I've done extensive testing, enabled verbose cURL logging (Leaves no logs, gives a generic cURL error #7), tried using the built in handlers through file_get_contents. (Also errored, see below) It seems no matter what if I attempt to request information from anything on the roblox.com domain from my app it gets errored before it can even try. I know it is not the distant end as multiple other sites are working fine aswell as I've used an alternate host to try the same communications that I'm doing with Google App Engine and it worked without any issue. At this point I can only conclude that Google has banned my app from communicating with the ROBLOX website without giving me any indication of any kind. If this is true, why is my app banned, and more importantly, why wasn't I alerted?
cURL output with verbose logging enabled:
https://api.roblox.com/users/get-by-username?username=christbru01
CURL Failed with error #7:
CURL HTTP CODE #0
CURL INFO: 0
This is the code which generated these:
syslog(LOG_DEBUG,(string)$newurl);
syslog(LOG_WARNING,'CURL Failed with error #'.curl_errno($s).": ".curl_error($s));
syslog(LOG_DEBUG,'CURL HTTP CODE #'.curl_getinfo($s,CURLINFO_HTTP_CODE));
syslog(LOG_DEBUG,'CURL INFO: '.curl_getinfo($s,CURLINFO_HTTP_CONNECTCODE));
file_get_contents output:
file_get_contents(https://api.roblox.com/users/get-by-username?username=Christbru01): failed to open stream: Connection error
This is the code which generated this:
echo file_get_contents("link removed due to insufficient reputation");
You need to enable cURL in your instance by adding google_app_engine.enable_curl_lite = "1" to your php.ini file.
