I have a Unity project making API calls to sites like Patreon and other video streaming websites no problem, but when I use the same method to use YouTube v3 API, it doesn't seem to recognize the access token I am passing to the endpoint.
// MyYouTubeAPI.cs
[Serializable]
struct formData
{
public string part;
public string broadcastType;
public string mine;
public string key;
}
void Start()
{
StartCoroutine(GetLatestLiveChatID());
}
IEnumerator GetLatestLiveChatID()
{
// create instance of our class with our values
formData data = new formData
{
part = "snippet,contentDetails,status",
broadcastType = "all",
mine = "true",
key = apiKey
};
// convert our class to json
string JsonData = JsonUtility.ToJson(data);
// instance of unity web request
UnityWebRequest www = UnityWebRequest.Post("https://youtube.googleapis.com/youtube/v3/liveBroadcasts", "GET");
// setup upload/download headers (this is what sets the json body)
byte[] bodyRaw = Encoding.UTF8.GetBytes(JsonData);
www.uploadHandler = (UploadHandler)new UploadHandlerRaw(bodyRaw);
www.downloadHandler = (DownloadHandler)new DownloadHandlerBuffer();
// set your headers
www.SetRequestHeader("Authorization", "Bearer " accessToken); // MY ACCESS TOKEN ACTUALLY IS VALID THOUGH
www.SetRequestHeader("Content-Type", "application/json");
yield return www.SendWebRequest();
if (www.isNetworkError || www.isHttpError)
{
Debug.Log(www.error);
Debug.Log(www.downloadHandler.text); // I GET THESE ERRORS IN UNITY CONSOLE
}
else
{
// Debug.Log(www.downloadHandler.text);
jsonString = www.downloadHandler.text;
Debug.Log(jsonString);
}
}
However I get the following error inside the Unity console:
{
"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.",
"errors": [
{
"message": "Invalid Credentials",
"domain": "global",
"reason": "authError",
"location": "Authorization",
"locationType": "header"
}
],
"status": "UNAUTHENTICATED"
}
}
My access token is completely valid, because I get the following when checking its status
{
"issued_to": [MY CLIENT ID],
"audience": [MY CLIENT ID],
"scope": "https://www.googleapis.com/auth/youtube.force-ssl",
"expires_in": 3586,
"access_type": "offline"
}
Sorry for my formatting, I don't post much here. Would anyone have any clue why I am running into this problem? I can't for the life of me figure out why my access token isn't being seen or recognized or passed through. But I am at my wits end. Thank you so much for anyone's help!
CodePudding user response:
If you have access to a bash
prompt (or Windows command prompt for that matter), then try the following command:
curl "https://youtube.googleapis.com/youtube/v3/liveBroadcasts?part=snippet,contentDetails,status&broadcastType=all&mine=true&access_token=YOUR_ACCESS_TOKEN"
.
Also try adding the access token to your composed URL: add access_token: accessToken
to your formData
data
and remove the call to www.SetRequestHeader
.
I suspect though that your variable accessToken
is null
or empty.
