Untuk apa ?
Dari kode aplikasi Anda, Anda dapat masuk ke portal web mana pun. Ini mungkin diperlukan ketika Anda ingin mengakses sumber daya akun Anda.
Apa yang bisa Anda dapatkan di portal ini?
Anda bisa mendapatkan daftar perjalanan Anda, atau Anda dapat memeriksa perjalanan apa yang direncanakan di seluruh portal dari titik "A" ke titik "B" untuk tanggal tertentu. Anda bisa berbuat lebih banyak.
Apa yang kamu butuhkan?
Server proxy lokal, saya sarankan Fiddler - sederhana dan nyaman
