连接soket之后，调用任何请求，socket的onOpen 都会在执行一次；我是通过 返回的 实例 进行回调注册的

const SocketTask = (this.SocketTask = wx.connectSocket({

url: ‘x’,

}));

SocketTask.onOpen(msg => {

console.log(‘onOpen’, msg);

//

SocketTask.send({

data: JSON.stringify({

scene: ‘shake_hands’,

openid: userInfo.openid,

uniacid: userInfo.uniacid,

}),

});

});

SocketTask.onClose(msg => {

console.log(‘onCloase’, msg);

});

SocketTask.onMessage(data => {

store.eventBus.emit(‘getSocketMsg’, data);

});
