See more HTTP Examples

Demonstrates how to initialize an HTTP request object from a URL. Perl

use chilkat();

$req = chilkat::CkHttpRequest->new();

# Loads the HTTP request object from a URL
$req->SetFromUrl("https://www.youtube.com/watch?v=fAZdTchQePc&t=45s");

# The verb will be "GET"
print "verb = " . $req->httpVerb() . "\r\n";
# The path will be "/watch"
print "path = " . $req->path() . "\r\n";

# The output of this loop will be
# 0) v: fAZdTchQePc
# 1) t: 45s

$numParams = $req->get_NumParams();
for ($i = 0; $i <= $numParams - 1; $i++) {
    print $i . ") " . $req->getParamName($i) . ": " . $req->getParamValue($i) . "\r\n";
}

# View the request that would be sent if HttpSReq 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 HttpSReq is called.

print $req->generateRequestText() . "\r\n";

# We can add additional params
$req->AddParam("artist","Richard Bona");
$req->AddParam("musicType","Jazz");
$req->AddParam("festival","Estival Jazz Lugano");
$req->AddParam("year","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
# 
print $req->generateRequestText() . "\r\n";

# We can remove a parameter:
$req->RemoveParam("t");
print $req->generateRequestText() . "\r\n";

# What happens if we change the request from a GET to a POST?
$req->put_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
# 
print $req->generateRequestText() . "\r\n";

# What happens if we make it a multipart/form-data?
$req->put_ContentType("multipart/form-data");
# Now the POST looks like this:
#    
#    POST /watch HTTP/1.1
#    Content-Type: multipart/form-data; boundary=------------020906020106050705030807
