当我发出以下请求时，Google 只给出错误 503，并不会提供任何有用的信息。

我正在关注这里的文档:https://developers.google.com/android-publisher/v1/purchases/get

最近(自动)刷新了授权 token 。 (通常它会在陈旧时显示 401。)

@imrankhan。以下是在 Perl 中的操作方法:

sub refreshAccessToken {
    my $ua = LWP::UserAgent->new;
    my $req = HTTP::Request->new(POST => 'https://accounts.google.com/o/oauth2/token');
    $req->content_type('application/x-www-form-urlencoded');
    $req->content('grant_type=refresh_token&client_id=9999999.apps.googleusercontent.com&client_secret=xxxxxxxxxxxxxxxx&refresh_token='.$REFRESH_TOKEN);
    # grant_type=refresh_token
    # client_id=<the client ID token created in the APIs Console>
    # client_secret=<the client secret corresponding to the client ID>
    # refresh_token=<the refresh token from the very first authorization step>
    my $res = $ua->request($req);
    if ($res->is_success()) { # parse JSON
        #print $res->content . "\n";
        # {
          # "access_token" : "ya29.AHES3ZQ_MxxxxTeSl530Na2",
          # "token_type" : "Bearer",
          # "expires_in" : 3600,
        # }
        my $json = decode_json($res->content);
        my $accessToken = $json->{'access_token'};
        saveAccessToken($accessToken);
    } else {
        serverError($ERROR_GOOGLE, 'Could not refresh subscription access token from Google server. '.$res->status_line);
        exit;
    }
}
