好的,我可以给你提供一个简单的Django视图函数,可以让你在点击按钮后开机一个指定的虚拟机。
首先,你需要安装PyVmomi模块来管理VMware虚拟机。你可以使用以下命令来安装它:
```bash
pip install pyvmomi
```
接下来,你可以使用以下代码来编写一个Django视图函数:
```python
from django.shortcuts import render
from django.http import HttpResponse
from pyVim import connect
from pyVmomi import vim
def power_on_vm(request):
# 从POST请求中获取虚拟机名称、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 Server
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模块连接到vCenter Server。然后,它会查找指定名称的虚拟机对象,并通过调用`PowerOnVM_Task()`方法将其开机。
最后,`power_on_vm()`函数将返回一个包含成功或失败消息的HTTP响应。
你可以将上面的代码添加到你的Django项目中,并在视图中使用它来处理按钮点击事件。
