I am trying to do this data conversion but I am stuck. I have this json request body:
{
"city": "XYZ",
"vouchers" :[
{
"voucherCode": "VOUCHERA",
"amount": 1000
},
{
"voucherCode": "VOUCHERB",
"amount":23
}
]
}
I want to get the vouchers
json array and pass it as a request payload to another API. Currently I am doing this to get the vouchers
array:
type vouchers struct {
Vouchers []interface{} `json:"vouchers" form:"vouchers"`
}
vouchers := vouchers{}
json.Unmarshal(reqBody, &vouchers)
This gives me the vouchers
object but how do I convert this to an io.Reader
object and send it as a payload to another API?
CodePudding user response:
Figured out one way to solve it, thanks to some help on the Discord Gophers channel. vouchers
json object can be unmarshalled into a field of type json.RawMessage
, which then can be passed in bytes.NewReader
.
type vouchers struct {
Vouchers json.RawMessage `json:"vouchers" form:"vouchers"`
}
vouchers := vouchers{}
json.Unmarshal(reqBody, &vouchers)
This can be later passed as a payload to another API using bytes.NewReader(vouchers.Vouchers)
.
