{
"result" : "success",
"students" : [
{ "name" : "John", "age" : 10 },
{ "name" : "Paul", "age" : 16 },
{ "name" : "George", "age" : 17 },
{ "name" : "Ringo", "age" : 18 }
]
}
You can iterate "students" node by the following condifuration:
root: $.students
schema:
- {name: name, type: string}
- {name: age, type: long}
If you want to handle more complicated json, you can specify jsonpath to also path in schema section like as follows:
{
"result" : "success",
"students" : [
{ "names" : ["John", "Lennon"], "age" : 10 },
{ "names" : ["Paul", "Maccartney"], "age" : 10 }
]
}
root: $.students
schema:
- {name: firstName, type: string, path: "names[0]"}
- {name: lastName, type: string, path: "names[1]"}
In this case, names[0] will be firstName of schema and names[1] will be lastName.
