Saya memasuki GO buat kali pertama dan API yang saya gunakan untuk mendapatkan harga saham menerima berbilang tanda (fikirkan ID saham; NVDA => Nvidia) untuk mengurangkan panggilan API terhad saya. Walau bagaimanapun, apabila cuba mendapatkan berbilang kod, teks kandungan nampaknya terputus:
{ "meta ": { "requested ": 2, "returned ": 2 }, "data ": [ { "ticker ": "MSFT ", "name ": "Microsoft Corporation ", "exchange_short ": null, "exchange_long ": null, "mic_code ": "IEXG ", "currency ": "USD ", "price ": 374.72, "day_high ": 376.92, "day_low ": 373.54, "day_open ": 374.94, "52_week_high ": 349.84, "52_week_low ": 213.43, "market_cap ": null, "previous_close_price ": 374.58, "previous_close_price_time ": "2023-12-22T15:59:56.000000 ", "day_change ": 0.04, "volume ": 165558, "is_extended_hours_price ": false, "last_trade_time ": "2023-12-26T16:00:00.000000 " }, { "ticker ": ""
Memanggil API Saham secara langsung dalam Posmen mengembalikan:
{ "meta": { "requested": 2, "returned": 2 }, "data": [ { "ticker": "MSFT", "name": "Microsoft Corporation", "exchange_short": null, "exchange_long": null, "mic_code": "IEXG", "currency": "USD", "price": 374.72, "day_high": 376.92, "day_low": 373.54, "day_open": 374.94, "52_week_high": 349.84, "52_week_low": 213.43, "market_cap": null, "previous_close_price": 374.58, "previous_close_price_time": "2023-12-22T15:59:56.000000", "day_change": 0.04, "volume": 165558, "is_extended_hours_price": false, "last_trade_time": "2023-12-26T16:00:00.000000" }, { "ticker": "PLTR", "name": "Palantir Technologies Inc", "exchange_short": null, "exchange_long": null, "mic_code": "IEXG", "currency": "USD", "price": 17.68, "day_high": 17.75, "day_low": 17.34, "day_open": 17.45, "52_week_high": 17.16, "52_week_low": 5.92, "market_cap": null, "previous_close_price": 17.42, "previous_close_price_time": "2023-12-22T15:59:56.000000", "day_change": 1.47, "volume": 236201, "is_extended_hours_price": false, "last_trade_time": "2023-12-26T15:59:58.000000" } ] }
Saya rasa saya melakukan sesuatu yang salah (saya tidak pernah menyentuh GO sebelum semalam) Kod yang berkaitan adalah seperti berikut:
func getStockPriceData(ticker string) []Stock { baseURL, _ := url.Parse("https://api.stockdata.org") baseURL.Path += "v1/data/quote" params := url.Values{} params.Add("symbols", ticker) params.Add("api_token", apiToken.ApiToken) baseURL.RawQuery = params.Encode() req, _ := http.NewRequest("GET", baseURL.String(), nil) res, _ := http.DefaultClient.Do(req) defer res.Body.Close() body, err := io.ReadAll(res.Body) if err != nil { panic(err.Error()) } apiResponseData := ApiResponseStockData{} //json.NewDecoder(res.Body).Decode(&apiResponseData) err2 := json.Unmarshal(body, &apiResponseData) if err2 != nil { fmt.Println("whoops:", err2) } stocks := []Stock{} for _, data := range apiResponseData.ResponseStockData { stock := Stock{} stock.Name = data.Name stock.Ticker = data.Ticker stock.Price = data.Price stock.DayHigh = data.DayHigh stock.DayLow = data.DayLow stock.DayOpen = data.DayOpen stock.PreviousClosePrice = data.PreviousClosePrice stock.DayChange = data.DayChange stocks = append(stocks, stock) } return stocks }
Struktur konteks:
type Stock struct { Name string `json:"name"` Ticker string `json:"ticker"` Price float64 `json:"price"` DayHigh float64 `json:"day_high"` DayLow float64 `json:"day_low"` DayOpen float64 `json:"day_open"` DayChange float64 `json:"day_change"` PreviousClosePrice float64 `json:"previous_close_price"` } type ApiResponseStockData struct { ResponseStockData []ResponseData `json:"data"` } type ResponseData struct { Name string `json:"name"` Ticker string `json:"ticker"` ExchangeShort bool `json:"exchange_short"` ExchangeLong bool `json:"exchange_long"` MicCode string `json:"mic_code"` Currency string `json:"currency"` Price float64 `json:"price"` DayHigh float64 `json:"day_high"` DayLow float64 `json:"day_low"` DayOpen float64 `json:"day_open"` DayChange float64 `json:"day_change"` YearHigh float64 `json:"52_week_high"` YearLow float64 `json:"52_week_low"` MarketCap float64 `json:"market_cap"` PreviousClosePrice float64 `json:"previous_close_price"` PreviousCloseTime time.Time `json:"previous_close_time"` Volume float64 `json:"volume"` IsExtendedHoursPrice bool `json:"is_extended_hours_price"` LastTradeTime time.Time `json:"last_trade_time"` }
Selepas melihat beberapa benang, saya cuba menggunakan json.Unmarshal
和 json.NewDecoder().Decode()
但仍然没有运气。上面的截止字符串来自正文,当使用 Decode
或 Unmarshal
时,它成功地将单个完整对象添加到 apiResponseData
Medium. Saya boleh faham jika ini adalah respons yang besar, tetapi ini nampaknya sangat mudah sehingga saya perlu menganggap saya membuat kesilapan rookie yang sangat jelas.
Sebarang bantuan amat kami hargai.
Anda cuba menghuraikan rentetan masa menggunakan format yang mengandungi offset zon waktu ("Z07:00").
Anda perlu melaraskan susun atur masa kepada yang berikut.
layout := "2006-01-02T15:04:05.000000"
Pengendalian ralat anda tidak betul, itulah sebabnya anda juga boleh keluar dengan respons yang salah.
Atas ialah kandungan terperinci Badan tindak balas API saya nampaknya dipotong?. Untuk maklumat lanjut, sila ikut artikel berkaitan lain di laman web China PHP!
