管理教师和学生

“学生”和“教师”是用户个人资料与课程之间的特定映射，表示用户在课程中的角色。学生和教师身份并非全局性：用户可以在一个课程中被指定为教师，而在另一个课程中被指定为学生。“学生”或“教师”身份代表特定课程中特定用户的一组权限。

学生: Student 资源表示以学生身份注册特定课程的用户。学生可以查看课程详细信息和该课程的教师。
教师: 教师资源表示教授特定课程的用户。教师可以查看和更改课程详情、查看教师和学生，以及管理其他教师和学生。

学生和教师是通过用户的唯一 ID 或电子邮件地址（由 Directory API 返回）进行标识的。当前用户还可以使用 "me" 缩写来引用自己的 ID。

直接添加

网域管理员可以绕过邀请流程，直接将网域内的用户添加为网域内课程的教师或学生。如果课程的所有者位于管理员的网域中，则该课程会被视为位于管理员的网域中。对于经过身份验证的网域管理员网域之外的用户或课程，应用必须使用 invitations.create() 方法发送邀请，以征得用户同意。

添加或移除教师

网域管理员可以使用 teachers.create() 直接将网域内的教师添加到课程中，如以下示例所示：

如果您要代表已通过身份验证的教师添加其他教师，则必须使用 invitations.create() 方法。

您可以使用 teachers.delete() 方法从课程中移除其他教师。这只会将指定教师从课程中移除，不会影响其在其他课程中的授课身份或用户个人资料。

注册或移除学生

网域管理员可以使用 students.create() 方法直接在其网域中添加学生，如以下示例所示：

如果您要代表已通过身份验证的教师添加学生，则必须使用 invitations.create() 方法。

您可以使用 students.delete() 方法从课程中移除学生。这只会将指定学生从课程中移除，不会影响他们在其他课程中的注册或用户个人资料。

检索用户的课程

如需检索学生或教师的课程列表，请调用 courses.list() 并提供相应用户的 studentId 或 teacherId。

检索用户的个人资料

如需检索用户的简要个人资料（包括 ID 和姓名），请使用用户的 ID、电子邮件地址或请求用户的“我”调用 userProfiles.get()。

如需检索 emailAddress 字段，您必须添加 classroom.profile.emails 作用域。

返回的 ID 对应于包含匹配 studentId 或 teacherId 的 Directory API Users 资源。

管理课程所有者

网域管理员可以在教师之间转移课程所有权。如需了解重要详情，请参阅转移课程所有权部分。
