Question

我差不多完成了我的php脚本，它将使用OAuth2获取谷歌联系人。我参考了文档@ http://code.google.com/apis/accounts/docs/OAuth2.html

我转储了联系人，我得到了这些：

的字符串（23704） “email@gmail.com2011-06-16T06：52：20.113Zusernameemail@gmail.comContacts127125http：//www.google.com/m8/feeds/contacts/email%40gmail.com/base/02010-01-28T02：12： 46.705Zhttp：//www.google.com/m8/feeds/contacts/email%40gmail.com/base/12010-01-28T02：12：46.705Zhttp：//www.google.com/m8/feeds/contacts/电子邮件％40gmail.com /碱/ 42010-01-28T02：12：46.705Zhttp：//www.google.com/m8/feeds/contacts/email%40gmail.com/base/52010-01-28T02：12：46.705 Zhttp：//www.google.com/m8/feeds/contacts/email%40gmail.com/base/62010-01-28T02：12：46.705Zhttp：//www.google.com/m8/feeds/contacts/email ％40gmail.com /碱/ 72010-01-28T02：12：46.705Zhttp：//www.google.com/m8/feeds/contacts/email%40gmail.com/base/82010-01-28T02：12：46.705Zhttp ：//www.google.com/m8/feeds/contacts/email%40gmail.com/base/92007-08-03T00：28：51.761Zhttp：//www.google.com/m8/feeds/contacts/email% 40gmail.com/base/a2007-08-03T00:28:51.761Zhttp://www.google.com/m8/feeds/contacts/email%40gmail.com/base/b2011-03-27T13:04:13.929Zhttp： //www.google.com/m8/feeds/contacts/ema IL％40gmail.com /碱/ d2007-08-03T00：28：51.761Zhttp：//www.google.com/m8/feeds/contacts/email%40gmail.com/base/e2009-09-22T06：00：55.117 Zhttp：//www.google.com/m8/feeds/contacts/email%40gmail.com/base/f2009-09-22T06：00：55.117Zhttp：//www.google.com/m8/feeds/contacts/email ％40gmail.com /碱/ 102007-08-03T00：28：51.761Zhttp：//www.google.com/m8/feeds/contacts/email%40gmail.com/base/112009-09-22T06：00：55.117Zhttp ：//www.google.com/m8/feeds/contacts/email%40gmail.com/base/122009-09-22T06：00：55.117Zhttp：//www.google.com/m8/feeds/contacts/email% 40gmail.com/base/132009-09-22T06:00:55.117Zhttp://www.google.com/m8/feeds/contacts/email%40gmail.com/base/142007-08-03T00:28:51.761Zhttp： //www.google.com/m8/feeds/contacts/email%40gmail.com/base/172007-08-03T00:28:51.761Zhttp://www.google.com/m8/feeds/contacts/email%40gmail的.com /碱/ 182007-08-03T00：28：51.761Zhttp：//www.google.com/m8/feeds/contacts/email%40gmail.com/base/192007-08-03T00：28：51.761Zhttp：/ /www.google.com/m8/feeds/contacts/email%40gmail.com/base/1f84 bcc8c755f912010-01-28T02：12：46.705Zhttp：//www.google.com/m8/feeds/contacts/email%40gmail.com/base/288c63e8bbcb04d2010-11-07T04：40：15.185Zhttp：//www.google。 COM / M8 /供稿/联系人/电子邮件％40gmail.com /基/ 59573d50dfd5afd2010-10-28T05：29：23.690Zhttp：//www.google.com/m8/feeds/contacts/email%40gmail.com/base/65b55458913d29f2010 -06-07T15：53：28.946Z“

嗯，我应该如何获得联系信息，如电子邮件，姓名等？

以下是代码： oauth_config.php

<?php
define('AUTHORIZATION_ENDPOINT', 'https://accounts.google.com/o/oauth2/auth');
define('ACCESS_TOKEN_ENDPOINT', 'https://accounts.google.com/o/oauth2/token');
define('CLIENT_ID', 'MY CLIENT_ID');
define('CLIENT_SECRET', 'WMY CLIENT_SECRET');
define('CALLBACK_URI', 'http://example.com/oauth2_callback_google.php');

/***************************************************************************

 **************************************************************************/
function runCurl($url, $method = 'GET', $postvals = null) {
    $ch = curl_init($url);

    //GET request: send headers and return data transfer
    if ($method == 'GET'){
        $options = array(
            CURLOPT_URL => $url,
            CURLOPT_RETURNTRANSFER => 1
        );
        $result = curl_setopt_array($ch, $options);
    //POST / PUT request: send post object and return data transfer
    } else {
        $options = array(
            CURLOPT_URL => $url,
            CURLOPT_POST => 1,
            CURLOPT_POSTFIELDS => $postvals,
            CURLOPT_RETURNTRANSFER => 1
        );
        $result = curl_setopt_array($ch, $options);
    }

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

    return $response;
}

/***************************************************************************

function refreshToken($refresh_token) {

    //return JSON refreshed access token object
    return json_decode(runCurl(ACCESS_TOKEN_ENDPOINT, 'POST', $postvals));
}

＆GT;

oauth_index.php

/**
 * This script will be the first to be initiated
 * It will call Google
 */

require_once('oauth2_config.php');

$accessTokenUri = AUTHORIZATION_ENDPOINT
                  ."?client_id=".CLIENT_ID
                  ."&redirect_uri=".CALLBACK_URI
                  ."&scope=https://www.google.com/m8/feeds/"
                  ."&response_type=code";

// Redirect user to Google to get access token
header("Location:".$accessTokenUri);
exit();

oauth_callback_google.php

/**
 * This is the google callback script.
 * After user approves / decline with the Google application,
 * Google will redirect to this script (as define in Google APIs settings)
 */

require_once('oauth2_config.php');

$code = $_GET['code'];
$error = $_GET['error'];

if (isset($error)) {
    exit();
}

if (!isset($code)) {
    exit();
}

//construct POST object for access token fetch request
$post = array('code' => $code,
              'client_id' => CLIENT_ID,
              'client_secret' => CLIENT_SECRET,
              'redirect_uri' => CALLBACK_URI,
              'grant_type' => 'authorization_code',);

//get JSON access token object (with refresh_token parameter)
$token = json_decode(runCurl(ACCESS_TOKEN_ENDPOINT, 'POST', $post));

//set request headers for signed OAuth request
$headers = array("Accept: application/json");

//construct URI to fetch contact information for current user
$contact_url = "https://www.google.com/m8/feeds/contacts/default/full?"
               ."oauth_token=".$token->access_token;

//fetch profile of current user
$contacts = runCurl($contact_url, 'GET', $headers);
var_dump($contacts);

//echo "<h1>REFRESHING TOKEN</h1>";
var_dump(refreshToken($token->refresh_token));

所以运行oauth_index.php。用户批准后，Google会重定向到oauth_callback_google.php，这就是我挂起的地方。

Answer 1

如果其他人碰到这个问题，我会发布答案：

您将获得包含所有信息的完整格式的XML。但是，您的浏览器正在尝试将此XML呈现为HTML。要查看完全返回的XML right-click - > View Source。

最终，您需要将返回的XML传递给XML库并解析它。

Answer 2

 $url = 'https://www.google.com/m8/feeds/contacts/usermail/full?max-results='.$max_results.'&oauth_token='.$accesstoken.'&alt=json&updated-min=2007-03-16T00:00:00';
 function curl_file_get_contents($url)
 {

 $curl = curl_init();
 $userAgent = 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.1.4322)';

 curl_setopt($curl,CURLOPT_URL,$url);   //The URL to fetch. This can also be set when initializing a session with curl_init().
 curl_setopt($curl, CURLOPT_HTTPHEADER,array('GData-Version: 2.0'));
 curl_setopt($curl,CURLOPT_RETURNTRANSFER,TRUE);    //TRUE to return the transfer as a string of the return value of curl_exec() instead of outputting it out directly.
 curl_setopt($curl,CURLOPT_CONNECTTIMEOUT,5);   //The number of seconds to wait while trying to connect.    
 curl_setopt($curl,CURLOPT_HTTPGET,true);
 curl_setopt($curl, CURLOPT_USERAGENT, $userAgent); //The contents of the "User-Agent: " header to be used in a HTTP request.
//curl_setopt($curl, CURLOPT_FOLLOWLOCATION, TRUE); //To follow any "Location: " header that the server sends as part of the HTTP header.
//curl_setopt($curl, CURLOPT_AUTOREFERER, TRUE);    //To automatically set the Referer: field in requests where it follows a Location: redirect.
curl_setopt($curl, CURLOPT_TIMEOUT, 10);    //The maximum number of seconds to allow cURL functions to execute.

// curl_setopt（$ curl，CURLOPT_SSL_VERIFYPEER，FALSE）; //阻止cURL验证对等方的证书。

$ contents = curl_exec（$ curl）;

curl_close($curl);
return $contents;
