I tried a few options but with no results. If anyone knows some kind of solution it would be nice. I was trying with buger/jsonparser because of the parsing speed. Lets say i want to exclude object3 and assign it to MYVARIABLE
for exaple :
data:=[{object1}, {object2}, {object3}]
//this function iterates through the array
jsonparser.ArrayEach(data, func(key []byte, dataType jsonparser.ValueType, offset int, err error) {
MYVARIABLE:=key
return
})
Let's say that you have successfully parsed your data to struct.
And you would have an array of yourStruct []yourStruct, and assign the third element with empty struct like this :
yourStruct[2] = YourStruct{}
the third element is still there with empty value. And unfortunately in go you can't assign struct with nil value.
or you can convert the []byte of your data that has your json to string and iterate it over to the their element and remove it with empty char, but this would be an expensive approach.
As Kaedys said you can remove your array struct using slice like this :
yourStruct = yourStruct[:2]
fmt.Printf("resutl struct = %+v\n", yourStruct)
yourStruct = append(yourStruct[:2], yourStruct[3:]...). As long as the slice has a length of 3 or more, that won't panic (even though index 3 in a slice of length 3 is an invalid index, the runtime is coded to handle it properly).
