如何在 Groovy 中创建动态长度的 Json 数组

Question

I am using Groovy in Soap UI. I have requirement to create dynamic JSON array. Let's say I am getting an count as 12, then I need to create a JSON Array as {["ID": 1234,"Desc":"Apple"]} and I have to repeat ID and Desc with different values to create 12 array object in single JSON.

def IDValue = ... // One Array where all IDs are stored
def Description = ... // Second Array where all desc are stored
JsonBuilder builder = new JsonBuilder()
for(int i=0; i<Array.length; i++) {
    def currIDValue = IDValue[i] 
    def currDescription =Description[i]
    builder{Details([i].collect{[id : currIDValue,"Desc": currDescription]})}
}

Log.info builder.toPrettyString()

While print only last value is coming of both the array in JSON I have wanted all the values should come in JSON as JSON objects in Detail array

​Does this helps you :

import groovy.json.*
def IDValue = [1,2,3,4]
def Description = ["decs1","decs2","decs3","decs4"]
def array=[]

for(int i=0; i<3; i++) {
   array+=["Id": IDValue[i], "Desc":Description[i]]
}

JsonBuilder builder = new JsonBuilder(array)
println builder.toPrettyString()​

You can transpose the two arrays and then collect over the resulting pairs. Eg

def ids = [1,2,3,]
def descs = ["a", "b", "c",]

[ids, descs].transpose().collect{ id, desc -> [id: id, desc: desc] }
// → [[id:1, desc:a], [id:2, desc:b], [id:3, desc:c]]
