其中资源表示为链接

where resources are represented as links

这不是事实.链接可能是操作调用，因此它们表示可能的资源状态转换.

This is not true. Links are possibly operations calls, so they are representing possible resource state transitions.

要向集合中添加内容，您需要一个集合资源，并且必须确定要在该集合中存储的内容.在您的情况下，这可能是两件事:团体学生会员身份或学生.如果这是1:n关系，则可以存储学生并删除学生.如果这是n:m关系，则您必须存储成员身份并删除成员身份，因为您不想从存储中删除学生，只需成员身份即可.

To add something to a collection, you need a collection resource and you have to decide what you want to store in that collection. In your case this can be 2 things: group-student memberships or students. If this is an 1:n relation, then you can store students and remove students. If this is an n:m relation then you have to store memberships and remove memberships, since you don't want to remove the students from your storage, just the memberships.

您可以通过两种方式识别成员身份:

You can identify the memberships 2 ways:

• 您可以使用参与者的ID:/groups/1/memberships/student:1或/students/1/memberships/group:1
• 您可以为每个成员资格添加唯一的ID:/memberships/1234

• you can use the ids of the participants: /groups/1/memberships/student:1 or /students/1/memberships/group:1
• you can add a unique id to each membership: /memberships/1234

注释:

• URI结构仅从人的角度来看很重要. REST客户端将检查链接关系，而不是URI结构.
• 资源与数据库中的实体不同.只有通过简单的CRUD应用程序才能代表它们相同的事物.因此，REST与您的数据库结构无关.
