美好的一天！
我正在尝试自动执行一些要对我组织中的虚拟机执行的操作。 要执行的操作取决于 VM 名称中的 a 子字符串。
例如，我需要删除所有名称以“delete”开头的虚拟机，等等。
我可以使用以下 API 来获取 VM 列表：
GET https://{{vc}}/rest/vcenter/vm
但是，此 API 最多只能获取 1000 个 VM。
有什么方法可以过滤并仅获取来自该 API 的带有预期子字符串的 VM 列表？
据我了解，将 filter.names.1 附加到上述 API 是可行的，但为此我需要输入准确的完整 VM 名称。
有没有一种方法可以搜索带有部分文本的 VM 列表？
抱歉，我是新手。
感谢您的宝贵时间！

Since vSphere API does not provide such capability to search by partial VM name there is a tricky way to do this.
I am using the search functionality in vSphere Client 6.7.0.
Prerequisite is to get the following cookies first:
VSPHERE-USERNAME
VSPHERE-CLIENT-SESSION-INDEX
VSPHERE-UI-JSESSIONID
You have to do three calls in order to get them:
1. GET "https://[URL]/ui/login" you will be forwarded to a new URL from where you can take "SAMLRequest token"
2. POST "https://[URL]/websso/SAML2/SSO/vsphere.local?SAMLRequest=[SAMLRequest token]", set as header "CastleAuthorization=Basic%20[credentials]" where credentials is the Base64 encoding of "User:Password". Get the value of "SAMLResponse" hidden field from the response.
3. POST "https://[URL]/ui/saml/websso/sso", set "SAMLResponse=[SAMLResponse value]", where "SAMLResponse value" you have it from the previous response. From this response you will get the cookies.
Once you have those three cookies, make a new call as you set the cookies
4. GET "https://[URL]/ui/search/quicksearch/?opId=0&query=[partial VM name]"
For example for this call "https://[URL]/ui/search/quicksearch/?opId=0&query=test"
you will get response like this:
[{
"icon": "vsphere-icon-vm",
"labelPlural": "Virtual Machines",
"label": "Virtual Machine",
"results": [{
"id": "urn:vmomi:VirtualMachine:vm-2153:103ac083-e314-47ea-942a-c685d9a4e6c9",
"type": "VirtualMachine",
"name": "TestVM1"
}, {
"id": "urn:vmomi:VirtualMachine:vm-3391:103ac083-e314-47ea-942a-c685d9a4e6c9",
"type": "VirtualMachine",
"name": "TestVM2"
}, {
"id": "urn:vmomi:VirtualMachine:vm-3438:103ac083-e314-47ea-942a-c685d9a4e6c9",
"type": "VirtualMachine",
"name": "TestVM3"
}
]
}
]

【讨论】：
不幸的是，vSphere 自动化 API 未设置为过滤部分名称，甚至在使用通配符时也未设置。一些可用的过滤器可以帮助您将输出限制在 1000 个对象限制以下（例如：过滤特定的集群和/或文件夹）。
希望这是在未来版本中添加的内容。
