How to get the user 'contactid' using google API using PHP

问题

I am trying to fetch user contacts with all user details uaing the google API 3.0. I am able to get the JSON response with the details of the user.

$url = 'https://www.google.com/m8/feeds/contacts/default/full?max-results='.$max_results.'&alt=json&v=3.0&oauth_token='.$accesstoken;

The result is

   [entry] => Array
            (
                [0] => Array
                    (

                                [0] => Array
                                    (
                                        [deleted] => false
                                        [href] => http://www.google.com/m8/feeds/groups/sachitaware

                            )

                    )

But here I dont get the contact image of the user.The documentation says I need a contact id for getting the photo,but I dont get a contact id in the response above.How can I get the contact id of the user and subsequently his contact photo?

I have authorized the app using oauth 2.0 and apart from image I get most of the details of the contact.

EDIT: I tried this way from the documentation and it works,but it returns the binary image instead of the image URL and I have to send another request to get the image.

 $url1   ='https://www.google.com/m8/feeds/photos/media/{useremail}/13444?       v=3.0&oauth_token='.$accesstoken;
 $xmlresponse1 =  curl($url1);

To display the image:

 <img src="data:image/*;base64,<?php echo base64_encode($xmlresponse1); ?> />

Can't I get the contact image URL something like facebook returns?

回答1:

According the documentation, contactIid is returned in the contact entry URL returned by the API:

http://www.google.com/m8/feeds/contacts/<userEmail>/base/<contactId>

So, giving your sample:

http://www.google.com/m8/feeds/contacts/sfdhitdf1%40gmail.com/base/1

We have these values:

userEmail: sfdhitdf1@gmail.com
contactId: 1
