小程序sendDanmu方法频繁调用问题

在websocket中频繁调用sendDanmu时，数据没有问题，但是会重复显示第一条数据

wx.connectSocket({       url: `wss://${domainName}.com/ws/live/ranks?cid=${options.cid}`,       success: function(res) {         wx.showToast({           title: '连接服务器成功',         })         wx.onSocketMessage(function(res) {           var resData = JSON.parse(res.data);           if (resData.event == 'LIVE_MESSAGE') {             var dataSource = resData.data.message;             console.log(dataSource)             that.setData({               testData: dataSource             })             that.videoContext.sendDanmu({               text: dataSource.value,               color: dataSource.color             })             }         })       },       fail: function(res) {         wx.showToast({           title: '连接服务器失败',         })       }     })
