ios - how to pass jsonData to other ViewController in Swift? -

-

I am trying to log the user's json data as soon as the next view controller and some details. But I am unable to pass that JSData. If I declare a global variable in the first ViewController, then I can pass it in another viewer. But I am declaring JSDTDa to go inside a condition and I am unable to send it. I tried to retrieve all the details of Jasonson at the global level and shared it in another viewer. But I can not because it can only be achieved within the situation.

Any help is appreciated 

  jsonData: NSDictionary = NSJSONSerialization.JSONObjectWithData (urlData !, Option: NSJSONReadingOptions.MutableContainers, Error: and Error) Come on NSDictionary jsonArray: AnyObject! = JsonData.valueForKey ("user") NSLog ("jsonddata = \ (jsonArray)") if (segue.identifier == "login_success") {var svc = segue.destinationViewController welcome view controller; Svc.userNameText = userNameText.text svc.jsonArray = jsonArray    
 
 
 Try this way  
  override func readyForSegue (segue: UIStoryboardSegue !, sender: AnyObject!) {If (segue.identifier == "login_success") {var svc = segue! SecondViewController as .destinationViewController; Svc.toPass = textField.text}}

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...

.net - Creating a new Queue Manager and Queue in Websphere MQ (using C#) -

-
"itemprop =" text "> I am writing applications that use WebSphere MQ to send messages. My unittests (for flow), I want to verify that I have put the correct message on the response queue. I am trying to figure out how to do this. My main obstacle is that I think it might be scary to clear the queue before running in my queue because the same queue can be used by other applications, I thought a decent solution would be a new line The manager will remove the queue for my solidarity and after using it. So my question is: Is it possible to use C # by using queue manager and queue? After the For future reference and future people, who want to make queues. I thought how to make and remove IBM MQ QE (not quenhers) with PCM messaging. It is not very simple, but it can be done. We have implemented it in a library and it is being used to create and delete commands before and after integration tests. The most important part of the code in this library is shown in the...
