Unfortunately, App Engine does not support External calls:

An App Engine application cannot:

write to the filesystem. PHP applications can use Google Cloud Storage for storing persistent files. Reading from the filesystem is allowed, and all application files uploaded with the application are available.

open a socket or access another host directly. An application can use the App Engine URL fetch service to make HTTP and HTTPS requests to other hosts on ports 80 and 443, respectively.

respond slowly. A web request to an application must be handled within a few seconds. Processes that take a very long time to respond are terminated to avoid overloading the web server.

make other kinds of system calls.
