Pada kode Web API yang telah dilihat pada posting-posting sebelumnya akan kita lihat seperti berikut ini :<\/p>\n

Pada contoh kode di atas terdapat 5 method yang akan menjadi API dan terdiri atas 4 kelompok berdasarkan HTTP verb yaitu :<\/p>\n
    \n
  1. GET, dalam penggunaannya method untuk kelompok HTTP verb ini adalah untuk mengambil atau membaca data.  Method pada kelompok ini biasanya mengembalikan suatu keluaran\/output yang kadang bisa disebut sebagai function<\/strong>.<\/li>\n
  2. POST, dalam penggunaannya method untuk kelompok HTTP verb ini adalah untuk membuat (create) item\/resource baru.  Kelompok method ini biasanya tidak mengembalikan keluaran\/output yang kadang disebut procedure<\/strong>.<\/li>\n
  3. PUT, dalam penggunaannya method untuk kelompok HTTP verb ini adalah untuk mengupdate item\/resource yang telah ada. (idem dengan point 2).<\/li>\n
  4. DELETE, dalam penggunaannya method untuk kelompok HTTP verb ini adalah untuk menghapus item\/resource yang telah ada. (idem dengan point 2).<\/li>\n<\/ol>\n
    Pada posting berikutnya akan diterangkan contoh Web API untuk proses CRUD pada database.<\/p>\n","protected":false},"excerpt":{"rendered":"
