Question

I am using SOAP web-service to grab the gmail inbox. But, it asks me for setting a Google Key for respective API.

How to set up a google key for wsdl? Any Ideas?

I am connecting to the gmail API but, I am not able to get the response into my page.

Code:-

"<div>
<a href='https://accounts.google.com/o/oauth2/auth?client_id=954719584955.apps.googleusercontent.com&redirect_uri=https://localhost/gmail&scope=https://mail.google.com/mail/feed/atom/&response_type=code'> Retrieve your Google Mails using webservices.</a>
</div>"

It redirects to my page which is registered and not getting the google content what I requested.

Code:-

    $client_id='954719584955.apps.googleusercontent.com';
    $client_secret='vyY-DRInNsofJL2MTmpaVRYP';
    $redirect_uri='https://localhost/gmail';
    $max_results = 200;

    $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);   //The URL to fetch. This can also be set when initializing a session with curl_init().
     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_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); //To stop cURL from verifying the peer's certificate.

     $contents = curl_exec($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;

$url = 'https://mail.google.com/mail/feed/atom/??max-results='.$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();
}

Here is the complete code for gmail API.

Please help me out. Thanks.

You should visit google apis console. There you can register an application and set up apis you are going to use.
