【问题描述】:
我在 Facebook 墙上发帖时遇到了一个问题。我使用 facebook SDK,我的代码如下。
下面的代码询问:myApp 你想代表你发布。但是我的 fb 墙上没有发布任何内容。请给我建议,我如何在 Facebook 墙上发帖。我想从我的应用程序中发布静态文本。例如 String message = "Hello all";将通过我的应用发布在我的墙上。
private void publishStory() {
Session session = Session.getActiveSession();
if (session != null){
// Check for publish permissions
List<String> permissions = session.getPermissions();
if (!isSubsetOf(PERMISSIONS, permissions)) {
pendingPublishReauthorization = true;
Session.NewPermissionsRequest newPermissionsRequest = new Session
.NewPermissionsRequest(this, PERMISSIONS);
session.requestNewPublishPermissions(newPermissionsRequest);
return;
}
Bundle postParams = new Bundle();
postParams.putString("name", "Facebook SDK for Android");
postParams.putString("caption", "Build great social apps and get more installs.");
postParams.putString("description", "The Facebook SDK for Android makes it easier and faster to develop Facebook integrated Android apps.");
postParams.putString("link", "https://developers.facebook.com/android");
postParams.putString("picture", "https://raw.github.com/fbsamples/ios-3.x-howtos/master/Images/iossdk_logo.png");
Request.Callback callback= new Request.Callback() {
public void onCompleted(Response response) {
JSONObject graphResponse = response
.getGraphObject()
.getInnerJSONObject();
String postId = null;
try {
postId = graphResponse.getString("id");
} catch (JSONException e) {
Log.i("HERE",
"JSON error "+ e.getMessage());
}
FacebookRequestError error = response.getError();
if (error != null) {
Toast.makeText(getApplicationContext(),
error.getErrorMessage(),
Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(getApplicationContext(),
postId,
Toast.LENGTH_LONG).show();
}
}
};
Request request = new Request(session, "me/feed", postParams,
HttpMethod.POST, callback);
RequestAsyncTask task = new RequestAsyncTask(request);
task.execute();
}
}
private boolean isSubsetOf(Collection<String> subset, Collection<String> superset) {
for (String string : subset) {
if (!superset.contains(string)) {
return false;
}
}
return true;
}
