如何存储JSON响应主体的特定数据集？

Question

现在，我只能通过对其进行过滤，从而使结果仅显示1个数据集。

        let id = 2;
        let userId, title, body;
        cy.request({
            method: "GET", 
            url: "https://jsonplaceholder.typicode.com/posts/",
            qs: {
                id: id
            }
        })
        .then((response) => {
            expect(response.status).to.eq(200)
            userId = response.body[0].userId
            id = response.body[0].id
            title = response.body[0].title
            body = response.body[0].body
            cy.log(`userId: ${userId}, id: ${id}, title: ${title}, 
            body: ${body}`)
        })

let body = JSON.parse(response.body);
let userId = body[0].userId;
