• Does everything with JSON of QML

  Hello

  Just trying to decide what type of template to use for the list, I wanted to do.

  It's true that I can't fully implement JSON in its entirety in QML? that is sort of the key (and everything else 100%) in QML, no C++ at all. (I have a JSON file I created)

  In the examples I see, to do a minimum implementation in C++ and more QML.

  Otherwise, I can use XML purely in QML but will not get the features of sort etc..

  Is everything is OK?

  I just noticed tonight that the 'global' Javascript object, in the environment of waterfalls QML, has a JSON object in it.

  This seems to be the JSON object standard ECMAscript 5 which is documented here: https://developer.mozilla.org/en-US/docs/Using_native_JSON

  By using it, you could make JSON.parse (somestring) and retrieve the result of the analysis of the JSON.  Similar to eval(), but probably better...

  Also a JSON.stringify () has to go the other way.

  These things were probably obvious to many who read this... was good news for me.

• Special characters in JSon of Webservice

  My application from a json object a webservice. After the analysis of the json object I find characters of strings you have coded something because, rather than get the string what frio! Aguero, paraguas, nunez y Belén. I get the Quebec is Warf chain! AGA¼ERO, Paraga¼as, Nua±ez y Bela © n.

  How can I solve this problem? How can I get the correct characters in the string?

  Replace this:

  if(ResponseCode == HttpConnection.HTTP_OK) {}
  InputStream in = connection.openInputStream ();
  StringBuffer buf = new StringBuffer();
  int read = - 1;
  While ((read = in.read ())! = - 1).
  buf. Append ((Char) Read);
                  
  response = buf.toString ();
  response = new String (read, "UTF - 8");
  }

  with the following (this is from memory, so probably has a syntax error - but you get the idea):

  if(ResponseCode == HttpConnection.HTTP_OK) {}
  InputStream in = connection.openInputStream ();
  Byte [] read is (in) IOUtilities.streamToBytes;.
  response = new String (read, "UTF - 8");
  }

• Qbytearray json analytical problems

  help the analysis of this json:

  {"coord":{"lon":-97.87,"lat":22.26},"sys":{"country":"MX","sunrise":1383827966,"sunset":1383868260},"weather":[{"id":800,"main":"Clear","description":"Sky is Clear","icon":"01n"}],"base":"cmc stations","main":{"temp":26.928,"temp_min":26.928,"temp_max":26.928,"pressure":1026.4,"sea_level":1027.46,"grnd_level":1026.4,"humidity":85},"wind":{"speed":4.46,"deg":77.0002},"clouds":{"all":0},"dt":1383786373,"id":3530594,"name":"Ciudad Madero","cod":200}
  

  I got it in a QByteArray as a buffer but I do not know how to mapping to take every part of it and use it on my labels later, I got this far and got some of them, but just a label

  const QByteArray buffer (response-> readAll());
  bool ok;

  BB::data :: JsonDataAccess ja;
  const QVariant jsonva = ja.loadFromBuffer (buffer);
  const QMap externalip = jsonva.toMap ();

  foreach (const QVariant & value, externalip) {}
  response += Celsius.ToString;
  }

  Consider the country...

  In the header, you would have a property:

  public:
  Q_PROPERTY (QString country READ country WRITE setCountry NOTIFY countryChanged);
  Q_INVOKABLE QString country() {
  return _country;
  }
  Q_SLOT void setCountry(QString c) {
    if (c!=_country) {
      _country = c;
      emity countryChanged(c);
    }
  }
  
  signals:
    void countryChanged(QString);
  
  private:  QString _country
  

  TheBody - that you had received new JSON

      JsonDataAccess jad;
      QVariantMap map(jad.loadFromBuffer(fred).toMap());
      QVariantMap sys(map["sys"].toMap());
      setCountry(sys["country"].toString());
  

  The QML would need to be linked to the property in the countryside...

• The analysis of lists in PL/JSON

  I'm working on parsing a json string that is stored in a CLOB table in oracle 11g. This process belongs to a long analysis of routine which analyzes the data and stores the values in another table, and I just noticed that part of my data is not out. The json analysis and valid with JSONLint. So I simplified the analysis to try to find out where I'm wrong.

  So my json out of my table looks like this.

  {

  'JSON_data': {}

  "plant_id": "3006."

  "transmit_time": "2015-12-18 11:57:45."

  'messages': [{}

  'work_msg': {}

  "msg_time": "2015-06-23 04:54:17", ".

  "trigger_type':"interval. "

  'vert_correction': 358,3,

  'ch_latitude': 37.916302,

  'ch_longitude':-87.487365,

  'ch_heading': 212,3,.

  'ch_cable_port': 1029.79,

  'ch_cable_stbd': 348.63,.

  'ch_depth':-27.03,

  'slurry_velocity': 25.71,.

  'slurry_density': 1.02,.

  'ch_rpm': 205.49,.

  'ch_psi': 540.89.

  'prod_instantaneous': 0,

  'prod_cumulative': 1216.100000,

  'outfall_latitude': 37.915967,

  'outfall_longitude':-87.484369,

  'outfall_heading': 120,7,.

  "pump_entries": [{}

  'pump_name': 'main ',.

  'empty': 12.73.

  'outlet_psi': 22,88

  }],

  "spud_entries": [{}

  'position': 6

  }]

  },

  'pipe_length_event': {}

  "msg_time": "2015-06-23 04:54:17", ".

  "length_floating": 970

  }

  }]

  }

  }

  My analysis is properly find and do his thing with the data "work_msg". It's the data 'pipe_length_event' that I don't get to. Here is my pl/sql procedure.

  DECLARE

  vCONTENT CLOB.
  v_parent_json json;
  v_json_message_list json_list;
  v_json_message_list_value json_value;
  v_parent_json_value json_value;

  BEGIN

  SELECT CONTENT IN SJM_TEMP4 vCONTENT;

  v_parent_json: = json (vCONTENT);
  v_parent_json: = json (v_parent_json.get (1));

  v_json_message_list: = json_list (v_parent_json.get ('messages'));

  DBMS_OUTPUT. Put_line (v_json_message_list. (Count);

  for message_loop_counter in 1... loop v_json_message_list. Count
  v_parent_json_value: = json (v_json_message_list.get (message_loop_counter)) .get (1);

  If v_parent_json_value.mapname = "work_msg" then
  DBMS_OUTPUT. Put_line ('FOUND: work_msg');
  on the other
  DBMS_OUTPUT. Put_line (v_parent_json_value.mapname);
  end if;

  END LOOP;

  END;

  My dbms_output first gives me a sublist from 1 account. 2. not so my analysis does not yet recognize the 'pipe_length_event' as a sublist of "messages".

  How can I get data 'pipe_length_event' by using this procedure? I am almost sure that it worked in the past, so my first thought is that json is formatted differently. Is the json in the wrong format?

  Thanks in advance.

  They moved their forums to StackOverflow.  I had posted my question there before here.  In any case, I found my own answer.  JSON is not properly formatted.  The 'work_msg' was not closed correctly, and "pipe_length_event" has not been opened in a new list.  So once I had that all squared away he analysed very well.

  For reference, the correct formatting is below.

• Json array analysis of problem

  I tried to parse a json response after completing the examples and code examples on the forum but there is no direct example to analyze something like [{'uri":"file:///accounts/1000/shared/camera/IMG_00000012.jpg'}], and I can't understand it, how can I enter loop for and print each uri in the response?

  Thanks for any help.

  What I do to analyze the json is the following

  JsonDataAccess jda;
  
  QVariantList list = jda.load(reply).value();
  

  Then you have a QVariantList and you can iterate over it. Hope this was somewhat helpful.

  EDIT:

  I have to say that the response is a response to a networkrequest. You will need to find a way to parse a file with json to a QVariantList. I guess google is your best friend for this. "QString to QVariantList" or "json to QVariantList". Something like that.

• The JSON Foursquare data analysis

  Hello world

  I'm trying to parse a JSON data I got foursquare place search webservice.

  What I really need, is only the City and the country of the result value of the research of venues. I'm not trying to bind the data to a lisy

  Any thoughts? Thank you!!

  The code below does not work

  JsonDataAccess jda;
  QVariant jsonQVariant=jda.load(networkReply).value();
  QVariantList venueList = jsonQVariant.toMap()["venues"].toList();
  
  foreach (QVariant v, venueList)
  {
      QVariantMap venueMap = v.toMap();
      showToast(venueNameMap.value("city").toString());
  }
  

  Below is the result of Foursquare sample json I need to analyze.

  {"meta":{"code":200},
  "response":
  {"venues":
  [{"id":"4cd8a50c15d8b60c4e31230e",
    "name":"HSBC Bank",

  The brackets indicate a list. If you already have a list and new json may not work.

  listOfValues := json_list(VIN_JSON);

• Impossible to import the bookmarks file (file is JSON or HTML)

  Recently, I reformatted my laptop with a friend (works in), and from what I remember, he saved bookmarks via the function "import and backup / Backup".
  When I went to import back into Firefox, and I sailed to the location of the file, it was apparently not recognized because it does not appear in the folder, in that I know that it is. While in this process, I noticed also that Firefox is either looking for a JSON or HTML file. When I looked more closely the backup file, I noticed that it doesn't have a file extension. When I looked at the properties of the file, it simply says "file". I went online looking for an online tool to identify the file and found TrID (http://mark0.net/onlinetrid.aspx/). When I ran across this identification software all that I got was:

  "The file appears to be crude/ASCII text. TrID is best suited for analysing binary files! »

  As I don't see any option in Firefox to load this file type, I wondered what could have been hurt during the backup process.
  I was able to open the file in Excel (just a hunch because it "seemed" be a text file based on the identification of online files). The file opened, useless of course, but at least it seems that the file is not corrupted in any case.

  Please could someone help me with this? I have all my links job search in this backup, and it would be a ton of effort to recreate all this!

  My Info:
  Windows XP Home Edition, SP3
  Firefox 14.0.1

  Hi cor - el,.

  Thank you! That solved! I remember years ago with a similar situation, but not Firefox and I thought to try this thing... but I guess I'm getting old... Laughing out loud

  Once again, thanks a lot!

• Implement the json JWT with labview web token

  I need to implement of JWT authentication with labview, how can it be done?

  I'm not aware of an existing library of JWT for LabVIEW. You can see the site of JWT to the creation and analysis of JWT requires:

  JSON encoder / decoder
