You most likely will want to take a look at URLLoader:
https://developers.google.com/native-client/dev/peppercpp/classpp_1_1_u_r_l_loader

If you are a packaged app and you want more fine grained control you
can also use libcurl from naclports along TCP permissions in your
webstore manifest.

cheers,
sam

You can see in <ppapi/c/pp_errors.h>, that -1 is PP_OK_COMPLETIONPENDING. This is a valid return result that means that the function will return the result asynchronously in your callback. Your callback will probably return with error, though. This is because of same-origin policy restrictions. Unless the page that is making the request was loaded from the www.google.com origin, your GET request will fail.

For this to work, you need to use Cross-origin Resource Sharing (CORS). This requires support from the server you are communicating with. You also have to call SetAllowCrossOriginRequests on your URLRequestInfo object.

thanks Ben.

Can you help me check the code?

code:

pp::URLRequestInfo request(this);

request.SetAllowCredentials(true);

request.SetAllowCrossOriginRequests(true);

request.SetURL("http://www.google.com.hk");

request.SetMethod("GET");

int32_t resu = urlLoader.Open(request, cc);

The resu is -7 or -11 when application run. I don't know urlloader why so complicated.
