Hi
I am new to FatSecret Platform API and i developed a PHP script to
access food details using foods.search method
Here is the foods.search method Api call example,used Curl and works
perfect.
<?php
$consumer_key = "xxxxxxx";
$secret_key = "xxxxxxx";
//Signature Base String
//<HTTP Method>&<Request URL>&<Normalized Parameters>
$base = rawurlencode("GET")."&";
$base .= "http%3A%2F%2Fplatform.fatsecret.com%2Frest%2Fserver.
api&";
//sort params by abc....necessary to build a correct unique signature
$params = "method=foods.search&";
$params .= "oauth_consumer_key=$consumer_key&"; // ur consumer key
$params .= "oauth_nonce=123&";
$params .= "oauth_signature_method=HMAC-SHA1&";
$params .= "oauth_timestamp=".time()."&";
$params .= "oauth_version=1.0&";
$params .= "search_expression=".urlencode($_GET['pasVar']);
$params2 = rawurlencode($params);
$base .= $params2;
//encrypt it!
$sig= base64_encode(hash_hmac('sha1', $base, "$secret_key&",
true)); // replace xxx with Consumer Secret
//now get the search results and write them down
$url = "http://platform.fatsecret.com/rest/server.api?".
$params."&oauth_signature=".rawurlencode($sig);
//$food_feed = file_get_contents($url);
list($output,$error,$info) = loadFoods($url);
echo '<pre>';
if($error == 0){
if($info['http_code'] == '200')
echo $output;
else
die('Status INFO : '.$info['http_code']);
else
die('Status ERROR : '.$error);
function loadFoods($url)
{
// create curl resource
$ch = curl_init();
// set url
curl_setopt($ch, CURLOPT_URL, $url);
//return the transfer as a string
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
// $output contains the output string
$output = curl_exec($ch);
$error = curl_error($ch);
$info = curl_getinfo($ch);
// close curl resource to free up system resources
curl_close($ch);
return array($output,$error,$info);
?>
the above script working perfect and retrieves food details using
search method.But
when i use food.get method to retrieve data using food_id it says
invalid signature error,Here's the food.get method api call example,I
have given correct keys and passed food_id parameter.Can someone help
me to solve the issue,I am really struck on this code.It says invalid
signature error.
<?php
$consumer_key = "xxxxxxxxx";
$secret_key = "xxxxxxxxxx";
//Signature Base String
//<HTTP Method>&<Request URL>&<Normalized Parameters>
$base = rawurlencode("GET")."&";
$base .= "http%3A%2F%2Fplatform.fatsecret.com%2Frest%2Fserver.api&";
//sort params by abc....necessary to build a correct unique signature
$params = "method=food.get&";
$params .= "oauth_consumer_key=$consumer_key&"; // ur consumer key
$params .= "oauth_nonce=".rand()."&";
$params .= "oauth_signature_method=HMAC-SHA1&";
$params .= "oauth_timestamp=".time()."&";
$params .= "oauth_version=1.0&";
$params .= "food_id=".urlencode($_GET['pasVar']);
$params2 = rawurlencode($params);
$base .= $params2;
//encrypt it!
$sig= base64_encode(hash_hmac('sha1', $base, "$secret_key&",
true)); // replace xxx with Consumer Secret
//now get the search results and write them down
$url = "http://platform.fatsecret.com/rest/server.api?".
$params."&oauth_signature=".rawurlencode($sig);
//$food_feed = file_get_contents($url);
list($output,$error,$info) = loadFoods($url);
echo '<pre>';
if($error == 0){
if($info['http_code'] == '200')
echo $output;
else
die('Status INFO : '.$info['http_code']);
else
die('Status ERROR : '.$error);
function loadFoods($url)
{
// create curl resource
$ch = curl_init();
// set url
curl_setopt($ch, CURLOPT_URL, $url);
//return the transfer as a string
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
// $output contains the output string
$output = curl_exec($ch);
$error = curl_error($ch);
$info = curl_getinfo($ch);
// close curl resource to free up system resources
curl_close($ch);
return array($output,$error,$info);
?>
Help me what's the error in the code and help me to solve the issue as
i have to use this API in my project
