I'm trying to parse this petition (https://www.binance.com/api/v1/depth?symbol=MDABTC&limit=500)
I was having tons of problems to create an struct for it, so I used an automated tool, this is what my struct looks like:
type orderBook struct {
Bids [][]interface{} `json:"Bids"`
Asks [][]interface{} `json:"Asks"`
}
I recover and parse the petition by doing:
url := "https://www.binance.com/api/v1/depth?symbol=MDABTC&limit=500"
resp, err := http.Get(url)
if err != nil {
panic(err)
}
defer resp.Body.Close()
body, err := ioutil.ReadAll(resp.Body)
if err != nil {
panic(err)
}else{
book := orderBook{}
if err := json.Unmarshal(body, &book); err != nil {
panic(err)
}
But whenever I try to make an operation with the struct, like:
v := book.Asks[i][0] * book.Asks[i][1]
I get an error:
invalid operation: book.Asks[i][0] * book.Asks[i][1] (operator * not defined on interface)
How do I define it? Do I need to create an struct for bids/asks
, if so, how would that look like?
Sorry if this seems basic, I just started learning go.
