Question

(Sorry for my english)

First: I have an application created using C++ (this is for performance needs), this application uses an image to make some processing and returns a simple answer (1 or 0 ).

Now I need to expose this application from a webservice.

I think to create a webservice using Rails, but I don’t know if it’s possible using rails to call the C++ process..

The idea is to use the webservice to get an image sent by a client, pass this image to the C++ application and return (using the webservice) a message to the client, based on the result of C++ application.

Is this possible?

Any example or guideline?

Thanks in advance

EDIT: Solved using Thrift thrift.apache.org

---

I read something about Thrift .. but i think maybe i can’t use to solve this problem (maybe) ..

The idea is use a mobile application (iOS and/or Android) where the user can upload an image to the service. The service take the image and make some image processing, this part (the processing) was written with C++ as standalone application that receive an image and return a message, so when the processing is done, the service receive the result (a message) from the processing app and return this to the mobile application.

So.. is this possible with Thrift (if so, i need to read more)? o i need to use something else?

Thanks in advance

Answer 1

I have never done that before, but I think you should take a look at Thrift which was initially developed by Facebook and allows you to make multiple languages work together via RPC calls.

Thrift allows you to define data types
and service interfaces in a simple
definition file. Taking that file as
input, the compiler generates code to
be used to easily build RPC clients
and servers that communicate
seamlessly across programming
languages.

I encourage you to search on Google with the following keywords : thrift C++ rails webservice etc.
