你可以帮我理解为什么我总是在尝试将以下json解组为unexpected end of JSON input
结构时遇到错误LimitOrder
吗?
P.S。:如果我使用map[string]json.RawMessage
而不是LimitOrder
结构,我可以执行解组。
{
"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"
}
]
}
},
"status_code": 100,
"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"`
}
这就是我试图解组它的方式
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
}

我在golang-nuts组找到了一些帮助。您可以在https://groups.google.com/forum/#!topic/golang-nuts/SZXBcXgUoo0查看答案。长话短说,问题在于我的结构,我只为整个json的一小部分构建了结构,所以我修复了整个json响应的构建结构。
