无法使用 OAuth 2.0 连接网站管理员工具吗？

Question

我设法通过 Oauth 2 与 Analytics 连接，但找不到使用网站管理员工具的方法。 我在以下位置获得了网站管理员工具的“范围”：https://developers.google.com/oauthplayground/

我在这里使用代码： https://code.google.com/p/google-api-php-client/

但我不能工作。如果有人能指导我将不胜感激。

以下代码将有助于通过 Oauth Flow 获取网站管理员工具 API 访问的访问令牌和刷新令牌

确保您在 API 控制台中提到的重定向 Uri 应该与您将在其中放置以下代码的文件名相同。

例如。如果重定向 uri 是：-somesitename.com/google_oauth.php（带有 http:// 或 https://），则应将以下脚本放在：- google_oauth.php（路径：somesitename.com/google_oauth.php（带有http:// 或 https://))

<?php

    $OAuth = array(
        'oauth_uri' => 'https://accounts.google.com/o/oauth2/auth',
        'client_id' => '#clientId',
        'client_secret' => '#clientSecret',
        'access_type' => 'offline',
        'redirect_uri' => 'http://somesite.com/google_oauth.php',   //this url should be same as you had registered in your api console as redirect uri()
        'oauth_token_uri' => 'https://accounts.google.com/o/oauth2/token'

    );
    $token = array(
        'access_token' => '',
        'token_type' => '',
        'expires_in' => '',
        'refresh_token' => ''
    );

    $title = 'No Code';
    $AuthCode = 'Null';

    // see if error parameter exisits
    $error = _get_url_param($_SERVER['REQUEST_URI'], 'error');
    if ($error != NULL)
    {   // this means the user denied api access to GWMTs
        $title = $error;
    }
    else
    {   // does the code parameter exist?
        $AuthCode = _get_url_param($_SERVER['REQUEST_URI'], 'code');
        if ($AuthCode == NULL)
        {   // get authorization code
            $OAuth_request = _formatOAuthReq($OAuth, "https://www.google.com/webmasters/tools/feeds/");

            header('Location: ' . $OAuth_request);
            exit; // the redirect will come back to this page and $code will have a value
        }
        else
        {
            $title = 'Got Authorization Code';
            // now exchange Authorization code for access token and refresh token
            $token_response = _get_auth_token($OAuth, $AuthCode);
            $json_obj = json_decode($token_response);
            $token['access_token'] = $json_obj->access_token;
            $token['token_type'] = $json_obj->token_type;
            $token['expires_in'] = $json_obj->expires_in;
            $token['refresh_token'] = $json_obj->refresh_token;
            echo 'access_token = ' . $json_obj->access_token;
        }
    }

    function _get_auth_token($params, $code)
    {
        $url = $params['oauth_token_uri'];

        $fields = array(
            'code' => $code,
            'client_id' => $params['client_id'],
            'client_secret' => $params['client_secret'],
            'redirect_uri' => $params['redirect_uri'],
            'grant_type' => 'authorization_code'
        );
        $response = _do_post($url, $fields);
        return $response;
    }

    function _do_post($url, $fields)
    {
        $fields_string = '';

        foreach ($fields as $key => $value)
        {
            $fields_string .= $key . '=' . $value . '&';
        }
        $fields_string = rtrim($fields_string, '&');

        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($ch, CURLOPT_POST, count($fields));
        curl_setopt($ch, CURLOPT_POSTFIELDS, $fields_string);
        $response = curl_exec($ch);
        curl_close($ch);

        return $response;
    }

    function _formatOAuthReq($OAuthParams, $scope)
    {
        $uri = $OAuthParams['oauth_uri'];
        $uri .= "?client_id=" . $OAuthParams['client_id'];
        $uri .= "&redirect_uri=" . $OAuthParams['redirect_uri'];
        $uri .= "&scope=" . $scope;
        $uri .= "&response_type=code";
        $uri .= "&access_type=offline";


        return $uri;
    }

    function _get_url_param($url, $name)
    {
        parse_str(parse_url($url, PHP_URL_QUERY), $params);
        return isset($params[$name]) ? $params[$name] : null;
    }

    function _get_refresh_token($params, $code)
    {
        $url = $params['oauth_token_uri'];

        $fields = array(
            'code' => $code,
            'client_id' => $params['client_id'],
            'client_secret' => $params['client_secret'],
            'refresh_token' => $token['refresh_token'],
            'grant_type' => 'refresh_token'
        );
        $response = _do_post($url, $fields);
        return $response;
    }
    ?>

然后您可以使用此令牌查询网站管理员工具 API 以获取数据。

您也可以使用您用于 Oauth 分析访问的相同代码，只需在查询网站管理员工具 API 数据时用于分析的 oauth 代码中将此 url:https://www.googleapis.com/auth/analytics.readonly 替换为 https://www.google.com/webmasters/tools/feeds/。
