Google API使用access_token获取收件箱电子邮件

Question

使用oAuth 2.0，我可以获得电子邮件、联系人、文档等多种权限的access_token。我有访问权限我使用以下代码获取联系人。

$url = 'https://www.google.com/m8/feeds/contacts/default/full?max-  results='.$max_results.'&oauth_token='.$access_token;
$response_contacts=  curl_get_file_contents($url);

现在我想让用户使用这个access_token发送电子邮件。我用了这个网址。但它给出401 unauthorized Error

$url = 'https://mail.google.com/mail/feed/atom&oauth_token='.$access_token;
$response_emails=  curl_get_file_contents($url);

请指导我如何使用access_token获取电子邮件。

我看到了对使用oauth_token作为请求参数的Gmail提要的引用。然而，当我使用OAuth Playground时，我发现您需要将OAuth信息作为Authorization标头进行传递，如下所示。

<?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}"rn"
  )
);
$context = stream_context_create($opts);
$out = file_get_contents($path, false, $context);
?>
