我正在使用 zend gdata 库编写一个 2 Legged OAuth 应用程序（Google Marketplace 应用程序）。我需要获取谷歌联系人。

代码如下。

require_once 'Zend/Oauth/Consumer.php';
$oauthOptions = array(
    'requestScheme' => Zend_Oauth::REQUEST_SCHEME_HEADER,
    'version' => '1.0',
    'signatureMethod' => 'HMAC-SHA1',
    'consumerKey' => $CONSUMER_KEY,
    'consumerSecret' => $CONSUMER_SECRET
);

$consumer = new Zend_Oauth_Consumer($oauthOptions);
$token = new Zend_Oauth_Token_Access();
$httpClient = $token->getHttpClient($oauthOptions);

$url = 'http://www.google.com/m8/feeds/contacts/default/full';

require_once 'Zend/Gdata/Gapps.php';
$gdata = new Zend_Gdata($httpClient);

require_once 'Zend/Gdata/Query.php';
require_once 'Zend/Gdata/Feed.php';
require_once 'Zend/Gdata/App.php';

$query = new Zend_Gdata_Query($url);
try {
    $feed = $gdata->getFeed($query);
} catch(Zend_Gdata_App_Exception $ex){
    print_r($ex->getMessage());
}

我收到以下错误：

Expected response code 200, got 401
Unknown authorization header
Error 401



执行上述代码时发送的 HTTP 标头是：

GET /m8/feeds/contacts/default/full HTTP/1.1
Host: www.google.com
Connection: close
User-Agent: MyCompany-MyApp-1.0 Zend_Framework_Gdata/1.11.0dev
Accept-encoding: identity
Authorization: OAuth realm="",oauth_consumer_key="686518909188.apps.googleusercontent.com",oauth_nonce="fc99e10f42cdb01c7f3ce1ab2775e616",oauth_signature_method="HMAC-SHA1",oauth_timestamp="1316583946",oauth_version="1.0",oauth_signature="hlbTvPExy4r4%2FyY1ddEsy1AJhf4%3D"

收到的 HTTP 响应：

HTTP/1.1 401 Unknown authorization header
Content-Type: text/html; charset=UTF-8

</HTML>


请让我知道我在这里缺少什么。

使用 2-legged OAuth (xoauth) 时，似乎未设置“xoauth_requestor_id”请求参数。

我尝试在传递给 Zend_Gdata_Calendar 构造函数的 HttpClient 对象上设置此查询参数：

$httpClient->setParameterGet('xoauth_requestor_id', $userEmail);

但不幸的是，这种干净的方法不起作用。似乎 Zend_GData_Calendar 类没有充分利用注入的 HttpClient 对象。

所以我求助于扩展 Zend_GData_Calendar 并实例化我的自定义版本。我还没有完全测试所有的功能，但这是我到目前为止所拥有的，它可以很容易地构建：

/**
 * Slightly modified class which extends Zend_Gdata_Calendar. Fixes a problem with the request URI when using 2-legged
 * OAuth (xoauth). Adds on the xoauth_requestor_id query parameter.
 */
class Xoauth_Gdata_Calendar extends Zend_Gdata_Calendar {
    protected $requestorId;

    /**
     * Set the xoauth_requestor_id for requests
     *
     * @param string $requestorId
     */
    public function setRequestorId($requestorId) {
        $this->requestorId = $requestorId;
    }

    /**
     * Get the currently set xoauth_requestor_id
     *
     * @return string
     */
    public function getRequestorId() {
        return $this->requestorId;
    }

    /**
     * {@inheritdoc} extended to also include the xoauth_requestor_id query parameter in the request URI. This fixes
     * an authentication issue when using 2-legged OAuth (xoauth).
     *
     * @return string|Zend_Gdata_App_Feed
     */
    public function getCalendarListFeed() {
        $uri = self::CALENDAR_FEED_URI . '/default';
        if($this->requestorId) {
            $uri .= '?xoauth_requestor_id=' . urlencode($this->requestorId);
        }

        return parent::getFeed($uri,'Zend_Gdata_Calendar_ListFeed');
    }
}

然后使用它来实例化这个类而不是 Zend_Gdata_Calendar 基类。你只需要调用 setRequestorId($usersEmail)，例如：

$calendarClient = new Xoauth_Gdata_Calendar($httpClient);
$calendarClient->setRequestorId($userEmail);

我在尝试访问日历时遇到了同样的问题，非常令人沮丧。我正在使用 Zen (1.11.10) 的最新下载。

require_once 'Zend/Oauth/Consumer.php';
    require_once 'Zend/Gdata/Calendar.php';

    $CONSUMER_KEY = 'mydomain.com';
    $CONSUMER_SECRET = 'mysecret';
    $USER = 'user@mydomain.com';

    $oauthOptions = array(
        'requestScheme' => Zend_Oauth::REQUEST_SCHEME_HEADER,
        'version' => '1.0',
        'signatureMethod' => 'HMAC-SHA1',
        'consumerKey' => $CONSUMER_KEY,
        'consumerSecret' => $CONSUMER_SECRET
    );

    $consumer = new Zend_Oauth_Consumer($oauthOptions);
    $token = new Zend_Oauth_Token_Access();
    $httpClient = $token->getHttpClient($oauthOptions);


    // Create an instance of the Calendar service
    $service = new Zend_Gdata_Calendar($httpClient);

    try {
        $listFeed= $service->getCalendarListFeed();
    } catch (Zend_Gdata_App_Exception $e) {
        echo "Error: " . $e->getMessage();
    }

我已就此事向 Zend 提交了错误报告。参见ZF-11880。请投票支持此错误以尝试提高其优先级。

以下干净的方法不起作用是有原因的

$httpClient->setParameterGet('xoauth_requestor_id', $userEmail);

在 Zend/Gdata/App.php 的第 638 行，它执行以下操作

// Make sure the HTTP client object is 'clean' before making a request
// In addition to standard headers to reset via resetParameters(),
// also reset the Slug and If-Match headers
$this->_httpClient->resetParameters();

因为每次请求都会调用此方法，您在客户端中设置的内容将被删除。

Xoauth_Gdata_Calendar修复有效。
如果你想发布一个事件，你也需要重写这个insertEvent()函数。

/**
 * {@inheritdoc} extended to also include the xoauth_requestor_id query
 * parameter in the request URI. This fixes an authentication issue 
 * when using 2-legged OAuth (xoauth).
 *
 * @return string|Zend_Gdata_Calendar_EventEntry
 */

public function insertEvent($event, $uri=null) {
    if ($uri == null) {
      $uri = $this->_defaultPostUri;
      if($this->requestorId) {
          $uri .= '?xoauth_requestor_id=' . urlencode($this->requestorId);
      }
    }
    return parent::insertEntry($event, $uri, 'Zend_Gdata_Calendar_EventEntry');
}
