Question

我正在尝试在Unity项目中使用Google automl对象检测。

以下是Google curl命令示例：

curl -X POST \
  -H "Authorization: Bearer $(gcloud auth application-default print-access-token)" \
  -H "Content-Type: application/json" \
  https://automl.googleapis.com/v1beta1/projects/${PROJECT_ID}/locations/us-central1/models/model-id:predict \
  -d '{
        "payload" : {
          "image": {
            "imageBytes" : "/9j/4AAQSkZJRgABAQAAAQ … "
          },
        }
      }'

经过一番搜索，我开始创建一个UnityWebRequest来测试响应：

WWWForm form = new WWWForm();

        var postUrl = "https://automl.googleapis.com/v1beta1/projects/1043345783500/locations/us-central1/models/IOD1798528344157847552:predict";

        using (UnityWebRequest www = UnityWebRequest.Post(postUrl, form))
        {
            www.SetRequestHeader("Authorization", @"Bearer $(gcloud auth application-default print-access-token)");

            yield return www.SendWebRequest();

            if (www.isNetworkError)
            {
                Debug.Log(www.error);
            }
            else if (www.isDone)
            {
                Debug.Log(www.downloadHandler.text);
            }

        }

所以Google的回复是：

{
  "error": {
    "code": 401,
    "message": "Request had invalid authentication credentials. Expected OAuth 2 access token, login cookie or other valid authentication credential. See https://developers.google.com/identity/sign-in/web/devconsole-project.",
    "status": "UNAUTHENTICATED"
  }
}

我知道，我不是未经身份验证的，但不明白如何进行身份验证。我必须提出认证请求吗？怎么样？我必须发布一些东西以获得访问令牌吗？那我应该寄到哪里呢？

我从Google服务器上下载了一些凭据，但我真的不知道如何使用...

如何在Unity中通过Google Cloud进行身份验证？
