get github issues by their ids through graphql endpoints - github

Question

I am trying to get the list of issues by their ids from Github using graphql, but looks like I am missing something or its not possible.
query ($ids:['517','510']!) {
repository(owner:"owner", name:"repo") {
issues(last:20, states:CLOSED) {
edges {
node {
title
url
body
author{
login
}
labels(first:5) {
edges {
node {
name
}
}
}
}
}
}
}
}
The above query is giving me response as below,
{
"errors": [
{
"message": "Parse error on \"'\" (error) at [1, 14]",
"locations": [
{
"line": 1,
"column": 14
}
]
}
]
}
Kindly help me identify if its possible or that I am doing something wrong here.

You can use aliases in order to build a single request requesting multiple issue object :
{
repository(name: "material-ui", owner: "mui-org") {
issue1: issue(number: 2) {
title
createdAt
}
issue2: issue(number: 3) {
title
createdAt
}
issue3: issue(number: 10) {
title
createdAt
}
}
}
Try it in the explorer
which gives :
{
"data": {
"repository": {
"issue1": {
"title": "Support for ref's on Input component",
"createdAt": "2014-10-15T15:49:13Z"
},
"issue2": {
"title": "Unable to pass onChange event to Input component",
"createdAt": "2014-10-15T16:23:28Z"
},
"issue3": {
"title": "Is it possible for me to make this work if I'm using React version 0.12.0?",
"createdAt": "2014-10-30T14:11:59Z"
}
}
}
}
This request can also be simplified using fragments to prevent repetition:
{
repository(name: "material-ui", owner: "mui-org") {
issue1: issue(number: 2) {
...IssueFragment
}
issue2: issue(number: 3) {
...IssueFragment
}
issue3: issue(number: 10) {
...IssueFragment
}
}
}
fragment IssueFragment on Issue {
title
createdAt
}
The request can be built programmatically, such as in this example python script :
import requests
token = "YOUR_TOKEN"
issueIds = [2,3,10]
repoName = "material-ui"
repoOwner = "mui-org"
query = """
query($name: String!, $owner: String!) {
repository(name: $name, owner: $owner) {
%s
}
}
fragment IssueFragment on Issue {
title
createdAt
}
"""
issueFragments = "".join([
"""
issue%d: issue(number: %d) {
...IssueFragment
}""" % (t,t) for t in issueIds
])
r = requests.post("https://api.github.com/graphql",
headers = {
"Authorization": f"Bearer {token}"
},
json = {
"query": query % issueFragments,
"variables": {
"name": repoName,
"owner": repoOwner
}
}
)
print(r.json()["data"]["repository"])

I don't think you can fetch for issues and pass in an array of integers for their ids.
But you can search for a single issue by id like so (this works for me)
query ($n: Int!) {
repository(owner:"owner", name:"repo-name") {
issue (number: $n) {
state
title
author {
url
}
}
}
}
where $n is {"n": <your_number>} defined.
If you have an array of ids, then you can just make multiple queries to GitHub.
Sadly, with this approach, you cannot specify what the state of the issue to be. But I think the logic is that once you know the issue Id, you shouldn't care what state it is, since you have that exact id.
