I try to make an authenticated HTTP GET request but I get a 401 HTTP error. I am sure that the signature is right. Because of that, I think the problem is in the multiple headers on line 18. But I can't find the exact problem unfortunately.
Warning: file_get_contents(http://test.com/path): failed to open stream: HTTP request failed! HTTP/1.1 401 Unauthorized in /home/host/path.php on line 22
<?php
$apiKey = '1';
$apiSecret = '2';
$verb = 'GET';
$path = '/path';
$nonce = '1';
$data = '';
$signature = hash_hmac('sha256', $verb . $path . $nonce . $data, $apiSecret);
$url="http://test.com/path";
$opts = [
"http" => [
"method" => $verb,
"header" => "api-nonce: ".$nonce. "\r\n", "api-key: " .$apiKey. "\r\n", "api-signature: " . $signature
]
];
$context = stream_context_create($opts);
$json = file_get_contents($url, false, $context);
if($json){
$data = #json_decode($json, TRUE);
print_r($data);
}
?>
You had a wrong format on line 18.
You used commas to seperate the headers, instead you should just concatenate them as one string:
"header" => "api-nonce: ".$nonce. "\r\n" . "api-key: " .$apiKey. "\r\n" . "api-signature: " . $signature . "\r\n"

Can anybody help me to rewrite the following request in curl or anything similar which is available in php 5.6? I'm new with http request in PHP and I'm not able to use the HttpRequest class cause it can't be found on the server. Other suggestions are welcome too. Maybe there is already a library?
$path = "content/images/calendarmotiv/";
$fail = true;
$tmp = $_FILES['imagetarget']['tmp_name'];
$name = basename($_FILES['imagetarget']['name']);
if(move_uploaded_file($tmp, $path.$name))
{
// http request body
$now = new DateTime('NOW');
$body = json_encode(array(
"name" => $name,
"width" => 1024.0,
"image_url" => base64_encode($path.$name),
"active_flag" => 1,
"application_metadata_url" => base64_encode($_POST["metadata"]))
);
$http_verb = "POST";
$content_md5 = md5($body);
$content_type = "application/json";
$date = str_replace("+0000", "GMT", $now->format(DateTime::RFC1123));
$request_path = "<a href='https://vws.vuforia.com/targets'> https://vws.vuforia.com/targets</a>";
// auth string for header
$string_to_sign = $http_verb . "\n" . $content_md5 . "\n" . $content_type . "\n" . $date . "\n" . $request_path;
$secret_key = "mykey";
$signature = hash_hmac("sha1", $string_to_sign, $secret_key);
$authstring = "VWS " . $secret_key . ":" . $signature;
// the request
$request = new HttpRequest($request_path, HttpRequest::METH_POST);
$request->setContentType($content_type);
$request->setBody($body);
$request->addHeaders(array(
"Date" => $date,
"Authorization" => $authstring));
$request->send();
echo $request->getRequestMessage();
echo $request->getResponseMessage();

As per the new oauth 2.0 for linkedin.
I am unable to get user profile details.
I have set the attributes in my app but still cant get the details.
Can somebody help me the code snippet to get user details.
public function fetch($method, $resource, $body = '') {
$opts = array(
'http' => array(
'method' => $method,
'header' => "Authorization: Bearer " .
$_SESSION['oauth_access_token'] . "\r\n" .

$url = 'api.linkedin.com' . $resource;
if (count($this->$params)) {
$url .= '?' . http_build_query($this->$params);
}
$context = stream_context_create($opts);

return json_decode($response);
}
$xml_response = $LinkedInn->fetch("GET","/v1/people/~");

i'm using the following php to connect to bing api:
how can i add filter (Size:Small)?
the code is from bing documentation and it works fine.
i'm using this code to connect to bing and redirect the response to an iOS app.
please help...
<?php
{
$accountKey = ‘XXXXXXXXX’;
$auth = base64_encode("$accountKey:$accountKey");
$data = array(
'http' => array(
'request_fulluri' => true,
'ignore_errors' => true,
'header' => "Authorization: Basic " . $auth));
$context = stream_context_create($data);
$query = isset($_GET['q']) ? $_GET['q'] : htmlspecialchars($_GET["searchtext"]);
$serviceOp = isset($_GET['sop']) ? $_GET['sop'] : 'Web';
$market = isset($_GET['market']) ? $_GET['market'] : 'en-us';
$ServiceRootURL = 'https://api.datamarket.azure.com/Bing/Search/';
$WebSearchURL = $ServiceRootURL . 'Image?$format=json&Image.Filters=+filterui:imagesize-large+filterui:photo-photo+filterui:face-face&Query=';
$request = $WebSearchURL . urlencode( '\'' . $query. '\'') ;
// Get the response from Bing.
$response = file_get_contents($request, 0, $context);
$jsonobj = json_decode($response);
// echo('<ul ID="resultList">');
header('Content-Type: application/json');
echo($response);
?>
First remove all image filters from $WebSearchURL variable,
and then add your image filters with this way:
$request = $WebSearchURL . urlencode( '\'' . $query. '\'').'&ImageFilters=';
$request = $request . urlencode( '\'' .'Size:Large+Face:Face'. '\'');
Hope it works with you :)
I'm trying to rewrite an fopen() POST request to work with a proxy.
The code is based on an example on the Paypal site (https://www.x.com/developers/PayPal/documentation-tools/code-sample/216632).
My default workarounds for fopen() as well as for file_get_contents() and cURL lib don't work for the relatively complex post header and contents. (Either fail to go through proxy or get Invalid request: {0}, even when no proxy is set)
Here's the (simplified) post example code:
$url = trim('https://svcs.sandbox.paypal.com/AdaptiveAccounts/AddBankAccount');
$API_UserName = "sbapi_1287090601_biz_api1.paypal.com"; //TODO
$API_Password = "1287090610"; //TODO
$API_Signature = "ANFgtzcGWolmjcm5vfrf07xVQ6B9AsoDvVryVxEQqezY85hChCfdBMvY"; //TODO
$API_SANDBOX_EMAIL_ADDRESS = "rishaque#paypal.com"; //TODO
$API_DEVICE_IPADDRESS = "127.0.0.1"; //TODO
$API_AppID = "APP-80W284485P519543T";
$API_RequestFormat = "XML";
$API_ResponseFormat = "XML";
$xml = simplexml_load_string($xml_str);
$contents = $xml->asXML();
try
{
$params = array("http" => array(
"method" => 'POST',
"content" => $contents,
'header' => 'X-PAYPAL-SECURITY-USERID: ' . $API_UserName ."\r\n" .
'X-PAYPAL-SECURITY-PASSWORD: ' . $API_Password . "\r\n" .
'X-PAYPAL-SECURITY-SIGNATURE: ' . $API_Signature . "\r\n" .
'X-PAYPAL-REQUEST-DATA-FORMAT: ' . $API_RequestFormat . "\r\n" .
'X-PAYPAL-RESPONSE-DATA-FORMAT: ' . $API_ResponseFormat . "\r\n" .
'X-PAYPAL-APPLICATION-ID: ' . $API_AppID . "\r\n" .
'X-PAYPAL-SANDBOX-EMAIL-ADDRESS: ' . $API_SANDBOX_EMAIL_ADDRESS . "\r\n" .
'X-PAYPAL-DEVICE-IPADDRESS: ' . $API_DEVICE_IPADDRESS . "\r\n" ));
$ctx = stream_context_create($params);
$fp = #fopen($url, 'r', false, $ctx); // PROXIFY!
$response = stream_get_contents($fp);
if ($response === false) {
throw new Exception("php error message = " . "$php_errormsg");
}
fclose($fp);
// ... handle the response content ...
}
catch(Exception $e)
{
echo 'Message: ||' .$e->getMessage().'||';
}
?>
My proxy file_get_contents():
if (!empty($_context_params)) {
$http_arr = $_context_params['http'];
$http_arr['proxy'] = $proxy_path;
$http_arr['request_fulluri'] = true;
$_context_params['http'] = $http_arr;
}
else
{
$_context_params = array( 'http' => array( 'proxy' => $proxy_path, 'request_fulluri' => true ) );
}
return file_get_contents( $_url, false, stream_context_create( $_context_params ) );
My proxied fopen:
$parsed_proxy_path = parse_url($proxy_path);
$_proxy_name = $parsed_proxy_path['host'];
$_proxy_port = $parsed_proxy_path['port'];
$proxy_fp = fsockopen( $_proxy_name, $_proxy_port );
if ( !$proxy_fp )
return false;
$parsed_url = parse_url($_url);
$host = $parsed_url['host'];
$request = "GET $_url HTTP/1.0\r\nHost:$host\r\n\r\n";
fputs( $proxy_fp, $request );
return $proxy_fp;
My cURL experiment: (CodeIgniter curl lib takes care of proxy for me)
$http_params = $params['http'];
$this->curl->create($this->cfg->paypal_req_url);
$this->curl->option('header', true);$this->curl->option('verbose', true);
$this->curl->option('useragent', 'cURL/PHP');
$this->curl->http_header($http_params['header']);
$this->curl->http_header("Content-length: ".strlen($contents));
$this->curl->post(array("content"=> $contents));
$res = $this->curl->execute();
Any ideas where to go from here? I'm a bit stuck..
How do I debug the request going out from cURL? Is the request even reproducible with cURL?
Will it work with GET instead of POST?
Is XMLRPC an option?
Note: The example code works for me when not behind a proxy.
Thanks in advance,
Alex
Here's the code I used to get it to work with cURL.
Note: It uses the codeigniter cURL lib by Phil Sturgeon.
Note: I resolved to switching from XML to query string for the contents.
$contents = array(
"actionType"=>"PAY",
"cancelUrl"=>$cancel_url,
"returnUrl"=>$return_url,
"currencyCode"=>$currency,
"sender"=>$sendingmail,
"memo"=>$memo,
"requestEnvelope.errorLanguage"=>$error_lang,
"receiverList.receiver.amount"=>$amount,
"receiverList.receiver.email"=>$receivingmail,
);
if (isset($notification_url)) { $contents["ipnNotificationUrl"]=$notification_url; }
if ($receivingmail == $this->cfg->paypal_email) { $contents["feesPayer"]="SENDER"; }
if ($sendingmail == $this->cfg->paypal_email) { $contents["senderEmail"]=$sendingmail; }
// ------------------------------
// create request and add headers
// ------------------------------
$options = array( "useragent" => "cURL/PHP" );
$this->curl->create($this->cfg->paypal_req_url);
$this->curl->http_header("Content-type", "application/x-www-form-urlencoded");
$this->curl->http_header("X-PAYPAL-SECURITY-USERID", $this->cfg->paypal_user_name);
$this->curl->http_header("X-PAYPAL-SECURITY-SIGNATURE", $this->cfg->paypal_signature);
$this->curl->http_header("X-PAYPAL-SECURITY-PASSWORD", $this->cfg->paypal_password);
$this->curl->http_header("X-PAYPAL-APPLICATION-ID", $this->cfg->paypal_app_id);
$this->curl->http_header("X-PAYPAL-REQUEST-DATA-FORMAT", "NV");
$this->curl->http_header("X-PAYPAL-RESPONSE-DATA-FORMAT", "XML");
$this->curl->post($contents, $options);
$response = $this->curl->execute();
For those stuck with PHP4 it might be useful answering the original question of getting it to work through proxy with fopen?
Cheers,
Alex
I am able to get access_token for multiple permissions like emails, contacts, docs, etc. using oAuth 2.0. I have access_token
I got contacts using the following code.
$url = 'https://www.google.com/m8/feeds/contacts/default/full?max- results='.$max_results.'&oauth_token='.$access_token;
$response_contacts= curl_get_file_contents($url);
Now i want to get users Emails using this access_token.
i used this url . but it gives 401 unauthorized Error
$url = 'https://mail.google.com/mail/feed/atom&oauth_token='.$access_token;
$response_emails= curl_get_file_contents($url);
please guide me how can i get emails using access_token.
I've seen references to the Gmail feed using oauth_token as a request parameter. However, once I used the OAuth Playground I discovered that you need to pass your OAuth information as an Authorization header, as you'll see below.
<?php
$now = time();
$consumer = ...; // your own value here
$secret = ...; // your own value here
$nonce = ...; // same value you've been using
$algo = "sha1";
$sigmeth = "HMAC-SHA1";
$av = "1.0";
$scope = "https://mail.google.com/mail/feed/atom";
$path = $scope;
$auth = ...; // an object containing outputs of OAuthGetAccessToken
$args = "oauth_consumer_key=" . urlencode($consumer) .
"&oauth_nonce=" . urlencode($nonce) .
"&oauth_signature_method=" . urlencode($sigmeth) .
"&oauth_timestamp=" . urlencode($now) .
"&oauth_token=" . urlencode($auth->oauth_token) .
"&oauth_version=" . urlencode($av);
$base = "GET&" . urlencode($path) . "&" . urlencode($args);
$sig = base64_encode(hash_hmac($algo, $base,
"{$secret}&{$auth->oauth_token_secret}", true));
$url = $path . "?oauth_signature=" . urlencode($sig) . "&" . $args;
// Create a stream
$opts = array(
"http" => array(
"method" => "GET",
"header" => "Authorization: OAuth " .
"oauth_version=\"{$av}\", " .
"oauth_nonce=\"{$nonce}\", " .
"oauth_timestamp=\"{$now}\", " .
"oauth_consumer_key=\"{$consumer}\", " .
"oauth_token=\"{$auth->oauth_token}\", " .
"oauth_signature_method=\"{$sigmeth}\", " .
"oauth_signature=\"{$sig}\"\r\n"
)
);
$context = stream_context_create($opts);
$out = file_get_contents($path, false, $context);
?>
