go - 从 golang 调用时无法从调用 GetConfiguration 获取 itemCategory 信息

Question

API调用

GET https://api.softlayer.com/rest/v3/SoftLayer_Product_Package/257/getConfiguration?objectMask=mask[itemCategory]

返回一个对象，[]datatypes.Product_Package_Order_Configuration 其中填充了 ItemCategory。示例输出:

{
"id": 7167,
"isRequired": 0,
"itemCategoryId": 390,
"orderStepId": 1,
"packageId": 257,
"sort": 0,
"itemCategory": {
"categoryCode": "trusted_platform_module",
"id": 390,
"name": "Server Security",
"quantityLimit": 1,
"sortOrder": 0
}
},

当我在 go 中尝试相同的调用时，itemCategory 没有被填充，即使我在掩码中声明了它。请指教。

package main

import (
"fmt"
"github.com/softlayer/softlayer-go/services"
"github.com/softlayer/softlayer-go/session"
"encoding/json"
)

func main() {
    // SoftLayer API username and key
    username := "set-me"
    apikey   := "set-me"

    // Create a session
    sess := session.New(username, apikey)

    // Enable debug
    sess.Debug = true

    // Get SoftLayer_Account service
    service := services.GetProductPackageService(sess)

    // Object-Mask to get specific Vlan's information
    mask := "itemCategory"

    // Call to getNetworkVlans in order to retrieve vlans according to filter.
    result, err := service.Mask(mask).Id(257).GetConfiguration()
    if err != nil {
        fmt.Printf("\n Unable to retrieve config:\n - %s\n", err)
        return
    }

    // Following helps to print the result in json format.
    jsonFormat, jsonErr := json.MarshalIndent(result,"","     ")
    if jsonErr != nil {
        fmt.Println(jsonErr)
        return
    }
    fmt.Println(string(jsonFormat))
}

示例输出:

默认端点是 REST，但在您的环境中您使用的是 xmlrpc，这可能是由于存在 ~/.softlayer 文件，并且在该文件中它被配置为 XMLRPC enpoint。

有关更多信息，您可以查看以下文档: https://github.com/softlayer/softlayer-go

此问题发生在 XMLRPC enpoint 上，您可以在 go GitHub 中报告它。 https://github.com/softlayer/softlayer-go/issues/

在您的代码中尝试使用 REST 端点，就像这个例子:

endpoint := "https://api.softlayer.com/rest/v3"

// Create a session
sess := session.New(username, apikey, endpoint)
