android - 我如何从 FaceBook 获取好友列表？

Question

我在 Stack Overflow 中看到了很多这样的问题，但它们并没有解决我的问题。我提到了this , this以及文档链接，如 this和 this

我使用 LoginButton 登录我的应用程序。

我可以使用以下代码获取用户(已登录)的姓名、电子邮件等(工作正常):

private FacebookCallback<LoginResult> callback = new FacebookCallback<LoginResult>() {
        @Override
        public void onSuccess(LoginResult loginResult) {
            AccessToken accessToken = loginResult.getAccessToken();
            Profile profile = Profile.getCurrentProfile();
                    GraphRequest request = GraphRequest.newMeRequest(
                    loginResult.getAccessToken(),
                    new GraphRequest.GraphJSONObjectCallback() {
                        @Override
                        public void onCompleted(
                                JSONObject object,
                                GraphResponse response) {
                            // Application code
                            try {

                                email = object.getString("email");
                            } catch (JSONException e) {
                                e.printStackTrace();
                            }
                            Log.e("EMAIL",email);
                            Log.e("GraphResponse", "-------------" + response.toString());
                        }
                    });
            Bundle parameters = new Bundle();
            parameters.putString("fields", "id,link,gender,birthday,email");
            request.setParameters(parameters);
            request.executeAsync();
}

有权限:

loginButton.setReadPermissions("user_friends");
loginButton.registerCallback(callbackManager, callback);

我在 LogCat 中得到了 JSON。但是现在我想获取好友列表，所以我通过查看文档编写了代码，并稍微更改了我的代码如下:

private FacebookCallback<LoginResult> callback = new FacebookCallback<LoginResult>() {
        @Override
        public void onSuccess(LoginResult loginResult) {
            AccessToken accessToken = loginResult.getAccessToken();
            Profile profile = Profile.getCurrentProfile();
            // I saw following code in Documentation 
            new GraphRequest(
                    AccessToken.getCurrentAccessToken(),
                    "/{friendlist-id}",   /* I actually tried ,friend-list-id' , /me/friends' , '/me/taggable_Friends' and many*/
                    null,
                    HttpMethod.GET,
                    new GraphRequest.Callback() {
                        public void onCompleted(GraphResponse response) {
         //    handle the result
                            Log.d("RESPONSE KBT",response.toString());
                        }
                    }
            ).executeAsync();

        }

有权限:

loginButton.setReadPermissions(Arrays.asList("email", "user_friends","read_custom_friendlists"));
loginButton.registerCallback(callbackManager, callback);

我在我的 LogCat 中得到了这个:

RESPONSE KBT﹕ {Response:  responseCode: 404, graphObject: null, error: {HttpStatus: 404, errorCode: 803, errorType: OAuthException, errorMessage: (#803) Some of the aliases you requested do not exist: {friendlist-id}}}

试试这个:

权限:

setReadPermissions(Arrays.asList("public_profile", "email", "user_friends"));

这个变量用于处理你的 friend :

public static List<TaggableFriends> friendListFacebook = new ArrayList<TaggableFriends>();

这个获取好友的方法(在登录类的onSuccess()方法中调用):

public void getFriends()
{
    if(AccessToken.getCurrentAccessToken() != null)
    {
        GraphRequest graphRequest = GraphRequest.newGraphPathRequest(
                AccessToken.getCurrentAccessToken(),
                "me/taggable_friends",
                new GraphRequest.Callback()
                {
                    @Override
                    public void onCompleted(GraphResponse graphResponse)
                    {
                        if(graphResponse != null)
                        {
                            JSONObject jsonObject = graphResponse.getJSONObject();
                            String taggableFriendsJson = jsonObject.toString();
                            Gson gson = new Gson();
                            TaggableFriendsWrapper taggableFriendsWrapper= gson.fromJson(taggableFriendsJson, TaggableFriendsWrapper.class);
                            ArrayList<TaggableFriends> invitableFriends = new ArrayList<TaggableFriends>();
                            invitableFriends = taggableFriendsWrapper.getData();
                            int i;
                            for(i = 0; i < invitableFriends.size(); i++)
                            {
                                try
                                {
                                    friendListFacebook.add(invitableFriends.get(i));
                                }
                                catch(Exception e){}
                            }
                        }else {

                        }

                    }
                }
        );

        Bundle parameters = new Bundle();
        parameters.putInt("limit", 5000); //5000 is maximum number of friends you can have on Facebook

        graphRequest.setParameters(parameters);
        graphRequest.executeAsync();
    }
}

添加这个类:

TaggableFriendsWrapper:

public class TaggableFriendsWrapper {

private ArrayList<TaggableFriends> data;
private Paging paging;

public ArrayList<TaggableFriends> getData() {
return data;
}

public void setData(ArrayList<TaggableFriends> data) {
this.data = data;
}

public Paging getPaging() {
return paging;
}

public void setPaging(Paging paging) {
this.paging = paging;
}

public class Paging {

private Cursors cursors;
public Cursors getCursors() {
    return cursors;
}

public void setCursors(Cursors cursors) {
    this.cursors = cursors;
}
}

public class Cursors {
private String after;
private String before;

public String getAfter() {
    return after;
}
public void setAfter(String after) {
    this.after = after;
}
public String getBefore() {
    return before;
}
public void setBefore(String before) {
    this.before = before;
}

}
}

TaggableFriends:

public class TaggableFriends {

private String id;
private String name;
private Picture picture;

public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}

public Picture getPicture() {
return picture;
}
public void setPicture(Picture picture) {
this.picture = picture;
}

public class Picture {

private Data data;

public Data getData() {
    return data;
}

public void setData(Data data) {
    this.data = data;
}
}

public class Data {

private String url;
private boolean is_sillhouette;

public String getUrl() {
    return url;
}
public void setUrl(String url) {
    this.url = url;
}
public boolean isIs_sillhouette() {
    return is_sillhouette;
}
public void setIs_sillhouette(boolean is_sillhouette) {
    this.is_sillhouette = is_sillhouette;
}
}
}
