Best practice parsing JSON?

[Grovkillen]

If I fetch a supposed JSON string the JSON parser will throw an error if it's not a correct JSON format.

Could it be possible to have an option to return a error string instead or should I do a JSON validation myself before throwing an JSON to the parser?

Use IGNOREERRORS and/or ONERROR and look at the LAST_ERROR variable to see what the error is, if any.

Thanks Marcus! Worked like a charm!

If someone else is wondering:

Code: Select all

Let>ONERROR=CHECK_ERROR

Let>TEST_URL=https://jsonplaceholder.typicode.com/users
HTTPRequest>TEST_URL,,GET,,TEST_JSON,,,,
JSONParse>TEST_JSON,$[*]['id'],TEST_ID
MDL>TEST_ID_1

Let>TEST_URL=error
HTTPRequest>TEST_URL,,GET,,TEST_JSON,,,,
JSONParse>TEST_JSON,$[*]['id'],TEST_ID
MDL>TEST_ID_1

SRT>CHECK_ERROR
  //MDL>LAST_ERROR
  Let>TEST_ID_1=LAST_ERROR
END>CHECK_ERROR
