An example on using the Github GraphQL API with Python 3

graphql_example.py

# An example to get the remaining rate limit using the Github GraphQL API.

import requests

    request = requests.post('https://api.github.com/graphql', json={'query': query}, headers=headers)
    if request.status_code == 200:
        return request.json()
    else:
        raise Exception("Query failed to run by returning code of {}. {}".format(request.status_code, query))

        
# The GraphQL query (with a few aditional bits included) itself defined as a multi-line string.       
query = """
{
  viewer {
    login
  }
  rateLimit {
    limit
    cost
    remaining
    resetAt
  }
}
"""

result = run_query(query) # Execute the query
remaining_rate_limit = result["data"]["rateLimit"]["remaining"] # Drill down the dictionary
print("Remaining rate limit - {}".format(remaining_rate_limit))

Hey, thanks for this post. Can we enable auto completion or graphiql like features while making these kinds of requests from notebook?

Mutations are the same.

May I mention that the part where it says json={'query': query} does not vary regardless of whether it is a query or mutation. So, yes, it does end up with {"query": { "query"... or {"query": {"mutation":...

👍 amazing thank you...just what I was looking for.

This is just what I needed - thanks!

so cool, exactly what I need, thank you!

Easy to read, flexible and still works in 2021, thanks for this!!!!

thanks!

How do I paginate thru results in python code?

How do I paginate thru results in python code?

Hello!!
Hopefully my solution works for you
I did something like this:

def run_query():  # A simple function to use requests.post to make the API call. Note the json= section.
    end_cursor = ""
    users_list = []
    while True:
        has_next_page = False
        query = """
        {
        organization(login:"[YOUR_ORG]") {
            samlIdentityProvider{
              externalIdentities(first:100""" + end_cursor + """){
                pageInfo {
                          startCursor
                  hasNextPage
                        endCursor
                        }
                nodes{
                  samlIdentity{
                    nameId
                    username
                  }
                  user{
                    login
                    id
                    name
                    email
                  }
                }
              }
            }
          }
        }
        """
        request = requests.post('https://api.github.com/graphql', json={'query': query}, headers=headers)
        if request.status_code == 200:
            result = request.json()
            has_next_page = (result["data"]["organization"]
                                   ['samlIdentityProvider']
                                   ['externalIdentities']['pageInfo']
                                   ['hasNextPage'])
            new_cursor = (result["data"]["organization"]
                                ['samlIdentityProvider']
                                ['externalIdentities']['pageInfo']
                                ['endCursor'])
            result_data = (result["data"]["organization"]
                                 ['samlIdentityProvider']
                                 ['externalIdentities']['nodes'])
            if has_next_page:
                end_cursor = ', after:"' + new_cursor + '"'
            else:
                break
        else:
            raise Exception("Query failed to run by returning code of {}. {}".format(request.status_code, query))
    return

To pass in variables to the query you need to:

• add variables parameter in your run_query function.
• add variables key to the json you that is going to be appended to the graphql endpoint
• create the variables dictionary with the parameters you want to pass

my python is a bit rusty but this works

import requests

class graphQL:

	headers = {"Authorization": "token <token_here>"}

	"""docstring for graphQL"""
	def __init__(self):
		super(graphQL, self).__init__()

	def run_query(self, query, variables): # A simple function to use requests.post to make the API call. Note the json= section.
		request = requests.post('https://api.github.com/graphql', json={'query': query, 'variables': variables}, headers=self.headers)
		if request.status_code == 200:
			return request.json()
		else:
			raise Exception("Query failed to run by returning code of {}. {}".format(request.status_code, query))
	


	def getClosedIssuesActors(self):
		listOfNames = []
		query = '''
			query($owner: String!, $name: String!) { 
				repository(owner: $owner, name: $name){
				  issues(states: CLOSED, first:10){
					edges{
					  node{
						... on Issue{
						  timeline(last: 100){
							edges{
							  node{
								__typename
								... on ClosedEvent{
								  actor{
									login
								  }
								}
							  }
							}
						  }
						}
					  }
					}
				  }
				}
			}'''

		variables = {
  			"owner": "tatmush",
  			"name": "Saturday-THORN-Dev-Rank"
		}	

		result = self.run_query(query, variables) #execute query
		print(result)

don't forget to declare the variables in the query itself.

This approach saved a lot of time for me. thank you for sharing this

query = """
{
  rateLimit {
    limit
    cost
    remaining
    resetAt
  }
}
"""

is not necessary. the ratelimit status is sent in every response.headers

import requests
from datetime import datetime, timezone
import time

github_token = 'ghp_xxxxxxxxxxxxxxxxxxxx'

real_requests_post = requests.post
def wrap_requests_post(*args, **kwargs):
    if not 'headers' in kwargs:
        kwargs['headers'] = {}
    kwargs['headers']['Authorization'] = 'token ' + github_token
    response = real_requests_post(*args, **kwargs)
    if 'x-ratelimit-used' in response.headers._store:
        print("ratelimit status: used %s of %s. next reset in %s minutes" % (
            response.headers['X-RateLimit-Used'],
            response.headers['X-RateLimit-Limit'],
            datetime.fromtimestamp(int(response.headers["X-RateLimit-Reset"]) - time.time(), tz=timezone.utc).strftime("%M:%S")
        ))
    return response
requests.post = wrap_requests_post

query = """
{ viewer { starredRepositories(first: 5) {
    nodes { name nameWithOwner sshUrl description }
    pageInfo { endCursor hasNextPage }
} } }
"""
response = requests.post('https://api.github.com/graphql', json={'query': query})
data = response.json()

sample output

ratelimit status: used 8 of 5000. next reset in 43:57 minutes

For anyone trying to pass variables for these queries, I suggest looking at string.Template in python:

from string Import Template
queryTemplate = Template(
"""{
  viewer {
    repositories(first: $num) {
      pageInfo {
        hasNextPage
        endCursor
      }
      edges {
        node {
          name
        }
      }
    }
  }
}"""
)

query = queryTemplate.substitute(num=n)

This worked well. thx!

Is there a way to search for all issues across an org? Using REST I would do https://api.github.com/search/issues?q=user:{org_name}&per_page=100&page=1 Any help reformatting this for Graphql would be appreciated.

@els-pnw I was trying to find a way of doing it with graphql explorer but got stuck for this error

"message": "Although you appear to have the correct authorization credentials, the kubernetes organization has enabled OAuth App access restrictions, meaning that data access to third-parties is limited. For more information on these restrictions, including how to enable this app, visit https://docs.github.com/articles/restricting-access-to-your-organization-s-data/"

I ended up with something like this

query ($org_name: String!) {
    organization(login: $org_name) {
        repositories(last: 3) {
            nodes {
                issues(last: 2) {
                    nodes {
                        number
                        assignees {
                            edges {
                                node {
                                    name
                                }
                            }
                        }
                        author {
                            login
                        }
                        state
                    }
                }
            }
        }
    }
}

Not sure how much it will help you, again the explorer is nice, just play with it, hope you will get your answer.
