON parser error as under
/Users/mm/.rbenv/versions/3.0.4/lib/ruby/3.0.0/json/common.rb:216:in `parse': 809: unexpected token at '' (JSON::ParserError)

from /Users/mm/Desktop/prokerala/client.rb:21:in `parseResponse'
from /Users/mm/Desktop/prokerala/client.rb:99:in `get'
I googled around for a while and some of the responses talk about the issues between double and single quotes.. I tried changing those also but it doesn't work.
I have also tried running it with system ruby - which gives a different error
Would appreciate very much if someone could explain what the error is / logic behind this.. Also I am not clear about the error message itself. The message talks about parse error 809:"unexpected token" on column no 809 of the token there is nothing.. Am i reading it wrong?

running the test file using ruby 3.0.4 gives the a JSON parse error. Full error reproduced as below
/Users/mm/.rbenv/versions/3.0.4/lib/ruby/3.0.0/json/common.rb:216:in `parse': 809: unexpected token at '' (JSON::ParserError)
from /Users/mm/.rbenv/versions/3.0.4/lib/ruby/3.0.0/json/common.rb:216:in `parse'

from /Users/mm/Desktop/prokerala/client.rb:99:in `get'
from test.rb:11:in `<main>'
I executed the above code and from this, we are getting
#<Net::HTTPMovedPermanently 301 Moved Permanently readbody=true> as response
and response body as empty string '', which results in error in parsing the body.
Since, API endpoint is secure with https, we need set use_ssl: true before starting the session. Try below code and it will fix the issue.
res = Net::HTTP.start(uri.hostname, use_ssl: true) do |http|
http.request(req)

I am using boto3 with Python 3.6 to start a Step Function execution. The Step Function is designed to share my base AMI across all my accounts. I have 4 variables I need to pass to the input parameter to kick off the execution. These are the AMI ID, the account list of accounts I own, the source account, and the KMS key. The AMI ID and the account list are constructed in my code and are the variables that need to get passed dynamically. According to the documentation, input is a string that contains the JSON input data for the execution and gives the following example: "input": "{\"ami_id\" : \"ami_id\"}". My question is how do I pass the variables in question to this parameter as the value? My code is below with the traceback:

You can add the value of the variable to the string like this:
input="{\"ami_id\": \"" + ami_id + "\", \"source_account_id\": \"112233445566\", \"accountList\": accountList, \"kms_key_arn\": \"alias/aws/ebs\"}"
Your code currently sends the literal string "ami_id", instead of the variable value of ami_id
I am trying to link my django web app to Azure ML API. I do have Django form with all the required inputs for my Azure API.

if form.is_valid():
age = form.cleaned_data['age']
bmi = form.cleaned_data['bmi']
args = {"age":age,"bmi":bmi}
json_data = str.encode(json.dumps(args))
print(type(json_data))
r= urllib.request.Request(url,json_data,headers)
try:

print(json_data)

return render(request,self.template_name)
When i try to submit the form i am getting type error -
TypeError('POST data should be bytes, an iterable of bytes, or a file object. It cannot be of type str.',)
Getting status code - 400 and below error
{'error': {'code': 'BadArgument', 'message': 'Invalid argument provided.', 'details': [{'code': 'RequestBodyInvalid', 'message': 'No request body provided or error in deserializing the request body.'}]}}
Arguments are using print(json_data) -
b'{"age": 0, "bmi": 22.0}'
Can someone help me on this?
Try to use JsonResponse:
https://docs.djangoproject.com/en/2.1/ref/request-response/#jsonresponse-objects
Also, I don't think you need a template for API response.
return JsonResponse({'foo': 'bar'})
Thanks all. I found the error it was the data which was not in proper order.
I am new to Azure Cognitive Services. I am using python 3.5 and the Azure Face service, specifically the "Face - Find Similar" API. I am getting an error formatting the Post JSON body. The documentation says that I should either provide a single faceId or a list of faces in a face list, e.g., 'extended_family'. In my case, I want to use the face list. I do not know how to format the faceID parameter in the JSON so that call processes the face list. I have tried different alternatives to setting faceId to '{}' or 'Null', '', 'False', and this results in errors.
Below is my JSON body for my POST:
{'faceId': '97522b8b-02b6-4115-99e0-6dc1f5d45f51', 'faceIds': ['97522b8b- 02b6-4115-99e0-6dc1f5d45f51', '0ca8f3e4-edf1-4c14-b926-3b47eae7e29c', '2fadbb12-b10b-4761-aaaa-c50f1dc765c3', '56f464d5-b388-4fc7-9051-6991cf5f1d0d', '29931480-632e-40b6-aa0c-9e03e36e95f9', '7a8085b2-2013-4742-a51a-a5543a0347e8'], 'faceListId': 'extended_family', 'maxNumOfCandidatesReturned': 20, 'mode': 'matchPerson'}
Since faceId is populated, I get:
error: 'code': 'BadArgument', 'message': 'Argument faceListId and faceIds cannot be provided at the same time.'
If I leave faceId blank, such as:
{'faceId': '', 'faceIds': ['824e3d83-a94f-4ef2-949e-55a55b2ef256', '51f3c1a5-4e16-4b14-89fa-f1342a2c46ec', '0480d2e0-ff05-44de-b3d8-94408277b1c5', 'c7d767fb-0fbe-46c8-b7af-2c8f675bfd8d', 'ca7e82a7-cd3f-417b-bffa-77c9d47c1439', 'f7130e90-9e1f-428a-a773-93c87932a420'], 'faceListId': 'extended_family', 'maxNumOfCandidatesReturned': 20, 'mode': 'matchPerson'}
I get the following:
{'error': {'code': 'BadArgument', 'message': 'Request body is invalid.'}}
If I remove the faceId term from the JSON:
{'faceIds': ['690feffd-5c86-47d7-ac3c-224b0eafa90f', '936564e0-31aa-43e3-916e-c7b236bea8e0', '614c04cb-4375-44c8-b393-89d64b4c1ebd', 'a29f8e5c-50ba-4bb8-8bf8-98e356a9125a', '073d7865-2aaf-4806-9bef-ddca478137ea', '7e416e83-5973-4aa1-b1fc-3a25b5174bb3'], 'faceListId': 'andersen_extended_family', 'maxNumOfCandidatesReturned': 20, 'mode': 'matchPerson'}
{'error': {'code': 'BadArgument', 'message': 'Face ID is invalid.'}}
My code is as follows:
facelist = list() #This is populated upstream using the Face Detect API
facelistid = 'extended_family'
faceid = ''
payload = {'faceId': faceid, 'faceIds':facelist,'faceListId':facelistid, 'maxNumOfCandidatesReturned':20,'mode': "matchPerson"}
req = requests.post(serviceurlpersongroup, data = json.dumps(payload) , headers = {'Ocp-Apim-Subscription-Key': key})
jinfo = req.json()
Just as the error message explained, faceListId and faceIds (not faceId) should not be provided at the same time. So the payload you use should be
payload = {'faceId': faceid, 'faceListId': facelistid, 'maxNumOfCandidatesReturned': 20, 'mode': "matchPerson"}
or
payload = {'faceId': faceid, 'faceIds': facelist, 'maxNumOfCandidatesReturned': 20, 'mode': "matchPerson"}
Feel free to update if you have any further questions.
I use rest API on Ruby with sinatra.
I got payment information from IAMPORT,,,
def get_authrestapi()
#key = IMP_KEY
#secret = IMP_SECRET
response = RestClient.post 'https://api.iamport.kr/users/getToken', {'imp_key' => #key, 'imp_secret' => #secret}, :accept => :json
json = JSON.parse(response.to_json, symbolize_names: true)
return json['response']['access_token']
end
but, I got error message... like below
JSON::ParserError at /payments 757: unexpected token at '"{\"code\":0,\"message\":null,\"response\":{\"access_token\":\"9898....", "..."}}"'
How can I solve this problem?? I think,, there is problem that variable 'json' is not HASH..
Thanks.
Don't convert the response to json. It's already json.
Replace the following line:
json = JSON.parse(response.to_json, symbolize_names: true)
with:
json = JSON.parse(response, symbolize_names: true)
