UnityWebRequest.timeout

説明

Sets UnityWebRequest to attempt to abort after the number of seconds in timeout have passed.

When a timeout occurs error returns "Request timeout" . No timeout is applied when timeout is set to 0 and this property defaults to 0.
Note: The set timeout may apply to each URL redirect on Android which can result in a longer response.

using UnityEngine;
using System.Collections;
using UnityEngine.Networking;

// Ask the website to deliver an image that is very large.
// Set the download to take more than 1 second.  This causes
// the "request timeout" error message.

public class ExampleScript : MonoBehaviour
{
    void Start()
    {
        StartCoroutine(GetText());
    }

    IEnumerator GetText()
    {
        UnityWebRequest www = UnityWebRequest.Get("https://my-website.com/verylargeimage.jpg");

        // wait up to one second to download the image
        www.timeout = 1;
        yield return www.SendWebRequest();

        if (www.result != UnityWebRequest.Result.Success)
        {
            Debug.Log(www.error);
        }
        else
        {
            Debug.Log("image arrived");
        }
    }
