GET Request Wrapper

Questions & Answers

Howdy folks,

I’m very new to Unity, and struggling with the MonoBehaviour object.

The goal is to create an object such that I can pass in a url, and receive data via GET. Sooo… we ultimately would like something like this:

data = GET.request(“someurl.com”);

To try and accomplish this, I use the WWW object. Now, in order to give the WWW object time to download, we need to have this happening inside a MonoBehaviour Object and yield the results. So I got this, which works:

public class main : MonoBehavior
{
    IEnumerator Start()
    {
        WWW www = new WWW("http://www.someurl.com/blah.php?action=awesome_stuff"); 
        yield return www;
        Debug.Log(www.text);
    }
}

What I really want is this:

 public class main : MonoBehavior
{
    IEnumerator Start()
    {
        GET request = new GET("http://www.someurl.com/blah.php?action=awesome_stuff"); 
        Debug.Log(request.get_data()); // Where get_data() returns the data (which will be text) from the request.   
    }
}

Now I have the main script attached to the single GameObject in the Hierarchy (called root)

Do I need to have the GET script attached to the root GameObject as well? Can I do that dynamically from main?

Ultimately, I need a solution that allows me to easily send GET and POST requests.

Cheers!

Ah, Got it!

My problem was a misunderstanding of how MonoBehaviour and Coroutines worked. The solution is very simple.

In the editor, make an empty GameObject. I named it DB. Then attach the following script to it:

using System; 
using UnityEngine;
using System.Collections; 
using System.Collections.Generic; 
class DB : MonoBehaviour
{	

void Start(){}

    public WWW GET(string url)
    {

    WWW www = new WWW (url);
    StartCoroutine (WaitForRequest (www));
    return www; 
    }

    public WWW POST(string url, Dictionary<string,string> post)
    {
    WWWForm form = new WWWForm();
    foreach(KeyValuePair<String,String> post_arg in post)
    {
       form.AddField(post_arg.Key, post_arg.Value);
    }
        WWW www = new WWW(url, form);

        StartCoroutine(WaitForRequest(www));
    return www; 
    }

    private IEnumerator WaitForRequest(WWW www)
    {
        yield return www;

        // check for errors
        if (www.error == null)
        {
            Debug.Log("WWW Ok!: " + www.text);
        } else {
            Debug.Log("WWW Error: "+ www.error);
        }    
    }
}

Then, in your main script’s start function, you can do this!

private DB db; 
void Start () 
{
    db = GameObject.Find("DB").GetComponentInChildren<DB>();
    results = db.GET("http://www.somesite.com/someAPI.php?someaction=AWESOME");
    Debug.Log(results.text);
}

Haven’t tested the POST requests, but now all the logic is wrapped up! Send HTTP requests to your hearts desire, cheers!
