16a-latihan-bikin-https.js

// --- latihan membuat request https ---
// membuat request pada web service menggunakan cURL (client url)
// cURL : merupakan software berbasis CL yg dapat melakukan transaksi data melalui beberapa protoko internet salah satunya adalah https/http
// skenario yang akan dibuat(kasus warung kopi misalkan) adalah:
// 1. request menu kopi
// 2. beli kopi yang available
// 3. beli kopi yang not available

//kode curl berikut :
// curl -X GET https:coffee-api.dicoding.dev/coffees -i

//output:
/**

//penjelasan kode:
// HTTP/1.1 : status line berisi http version
// 200 OK : status kode berhasil (diawali angka 2)
// Content-Type : application/json : file berformat json
// -- skenario 1 sukses --

//selanjutnya kita lakukan skenario 2, memesan menu kopi yang tersedia
// kode berikut :

//curl -X POST -H "Content-Type: application/json" -d "{\"name\": \"Kopi Tubruk\"}" https://coffee-api.dicoding.dev/transactions -i
// output :
/**

 */

// penjelasan kode diatas :
// -X POST : metod POST mengirim rekuest 
// -H "Content-Type: application/json" menetapkan nilai pada header request, memberitahu serber bahwa data terlampir berbentuk json
// -d : parameter data , utk melampirkan data dalam bentuk json
// -- skenario 2 sukses --

// lanjutkan ke skenario terakhir : memesan kopi yang tidak ada (pesan kopi lawak)
// kode berikut :
// curl -X POST -H "Content-Type: application/json" -d "{\"name\": \"Kopi Lawak\"}" https://coffee-api.dicoding.dev/transactions -i
//output :
/**
 * curl -X POST -H "Content-Type: anopi@localhost:~> curl -X POST -H "Content-Type: application/json" -d "{\"name\": \"Kopi Lawak\"}" https://coffee-api.dicoding.dev/transactions -i
