Could you help me to understand why I'm always getting the error unexpected
end of JSON input while trying to unmarshal the following json to the
LimitOrder struct? It works if I use golang playground
https://play.golang.org/p/udPQ_TayXG but not locally running tests.
P.S.: if I use map[string]json.RawMessage instead of LimitOrder struct I'm
able to execute the unmarshal.
{
"response_data": {
"order": {
"order_id": 3,
"coin_pair": "BRLBTC",
"order_type": 1,
"status": 4,
"has_fills": true,
"quantity": "1.00000000",
"limit_price": "900.00000",
"executed_quantity": "1.00000000",
"executed_price_avg": "900.00000",
"fee": "0.00300000",
"created_timestamp": "1453835329",
"updated_timestamp": "1453835329",
"operations": [
{
"operation_id": 1,
"quantity": "1.00000000",
"price": "900.00000",
"fee_rate": "0.30",
"executed_timestamp": "1453835329"
}
]
}
},

"server_unix_timestamp": "1453835329"}
*LimitOrder struct*
type LimitOrder struct {
OrderId int `json:"order_id"`
CoinPair string `json:"coin_pair"`
OrderType int `json:"order_type"`
Status int `json:"status"`
HasFills bool `json:"has_fills"`
Quantity float64 `json:"quantity,string"`
LimitPrice float64 `json:"limit_price,string"`
ExecutedQuantity float64 `json:"executed_quantity,string"`
ExecutedPriceAvg float64 `json:"executed_price_avg,string"`
Fee float64 `json:"fee,string"`
Operations []*Operation `json:"operations"`
CreatedTimestamp string `json:"created_timestamp"`
UpdatedTimestamp string `json:"updated_timestamp"`}
and this is how I'm trying to unmarshal it
func (limitOrder *LimitOrder) UnmarshalJSON(buf []byte) error {
tmp := make(map[string]json.RawMessage)
if err := json.Unmarshal(buf, &tmp); err != nil {
return err
}
tmp2 := make(map[string]json.RawMessage)
if err := json.Unmarshal(tmp["response_data"], &tmp2); err != nil {
return err
}
if err := json.Unmarshal(tmp2["order"], limitOrder); err != nil {
return err
}
return nil}
