UDPSocket.bind(number port)   在开发者工具没问题，但在真机显示值为0， UDPSocket.close()也报错
this.udpSocket = uni.createUDPSocket();
				if (this.udpSocket === null) {
					console.log('暂不支持');
					return;
				}
				setTimeout(() => {
					const locationPort = this.udpSocket.bind(10012)
					console.log(locationPort);
				},1000)
				
				this.udpSocket.onListening(function(res){
					console.log('监听中.......');
					console.log(res);
				})
				this.udpSocket.onError(function(res) {
					console.log(res);
				})
				this.udpSocket.onMessage(function(res) {
					// console.log(res.message);
					let a = that.newAb2Str(res.message);
					console.log(a);
				})
