尝试解码 json 的正文时出现错误 "data1.Body undefined (type []byte has no field or method Body)"

Question

所以我再次尝试获取此数据，但它返回了

的错误

data.Body undefined (type []byte has no field or method Body)

在此代码的第 16 行和第 23 行。所以当它解码 json 如果有人能帮助我，这是我的代码

func SkyblockActiveAuctions() (structs.SkyblockActiveAuctions, error) {
    var auctions structs.SkyblockActiveAuctions
    startTime := time.Now()
    statusCode, data, err := fasthttp.Get(nil, "https://api.hypixel.net/skyblock/auctions")
    if err != nil {
        return auctions, err
    }
    fmt.Println(statusCode)
    var totalPages = auctions.TotalAuctions
    for i := 0; i < totalPages; i++ {
        statusCode, data1, err := fasthttp.Get(nil, "https://api.hypixel.net/skyblock/auctions")
        if err != nil {
            return auctions, err
        }
        fmt.Println(statusCode)
        json.NewDecoder(data1.Body).Decode(&auctions)
        fmt.Println(auctions.LastUpdated)
    }
    endTime := time.Now()
    var timeTook = endTime.Sub(startTime).Milliseconds()
    fmt.Println(data)

    json.NewDecoder(data.Body).Decode(&auctions)

    fmt.Println(auctions.LastUpdated)
    fmt.Println(timeTook)

    return auctions, err
}

Answer 1

    json.NewDecoder(data.Body).Decode(&auctions)

data.Body undefined (type []byte has no field or method Body)

data is already the body of the response.

json.NewDecoder expects an io.Reader but since fasthttp has already read the data into []byte, it would be more appropriate to use json.Unmarshal:

    err := json.Unmarshal(data, &auctions)
    if err != nil {
         return nil, err
    }

不要忘记处理来自 json.Unmarshal 的错误（或者，来自 json.Decoder.Decode 的错误）。如果 Json 解析失败，acutions 将不会保留预期的数据，因此您应该处理这种可能性。
