How can I display text from a webrequest?

Questions & Answers

I am using a HTTP request to try and access a REST endpoint. I want to display the text I get in a canvas but I can’t seem to get the output of the request to display in the Canvas.

using UnityEngine.Networking;

class Rest_test : MonoBehaviour {
	public TextMesh thistext;
	// Use this for initialization
	void Start () {
		StartCoroutine (GetText ());
	}

	IEnumerator GetText() {
		UnityWebRequest www = UnityWebRequest.Get("http://jsonplaceholder.typicode.com/posts/1");
		www.downloadHandler = new DownloadHandlerBuffer();
		yield return www.Send();

		if(www.isError) {
			Debug.Log(www.error);
		}
		else {
			// Show results as text
			Debug.Log(www.downloadHandler.text);

			// Or retrieve results as binary data
			//byte[] results = www.downloadHandler.data;
		}
	}
	void Update () {
	thistext.text = GetText ();
	}
}

I’m pretty new to C# and Unity so i may be missing something very basic.
I get the following error when I add the script to my scene:
Assets/Rest_test.cs(30,18): error CS0029: Cannot implicitly convert type System.Collections.IEnumerator' to string’

@ccouper

You want to use www.downloadHandler.text and not overwrite the downloadHandler with a new instance. You may also want to use www.SendWebRequest() instead of www.Send()

     IEnumerator GetText() {
         UnityWebRequest www = UnityWebRequest.Get("http://jsonplaceholder.typicode.com/posts/1");

         yield return www.SendWebRequest();
 
         if (www.isError) {
             Debug.Log(www.error);
         } else {
             // Show results as text
             Debug.Log(www.downloadHandler.text);
 
             // Or retrieve results as binary data
             //byte[] results = www.downloadHandler.data;
         }
     }

this is how i usually do it:

using UnityEngine;
using System.Collections;

public class wwww : MonoBehaviour {

	WWW www;
	string txt;
	bool gotit;
	byte[] bytes;

	void Start () {
		www = new WWW("http://jsonplaceholder.typicode.com/posts/1");
	}
	

	void Update () {
				if (!gotit){
	              	if (www.isDone) {gotit=true;
				if(www.error==null){
					bytes=www.bytes;
					txt = www.text;
					print (txt);
					print ("i got "+bytes.Length+" bytes from download");
				}else{print("I got this error: "+www.error);}

			
			}
		}
