SharePoint Online和OneDrive for Business支持版本控制，可以保留文件的版本历史，方便用户随时查看和恢复以前的版本。但该功能也会占用大量SharePoint Online或OneDrive for Business存储空间。官方删除版本历史的方法无法批量操作，故今天提供一种使用Power Automate来删除SharePoint Online或OneDrive for Business文件版本历史。
第一步：添加“Get files(properties only)”操作，以获取列表中的文件。
第二步：添加“Send an HTTP request to SharePoint”操作：
Method: GET
Uri: _api/web/GetFolderByServerRelativeUrl('Dynamic content of Folder Path')/Files('Dynamic content of File name with extension')/Versions
第三步：“Parse JSON”，将上一个动作的正文放入解析 JSON 动作的内容中，然后点击“使用示例负载”按钮生成 schema 粘贴如下 schema：
{
"type": "object",
"properties": {
"d": {
"type": "object",
"properties": {
"results": {
"type": "array",
"items": {
"type": "object",
"properties": {
"__metadata": {
"type": "object",
"properties": {
"id": {
"type": "string"
},
"uri": {
"type": "string"
},
"type": {
"type": "string"
}
}
},
"CreatedBy": {
"type": "object",
"properties": {
"__deferred": {
"type": "object",
"properties": {
"uri": {
"type": "string"
}
}
}
}
},
"CheckInComment": {
"type": "string"
},
"Created": {
"type": "string"
},
"ID": {
"type": "integer"
},
"IsCurrentVersion": {
"type": "boolean"
},
"Length": {
"type": "string"
},
"Size": {
"type": "integer"
},
"Url": {
"type": "string"
},
"VersionLabel": {
"type": "string"
}
},
"required": [
"__metadata",
"CreatedBy",
"CheckInComment",
"Created",
"ID",
"IsCurrentVersion",
"Length",
"Size",
"Url",
"VersionLabel"
]
}
}
}
}
}
}
第四步：创建另一个“Send an Http request to SharePoint”：
Method: DELETE
Uri: _api/web/GetFolderByServerRelativeUrl('Dynamic content of Folder Path')/Files('Dynamic content of File name with extension')/Versions(ID from the previous action)
