在非常简单的Google Adwords PHP应用上获取OAUTH_TOKEN_INVALID

Question

I have tried to create a very simple test on top of Google Adwords PHP Library to create an AdWordsUser and access the Campaigns services.

I have an approved developer token, I have obtained a client_id and client_secret from Google Cloud Console, I have obtained also an access_token and user_token.

I added all this data into my auth.ini file but my app is failing with this error:

Fatal error: Uncaught SoapFault exception: [soap:Server] [AuthenticationError.OAUTH_TOKEN_INVALID @ ; trigger:''] in /home/kaosmic/www/adwords/src/Google/Api/Ads/Common/Lib/AdsSoapClient.php:216 
Stack trace: 
#0 /home/kaosmic/www/adwords/src/Google/Api/Ads/Common/Lib/AdsSoapClient.php(216): SoapClient->__soapCall('get', Array, NULL, Array, Array) 
#1 /home/kaosmic/www/adwords/src/Google/Api/Ads/AdWords/v201309/CampaignService.php(6208): AdsSoapClient->__soapCall('get', Array)

#4 {main} thrown in /home/kaosmic/www/adwords/src/Google/Api/Ads/Common/Lib/AdsSoapClient.php on line 216 

I thought that maybe the token are expired so I regenerated them but it didn't help. Do you have any idea?

Thank you, Anca
