直到昨天,我的应用程序才将提要故事发布到 Facebook 上。
现在它停止工作并在回调中发送此错误:
“com.facebook.FacebookException:无法构造请求正文”
这来自:
response.getError();
奇怪的是,来自 facebook 的示例应用程序停止工作,现在报告同样的错误,我很确定我没有更改任何内容。
这是示例应用程序功能:
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) {
FacebookRequestError error = response.getError();
if (error != null) {
Toast.makeText(getApplicationContext(),
error.getErrorMessage(),
Toast.LENGTH_SHORT).show();
return;
}
JSONObject graphResponse = response
.getGraphObject()
.getInnerJSONObject();
String postId = null;
try {
postId = graphResponse.getString("id");
} catch (JSONException e) {
Log.i("publishStory",
"JSON error "+ e.getMessage());
}
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();
}
}
任何人都可以帮忙吗!先感谢您。
