TALEND: How to extract JSON response body from API into Table in Talend?-CodePudding

I create a job in Talend to extract data from an API to MySQL table. I used tRest as input(data pull), and tLogRow for now to view it in table form.

I lost it at mapping the json response into column for each of the field and value.

but the response was in one string line, when it's prettier formatted:

{
 "data":
       {
        "user":
               [
                {"id":8, "name":"Alex"},
                {"id":9, "name":"John"}
               ]
        },
       "http_code":200,
       "message":[]
}

how can I turn this response and map into table like below

id	name
8	Alex
9	John

Glad if you guys have the working example too. Or using different components might help?

Here's how to set up tExtractJSONFields:

Loop path query needs to be:

$.data.user[*]

And just use the attribute names as json query for for each column.
The output:

.-- ----.
|tLogRow_1|
|=- ---=|
|id|name|
|=- ---=|
|8 |Alex|
|9 |John|
'-- ----'
