GetJSON

Convert JSON string to JSON data structure

Declaration

Source position: fpjson.pp line 617

function GetJSON(

  const JSON: TJSONStringType;

  const UseUTF8: Boolean = True

):TJSONData;

function GetJSON(

  const JSON: TStream;

  const UseUTF8: Boolean = True

):TJSONData;

Arguments

JSON

  

The JSON to parse.

UseUTF8

  

Convert unicode characters to UTF-8

Function result

The TJSONData data (tree) represented by JSON

Arguments

JSON

  

The JSON to parse.

UseUTF8

  

Convert unicode characters to UTF-8

Description

GetJSON will read the JSON argument (a string or stream that contains a valid JSON data representation) and converts it to native JSON objects. The stream must be positioned on the start of the JSON.

The fpJSON unit does not contain a JSON parser. The jsonparser unit does contain a JSON parser, and must be included once in the project to be able to parse JSON. The jsonparser unit uses the SetJSONParserHandler call to set a callback that is used by GetJSON to parse the data.

If UseUTF8 is set to true, then unicode characters will be encoded as UTF-8. Otherwise, they are converted to the nearest matching ansi character.

Errors

An exception will be raised if the JSON data stream does not contain valid JSON data.
