写在后面接上篇，上篇分享了openstack的api应用套路，本篇分享vmware的api应用套路，心愿能够帮忙到有须要的盆友。在观看本文之前，也是最重要的一点，就是请确保你曾经搭建好了用于测试的vsphere环境（esxi和vcenter）。
我的测试环境：
API文档浏览套路&实战首次浏览vsphere api文档的话，可能会有点懵，上面我把最须要关注的点，以及浏览套路给说分明，搞明确之后，其实也都够用了。官网API文档： https://developer.vmware.com/...
1. 对于vsphere的能力，咱们更关注的是vSphere Web Services API
2. 依据vsphere版本抉择绝对应的API版本
3. 对象类型
如上图，All Types蕴含了上面几种类型，只是做了分类而已：
Managed Object TypesData Object TypesEnumerated TypesFault TypesManaged Object Types是最罕用的，有虚拟机（VirtualMachine）、存储（Datastore）、宿主机（HostSystem）、网络（Network）等等，那平时怎么应用它呢？假如，当失去一个虚拟机实例对象时，想晓得它都能获取到什么属性，那么就能够在Property进行查阅。![图片]()
还有一个特地留神的中央，就是vim.VirtualMachine，它其实是某种对象类型的示意办法或者说是标识。比方，应用python的pyvmomi库，就须要指定查找的对象类型。如果是应用go，则是指定"VirtualMachine"应用Go编码，获取虚拟机属性：
package mainimport ( "context" "flag" "fmt" "log" "net/url" "os" "strings" "github.com/vmware/govmomi/session/cache" "github.com/vmware/govmomi/simulator" "github.com/vmware/govmomi/view" "github.com/vmware/govmomi/vim25" "github.com/vmware/govmomi/vim25/mo" "github.com/vmware/govmomi/vim25/soap")func getEnvString(v string, def string) string { r := os.Getenv(v) if r == "" { return def } return r}func getEnvBool(v string, def bool) bool { r := os.Getenv(v) if r == "" { return def } switch strings.ToLower(r[0:1]) { case "t", "y", "1": return true } return false}const ( envURL = "GOVMOMI_URL" envUserName = "GOVMOMI_USERNAME" envPassword = "GOVMOMI_PASSWORD" envInsecure = "GOVMOMI_INSECURE")var urlDescription = fmt.Sprintf("ESX or vCenter URL [%s]", envURL)var urlFlag = flag.String("url", getEnvString(envURL, ""), urlDescription)var insecureDescription = fmt.Sprintf("Don't verify the server's certificate chain [%s]", envInsecure)var insecureFlag = flag.Bool("insecure", getEnvBool(envInsecure, false), insecureDescription)func processOverride(u *url.URL) { envUsername := os.Getenv(envUserName) envPassword := os.Getenv(envPassword) if envUsername != "" { var password string var ok bool if u.User != nil { password, ok = u.User.Password() } if ok { u.User = url.UserPassword(envUsername, password) } else { u.User = url.User(envUsername) } } if envPassword != "" { var username string if u.User != nil { username = u.User.Username() } u.User = url.UserPassword(username, envPassword) }}func NewClient(ctx context.Context) (*vim25.Client, error) { u, err := soap.ParseURL(*urlFlag) if err != nil { return nil, err } processOverride(u) s := &cache.Session{ URL: u, Insecure: *insecureFlag, } c := new(vim25.Client) err = s.Login(ctx, c, nil) if err != nil { return nil, err } return c, nil}func Run(f func(context.Context, *vim25.Client) error) { flag.Parse() var err error var c *vim25.Client if *urlFlag == "" { err = simulator.VPX().Run(f) } else { ctx := context.Background() c, err = NewClient(ctx) if err == nil { err = f(ctx, c) } } if err != nil { log.Fatal(err) }}const ( vimVirtualMachine = "VirtualMachine")func a(ctx context.Context, c *vim25.Client) error { m := view.NewManager(c) v, err := m.CreateContainerView(ctx, c.ServiceContent.RootFolder, []string{vimVirtualMachine}, true) if err != nil { return err } defer v.Destroy(ctx) var vms []mo.VirtualMachine err = v.Retrieve(ctx, []string{vimVirtualMachine}, []string{"summary"}, &vms) if err != nil { return err } for _, vm := range vms { fmt.Println(vm.Summary.Guest.HostName, vm.Summary.Runtime.PowerState) } return nil}func main() { Run(a)}设置好环境变量：
export GOVMOMI_URL="192.168.11.104"export GOVMOMI_USERNAME="administrator@vsphere.local"export GOVMOMI_PASSWORD="1qaz#EDC"export GOVMOMI_INSECURE="y"测试运行并输入后果：
[root@devhost vmware]# go run coll-vsphere.go 192.168.11.104 poweredOnphoton3-hdcs poweredOn应用Python编码，获取虚拟机属性：

[root@devhost cloud-collect]# /usr/local/python2.7.13/bin/python vmcollect.py 192.168.11.104photon3-hdcs4. 办法持续拿VirtualMachine对象来看看它都有哪些办法，通过文档可看到虚拟机对象反对很多办法，创立、克隆、开机、关机、增加磁盘、增加网卡等等。每一个办法都详细描述了所须要的参数。在每个具体的对象类型中，都形容了所反对的办法，这些办法也能够在“All Methods”里查到。
上面应用Python编码，从模板克隆虚构，代码如下：
