  As you can see, this site did not like all the stuff that are highlighted in red

  https://jsonformatter.curiousconcept.com/

  Parsing JSON was not working in the analysis of these data, and of course this image did not show in my ScriptUI dialog box.

  Any suggestions on how to format it to conform to the JSON syntax, if possible?

  Thanks Micky, it seemed that avoidance by means you listed had somehow changed some real characters, so it does not end up practicing in real code. However, I also noticed that the site I listed myself was less than optimal for understanding my problem: I used instead (http://codebeautify.org/jsonvalidate), I would have quickly noticed the blackslashes issue because it uses better syntax highlighting!

  Now, I decided to use encodeURI() to transform this channel of image data in a valid JSON string. It seems to work when you turn such a string directly in a ScriptUI.newImage (), but now I have to find one couple of other things to make sure he got by JSON analysis inside my script, I'm working on that.

• Convert string (JSON string) JSON object?

  * EDIT *.

  I finally understand how to use #include instead of file.read (); This solves my immediate problem. However, I am always curious to know if it is possible to do what I request below, just in case there is a situation where for some reason any I can not just use #include. Thank you all. =)

  * EDIT *.

  * EDIT 2 *.

  Someone knows how to use #include for a file whose name is determined during execution of the script?

  For example... the orderNumber variable is generated by a window (lets say that the result is 1234567). the file I want to include will be called "1234567.js).

  What I want to do, it is something like:

  #include ' ~/Desktop/Info folder / "orderNumber + '.js '.

  (then I want to assign a variable the result somehow, since it is simply an anonymous object at this stage and I don't know how to access its content);

  * EDIT 2 *.

  Hey all. I have a (probably stupid) question about how to take a string that contains the JSON text and simply modify this type of 'chain' to 'object '... I'm wording probably this very badly.

  I get a file .js on my local network and by assigning a variable the result of file.read ();

  The content of the file is an anonymous object in JSON. However, when I use the file.read (); the object is placed in the string, like this:

  "{"Alignment": [{'name': 'Fink', 'number': '19', 'jerseySize': 'XL', 'quantity': '1',"topId": '78531'}, {thi s is the next player}, {it is the next player}]}"

  It's a massively simplified version of what I read actually, but you get the point. I want to put this object in the script that I'm running and create new objects based on the relevant information (in this case I need only the values for 'name', 'number' and 'jerseySize').

  So my question is this. How can I activate the above JSON string into:

  alignment of var =]

  {

  "name':"Fink. "

  «number»: "19.»

  {"jerseySize": "XL"},

  {

  next player

  },

  {

  next player

  }

  ]

  ???? A google search reveals the JSON.parse (text) method. But that is not supported in ESTK.

  for simple objects, as in the example, you could use eval() hurt, get rid of the 'alignment' first

  var str = "[{'name': 'Fink', 'number': '19', 'jerseySize': 'XL', 'quantity': '1',"topId": '78531'}, {'name': 'Fink', 'number': '19', 'jerseySize': 'XL', 'quantity': '1',"topId": '78531'}] '"

  alignment of var = eval (str);

  $.writeln(roster[0].number);

• Adding a JSON string to a RESTful outgoing call in OSB 11.1.1.6

  Inside of my stream of messages of the Service Proxy (OSB 11.1.1.6), I have generated a JSON string and stored in a variable named $jsonReq.
  
  In my action of routing, I point to a Business Service that the Service Type is 'Messaging Service' with both Types of request/response as "Text" messages
  
  What is the right way to attribute the $jsonReq content of the variable for the body of the outgoing request (I'm making a POST)?
  
  I tried a number of configurations, but not prevail (although I see the content JSON when I throw out in a Log action), such as:
  
  Insert
  Expression: $jsonReq
  Location: as the first child of the
  XPath:.
  In Variable: coming out
  
  
  Please notify.
  
  Thank you
  Michael

  Use replace. / * in the variable body with $jsonReq choose replace entire node.

• The small JSON string loading

  This is probably a stupid question, but I'll ask it anyway.

  I have a class of datamodel who comes into contact with a web service and then recovers the JSON data. There is one case where I don't want JSON service but only a code. This code, I want to load a single line of JSON data. How to declare the JSON data to a local string instead of demand response?

  QVariantList m_jsonData;

  m_jsonData = jda.loadFromBuffer (buffer);

  JSON data '[{\"type\":\"99\",\"datesort\":\"\'}]".

  Thank you. Has got a brain lock this morning.

  @Zmey,

  It is declared as

  QVariantList m_jsonData;

  I changed the code of

  m_jsonData = jda.loadFromBuffer (buffer) .toList ();

  and everything worked. Thanks for the help and for having me on my brain freeze.

• Array of bytes in JSON string is not a valid JSONObject.

  I get an array of bytes from a URL that I can view in Google Chrome as a valid JSON object.

  When I get the answer to IOUtilities.streamToBytes (), it returns in the following way:

  [16, 8, 1, 10, 2,... 1, 0, 0, 8, 0, 0, 120, 2, 0]
  

  How can I convert the byte array to a human readable string I can spend in the JSONObject constructor?

  I tried the following character encodings:

  • "ISO-8859-1".
  • 'UTF-8 '.
  • "UTF-16BE".
  • "US-ASCII".

  Hello

  First, check with your http connection that it returns the appropriate response.

             connection=(HttpConnection)Connector.open(url,Connector.READ);
              connection.setRequestMethod(HttpConnection.GET);
              if(connection.getResponseCode()==HttpConnection.HTTP_OK)
              {
                  inputstream=connection.openInputStream();
                  int ch;
                  buffer=new StringBuffer();

                  {
                      buffer.append((char)ch);
                  }
                  System.out.println(buffer.toString());
              }
  

  If so, you need to spend just that data in json for parsing.i

• How to extract string in JSON data where the value in a table

  Hello

  Structure of JSON string

  {'name': 'John', 'name': 'kumar', 'address': [{'Address1': 'value', 'place': 'value'}, {'address2': 'value', 'place': 'value'}]}

   

  
  How to extract the value of the address of the list.

  If you have control over the format of data, it is best to rename address1 and address2 to have the same name, for example "address". Then, it can be analyzed that way (I've also simplified other code a bit):

  JsonDataAccess jda;
  QVariant v = jda.loadFromBuffer(jsonString);
  QVariantMap m = v.toMap();
  QString name = m["name"].toString();
  QString surname = m["surname"].toString();
  QVariantList addresses = m["address"].toList();
  foreach (QVariant addr, addresses)
  {  QVariantMap addrMap = addr.toMap();
    QString addressValue = addrMap["address"].toString();
    QString place = addrMap["place"].toString();
  }

  Change your simpleSearchFinished as follows

  ....simpleSearchFinished()

      QNetworkReply *reply = qobject_cast(sender());
      if (!reply->error()){
          QByteArray response = reply->readAll();
          response.replace("\\", "");
          if (response.startsWith("\"")){
              response.remove(0, 1);
          }
          if (response.endsWith("\"")){
              response.remove(response.length()-1, 1);
          }
          emit simpleSearchDone(response);
      }else{
          const int httpCode = reply->attribute(QNetworkRequest::HttpStatusCodeAttribute).toInt();
          qDebug() << "ErrorCode" << httpCode << endl << \
                  "ErrorString" << reply->errorString();
          emit error(httpCode, reply->errorString());
      }
      reply->deleteLater();
      manager->deleteLater();
  }
  

  and QML

  function simpleSearch(response){
      indicator.stop()
      model.clear()
      var json = JSON.parse(response)
      if (json){ // is VALID/PARSED
          model.append(json.search_result)
      }
  }
  

  As I wrote, it is not a good workaround solution. The best is to send VALID JSON string directly from your server. But it works

  

• How to record a little complex data in json?

  Hi all

  I want to use json to store complex data a bit. I checked the sample application code. It's too simple.

  The data are as follows:

  {

  'day': 'ddd ',.

  'type': 'xxx ',.

  'name': "qqq"

  "amandine":]

  {'name': 'sss', 'set': 'ddd', 'time': 'ddd'},

  {'name': 'eee', 'set': 'fff', 'time': 'fff'},

  {'name': 'qqq', 'set': 'ggg', 'time': 'ggg'},

  {'name': 'aaa', 'set': 'vvv', 'time': 'vvv'},

  {'name': 'zzz', 'set': 'ccc', 'time': "ccc"}

  ]

  }

  I am confused with QVaraintMap, QVariantList and QVariant and don't know how to use them properly.

  PS: I'm new to json. I used to use MySQL in my work.

  Thank you.

  brad_qqq

  The simplest approach is the following:

  JSON object (something wrapped in {}) will be a QVariantMap

  List of JSON (something wrapped in []) will be a QVariantList

  Everything else (numbers, strings, boolean, etc.) will be a QVariant

  Everything will be a QVariant when initially mapped out, and you must check the types with canConvert (Type) and use the methods toXXXX, that all return values (http://qt-project.org/doc/qt-4.8/qvariant.html) to get the respective types and use the data.

  Thank you

  You can use the class JsonDataAccess, QVariantList, QVariantMap, QVariant access JSON file structure: https://developer.blackberry.com/native/documentation/cascades/device_platform/data_access/working_w...

  Once you set your JSON to QVariantList, there are a lot of discussions in this forum who have excellent explanations on how to access the child elements and properties.

  I did change the numerical value in the field. Does Notepad save not a 'real' UTF-8 file? Someone else had this problem? Which makes it pretty hard to let users to change if the software cannot read it.

  Notepad adds a BOM header said at the beginning of the text file. This indicates a conscious drive UTF UTF type so boutien multibyte UTF encodings (e.g. UTF-16, UTF-16BE, UTF-32). Unfortuntaly notebook is so 'smart' to do it seamlessly and without any notification.

  If you use Notepad ++, or any other smarter text editor, you can avoid this problem of having this BOM autmagically added to the file to save.

  Basically, UTF - 8, you get three codes hexadecimal 0xEF, 0xBB, 0xBF at the start of the file. You can read the file yourself and check these three characters in this order and remove them if they exiist, before passing the string to your string in JSON format Unflatten and everything should be good.

  See here for more details on the UTF BOM.

• JSON Parser file path not found

  So I have a JSON file from which I am trying to retrieve data, but I can't get the correct path of the file. I use Unflatten of JSON

  The JSON string looks like this:

  {"latitude":32.78,"longitude":-96.81,"timezone":"America/Chicago","offset":-5,"currently":{"time":1478744444, "summary":"Mostly cloudy"},"minutely":{},"hourly":{"summary":"Rain","icon":"rain","data":[{"time":1478744555,"summary":"Cloudy","temperature":60.55,"windSpeed":14.5}{"time":1478745555,"summary":"Mildly cloudy","temperature":60.00,"windSpeed":13.5}]},"daily":{},"flags":{}}
  

  There is much more in the actual string, but the important part is the hourly data, which are divided into 48 different pieces for 48 hours. I know I can get the 'time' and 'summary' part 'currently', but whenever I try to get something 'all hours' or ' schedule / data "I get this error:" LabVIEW: the path is not found in the JSON string. "

  I can get the info 'currently' like this: it is just to show that the path is very simple, just "currently / hour ' and it works.

  But trying to do the same thing does not work with the array of objects:

  I also tried to make the type and by default is the same as what is in the elements of the array 'features', but the error is still the same.

  So is it possible to separate each of the time slices in the 'data', or to extract what is in the block of 'time' and then use the function JSON Unflatten on it again?

  You must include the array index in your path. The hooks in the json data indicate a table, to do something like the following:

  

  For some reason, I'm getting a "LabVIEW: the JSON string is not valid." Error in JSON strings must be encoded in UTF - 8 and must conform to the JSON grammar. ", but that might just be because of her copy + paste of the JSON string.

  Oh... missing the comma between the elements of the array. Add a comma after the wind speed':14.5} at the end of the 6th line.

  In your second example, you should have the cluster in an array of clusters containing 3 digital items - while must have worked. It takes a little getting used to understand how to convert JSON structures clustered LV.
