UnityWebRequest.timeout

描述

设定 UnityWebRequest 在timeout 中指定秒数后尝试中止。

当超时发生时 error 返回“请求超时”。当timeout 被设定为0 时将不应用超时，且该属性默认为0。
注意：设定的超时可能适用于 Android 上的每个 URL 重定向，这会导致更长的响应时间。

// 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()
    {
        using 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.LogError(www.error);
        }
        else
        {
            Debug.Log("image arrived");
        }
    }
