我有以下控制器，它使用 Go 中內置的包裝器進行外部 API 調用。問題是，如果我在沒有 docker 的情況下運行我的服務器，端點將返回有效數據。但是，當我從 docker 中運行它時，我得到的錯誤是unexpected end of JSON input.回家去package controllersimport (  "fmt"  "encoding/json"  "net/http"  "time"  "strconv"  cmc "github.com/coincircle/go-coinmarketcap")type HomeController struct{}func NewHomeController() *HomeController {  return &HomeController{}}func (hc HomeController) IndexEndpoint(w http.ResponseWriter, r *http.Request) {  threeMonths := int64(60 * 60 * 24 * 90)  now := time.Now()  secs := now.Unix()  start := secs - threeMonths  end := secs  fmt.Println("Time is " + strconv.FormatInt(end, 10))  graph, _ := cmc.TickerGraph(&cmc.TickerGraphOptions{    Start: start,    End: end,    Symbol: "ETH",  })  fmt.Println(graph)  w.Header().Set("Access-Control-Allow-Origin", "*")  w.Header().Set("Content-Type", "application/json")  w.WriteHeader(http.StatusCreated)  json.NewEncoder(w).Encode(graph)}這是我的泊塢窗設置：文件FROM golang:latest AS builderCOPY . $GOPATH/src/github.com/gohuygo/cryptodemo-apiWORKDIR $GOPATH/src/github.com/gohuygo/cryptodemo-apiRUN go get ./RUN CGO_ENABLED=0 GOOS=linux go build -a -installsuffix nocgo -o /app .FROM scratchCOPY --from=builder /app ./ENTRYPOINT ["./app"]為什么在涉及 docker 時抱怨 json 錯誤（即如何解決這個問題）？謝謝
