    headers)
    export const addBook = (params, headers) => post("/books/book/", params, headers)
    export const editBook = (params, headers) => put("/books/book/", params, headers)
    export const delBook = (params, headers) => del("/books/book/", params, headers)

    1.2 router/index.js 添加路由


    import Books from '@/views/books/Books'
