ComfyUI Node: 加载文件(load_file)

加载文件(load_file):

The load_file node is designed to read the contents of a specified file and return it as a string. This node is particularly useful for AI artists who need to load text data from files for further processing or analysis. By providing a simple interface to read files, it helps streamline workflows that involve text data, making it easier to integrate file content into your projects. The node can handle both absolute and relative file paths, and it includes an option to enable or disable the file loading functionality, offering flexibility and control over its operation.

加载文件(load_file) Input Parameters:

path

This parameter specifies the path to the file you want to load. It can be either an absolute path or a relative path, depending on the path_type parameter. The default value is "test.txt". If you choose a relative path, it will be relative to the directory where the script is located.

path_type

This parameter determines whether the path parameter is treated as an absolute path or a relative path. It accepts two options: "Absolute_Path" and "Relative_Path", with the default being "Relative_Path". This allows you to specify how the file path should be interpreted.

is_enable

This boolean parameter controls whether the file loading functionality is enabled. If set to False, the node will not attempt to load the file and will return None. The default value is True, meaning the file loading is enabled by default.

加载文件(load_file) Output Parameters:

file_content

This output parameter contains the content of the loaded file as a string. If the file loading is disabled (is_enable is False), this parameter will be None. Otherwise, it will contain the text data read from the specified file.

加载文件(load_file) Usage Tips:

• Ensure that the path parameter is correctly set to the file you want to load. If using a relative path, make sure it is relative to the script's directory.
• Use the is_enable parameter to control whether the file should be loaded, which can be useful for conditional workflows where file loading is not always required.
• Verify the path_type parameter to ensure the file path is interpreted correctly, especially when working with different directory structures.

加载文件(load_file) Common Errors and Solutions:

FileNotFoundError

• Explanation: This error occurs when the specified file path does not exist.
• Solution: Check the path parameter to ensure it points to a valid file. Verify whether the path is absolute or relative and adjust the path_type parameter accordingly.

PermissionError

• Explanation: This error occurs when the script does not have the necessary permissions to read the specified file.
• Solution: Ensure that the file permissions allow reading by the script. You may need to adjust the file permissions or run the script with elevated privileges.

ValueError: Invalid path_type

• Explanation: This error occurs when an invalid value is provided for the path_type parameter.
• Solution: Ensure that the path_type parameter is set to either "Absolute_Path" or "Relative_Path". Any other value will cause this error.

NoneType returned

• Explanation: This occurs when is_enable is set to False, resulting in no file being loaded.
• Solution: Set the is_enable parameter to True if you want to load the file content.
