+10: socket.io 相关
+
+官网：https://socket.io
+
+import { createServer } from "http";
+import { Server } from "socket.io";
+
+const httpServer = createServer();
+const io = new Server(httpServer);
+
+io.on("connection", (socket) => {
+  
+});
+
+httpServer.listen(3000);
+
+事件大全：https://socket.io/docs/v4/emit-cheatsheet/
+io.on("connection", (socket) => {
+
+  // basic emit
+  socket.emit(/* ... */);
+
+  // to all clients in the current namespace except the sender
+  socket.broadcast.emit(/* ... */);
+
+  // to all clients in room1 except the sender
+  socket.to("room1").emit(/* ... */);
+
+  // to all clients in room1 and/or room2 except the sender
+  socket.to(["room1", "room2"]).emit(/* ... */);
+
+  // to all clients in room1
+  io.in("room1").emit(/* ... */);
+
+  // to all clients in room1 and/or room2 except those in room3
+  io.to(["room1", "room2"]).except("room3").emit(/* ... */);
+
+  // to all clients in namespace "myNamespace"
+  io.of("myNamespace").emit(/* ... */);
+
+  // to all clients in room1 in namespace "myNamespace"
+  io.of("myNamespace").to("room1").emit(/* ... */);
+
+  // to individual socketid (private message)
+  io.to(socketId).emit(/* ... */);
+
+  // to all clients on this node (when using multiple nodes)
+  io.local.emit(/* ... */);
+
+  // to all connected clients
+  io.emit(/* ... */);
+
+  // WARNING: `socket.to(socket.id).emit()` will NOT work, as it will send to everyone in the room
+  // named `socket.id` but the sender. Please use the classic `socket.emit()` instead.
+
+  // with acknowledgement
+  socket.emit("question", (answer) => {
+    // ...
+  });
+
+  // without compression
+  socket.compress(false).emit(/* ... */);
+
+  // a message that might be dropped if the low-level transport is not writable
+  socket.volatile.emit(/* ... */);
+});

+11：获取键盘高度
+更新：https://uniapp.dcloud.io/component/input
+新版已经补充了键盘高度，在弹出键盘时@focus，有event.detail = { value, height }，height 为键盘高度。
+
+关闭键盘
+uni.hideKeyboard()
