python服务器同web端进行 websocket传输
1.python服务器端：
1）主函数中写入websocket启动
t = threading.Thread(target=startWebsocketServer)
t.start()
2）服务器信息
def startWebsocketServer():
global server
def new_client(client, server):
print(server)
# server.send_message_to_all("Hey all, a new client has joined us")
def mysend(client,server,msg):
print(msg)
server.send_message(client,"哈哈哈哈哈")
if(msg == "_end"): #如果收到了_end 消息，那么断开连接
server.server_close()
//写出端口号
server = WebsocketServer(port=30031, host='0.0.0.0')
server.set_fn_new_client(new_client)
server.set_fn_message_received(mysend)
server.run_forever()
server.server_close()
2）服务器发送写法
server.send_message_to_all(disasterInfo)
3.web端接收
var websocket = null;
if ('WebSocket' in window) {
// 获取服务器地址
websocket = new WebSocket('ws://localhost:30031');
} else {
alert("浏览器不支持WebSocket");
}
//打开
websocket.onopen = function (event) {
console.log('建立连接');
}
websocket.onclose = function (event) {
console.log('连接关闭');
}
websocket.onmessage = function (event) {
console.log(event.data);
//由于只能以字符串形式发送，以；作为分隔，获取对应数据
var rsArr = event.data.split(";")
console.log(rsArr);
if (rsArr[0] == "position") {
var username = rsArr[1];
var x = rsArr[2];
var y = rsArr[3];
var areaId = rsArr[4];
var time = rsArr[5];
console.log(username);
}
}
websocket.onerror = function (event) {
//alert('通讯错误');
}
window.onbeforeunload = function () {
websocket.close();
}
