Question

func getPrivateVlan(env string) (string, error) {
// 1. Create a session
sess := session.New(user, pass)
// 2. Get a service
accountService := services.GetAccountService(sess)
// 3. Invoke a method:
vlans, err := accountService.GetNetworkVlans()
vlan := vlans[0]
log.Println(*vlan.Name)           //works
log.Println(*vlan.PrimaryRouter)  //Doesn't work
}

返回的对象是SoftLayer_Network_Vlan类型https://sldn.softlayer.com/reference/datatypes/softlayer_network_vlan的vlan类型数组。我能够访问列＆＃34;本地属性＆＃34;中的属性。（即名称）但我无法访问列中的属性＆＃34;关系＆amp;计数属性＆＃34; （即PrimaryRouter）。如何在调用中添加对象掩码才能看到这些属性？

Answer 1

原因是为了从API中的对象获取关系数据，你必须在API调用中声明一个对象掩码，据我所知，它没有在你的代码中声明，它应该是类似的这样：

func getPrivateVlan(env string) (string, error) {
// 1. Create a session
sess := session.New(user, pass)
// 2. Get a service
accountService := services.GetAccountService(sess)

//declare Mask
object_mask := "id;name;primaryRouter"

// 3. Invoke a method including the Object mask:
vlans, err := accountService.Mask(object_mask).GetNetworkVlans()

vlan := vlans[0]
log.Println(*vlan.Name)           //works
log.Println(*vlan.PrimaryRouter)  //
}

请尝试以下代码：

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)

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

// Object-Mask to get specific Vlan's information
mask := "id;name;primaryRouter"

// Call to getNetworkVlans in order to retrieve vlans according to filter.
result, err := service.Mask(mask).GetNetworkVlans()
if err != nil {
    fmt.Printf("\n Unable to retrieve vlans:\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))
}

F.Ojeda：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〜/ .softlayer文件的存在而导致的，因此它被配置为XMLRPC端点。

有关详细信息，请参阅以下文档：https://github.com/softlayer/softlayer-go

此问题适用于XMLRPC enpoint，您可以在go GitHub中报告它。 https://github.com/softlayer/softlayer-go/issues/

尝试使用REST端点编写代码，如下例所示：

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

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