我是第一次涉足GO，我用來取得股票價格的API 接受多個股票代號（想想股票ID； NVDA => Nvidia），以減少我有限的API 呼叫。 然而，當嘗試獲取多個程式碼時，正文似乎被切斷：
{
"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 ": ""
在郵差直接對 Stock API 進行精確呼叫會回傳：
{
"meta": {
"requested": 2,
"returned": 2
},
"data": [
{
"ticker": "MSFT",
"name": "Microsoft Corporation",
"exchange_short": null,

"mic_code": "IEXG",
"currency": "USD",

"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,

},

"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"
}
]
}
我認為我做錯了什麼（昨天之前我從未接觸過 GO） 相關程式碼如下：
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
}
上下文結構：
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"`
}
在查看了幾個線程後，我嘗試使用 json.Unmarshal 和 json.NewDecoder().Decode() 但仍然沒有運氣。上面的截止字串來自正文，當使用 Decode 或 Unmarshal 時，它成功地將單一完整物件新增至 apiResponseData 中。我可以理解這是否是一個巨大的回應，但這看起來很簡單，所以我不得不假設我犯了一個非常明顯的菜鳥錯誤。
任何幫助將不勝感激。
您正在嘗試使用包含時區偏移量（“Z07:00”）的格式來解析時間字串。
您需要將時間佈局調整為以下。
layout := "2006-01-02T15:04:05.000000"
您的錯誤處理不正確，這就是為什麼您也能夠以錯誤的回應退出。
以上是我的 API 回應正文似乎被截斷了？的詳細內容。更多資訊請關注PHP中文網其他相關文章！
