CkoHttpRequest *req = [[CkoHttpRequest alloc] init];

// Loads the HTTP request object from a URL
[req SetFromUrl: @"https://www.youtube.com/watch?v=fAZdTchQePc&t=45s"];

// The verb will be "GET"
NSLog(@"%@%@",@"verb = ",req.HttpVerb);
// The path will be "/watch"
NSLog(@"%@%@",@"path = ",req.Path);

// The output of this loop will be
// 0) v: fAZdTchQePc
// 1) t: 45s
int i;
int numParams = [req.NumParams intValue];
for (i = 0; i <= numParams - 1; i++) {
    NSLog(@"%d%@%@%@%@",i,@") ",[req GetParamName: [NSNumber numberWithInt: i]],@": ",[req GetParamValue: [NSNumber numberWithInt: i]]);
}

// View the request that would be sent if SynchronousRequest is called.
// The HTTP request will be a GET that looks like this:
// 
//     GET /watch?v=fAZdTchQePc&t=45s HTTP/1.1
//     Host: domain
// 
// Note: The HOST header will automatically get filled in with the actual domain when SynchronousRequest is called.

NSLog(@"%@",[req GenerateRequestText]);

// We can add additional params
[req AddParam: @"artist" value: @"Richard Bona"];
[req AddParam: @"musicType" value: @"Jazz"];
[req AddParam: @"festival" value: @"Estival Jazz Lugano"];
[req AddParam: @"year" value: @"2008"];

// Now examine the request that would be sent
// 
//     GET /watch?v=fAZdTchQePc&t=45s&artist=Richard%20Bona&musicType=Jazz&festival=Estival%20Jazz%20Lugano&year=2008 HTTP/1.1
//     Host: domain
// 
NSLog(@"%@",[req GenerateRequestText]);

// We can remove a parameter:
[req RemoveParam: @"t"];
NSLog(@"%@",[req GenerateRequestText]);

// What happens if we change the request from a GET to a POST?
req.HttpVerb = @"POST";
// The request will now look like this:
// 
//    POST /watch HTTP/1.1
//    Host: domain
//    Content-Length: 93
//    
//    v=fAZdTchQePc&artist=Richard%20Bona&musicType=Jazz&festival=Estival%20Jazz%20Lugano&year=2008
// 
NSLog(@"%@",[req GenerateRequestText]);

// What happens if we make it a multipart/form-data?
req.ContentType = @"multipart/form-data";
// Now the POST looks like this:
//    
//    POST /watch HTTP/1.1
//    Content-Type: multipart/form-data; boundary=------------020906020106050705030807
