[Monorail API Access] Chromium Issues

[nm6...@g.rit.edu]

Hello,

My name is Nuthan Munaiah and I am a PhD student at the Rochester Institute of Technology, Rochester, NY, USA. I am currently working on a research project in which we are using Natural Language Processing (NLP) to analyze code reviews in the Chromium project. As part of this project, we need access to the bug information in the Chromium bug repository to properly categorize code reviews. After reading the Monorail API documentation (https://docs.google.com/document/d/1asuQNC5tAUvKDf9G9G3IxymuhDxnPCn_fSzX2wwcC6M/edit), I understand that you need information on our usage scenarios to allow us to use the API. Here is the information needed as per the documentation:

0. Requirements
===============

I need access to all details of Chromium issues/bugs.

1. Whitelist
============

I have created a Google Service Account that will be used when accessing the API. The specifics of the account are:

"client_email": "chromium...@appspot.gserviceaccount.com"
"client_id": "106604744474102536576"

2. Permission
=============

I need access to the *Chromium* project.

Please let us know if you need more information.

Thank you,
Nuthan Munaiah

Thanks, Nuthan!

Sorry for the extra work, but can you please file a bug with this same information? It's easier for us to keep track of who requested access (and when) that way.

Thanks!

P.S. Where did you find the link to that doc? I recently updated what I thought was the only version of the "API Getting Started" doc to ask folks to file bugs, but I missed that copy of the doc and would like to replace it with the correct one.

Thanks Aaron. I created a new issue (Issue ID 1841) on the Monorail Issue Tracking System.

Here is the sequence of links to get to documentation I cited:

1. Click *documentation* on https://apis-explorer.appspot.com/apis-explorer/?base=https://monorail-prod.appspot.com/_ah/api#p/monorail/v1/

2. Click *One-page getting started* on https://chromium.googlesource.com/infra/infra/+/master/appengine/monorail/doc/api.md

Perfect, thanks! I'll update that link to point at the updated getting started instructions.

Also, thanks for filing the bug. I'll get you whitelisted shortly.

Aaron

Hi Aaron,

I seem to be having trouble accessing the Monorail API using the service account. I get an exception when I attempt to access the API. I have included the source code and the exception below.

I used the source code example from https://chromium.googlesource.com/infra/infra/+/master/appengine/monorail/doc/example.py as the base. Additionally, I read the documentation on using OAuth 2.0 from https://oauth2client.readthedocs.io/en/latest/source/oauth2client.service_account.html#oauth2client.service_account.ServiceAccountCredentials

Code

import apiclient

from httplib2 import Http
from oauth2client.service_account import ServiceAccountCredentials

DISCOVERY_URL = 'https://monorail-prod.appspot.com/_ah/api/discovery/v1/'\
'apis/{api}/{apiVersion}/rest'

if __name__ == '__main__':
scopes = ['https://www.googleapis.com/auth/userinfo.email']
credentials = ServiceAccountCredentials.from_json_keyfile_name(
'project-3e3c2d88d882.json', scopes
)
http = credentials.authorize(Http())
monorail = apiclient.discovery.build(
'monorail', 'v1', discoveryServiceUrl=DISCOVERY_URL, http=http
)
issues = monorail.issues().list(projectId='chromium').execute()
print(issues)

Exception
