Create student roster from Classroom - google-apps-script

Question

I'm trying to pull the student information from a google classroom roster. Here is what I have so far:
function studentRoster() {
var optionalArgs = {
pageSize: 2
};
var getStudents = Classroom.Courses.Students.list("757828465",optionalArgs).students;
Logger.log(getStudents);
}
Sandy's answer below helped solve part of my problem and I get this as a log (names, id's, emails and such changed):
[16-01-05 17:44:04:734 PST] [{profile={photoUrl=https://lh3.googleusercontent.com/-XdUIqdMkCWA/AAAAAAAAAAI/AAAAAAAAAAA/4252rscbv5M/photo.jpg, emailAddress=jsdoe#fjuhsd.org, name={givenName=John, familyName=Doe, fullName=John Doe}, id=108117124004883828162}, courseId=757828465, userId=108117124004883828162}, {profile={photoUrl=https://lh3.googleusercontent.com/-XdUIqdMkCWA/AAAAAAAAAAI/AAAAAAAAAAA/4252rscbv5M/photo.jpg, emailAddress=jhdoe#fjuhsd.org, name={givenName=Jane, familyName=Doe, fullName=Jane Doe}, id=115613162385930536688}, courseId=757828465, userId=115613162385930536688}]
So my question now is: How do I extract only certain pieces of this information (like full name and email)?
The end result will be pushing it to a google sheet.

Answer 1

The Collection sections under the Classroom API Reference can help clarify some of the object chaining required to access the fields you want.
The following code will generate a list of student names, their email, and associated course ID.
function listStudents() {
var optionalArgs = {
pageSize: 0 // Max output
};
var response = Classroom.Courses.Students.list(xxxxxxxxx; // Put CourseID here
var students = response.students;
if(students && students.length > 0){
for( i = 0; i < students.length; i++){
var student = students[i];
// fullName is normally prefixed with s/ use of .substring removes first two characters
Logger.log('%s %s %s', student.profile.name.fullName.substring(2), student.profile.emailAddress, student.courseId );
}
} else {
Logger.log('No students in this course');
}
}
Collection courses.students

The Quickstart example is using the list method, and the list method takes optional query parameters. One of them being pageSize.
Query parameters for List
You are using the get method.
Documentation - Get method
The only options that the get method has is for the Path. And there is only one setting, the id.
So, that object literal named optionalArgs, you don't need for what you are doing. optionalArgs is an object because it has curly braces, and has elements that are "key/value" pairs. It's "literal", because it's typed into the code, as opposed to building the object with code.
If you did a search, (open the search dialog with Ctrl + F), and searched for optionalArgs, you'll see that it's not being used anywhere. So, the optionalArgs object with the pageSize property is not needed when using the get method.
