我正在尝试为我的Android应用添加一项功能,允许用户“签入”其他标记为签到的人。 我有checkins方法没有问题,可以通过添加用户ID作为参数来标记一些(参见下面的代码)
public void postLocationTagged(String msg, String tags, String placeID, Double lat, Double lon) {
Log.d("Tests", "Testing graph API location post");
String access_token = sharedPrefs.getString("access_token", "x");
try {
if (isSession()) {
String response = mFacebook.request("me");
Bundle parameters = new Bundle();
parameters.putString("access_token", access_token);
parameters.putString("place", placeID);
parameters.putString("Message",msg);
JSONObject coordinates = new JSONObject();
coordinates.put("latitude", lat);
coordinates.put("longitude", lon);
parameters.putString("coordinates",coordinates.toString());
parameters.putString("tags", tags);
response = mFacebook.request("me/checkins", parameters, "POST");
Toast display = Toast.makeText(this, "Checkin has been posted to Facebook.", Toast.LENGTH_SHORT);
display.show();
Log.d("Tests", "got response: " + response);
if (response == null || response.equals("") ||
response.equals("false")) {
Log.v("Error", "Blank response");
}
} else {
// no logged in, so relogin
Log.d(TAG, "sessionNOTValid, relogin");
mFacebook.authorize(this, PERMS, new LoginDialogListener());
}
} catch(Exception e) {
e.printStackTrace();
}
}
这很好用(我发布它是为了帮助其他人!),我遇到的问题是我正在尝试创建一个用户朋友列表,以便他们可以选择他们想要的朋友标签。我有方法getFriends(见下文),然后我将用它来生成一个AlertDialog,用户可以从中选择,从而为我提供在上面的“postLocationTagged”方法中使用的id。
public void getFriends(CharSequence[] charFriendsNames,CharSequence[] charFriendsID, ProgressBar progbar) {
pb = progbar;
try {
if (isSession()) {
String access_token = sharedPrefs.getString("access_token", "x");
friends = charFriendsNames;
friendsID = charFriendsID;
Log.d(TAG, "Getting Friends!");
String response = mFacebook.request("me");
Bundle parameters = new Bundle();
parameters.putString("access_token", access_token);
response = mFacebook.request("me/friends", parameters, "POST");
Log.d("Tests", "got response: " + response);
if (response == null || response.equals("") ||
response.equals("false")) {
Log.v("Error", "Blank response");
}
} else {
// no logged in, so relogin
Log.d(TAG, "sessionNOTValid, relogin");
mFacebook.authorize(this, PERMS, new LoginDialogListener());
}
} catch(Exception e) {
e.printStackTrace();
}
}
当我查看日志中的响应时,它会显示:
“得到回应:{”错误“:{”type“:”OAuthException“,”message“:”(#200)权限错误“}}”
我查看了graphAPI文档并搜索了类似的问题,但无济于事!我不确定我是否需要为应用程序请求额外的权限,或者这是你不允许做的事情!任何帮助/建议将不胜感激。

您可能需要以下权限:
检查API文档中的相关内容。在此之前,请确保哪一行导致此权限错误并尝试修复它。

解决方案是在向Facebook图形API发出请求时实现RequestListener。我有新的getFriends()方法(见下文),它使用AsyncGacebookRunner来请求数据。
public void getFriends(CharSequence[] charFriendsNames,String[] sFriendsID, ProgressBar progbar) {
try{
//Pass arrays to store data
friends = charFriendsNames;
friendsID = sFriendsID;
pb = progbar;
Log.d(TAG, "Getting Friends!");
//Create Request with Friends Request Listener
mAsyncRunner.request("me/friends", new FriendsRequestListener());
} catch (Exception e) {
Log.d(TAG, "Exception: " + e.getMessage());
}
}
AsyncFacebookRunner使用实现RequestListener类的自定义FriendsRequestListener(见下文)发出请求;
private class FriendsRequestListener implements RequestListener {
String friendData;
//Method runs when request is complete
public void onComplete(String response, Object state) {
Log.d(TAG, "FriendListRequestONComplete");
//Create a copy of the response so i can be read in the run() method.
friendData = response;
//Create method to run on UI thread
FBConnectActivity.this.runOnUiThread(new Runnable() {
public void run() {
try {
//Parse JSON Data
JSONObject json;
json = Util.parseJson(friendData);
//Get the JSONArry from our response JSONObject
JSONArray friendArray = json.getJSONArray("data");
//Loop through our JSONArray
int friendCount = 0;
String fId, fNm;
JSONObject friend;
for (int i = 0;i<friendArray.length();i++){
//Get a JSONObject from the JSONArray
friend = friendArray.getJSONObject(i);
//Extract the strings from the JSONObject
fId = friend.getString("id");
fNm = friend.getString("name");
//Set the values to our arrays
friendsID[friendCount] = fId;
friends[friendCount] = fNm;
friendCount ++;
Log.d("TEST", "Friend Added: " + fNm);
}
//Remove Progress Bar
pb.setVisibility(ProgressBar.GONE);
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (FacebookError e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
});
}
随意在您自己的项目中使用任何此类代码,或者询问有关它的任何问题。

你可以private static final String[] PERMISSIONS = new String[] {"publish_stream","status_update",xxxx};
