Hi evry1,

I'm currently playing with some web services, and have a bunch of questions :

- Is it possible to send GET/POST HTTP/HTTPS requests using core (+provided library) processing ?

- If yes, any simple example ?

- If no, what would be another option? (go for pure java, find a library around that does all the job and wrap it with processing?).

I made research on discourse, looked at processing hacks but could not find a presice answer to my problem.

Thanks lot by advance,

Thx for the quick answer !

I try to implement one of the google authentification api within processing: Either OAuth or ClientLogin – from scratch. ClientLogin seems simpler for a start, so i choosed this one.

I know that google already provide java client library that i could import to simplify the hard work.

Making it from scrath simply help me to understand how does that work as it for learning purpose.

So i'd like to send the HTTP requests from processing and handle XML received from google's servers.

I tried with the standard Network library to connect to google but got that error :

java.net.UnknownHostException: www.google.com
     at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:177)
     at java.net.SocksSocketImpl.connect(SocksSocketImpl.java:366)
     at java.net.Socket.connect(Socket.java:525)
     at java.net.Socket.connect(Socket.java:475)
     at java.net.Socket.<init>(Socket.java:372)
     at java.net.Socket.<init>(Socket.java:186)
     at processing.net.Client.<init>(Unknown Source)
     at GoogleTest.setup(GoogleTest.java:64)
     at processing.core.PApplet.handleDraw(Unknown Source)
     at processing.core.PApplet.run(Unknown Source)


I'm at work so behind a proxy server, but i used Properties class to set up the http server and i can load images from the internet with success.

Is tried to connect using port 80 and 443 without success.
The line dropping the error is :

Code:

 c = new Client(this,"www.google.com",80); 

Hope that help to understand my problem.
Regards.

Many thanks for the help provided PhiLho,

I tried my code at home and it does work !

So the main problem i'm facing now, is calling the google API behind a proxy server.

How can i fetch a remote ressource behing a proxy ?

I've used System.setProperty method to set the http proxy and it does work.

But i do suppose that client use a network socket that's why the host name isn't resolved.

Does someone have any idea ? (even if needs some java code).

Regards,
