salesforce rest api使用訪問令牌時出現無效會話ID錯誤

Question

我試圖從PHP中使用REST api和CURL檢索salesforce中的數據。

我執行身份驗證請求並收到'instance_url'和'access_token'，但在執行查詢請求後，我收到「INVALID_SESSION_ID」錯誤。

我的認證請求代碼：

function get_sf_auth_data() { 
    $post_data = array(
     'grant_type' => 'password', 
     'client_id' => 'xxxxxxxxxxxxxxxxxxxxxx', //My client id (xxx... for this example) 
     'client_secret' => '111111111111', // My client secret (111... for this example) 
     'username'  => 'my_user_name', 
     'password'  => 'my_user_password' 
    ); 

    $headers = array(
     'Content-type' => 'application/x-www-form-urlencoded;charset=UTF-8' 
    ); 

    $curl = curl_init('https://login.salesforce.com/services/oauth2/token'); 

    curl_setopt($curl, CURLOPT_HTTPHEADER, $headers); 
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true); 
    curl_setopt($curl, CURLOPT_POST, true); 
    curl_setopt($curl, CURLOPT_POSTFIELDS, $post_data); 

    $response = curl_exec($curl); 
    curl_close($curl); 

    // Retrieve and parse response body 
    $sf_access_data = json_decode($response, true); 

    echo '*********' . $sf_response_data['instance_url'] . '********'; 
    echo '*********' . $sf_response_data['access_token'] . '********'; 

    return $sf_access_data; 
} 

我的查詢請求代碼：

function get_user_sfid($sf_access_data, $user_id_number){ 
    $sql = "SELECT Id, Name 
      FROM Account 
      WHERE ID__c = '$user_id_number'"; 

    $url = $sf_access_data['instance_url'] . '/services/data/v20.0/query/?q=' . urlencode($sql); 

    $headers = array(
     'Authorization' => 'OAuth ' . $sf_access_data['access_token'] 
    ); 

    $curl = curl_init($url); 
    curl_setopt($curl, CURLOPT_HEADER, false); 
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true); 
    curl_setopt($curl, CURLOPT_HTTPHEADER, $headers); 

    $json_response = curl_exec($curl); 
    curl_close($curl); 

    var_dump($json_response); // This prints out the response where i got the error 

    $response = json_decode($json_response); 

    return $response['id']; 
} 

對查詢請求的響應爲是：

[{"message":"Session expired or invalid","errorCode":"INVALID_SESSION_ID"}]

我也曾嘗試使用本指南（http://developer.force.com/cookbook/recipe/interact-with-the-forcecom-rest-api-from-php）作爲參考但它使用「authorization_code」身份驗證而不是密碼。

編輯

應用程序有在Salesforce完全訪問權限和兩個版本的API和認證數據是正確的

我找到了解決辦法。

我定義我的頭陣爲：

$headers = array(
    "Authorization" => "OAuth " . $sf_access_data['access_token'] 
); 

當我應該把它定義爲：

$headers = array(
    "Authorization: OAuth " . $sf_access_data['access_token'] 
);
