Hi.
I would like to be able to parse the content of a website through OF.
But I have no clue how to read the URL content back in to OF.
This is a sample URL:
https://www.videotron.com/api/1.0/internet/usage/wired/123456788.json?lang=en&caller=www.example.de
thx.
at the moment, we haven’t compiled poco with SSL support – but it seems like this would be really helpful as most web services move to https.
it’s on our to-do list for 0071:
https://github.com/openframeworks/openFrameworks/issues/623
some people have been hacking on this, and I know there are versions of poco compiled for SSL support out there.
http://forum.openframeworks.cc/t/https-request-in-of/7457/0
here’s how to do a simple web request, if it’s helpful:
#pragma once
#include "ofMain.h"
class testApp : public ofBaseApp{
public:
void setup();
void update();
void draw();
void keyPressed (int key);
void keyReleased(int key);
void mouseMoved(int x, int y );
void mouseDragged(int x, int y, int button);
void mousePressed(int x, int y, int button);
void mouseReleased(int x, int y, int button);
void windowResized(int w, int h);
void dragEvent(ofDragInfo dragInfo);
void gotMessage(ofMessage msg);
void urlResponse(ofHttpResponse & response);
};
#include "testApp.h"
//--------------------------------------------------------------
void testApp::setup(){
ofRegisterURLNotification(this);
}
void testApp::urlResponse(ofHttpResponse & response){
if(response.status==200 ){
cout << response.request.name << endl;
cout << response.data.getText() << endl;
}else{
cout << response.status << " " << response.error << endl;
}
}
//--------------------------------------------------------------
void testApp::update(){
}
//--------------------------------------------------------------
void testApp::draw(){
}
//--------------------------------------------------------------
void testApp::keyPressed(int key){
ofLoadURLAsync("[http://www.cnn.com","load"](http://www.cnn.com","load"));
}
//--------------------------------------------------------------
void testApp::keyReleased(int key){
}
//--------------------------------------------------------------
void testApp::mouseMoved(int x, int y ){
}
//--------------------------------------------------------------
void testApp::mouseDragged(int x, int y, int button){
}
//--------------------------------------------------------------
void testApp::mousePressed(int x, int y, int button){
}
//--------------------------------------------------------------
void testApp::mouseReleased(int x, int y, int button){
}
//--------------------------------------------------------------
void testApp::windowResized(int w, int h){
}
//--------------------------------------------------------------
void testApp::gotMessage(ofMessage msg){
}
//--------------------------------------------------------------
void testApp::dragEvent(ofDragInfo dragInfo){
}
hope that helps -

depending on what type of data you need back Yahoo Pipes used to be useful for this and may be able to be a proxy for SSL pages
Thanks guys.
Zach’s simple sample gives me this error
OF: OF_LOG_ERROR: ofURLFileLoader Malformed message: Invalid HTTP version string
maybe because the url i am working with is https://www
yes – at the moment, https will not work (because poco is not compiled with SSL support).
you can take a look at the links I provided. also, if you could run php on a server, you could just mirror the content from the https source to http – something like this might work?
<?php
$feed_contents = file_get_contents('[https://example.com/feed.rss'](https://example.com/feed.rss'));
header('Content-Type: application/rss+xml');
echo $feed_contents;
?>
