问题
I am being randomly bugged by the following error message:
This occurs when php library tries to obtain the access token line 112.
Sometimes my code obtains access token in first try, sometimes I need to refresh the URL containing 'code' as get parameter multiple times before access token is obtained.
This error is coming frequently for last 3-4 days.
Fatal error:
Uncaught exception 'apiAuthException' with message 'Error fetching OAuth2 access token, message:
'<HTML> <HEAD> <TITLE>Error processing OAuth 2 request</TITLE> </HEAD>
<BODY BGCOLOR="#FFFFFF" TEXT="#000000">

'' in /google-api-php-client-0.5.0/google-api-php-client/src/auth/apiOAuth2.php:105

The code I use is directly lifted from here (EXACTLY same code with all parameters like app name, secret key, id etc correctly filled). Also, tried registering new app but same error is received.
回答1:
It might be a Google synchronization issue. Check out this Google Groups post and see if you have a similar issue.

I believe this issue is similar to this question on SO. You'll find the solution in the comments of the answer.
To disable at run time, you can use $this->client->setClassConfig("Google_Http_Request", "disable_gzip", true) as well.
This worked great for me.
