11  Volley Requests

Tutorial

• Test sites and responses

  • Note: Room 17 desktops can't access sites.tjhsst.edu sites.  

    • Use weather api like this one at api.open-meteo.com: 

      • https://api.open-meteo.com/v1/forecast?latitude=52.52&longitude=13.41&current=temperature_2m,wind_speed_10m&hourly=temperature_2m,relative_humidity_2m,wind_speed_10m

    • or this one for quote of the day:

      • http://api.quotable.io/random

    • or this example from the tutorial above: 

      • https://reqres.in/api/users?page=2

  • https://mw-demo.sites.tjhsst.edu/ => hello world

  • https://mw-demo.sites.tjhsst.edu/data => 4 by 4 table in JSON form

    • [{"id":0,"category":"cat1","increment":0,"decrement":0},{"id":1,"category":"cat2","increment":24,"decrement":0},{"id":2,"category":"cat3","increment":2,"decrement":0},{"id":4,"category":"cat4","increment":0,"decrement":0}]

    • Notes to format response into array

      • Study this code and modify for the api you choose to use

      • I recommend starting with a StringRequest instead of JsonObjectRequest

  • https://mw-demo.sites.tjhsst.edu/data/add?id=2 => 

    • increments row 3 (vary the id number to increment other  rows)

    • returns category and increment value of the row increased

      • {"category":"cat3","increment":3}
