Syntax
语法
CopyRecord(src,dest,username,psword,opt,async) MoveRecord(src,dest,username,psword,opt,async) |
| Parameter参数 | Description描述 |
|---|---|
| src | Optional. The URL of the file or directory that will be copied/moved 可选参数。指示需要被复制/移动的文件或目录的URL |
| dest | Optional. The URL to the location where src will be copied/moved 可选参数。指示需要将src复制/移动到具体地点的URL |
| username | Optional. The user ID that authorizes access to dest 可选参数。访问dest的授权用户ID |
| psword | Optional. The password that verifies username 可选参数。访问dest的授权用户密码 |
| opt | For CopyRecord: Optional. A CopyRecordOptionsEnum value that specifies the behavior of this method. Default is adCopyUnspecified CopyRecord:可选参数。用于指定Method[方法]具体特性的一个CopyRecordOptionsEnum值。默认值为adCopyUnspecified For MoveRecord: Optional. A MoveRecordOptionsEnum value that specifies the behavior of this method. Default is adMoveUnspecified |
| async | Optional. A Boolean value that, when True, sets this operation to be asynchronous 可选参数。指定一个逻辑值。当为True时，设操作进程设置为不同步操作 |
CopyRecordOptionsEnum Values
| Constant 常量 | Value 值 | Description 描述 |
|---|---|---|
| adCopyUnspecified | -1 | Default. Will not allow over write or recursive copy 默认值。不允许覆盖或递归复制 |
| adCopyOverWrite | 1 | Overwrites the file/directory if it already exists 允许覆盖现有的文件/目录 |
| adCopyNonRecursive | 2 | Copies the current directory (none of its subdirectories) to the destination (this operation is not recursive) 将当前目录（其子目录除外）复制到目标目录（该项操作是不可递归的） |
| adCopyAllowEmulation | 4 | Requests that the provider attempt to simulate the copy. If the attempt to copy the Record fails because the destination URL is on a different server or serviced by a different provider than the source, this may cause data loss 请求技术提供对象[provider]尝试伪复制。如果记录复制失败，说明目标URL位于不同的服务器，或者是由不同的技术提供对象[provider]提供服务的，这可能导致数据丢失 |
MoveRecordOptionsEnum Values
| Constant 常量 | Value 值 | Description 描述 |
|---|---|---|
| adMoveUnspecified | -1 | Default. Will not overwrite any file/ directory at the destination location. Will also update links 默认值。不可以覆盖目标地址中任何一个文件/目录，但仍可以更新连接 |
| adMoveOverWrite | 1 | Overwrites the file/directory if it already exists 允许覆盖现有的文件/目录 |
| adMoveDontUpdateLinks | 2 | Modifies the default behavior of MoveRecord method by not updating the links of the source Record. The default behavior depends on the capabilities of the provider 不通过更新源记录的连接而对MoveRecord的默认特性进行修改。该默认特性是由技术提供对象[provider]的具体功能决定的 |
| adMoveAllowEmulation | 4 | Requests that the provider attempt to simulate the move. If the attempt to move the Record fails because the destination URL is on a different server or serviced by a different provider than the source, this may cause data loss 请求技术提供对象[provider]尝试伪复制。如果记录复制失败，说明目标URL位于不同的服务器，或者是由不同的技术提供对象[provider]提供服务的，这可能导致数据丢失 |
