Fetch Friends profile image from restfb
题
I am using below code to get profile image of friends using Resfb. I get the response too with name id and image. Please some one help me asap on how to get the image from this data.
Code
Connection<User> myFriends = facebookClient.fetchConnection("me/friends", User.class,Parameter.with("fields", "id, name,picture"));
Response
"data":[{"id":"554603591","name":"Arjun Rao","picture":"http:\/\/profile.ak.fbcdn.net\/hprofile-ak-snc4\/211391_554603591_2022493_q.jpg"}"

You can use restfb to parse Json-Objects:
JsonObject obj = new JsonObject(SERVER_RESPONSE);
try {
String pictureURL = obj.getString("picture");
}
catch(JsonException e) {
// key 'picture' not found
e.printStackTrace();
}

Could it be that RestFB isn't up to date in sense how Graph API returns (some objects) inside "data" object?
I managed to work-around with this custom class:
public class DataPictureHolder {
@Facebook("data")
public ProfilePictureSource picture;
}
You know how to parse the response?
If yes, just get the URL of the image, open a URLConnection
and do a getInputStream()
(the code for this is in this SO answer).
With the InputStream
, you can save to a file or send it to the client.
