帮我写一个django 按钮点击后让虚拟机开机

好的，以下是一个简单的Django视图函数，它可以在按钮点击后让虚拟机开机：

from django.shortcuts import render
from django.http import HttpResponse
from pyVim import connect
from pyVmomi import vim

def power_on_vm(request):
    # 获取POST请求中的虚拟机名称、用户名和密码
    vm_name = request.POST.get('vm_name')
    vm_username = request.POST.get('vm_username')
    vm_password = request.POST.get('vm_password')
    
    # 连接到vCenter服务器
    service_instance = connect.SmartConnectNoSSL(host='vcenter_server_ip', user='vcenter_username', pwd='vcenter_password')

    # 查找虚拟机对象
    content = service_instance.RetrieveContent()
    container = content.viewManager.CreateContainerView(content.rootFolder, [vim.VirtualMachine], True)
    vm_object = next((vm for vm in container.view if vm.name == vm_name), None)
    container.Destroy()

    # 开机虚拟机
    if vm_object:
        power_state = vm_object.runtime.powerState
        if power_state == vim.VirtualMachinePowerState.poweredOff:
            print(f"Powering on {vm_name}...")
            task = vm_object.PowerOnVM_Task()
            # 等待任务完成
            while task.info.state not in [vim.TaskInfo.State.success, vim.TaskInfo.State.error]:
                pass
            if task.info.state == vim.TaskInfo.State.success:
                print(f"{vm_name} has been powered on successfully.")
                return HttpResponse("Virtual machine has been powered on successfully.")
            else:
                print(f"Failed to power on {vm_name}.")
                return HttpResponse("Failed to power on virtual machine.")
        else:
            print(f"{vm_name} is already powered on.")
            return HttpResponse("Virtual machine is already powered on.")
    else:
        print(f"Virtual machine {vm_name} not found.")
        return HttpResponse("Virtual machine not found.")

在上面的代码中，`power_on_vm()`函数将从POST请求中获取虚拟机名称、用户名和密码，并使用pyVmomi库连接到vCenter服务器。接下来，它将查找虚拟机对象，并使用`PowerOnVM_Task()`方法开机虚拟机。如果虚拟机成功开机，函数将返回一个包含成功消息的HTTP响应。如果虚拟机已经处于开机状态或无法找到虚拟机对象，则函数将返回相应的HTTP响应。请注意，你需要将`vcenter_server_ip`、`vcenter_username`和`vcenter_password`替换为你自己的vCenter服务器的IP地址、用户名和密码。
