ios - Swift. Mapping from JSON to object model. Array of Array -

-

There is a model in JSON format 

  {"offline": incorrect, "data": {"Path": [[{"Latitude": 56.789351316653, "Longitude": 60.6053340947616}, {"Latitude": 56.78674, "Longitude": 60.60613}], [{"Latitude": 56.79071, "Longitude": 60.60492} , And the object model at the speed  
  
 Issue: {"latitude": 56.79129, "longitude": 60.60493}]]}}   
 Json's path field can not be parsed, because there is an array of arrays that works well in all cases of arrays with a single dimension.   
 
 
 I had to do something like that. I considered the implementation of mtl_JSONArrayTransformerWithModelClass which changes an array of MTLModels and their structures. So I have created a similar transformer, which expects the array of dictionaries / MTLModels. . I change each array to iterate and dictionaries on the external array with  
  + (NSValueTransformer *) JSONArrayOfArraysTransformerWithModelClass: (Class) modelClass NSValueTransformer * arrayTransformer = [NSValueTransformer mtl_JSONArrayTransformerWithModelClass: modelClass]; Return [MTLValueTransformer reversibleTransformerWithForwardBlock: ^ ID (NSArray * arrays) {if (arrays == zero) return zero; NSAssert ([arrays isKindOfClass: NSArray.class], @ "An array is estimated, found:% @", Erase); NSMutableArray * modelArrays = [ability with NSMutableArray array: [arrays count]]; (For Jason Array at ARA) {if (Jasonrey == NSNLL.Annal) {[Model Aid Object: JasonArere]; to continue; } NSAssert ([JSONArray isKindOfClass: NSArray.class], @ "An array of arrays of dictionaries is expected; array of:% @", JSONArray); NSArray * modelArray = [Array transformer has been changed: JSONArray]; If (model array == zero) will continue; [ModelAddOct: ModelArere]; } Return Model Array; } ReverseBlock: ^ id (NSArray * arrays) {if (arrays == zero) return zero; NSAssert ([arrays isKindOfClass: NSArray.class], @ "Expected an array of arrays of MTLModels, found:% @", arrays); NSMutableArray * modelArrays = [Capacity with NSMutableArray array: ModelArerez coat]; (ID ModelArray in ARD) {if (modelArray == NSNull.null) {[modelArrays addObject: NSNull.null]; to continue; } NSASARArt ([ModelArrayHindindOfClass: NSARRA.clus], @ "An array of arrays was estimated, array of:% @", modelArere); NSArray * array = [arrayTransformer reverse transcript value: modelArere]; If (array == zero) will continue; [Model addObject: array]; } Return Model Array; }];   
}

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...
