添加和删除N-N关联的适当REST方法

Question

null

/products/{id}/addcategory/{categoryId}

/products/{id}/removecategory/{categoryId}

Answer 1

POST /products/foo/categories HTTP/1.1
Host: example.org
Content-Type: application/json

{ 
  "categoryId": "bar"
}

HTTP/1.1 201 Created
Location: /products/foo/categories/bar

如果关注幂等性，则可以使用put创建资源，只要资源标识符由客户端提供。我刚才整理的这个答案澄清了这一点。则您的请求如下：

PUT /products/foo/categories/bar HTTP/1.1
Host: example.org
Content-Type: application/json

而成功的响应将与上面所示的大同小异。

若要从给定产品中删除给定类别，可以使用delete请求对/products/{productId}/categories/{categoryId}:

DELETE /products/foo/categories/bar HTTP/1.1
Host: example.org

HTTP/1.1 204 No content
