问题描述

SDK版本为v1.61.1127，示例代码为官方sdk demo代码，运行到response, err := client.DescribeSiteMonitorData(request)这行代码报错，err 总是不等于 nil，无法正常解析接口数据。

示例代码

package main

import (
        "fmt"
        "os"
        cms "github.com/aliyun/alibaba-cloud-sdk-go/services/cms"
        "github.com/aliyun/alibaba-cloud-sdk-go/sdk/requests"
)

func main() {
        client, err := cms.NewClientWithAccessKey("cn-hangzhou", os.Getenv("ACCESS_KEY_ID"), os.Getenv("ACCESS_KEY_SECRET"))

        request := cms.CreateDescribeSiteMonitorDataRequest()
        request.Scheme = "https"

        request.TaskId = "df358848-e202-41be-a446-xxxxxxxxxxxx"
        request.MetricName = "Availability"

        response, err := client.DescribeSiteMonitorData(request)
        if err != nil {
                fmt.Print(err.Error())
        }
        fmt.Printf("response is %#v\n", response)
}

运行结果

更新的 SDK 的版本看看是否解决该问题。

该问题的背后原因是 API 声明的类型与实际返回的类型不一致导致的。

@JacksonTian 试了最新版本的SDK，报错和上面相同。

go.mod

module main.go
go 1.16
require github.com/aliyun/alibaba-cloud-sdk-go v1.61.1184

go.sum

@JacksonTian 我尝试修改SDK中Data的数据结构，将Data改为数组类型，运行不再报错了。希望SDK可以及时更新，谢谢。

// DescribeSiteMonitorDataResponse is the response struct for api DescribeSiteMonitorData
type DescribeSiteMonitorDataResponse struct {
    *responses.BaseResponse
    Code      string `json:"Code" xml:"Code"`
    Message   string `json:"Message" xml:"Message"`
    Success   string `json:"Success" xml:"Success"`
    RequestId string `json:"RequestId" xml:"RequestId"`
    NextToken string `json:"NextToken" xml:"NextToken"`
    Data      []metricData
}

type metricData struct {
    Availability float32 `json:"Availability"`
    AvailableNumber  int `json:"AvailableNumber"`
    UnavailableNumber int `json:"UnavailableNumber"`
}

请注意： Success字段返回值为bool类型 AvailableNumber等字段返回值为float类型

type DescribeSiteMonitorDataResponse struct {
    *responses.BaseResponse
    Code      string `json:"Code" xml:"Code"`
    Message   string `json:"Message" xml:"Message"`
    Success   bool   `json:"Success" xml:"Success"`
    RequestId string `json:"RequestId" xml:"RequestId"`
    NextToken string `json:"NextToken" xml:"NextToken"`
    Data      []metricData  `json:"Data" xml:"Data"`
}
type metricData struct {
    Availability float32 `json:"Availability" xml:"Availability"`
    AvailableNumber  float32 `json:"AvailableNumber" xml:"AvailableNumber"`
    UnavailableNumber float32 `json:"UnavailableNumber" xml:"UnavailableNumber"`
}

问题得到临时解决，故关闭问题。如需继续讨论请在后面回复。谢谢。
