lti-1-3-go-library

Proof of concept golang library for lti 1.3

Based on IMS Global public documentation and PHP reference implementation

Prepare

# assumes the project is at: ${GOPATH}/src/github.com/GRT/lti-1-3-go-library
$ cd ${GOPATH}/src/github.com/GRT/lti-1-3-go-library
# fetch all the dependencies
$ go get ./...

GRT Go Test Platform

Run the tool within the test/reference platform: https://lti-ri.imsglobal.org/platforms/163/

Running the Tool

$ cd ${GOPATH}/src/github.com/GRT/lti-1-3-go-library
$ go run *.go

To perform an LTI 1.3 Tool launch:

• In a browser, go to reference app Platform home (https://lti-ri.imsglobal.org/platforms/163/)
• Click Resource Links
• Click the 'Select User for Launch' button (under 'GRT Go Test Tool Instructor' resource link)
• Choose an existing user and click 'Launch Resource Link (OIDC)'
• Click 'Post Request' (You should see a log entry from the running go app as it handles the OIDC request)
• Click the 'Launch Resource Link' button
• Click the 'Perform Launch' button (on the bottom of the page that shows what the platform will send to the tool).
• The tool launches, returning a page that echoes back much of the launch data from the platform.

From the above point, to exercise the Name and Role Provisioning Services:

• Click on the 'Fetch Members' button
• This should load a couple of new rows to the bottom of the table, including the actual JSON response as well as a table of members

Continuing the example to use the Assignment and Grade Services:

• Choose a user in the 'Member Grading' row
• Enter a grade (0-100) for one of the users and hit the 'Send Grade' Button
• You should see a popup containing the JSON response as well as a new row with the label 'Last Grade Response' that shows the same JSON

Lastly to fetch the grades from the Assignment and Grade Service:

• Push the 'Fetch Grades' Button
• This should load a new row at the bottom of the table that shows both the JSON response of all the grades, and a tabular display of the grades

Note: Deep Linking is not yet implemented in the POC.
