Hasura API with Python POST gives 404 Error

I'm trying to use the Hasura API to get the contents of my database. The appropriate endpoint is v1alpha1/pg_dump.
I've tried doing the following in Python:
import requests
api_url = 'http://localhost:9695/v1alpha1/pg_dump'
header = {'Content-Type': 'application/json',
'x-hasura-admin-secret': 'MY_SECRET',
'X-Hasura-Role': 'admin'}
r = requests.post(url=api_url, headers=header)
If I do requests.get, I get information back (html code, although nothing particularly useful). However, if I do requests.post (which is required by Hasura: https://hasura.io/docs/1.0/graphql/core/api-reference/pgdump.html), I get a 404 error. I don't understand why. It's not an authentication error, but a page not found error.
Have I built my url incorrectly? Is there something I'm missing? The port is correct (and if I change it in the code, it gives me a different error telling me the port is invalid/closed). I'm not sure what else to change.

So, I have tried in my own Digital Ocean 1 click deployment environment. I have not secured it so I am not providing any headers. It works fine as follows:
import requests
import json
r = requests.post('http://address_of_hasura/v1alpha1/pg_dump',
data = json.dumps({
'opts' : ['-O', '-x', '--schema-only', '--schema', 'public'],
'clean_output': True
}) )
print r.text
If you have used the HASURA_GRAPHQL_ENABLED_APIS env variable and not included pgdump, that could be a reason it would be disabled.

Is it possible to make a POST request to Slack with AWS Lambda using only native libraries?

I am trying to make a POST request to Slack using webhooks. I can send a curl to my Slack instance locally but when trying to do so in lambda I run into trouble trying to send the payload.
Everything I've seen says I must use and zip custom libraries but for the purposes of what I'm doing I need to use native python code. Is there a way to send this POST request?
import json
import urllib.request
#import botocore.requests as requests
def lambda_handler(event, context):
message=event['message']
response = urllib.request.urlopen(message)
print(response)
This code gives me a 400 error which is how I know I'm hitting the URL I want (URL is in the message variable) but every attempt at sending a payload by adding headers and a text body seems to fail.

You may try as below:
SLACK_URL = 'https://hooks.slack.com/services/....'
req = urllib.request.Request(SLACK_URL, json.dumps(message).encode('utf-8'))
response = urllib.request.urlopen(req)

Please find attached lambda_handler code, hope this helps you.
All the messages to be posted on slack are put on a SNS topic which in turn is read by a lambda and posted to the slack channel using the slack webhook url.
import os
import json
from urllib2 import Request, urlopen, URLError, HTTPError
# Get the environment variables
SLACK_WEBHOOK_URL = os.environ['SLACK_WEBHOOK_URL']
SLACK_CHANNEL = os.environ['SLACK_CHANNEL']
SLACK_USER = os.environ['SLACK_USER']
def lambda_handler(event, context):
# Read message posted on SNS Topic
message = json.loads(event['Records'][0]['Sns']['Message'])
# New slack message is created
slack_message = {
'channel': SLACK_CHANNEL,
'username': SLACK_USER,
'text': "%s" % (message)
}
# Post message on SLACK_WEBHOOK_URL
req = Request(SLACK_WEBHOOK_URL, json.dumps(slack_message))
try:
response = urlopen(req)
response.read()
print(slack_message['channel'])
except HTTPError as e:
print(e)
except URLError as e:
print(e)

Python HTTPSConnection encryption and Name or service not found error

I’m trying to connect to the OPS API but get an error when trying to connect to the url. I get the access_token just fine as detailed in the documentation (page 34), but when I try to connect to the url I’m interested in, I get a ‘Name or Service not found’ error.
The documentation states (page 35) that the client should access the OPS resource over an encrypted HTTPS connection, which I think might be the missing step in my code creating this error (or not).
Below is the code I use (replacing #### with my access_token):
from http.client import HTTPSConnection
c = HTTPSConnection('ops.epo.org/3.2/rest-services/published-data/search?q=Automation', port=443)
headers2 = {'Authorization': ‘Bearer ########kv5’}
c.request('GET', '/', headers=headers2)
res = c.getresponse()
data = res.read()
Many thanks.

Not sure why this issue was happening earlier, but it seems to be fine now when I run the following code:
headers = {'Authorization': 'Bearer %s' % token }
query = requests.get('http://ops.epo.org/3.2/rest-services/published-data/search?q=Automation', headers=headers)
query.content
I get a status response code of 200, and I can parse the content just fine.

Iinvalid subscription key when using Microsoft Emotion API for Video in API Testing Console and in Python 2.7

I only manage to use the Emotion API subscription key for pictures but never for videos. It makes no difference whether I use the API Testing Console or try to call the Emotion API by Pathon 2.7. In both cases I get a response status 202 Accepted, however when opening the Operation-Location it says
{ "error": { "code": "Unauthorized", "message": "Access denied due to
invalid subscription key. Make sure you are subscribed to an API you are
trying to call and provide the right key." } }
On the Emotion API explanatory page it says that Response 202 means that
The service has accepted the request and will start the process later.
In the response, there is a "Operation-Location" header. Client side should further query the operation status from the URL specified in this header.
Then there is Response 401, which is exactly what my Operation-Location contains. I do not understand why I'm getting a response 202 which looks like response 401.
I have tried to call the API with Python using at least three code versions that I found on the Internet that
all amount to the same, I found the code here :
Microsoft Emotion API for Python - upload video from memory
python-upload-video-from-memory
import httplib
import urllib
import base64
import json
import pandas as pd
import numpy as np
import requests
_url = 'https://api.projectoxford.ai/emotion/v1.0/recognizeInVideo'
_key = '**********************'
_maxNumRetries = 10
paramsPost = urllib.urlencode({'outputStyle' : 'perFrame', \
'file':'C:/path/to/file/file.mp4'})
headersPost = dict()
headersPost['Ocp-Apim-Subscription-Key'] = _key
headersPost['content-type'] = 'application/octet-stream'
jsonGet = {}
headersGet = dict()
headersGet['Ocp-Apim-Subscription-Key'] = _key
paramsGet = urllib.urlencode({})
responsePost = requests.request('post', _url + "?" + paramsPost, \
data=open('C:/path/to/file/file.mp4','rb').read(), \
headers = headersPost)
print responsePost.status_code
videoIDLocation = responsePost.headers['Operation-Location']
print videoIDLocation
Note that changing _url = 'https://api.projectoxford.ai/emotion/v1.0/recognizeInVideo' to _url =
'https://westus.api.cognitive.microsoft.com/emotion/v1.0/recognizeInVideo' doesn't help.
However, afterwards I wait and run every half an hour:
getResponse = requests.request('get', videoIDLocation, json = jsonGet,\
data = None, headers = headersGet, params = paramsGet)
print json.loads(getResponse.text)['status']
The outcome has been 'Running' for hours and my video is only about half an hour long.
Here is what my Testing Console looks like Testing Console for Emotion API, Emotion Recognition in Video
Here I used another video that is about 5 minutes long and available on the internet. I found the video in a different usage example
https://benheubl.github.io/data%20analysis/fr/
that uses a very similar code, which again gets me a response status 202 Accepted and when opening the Operation-Location the subscription key is wrong
Here the code:
import httplib
import urllib
import base64
import json
import pandas as pd
import numpy as np
import requests
# you have to sign up for an API key, which has some allowances. Check the
API documentation for further details:
_url = 'https://api.projectoxford.ai/emotion/v1.0/recognizeinvideo'
_key = '*********************' #Here you have to paste your
primary key
_maxNumRetries = 10
# URL direction: I hosted this on my domain
urlVideo = 'http://datacandy.co.uk/blog2.mp4'
# Computer Vision parameters
paramsPost = { 'outputStyle' : 'perFrame'}
headersPost = dict()
headersPost['Ocp-Apim-Subscription-Key'] = _key
headersPost['Content-Type'] = 'application/json'
jsonPost = { 'url': urlVideo }
responsePost = requests.request( 'post', _url, json = jsonPost, data = None,
headers = headersPost, params = paramsPost )
if responsePost.status_code == 202: # everything went well!
videoIDLocation = responsePost.headers['Operation-Location']
print videoIDLocation
There are further examples on the internet and they all seem to work but replicating any of them never worked for me. Does anyone have any idea what could be wrong?

The Video Feature of Emotion API retires October 30th, so maybe you should change your procedure to screenshots anyways.
But for your question: The API returns you an URL where your results are accessible. You cannot open this URL in your browser, this will give you the notice of "invalid key", instead you need to call over python again this URL including your key.
I will post you my code how to get the score, I am using Python 3, so there might be some adjustments necessary. Only "tricky" point is getting the Operation ID, which is just the ID in the URL ( =location in my case) which leads to your request. Rest of the parameters like subscription key etc. is as before.
#extract operation ID from location-string
OID = location[67:]
bod = ""
try:
conn =
http.client.HTTPSConnection('westus.api.cognitive.microsoft.com')
conn.request("GET", "/emotion/v1.0/operations/"+OID+"?%s" %params, bod, headers)
response = conn.getresponse()
data = response.read()
print(data)
conn.close()
except Exception as e:
print("[Errno {0}] {1}".format(e.errno, e.strerror))

Did you verify your API call is working using curl? Always prototype calls using curl first. If it works in curl but not in Python, use Fiddler to observe the API request and response.

I also found an answer in the following link, all steps are explained:

How to post to hipchat from python

I have some python tools that I would like to have send updates to a hipchat room. I do this elsewhere with shell scripts, so I know it works in our environment, but I can't seem to get the token pushed to the hipchat API. Gotta be something simple.
First, this authenticates properly and delivers a message:
curl -d "room_id=xxx&from=DummyFrom&message=ThisIsATest&color=green" https://api.hipchat.com/v1/rooms/message?auth_token=yyy
But when I try to use the python "requests" module, I am getting stuck.
import requests
room_id_real="xxx"
auth_token_real="yyy"
payload={"room_id":room_id_real,"from":"DummyFrom","message":"ThisIsATest","color":"green"}
headerdata={"auth_token":auth_token_real,"format":"json"}
r=requests.post("https://api.hipchat.com/v1/rooms/message", params=payload, headers=headerdata)
print r.ok, r.status_code, r.text
Here is my error information:
False 401 {"error":{"code":401,"type":"Unauthorized","message":"Auth token not found. Please see: https:\/\/www.hipchat.com\/docs\/api\/auth"}}
Basically I don't seem to be passing the authentication token in properly. How can I get this working?

In case it helps, here's a working V2 API example. I did find the V2 API to be a bit more sensitive about getting the form of the request exactly right. But, it might be more forward-looking to conform to the V2 API (though the original question seemed to pertain to V1).
#!/usr/bin/env python
import json
from urllib2 import Request, urlopen
V2TOKEN = '--V2 API token goes here--'
ROOMID = --room-id-nr-goes-here--
# API V2, send message to room:
url = 'https://api.hipchat.com/v2/room/%d/notification' % ROOMID
message = "It's a<br><em>trap!</em>"
headers = {
"content-type": "application/json",
"authorization": "Bearer %s" % V2TOKEN}
datastr = json.dumps({
'message': message,
'color': 'yellow',
'message_format': 'html',
'notify': False})
request = Request(url, headers=headers, data=datastr)
uo = urlopen(request)
rawresponse = ''.join(uo)
uo.close()
assert uo.code == 204

Another basic example using requests:
import requests, json
amessage = 'Hello World!'
room = 'https://api.hipchat.com/v2/room/18REPLACE35/notification'
headers = {'Authorization':'Bearer UGetYourOwnAuthKey', 'Content-type':'application/json'}
requests.post(url = room, data = json.dumps({'message':amessage}), headers = headers)

As Ianzz said, try including it in the URL query string. Although clunky (you probably want to hash it!), it definitely works.
The other strange quirk is the tokens that you get through Hipchat; I had no end of problems earlier this evening using my own personal token; it seemed to correspond to v2 beta of the API. If you go in through Group Admin and get a token from there, it may help.
Old question is old.

Here's an official list of libs which use the HipChat API v2 interface
