【转】gophercloud 不错的openstack golang sdk

原文: https://www.cnblogs.com/rongfengliang/p/14069237.html

---------------------------

gophercloud 是一个基于golang 包装的openstack api，功能比较强大，使用上也很不错，同时也提供了比较完备的参考资料

一个参考使用demo

package main

​

import (

    "log"

​

    "github.com/gophercloud/gophercloud"

    "github.com/gophercloud/gophercloud/openstack"

    "github.com/gophercloud/gophercloud/openstack/compute/v2/servers"

    "github.com/gophercloud/gophercloud/pagination"

)

​

func main() {

​

    // 1. ops

    authOpts := gophercloud.AuthOptions{

        IdentityEndpoint: "https://openstack.example.com:5000/v2.0",

        Username:         "{username}",

        Password:         "{password}",

    }

    // 2. provider

    provider, err := openstack.AuthenticatedClient(authOpts)

    if err != nil {

        log.Fatal("some wrong", err.Error())

    }

    // 3. different ops (compute,block-storage,identity,networking,object-storage。。。。)

    client, err := openstack.NewComputeV2(provider, gophercloud.EndpointOpts{

        Region: "RegionOne",

    })

​

    // 4. servers ops

    opts := servers.ListOpts{Name: "server_1"}

    // Retrieve a pager (i.e. a paginated collection)

    pager := servers.List(client, opts)

​

    // page for fetch serverList

    err = pager.EachPage(func(page pagination.Page) (bool, error) {

        serverList, err := servers.ExtractServers(page)

        if err != nil {

            log.Println("some wrong:", err.Error())

            return false, err

        }

        for _, s := range serverList {

            log.Println(s)

        }

        return true, nil

    })

​

}
