java - GlassFish session id when first time site is loading -

-

यहाँ समस्या है मुझे सत्र आईडी प्राप्त होती है: 

  request.getRequestedSessionId ();   
 हालांकि जब साइट पहली बार खुल रही है तो यह रिक्त है। केवल दूसरी विज़िट के साथ शुरू होने से यह सत्र आईडी लौटाता है लेकिन मुझे पहली बार पता होना चाहिए क्या मैं इसे प्राप्त कर सकता हूं?   
 
 
 यह शून्य है क्योंकि कोई सत्र नहीं है।  
 इसके बजाय:  
  request.getSession (true) .getId ()   
 जो एक सत्र बनाएगा यदि कोई मौजूद नहीं है, तो एक अद्वितीय सत्र पहचानकर्ता प्रदान करता है ।

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

c++ - Qt::make_shared for creating QSharedPtr as std::make_shared for creating std::shared_ptr -

-
As stated in the Barjini Stroustrup's "A Tour of C ++", and a known C ++ 14 practice As such, someone should avoid the naked code in the new and delete . Provides std :: make_shared and std :: make_unique to create smart pointers to store allocated items in the standard library. However, it is not possible to use these routines for non-standard smart pointers, such as QT's own memory management model (with parent), but also smart pointer class like Provides QSharedPointer and QPointer (although later it is not actually a brochure indicator). My question is: Is not it convenient to create Qt analog of std :: make_shared ? To like it, QSharedPtr : Namespace Qt {template & lt; Class T, squares ... Args & gt; QSharedPointer & LT; T & gt; Make_shared (erg & amp; ... args) {return QSharedPointer & lt; T & gt; (New t (std :: forward & lt; ergos & gt; (args) ...)); }} or to create this, QPointer : named place ...
