Hello, I have a problem parsing a JSON string and I need help. The string I receive: '[{"device_id":"1","pgt_id":"2","usertag":"3","hgl":"4","ls":"5","rs":"6","erg":"7"}]' The struct I devined: TYPE strPGTdataSet: STRUCT device_id :JSONVAR; pgt_id :JSONVAR; usertag :JSONVAR; hgl :JSONVAR; ls :JSONVAR; rs :JSONVAR; erg :JSONVAR; END_STRUCT END_TYPE The FB I call: ParseJSON( Execute:=xParseJSON, JSONString:= ADR(hTTPClient_0.httpResult.sContent), JSONStringSize:= SIZEOF(hTTPClient_0.httpResult.sContent), JSONVars:= ADR(NewJSONObj), NumberOfVars:= SIZEOF(NewJSONObj) / SIZEOF(JSONVAR) ); The NewJSONObj always remains empty. I also tried to define the NewJSONObj as an array of struct like this: TYPE strPGToutputSet: STRUCT recordset :ARRAY [0..0] OF strPGTdataSet; END_STRUCT END_TYPE I don't know if you need more information to help. Also I'm new to CODESYS programming. Thank you!

Hi, I haven't had time to test it, but have you tried recordset :ARRAY [1..1] OF strPGTdataSet;

Hi, you should add (GPL_JSON.MAX_VALUE_SIZE) on this string. Because if bigger value sizes it runs into faulty parse. TYPE JSONNAMEVALUE : STRUCT Value: STRING(GPL_JSON.MAX_VALUE_SIZE); //value of the object at this level END_STRUCT END_TYPE Greetings

I'll see if I can find some time to test this out.

Hello Guys, I believe there's an issue with nested structs on all verions. For example: TYPE stDebugJson : STRUCT timestamp : JSONVAR; messageType : JSONVAR; //message : JSONVAR; //works fine with setting MaxLevel to 1 message : stDebugMessageDetails; // missing end bracket END_STRUCT END_TYPE stDebugMessageDetails is just another type: TYPE stDebugMessageDetails : STRUCT message : JSONVAR; END_STRUCT END_TYPE The output looks like: {"debugMessageJson":{"timestamp":"2020-03-06T23:27:22.966Z","messageType":"DEBUG","message":{"message":"test22"}}
