+> 内置的`JS API`不满足需求时, 可自定义桥接信号处理
+
+
+```python
+from webengine.gtk3 import WebEngine,  create_bridge
+
+web = WebEngine()
+bridge = create_bridge() # 无需任何额外参数
+
+def bridge_handler(event, params):
+  # event 为前端 js 触发的事件名, 这里可根据不同事件名做不同的处理
+  # params 为一个 dict 字典对象, 是前端 js 传递给后端的参数
+  error = None
+  output = None
+  # ...
+  return (error, output)  # 这里必须有返回值, 且须为一个集合,  第1元素为错误信息,  当不为None时, 前端 js的调用结果, 会触发 Promise.reject() 
+
+web.use(bridge, bridge_handler) 
+web.load()
+
+```
