我在facebook开发者网站创建了一个应用程序并在我的应用程序中使用appId并尝试在Facebook上发布，当我在我的应用程序中使用相同的fb帐户登录并使用我的Facebook发布时，它发布成功，但是当我尝试使用其他帐户登录但不发布...可以任何身体帮助......

如果您想将某些内容发布到用户的墙上，则应根据https://developers.facebook.com/docs/graph-api/reference/v2.0/user/feed/#publish申请publish_actions权限。
如果您使用不同的帐户，是否看到权限对话框？我怀疑你尝试使用它的第一个用户是你应用的管理员，而第二个用户不是。这就是为什么它适用于第一个。

感谢Tobi的回复..我找到了另一个在facebook上分享数据的解决方案，使用Facebook团队现在推荐的提要对话框，如果你对Facebook上发布的内容有额外的对话，我们可以使用这个方法。但是请确保我们已经像Tobi所说的那样获得了所有许可。
private void publishFeedDialog() {
Bundle params = new Bundle();
params.putString("name", "Product shared from Bee2buy");
params.putString("caption",
appPref.getData("share_title"));
params.putString("link", "http://www.saznaitsols.com/site_uploads/product/"
+ appPref.getData("share_img"));
params.putString("picture",
"http://www.saznaitsols.com/site_uploads/product/"
+ appPref.getData("share_img"));
WebDialog feedDialog = (new WebDialog.FeedDialogBuilder(
ShareData.this, currentSession, params))
.setOnCompleteListener(new OnCompleteListener() {
@Override
public void onComplete(Bundle values,
FacebookException error) {
if (error == null) {
// When the story is posted, echo the success
// and the post Id.
final String postId = values.getString("post_id");
if (postId != null) {
Toast.makeText(ShareData.this,
"Posted story, id: " + postId,
Toast.LENGTH_SHORT).show();
} else {
// User clicked the Cancel button
Toast.makeText(
ShareData.this
.getApplicationContext(),
"Publish cancelled", Toast.LENGTH_SHORT)
.show();
}
} else if (error instanceof FacebookOperationCanceledException) {
// User clicked the "x" button
Toast.makeText(
ShareData.this.getApplicationContext(),
"Publish cancelled", Toast.LENGTH_SHORT)
.show();
} else {
// Generic, ex: network error
Toast.makeText(
ShareData.this.getApplicationContext(),
"Error posting story", Toast.LENGTH_SHORT)
.show();
}
}
}).build();
feedDialog.show();
}
