我正在尝试在我的代码中导入Google联系人。我已经成功导入了联系人,但问题是,我必须创建一个导入的电子邮件地址数组,我需要将其传递给另一个页面。但是当我尝试创建一个数组时,我得到一个包含SimpleXMLElement Object
的数组。
这是我的代码:
oauth.php:
<?php
$client_id='my-cient-id';
$client_secret='my-client-secret';
$redirect_uri='my-redirect-uri';
$max_results = 100;
$auth_code = $_GET["code"];
function curl_file_get_contents($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,$url);
curl_setopt($curl,CURLOPT_RETURNTRANSFER,TRUE);
curl_setopt($curl,CURLOPT_CONNECTTIMEOUT,5);
curl_setopt($curl, CURLOPT_USERAGENT, $userAgent);
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, TRUE);
curl_setopt($curl, CURLOPT_AUTOREFERER, TRUE);
curl_setopt($curl, CURLOPT_TIMEOUT, 10);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);
$contents = curl_exec($curl);
curl_close($curl);
return $contents;
}
$fields=array(
'code'=> urlencode($auth_code),
'client_id'=> urlencode($client_id),
'client_secret'=> urlencode($client_secret),
'redirect_uri'=> urlencode($redirect_uri),
'grant_type'=> urlencode('authorization_code')
);
$post = '';
foreach($fields as $key=>$value) { $post .= $key.'='.$value.'&'; }
$post = rtrim($post,'&');
$curl = curl_init();
curl_setopt($curl,CURLOPT_URL,'https://accounts.google.com/o/oauth2/token');
curl_setopt($curl,CURLOPT_POST,5);
curl_setopt($curl,CURLOPT_POSTFIELDS,$post);
curl_setopt($curl, CURLOPT_RETURNTRANSFER,TRUE);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER,FALSE);
$result = curl_exec($curl);
curl_close($curl);
$response = json_decode($result);
$accesstoken = $response->access_token;
$url = 'https://www.google.com/m8/feeds/contacts/default/full?max-results='.$max_results.'&oauth_token='.$accesstoken;
$xmlresponse = curl_file_get_contents($url);
if((strlen(stristr($xmlresponse,'Authorization required'))>0) && (strlen(stristr($xmlresponse,'Error '))>0)) //At times you get Authorization error from Google.
{
echo "<h2>OOPS !! Something went wrong. Please try reloading the page.</h2>";
exit();
}
echo "<h3>Email Addresses:</h3>";
$xml = new SimpleXMLElement($xmlresponse);
$xml->registerXPathNamespace('gd', 'http://schemas.google.com/g/2005');
$result = $xml->xpath('//gd:email');
foreach ($result as $title) {
$var=$title->attributes()->address;
echo $var . "<br>"; //here imported contacts is listing properly
$gc[]=array($var); // creates my contacts array
}
print_r($gc); //printing the created array
?>
我的结果是:
Array ( [0] => Array ( [0] => SimpleXMLElement Object ( [0] => email-address1 ) ) [1] => Array ( [0] => SimpleXMLElement Object ( [0] => email-address2 ) ) )
我需要这样:
Array ( ([0] => email-address1 ) ( [1] => email-address2 ) )
任何人都可以建议我如何做到这一点。我被困在这里很多天了。提前致谢
修改
XML响应:
Array ( [0] => SimpleXMLElement Object ( [@attributes] => Array ( [rel] => http://schemas.google.com/g/2005#other [address] => emailaddress1 [primary] => true ) ) [1] => SimpleXMLElement Object ( [@attributes] => Array ( [rel] => http://schemas.google.com/g/2005#other [address] => emailaddress2 [primary] => true ) ) )
我必须将emailaddress
与对php数组的响应分开。!

这里是$xmlresponse
:
email-id 2015-01-07T09:03:23.311Z profile-name email-id Contacts 2 1 100 http://www.google.com/m8/feeds/contacts/email-id/base/6cc9fe478fd427bb 2014-12-30T04:54:29.902Z
email-id
是导入联系人的邮件ID。
答案 0 :(得分:1)
在最后一个foreach循环的第一行,您可以尝试:
$var=(string)$title->attributes()->address;
或:
$var=(string)$title->attributes()->address[0];
来自http://php.net/manual/en/simplexml.examples-basic.php#116435
的一些代码我认为正确列出电子邮件地址的echo语句隐式调用SimpleXMLElement :: _ toString(void)方法(http://php.net/manual/en/simplexmlelement.tostring.php)。因此,要在创建数组时获得相同的结果,可以通过将(字符串)放在变量名称前面来将其强制转换为字符串。
编辑:
您也可以在添加到数组的位置尝试此操作:
$gc[] = $var;
而不是
$gc[] = array($var);
由于第二种方法创建了一个新的数组对象并向其添加了$ var,因此赋值运算符将整个数组添加到$ gc。这可以解释为什么SimpleXMLObject本身就是一个数组。第一种方式('$ gc [] = $ var;')将向数组$ gc添加一个新元素。或者你可以在foreach循环之前初始化$ gc:
$gc = array();
然后在foreach循环中使用:
array_push($gc, $var);
您需要执行两项建议的更改才能获得所需的结果,所以:
foreach ($results as $title) {
$var=(string)$title->attributes()->address;
$gc[] = $var;
