scala - Liftweb return response from scalaz -

-

I have a next code, which is refunded: 

  import com.twitter Util {Future, nonfatal} import net.liftweb.http {LiftResponse, OkResponse} def service. (Str: Strign) :. Future [ValidationNel [String, LiftResponse]] = {if str == "Ok" future (OkResponse () successNel [string]) and Future.value ("Invalid string" .fileerNL [LiftSpons]) // and for this Roots {case "user" :: str :: _ get _ = & gt; Service (STR)}   
 But when I got to run, got  no built-in com.twitter.util.future [scalaz.ValidationNel [string, net.liftweb.http Available views. Lift response]] = & gt; Net.liftweb.http.LiftResponse.  How to change in ListResponse?   
  itemprop = "text"> 
 Well the error is basically saying that  
  com .twitter.util.Future [scalaz.ValidationNel [string, net.liftweb.http.liftResponse]]   can not be shown 
 (in time compilation.) To solve your problem You probably have to decompose your work.  
  scalaz.ValidationNel [string, net.liftweb.http.liftResponse]   
 If: First of all, lift out that "verification" thing can provide It can not be done to find out if you have to teach the elevator. You type sign sign  ValidationNel [***] = & gt; Should create an underlying (visible in the scope) with LiftResponse . You can probably convert it to a  box , which is the default way of providing error (empty box). Or you should write your custom code with "if" and 2 branches, one of which is  badresons  and the other is success.  
 Another task is to repeat the lift to present hot Twitter's  future  -s, you should make a simple data and try to render it . As  Future (Okaysons ()) . To teach elevator about twitter futures, you might type type sign  future [t] = & gt; LiftResponse . This would probably include a  restcontinance .

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...
