Qgis 自動clips with 2 layer in a batch files

To perform batch clipping in QGIS using Python, you can use the following code:

import os
from qgis.core import QgsVectorLayer, QgsClipper

# Set the source directory containing the layers to be clipped
src_dir = '/path/to/source/directory/'

# Set the destination directory for the clipped layers
dst_dir = '/path/to/destination/directory/'

# Set the clipping layer
clip_layer = QgsVectorLayer('/path/to/clip/layer.shp', 'clip_layer', 'ogr')

# Loop through the files in the source directory
for filename in os.listdir(src_dir):
    if filename.endswith('.shp'):
        # Load the layer to be clipped
        layer = QgsVectorLayer(os.path.join(src_dir, filename), filename[:-4], 'ogr')
        # Perform the clip operation
        result = processing.run('native:clip', {
            'INPUT': layer,
            'OVERLAY': clip_layer,
            'OUTPUT': os.path.join(dst_dir, filename)
        })

In this code, you need to replace the following:
- `src_dir`: The path to the directory containing the layers to be clipped.
- `dst_dir`: The path to the directory where the clipped layers will be saved.
- `clip_layer`: The path to the layer that will be used to clip the other layers.

Save this code as a Python file (e.g., `batch_clip.py`) and run it in the QGIS Python Console or in a terminal using the `qgis_process` command.
