从磁盘读取/写入文件#

¥Read/Write Files from Disk

使用磁盘文件读写节点从运行 n8n 的机器读取和写入文件。

¥Use the Read/Write Files from Disk node to read and write files from/to the machine where n8n is running.

Self-hosted n8n only

此节点在 n8n Cloud 上不可用。

¥This node isn't available on n8n Cloud.

操作#

¥Operations

¥Read File(s) From Disk: Use this operation to retrieve one or more files from the computer that runs n8n.

¥Write File to Disk: Use this operation to create a binary file on the computer that runs n8n.

有关配置每个操作的节点的更多信息，请参阅以下章节。

¥Refer to the sections below for more information on configuring the node for each operation.

从磁盘读取文件#

¥Read File(s) From Disk

使用以下参数配置此操作：

¥Configure this operation with these parameters:

  • 文件选择器：输入要读取的文件的路径。

¥File(s) Selector: Enter the path of the file you want to read.

  • 要输入多个文件，请输入页面路径模式。你可以使用以下字符定义路径模式：

    ¥To enter multiple files, enter a page path pattern. You can use these characters to define a path pattern:

    • *：匹配除路径分隔符外的任何字符零次或多次。

    ¥*: Matches any character zero or more times, excluding path separators.

    • **：匹配任意字符零次或多次，包括路径分隔符。

    ¥**: Matches any character zero or more times, include path separators.

    • ?：匹配除路径分隔符外的任何字符一次。

    ¥?: Matches any character except for path separators one time.

    • []：匹配方括号内的任何字符。例如，[abc] 会匹配字符 a、b 或 c，不匹配其他任何字符。

    ¥[]: Matches any characters inside the brackets. For example, [abc] would match the characters a, b, or c, and nothing else.

有关这些字符及其预期行为的更多信息，请参阅 Picomatch 基本通配符 文档。

¥Refer to Picomatch's Basic globbing documentation for more information on these characters and their expected behavior.

从磁盘读取文件选项#

¥Read File(s) From Disk options

你还可以使用以下选项配置此操作：

¥You can also configure this operation with these Options:

  • 文件扩展名：输入节点输出中文件的扩展名。

¥File Extension: Enter the extension for the file in the node output.

  • 文件名：输入节点输出中文件的名称。

¥File Name: Enter the name for the file in the node output.

  • MIME 类型：在节点输出中输入文件的 MIME 类型。请参阅 常用 MIME 类型 获取文件扩展名及其对应的 MIME 类型列表。

¥MIME Type: Enter the file's MIME type in the node output. Refer to Common MIME types for a list of file extensions and their MIME types.

  • 将输出文件放入字段：输入输出数据中用于存储文件的字段名称。

¥Put Output File in Field: Enter the name of the field in the output data to contain the file.

将文件写入磁盘#

¥Write File to Disk

使用以下参数配置此操作：

¥Configure this operation with these parameters:

  • 文件路径和名称：请输入文件目标位置、文件名和文件扩展名。

¥File Path and Name: Enter the destination for the file, the file's name, and the file's extension.

  • 输入二进制字段：输入节点输入数据中用于存储二进制文件的字段名称。

¥Input Binary Field: Enter the name of the field in the node input data that will contain the binary file.

将文件写入磁盘选项#

¥Write File to Disk options

你还可以使用以下选项配置此操作：

¥You can also configure this operation with these Options:

此操作包含一个选项，用于选择是将数据追加到现有文件而不是创建新文件（已启用），还是创建新文件而不是追加到现有文件（已禁用）。

¥This operation includes a single option, whether to Append data to an existing file instead of creating a new one (turned on) or to create a new file instead of appending to existing (turned off).

模板和示例#

¥Templates and examples

Template widget placeholder.

文件位置#

¥File locations

如果你在 Docker 中运行 n8n，则你的命令将在 n8n 容器中运行，而不是在 Docker 主机中运行。

¥If you run n8n in Docker, your command runs in the n8n container and not the Docker host.

此节点会查找相对于 n8n 安装路径的文件。n8n 建议使用绝对文件路径以避免任何错误。

¥This node looks for files relative to the n8n install path. n8n recommends using absolute file paths to prevent any errors.
