I am attempting to write a simple extension for my site's news
interface in PHP. I'm running into a problem with getting the
oauth_token from the server - I am unable to connect. I suspect this
may be an SSL issue, as I am entirely lost on exactly how SSL plays
into this beyond the fact that it is an https connection. The
documentation, as far as I can see, only says "Use SSL" but never
actually says what for.
A simple little debug page I've been using to test things out:
<?php
// Create the keypair
$res=openssl_pkey_new();
// Get private key
openssl_pkey_export($res, $privatekey);
// Get public key
$publickey=openssl_pkey_get_details($res);
$publickey=$publickey["key"];
print "MAKING...";
$TWITTER = new HTTPRequest("https://api.twitter.com/oauth/
request_token/", HTTP_METH_POST) or print ("CANNOT MAKE TWITTER");
print "MADE<br />\n";
print "SETTING UP SSL...";
$TWITTER->setSslOptions(array("ENGINE_DEFAULT" => 1, "PASSWD" =>
$privatekey));
print "SET UP<br />\n";
print "ADDING HEADERS...";
$TWITTER->addHeaders(array("Authorization" => $auth)) or print
("CANNOT ADD HEADERS");
print "ADDED<br />\n";
print "ADDING POST...";
$TWITTER->setRawPostData($post_stuff);
print "ADDED<br />\n";
print "SENDING...";
try {
print $TWITTER->send()->__toString();
}
catch (HttpException $ex) {
print $ex."<br />\n";
}
print "SENT<br />\n";
print "REPLY: ".($TWITTER->getRawResponseMessage() or ("NO
RESPONSE"));
?>
And the resulting output:
Authorization: OAuth oauth_nonce="1b3b21dba5a3cbbc01e756bd7159ed3b",
oauth_callback="[DEBUG_PAGE]", oauth_signature_method="HMAC-SHA1",
oauth_timestamp="1276492389", oauth_consumer_key="[MY_KEY]",

request_token/)' in [FILE]:48 Stack trace: #0 [FILE](56): HttpRequest-

So, this is an issue with connecting to the server, likely because the
server is expecting SSL. But, what am I supposed to be using SSL on?
The documentation at http://dev.twitter.com/auth just says "SSL is
recommended" and nothing more.
Any help would be much appreciated.
