可通过importlib动态执行python代码,示例如下:
mport importlib.util
PLUGIN_DIR = 'plugin'
def load_plugin(plugin_path,plugin_name):
spec = importlib.util.spec_from_file_location(plugin_name, plugin_path)
module = importlib.util.module_from_spec(spec)
spec.loader.exec_module(module)
return module
def run_plugin(plugin_name,paras):
plugin_file=os.path.join(plugin_name, "run.py")
try:
plugin = load_plugin(os.path.join(PLUGIN_DIR, plugin_file),plugin_name)
output=plugin.run(paras)
return output
print(f"Output from {plugin_name}: {output}")
except Exception as e:
print(f"Error executing plugin {plugin_name}: {e}")
return None
run_plugin("getnowdate",{}):
插件代码,例如plugin/getnowdate/run.py
from datetime import datetime
def run(paras):
now = datetime.now()
current_date = now.strftime("%Y-%m-%d")
current_time = now.strftime("%H:%M:%S")
print("Plugin 2 is running")
return f"当前日期: {current_date} {current_time}" 网友回复
