hotmail get contacts with curl using API - php

Question

function tratar_hotmail(){
$client_id = '0xxxxxxxxxxxxxxxx2';
$client_secret = 'Wyyyyyyyyyyyyyyyyyp';
$redirect_uri = 'http://example.com/';
$auth_code = $_GET["code"];
$fields=array(
'code'=> urlencode($auth_code),
'client_id'=> urlencode($client_id),
'client_secret'=> urlencode($client_secret),
'redirect_uri'=> urlencode($redirect_uri),
'grant_type'=> urlencode('authorization_code')
);
$post = '';
foreach($fields as $key=>$value) { $post .= $key.'='.$value.'&'; }
$post = rtrim($post,'&');
$curl = curl_init();
curl_setopt($curl,CURLOPT_URL,'https://login.live.com/oauth20_token.srf');
curl_setopt($curl,CURLOPT_POST,5);
curl_setopt($curl,CURLOPT_POSTFIELDS,$post);
curl_setopt($curl, CURLOPT_RETURNTRANSFER,TRUE);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER,0);
$result = curl_exec($curl);
curl_close($curl);
$response = json_decode($result);
$accesstoken = $response->access_token;
$url = 'https://apis.live.net/v5.0/me/contacts?access_token='.$accesstoken.'';
$xmlresponse = curl_file_get_contents($url);
echo $xmlresponse;
$xml = json_decode($xmlresponse, true);
foreach($xml['data'] as $emails)
{
echo $emails['name'];
}
}
which outputs:
{ "error": { "code": "request_token_invalid", "message": "The access token isn't valid." } }
How can I get the request_access_token?
-EDIT-
Forgot the curl function
function curl_file_get_contents($url)
{
$curl = curl_init();
$userAgent = 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.1.4322)';
curl_setopt($curl,CURLOPT_URL,$url); //The URL to fetch. This can also be set when initializing a session with curl_init().
curl_setopt($curl,CURLOPT_RETURNTRANSFER,TRUE); //TRUE to return the transfer as a string of the return value of curl_exec() instead of outputting it out directly.
curl_setopt($curl,CURLOPT_CONNECTTIMEOUT,5); //The number of seconds to wait while trying to connect.
curl_setopt($curl, CURLOPT_USERAGENT, $userAgent); //The contents of the "User-Agent: " header to be used in a HTTP request.
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, TRUE); //To follow any "Location: " header that the server sends as part of the HTTP header.
curl_setopt($curl, CURLOPT_AUTOREFERER, TRUE); //To automatically set the Referer: field in requests where it follows a Location: redirect.
curl_setopt($curl, CURLOPT_TIMEOUT, 10); //The maximum number of seconds to allow cURL functions to execute.
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 0); //To stop cURL from verifying the peer's certificate.
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 0);
$contents = curl_exec($curl);
curl_close($curl);
return $contents;
}

Here's a class I've just thrown together for talking to the API:

...and the test script (yes, I am fully aware that my HTML skills are terrible - I don't write very much of it):

All the parts that I think need explanation are commented. If you have any questions let me know.
Note that I haven't extensively tested the class, and it may be lacking when it comes to the more advanced API functionality. Seems to work fairly well for simple contact manipulation though.

Answer 2

In addition to the answer of DaveRandom and the comment of saveATcode: You should submit the redirect url given in $localUrl as a valid redirect url at account live application. They must be exactly the same or else you will get the 'The provided value for the input parameter 'redirect_uri' is not valid....' message. I just mentioned it because mine had a typo and i experienced the same error.
