1.种植园使用websocket代替http
我们需要完成的种植园，是一个互动频繁，并且要求有一定即时性的模块，所以如果继续基于http协议开发，那么需要通过ajax发送大量http请求，同时因为http本身属于单向通讯，所以服务端无法主动发送信息提供给客户端。所以对于客户端使用来说，非常不友好，所以我们需要基于socket通讯来完成这个模块的开发。当然，如果我们服务端基于socket实现tcp/ip通讯的同时，那么客户端必须也要使用websocket来实现tcp/ip通讯才能正常运作。
1.websocket协议简介
文档：https://tools.ietf.org/html/rfc6455
一直以来，HTTP是无状态、单向通信的网络协议，即客户端请求一次，服务器回复一次，默认情况下，只允许浏览器向服务器发出请求后，服务器才能返回相应的数据。如果想让服务器消息及时下发到客户端，需要采用类似于轮询的机制，大部分情况就是客户端通过定时器使用ajax频繁地向服务器发出请求。这样的做法效率很低，而且HTTP数据包头本身的字节量较大，浪费了大量带宽和服务器资源。
为了提高效率，HTML5推出了WebSocket技术。
WebScoket是一种让客户端和服务器之间能进行全双工通信(full-duplex)的技术。它是HTML最新标准HTML5的一个协议规范，本质上是个基于TCP的协议，它通过HTTP/HTTPS协议发送一条特殊的请求进行握手后创建了一个TCP连接，此后浏览器/客户端和服务器之间便可随时随地以通过此连接来进行双向实时通信，且交换的数据包头信息量很小。
同时为了方便使用，HTML5提供了非常简单的操作就可以让前端开发者直接实现socket通讯，开发者只需要在支持WebSocket的浏览器中，创建Socket之后，通过onopen、onmessage、onclose、onerror四个事件的实现即可处理Socket的响应。
注意：websocket是HTML5技术的一部分，但是websocket并非只能在浏览器或者HTML文档中才能使用，事实上在python或者C++等语言中只要能实现websocket协议报文，均可使用。
导读：https://blog.csdn.net/zhusongziye/article/details/80316127
客户端报文
GET /mofang/websocket HTTP/1.1
Host: 127.0.0.1
Origin: http://127.0.0.1:5000
Upgrade: websocket
Connection: Upgrade
Sec-WebSocket-Key: sN9cRrP/n9NdMgdcy2VJFQ== # Sec-WebSocket-Key 是随机生成的
Sec-WebSocket-Version: 13
服务端报文
HTTP/1.1 101 Switching Protocols
Upgrade: websocket
Connection: Upgrade
Sec-WebSocket-Accept: HSmrc0sMlYUkAGmm5OPpG2HaGWk= # 结合客户端提供的Sec-WebSocket-Key基于固定算法计算出来的
Sec-WebSocket-Protocol: chat
2.WebSocket与Socket的关系
他们两的关系就像Java和JavaScript，并非完全没有关系，只能说有点渊源。
Socket严格来说，其实并不是一个协议，而是为了方便开发者使用TCP或UDP协议而对TCP/IP协议进行封装出来的一组接口，是位于应用层和传输控制层之间的接口。通过Socket接口，我们可以更简单，更方便的使用TCP/IP协议。
WebSocket是实现了浏览器与服务器的全双工通信协议，一个模拟Socket的应用层协议。
2.服务端基于socket提供服务
1.安装并配置flask-socketio
在python中实现socket服务端的方式有非常多，一种最常用的有python-socketio，而我们现在使用的flask框架也有一个基于python-socket模块进行了封装的flask-socketio模块.
官方文档：https://flask-socketio.readthedocs.io/en/latest/
注意:
因为目前还有会存在一小部分的设备或者应用是不支持websocket的.所以为了保证功能的可用性,我们使用socektio,但是由此带来了2个问题,必须要注意的:
python服务端使用基于socketio进行通信服务,则另一端必须也是基于socetio来进行对接通信,否则无法进行通信
socketio还有一个版本对应的问题, 版本不对应则无法通信.回报版本错误.
如果使用了javascript io 1.x或者2.x版本,则python-socketio或者flask-socketio的版本必须是4.x
如果使用了javascriptio 3.x版本,则python-socketio或者flask-socketio的版本必须是5.x.
我们当前使用的flask-socketio版本是5.x,所以javasctipt的socketio版本就必须是3.x.
终端下执行命令，安装：
pip install flask-socketio
pip install gevent-websocket
模块初始化，application/__init__.py，代码：
from flask_socketio import SocketIO # socketio
socketio = SocketIO() def init_app(config_path):
"""全局初始化""" # socketio
socketio.init_app(app, cors_allowed_origins=app.config["CORS_ALLOWED_ORIGINS"],async_mode=app.config["ASYNC_MODE"], debug=app.config["DEBUG"])
# 改写runserver命令
if sys.argv[1] == "runserver":
manager.add_command("run", socketio.run(app,host=app.config["HOST"],port=app.config["PORT"]))
配置文件,application/settings/dev.py,代码:
# socketio
CORS_ALLOWED_ORIGINS="*"
ASYNC_MODE=None
HOST="0.0.0.0"
PORT=5000
application/utils/__init__.py，在加载蓝图的过程中，自动加载socket服务端的api，代码：
def init_blueprint(app):
"""自动注册蓝图"""
......
# 加载蓝图内部的socket接口
try:
import_module(blueprint_path+".socket")
except:
pass
2.客户端引入socket.io.js
因为我们是基于python-socketio模块提供的服务端，所以客户端必须基于socketIO.js才能与其进行通信，所以客户端引入socketio.js。
socket.io.js的官方文档: https://socket.io/docs/v3
socket.io.js的github: https://github.com/socketio/socket.io/releases
我们可以新建一个orchard.html作为将来种植园模块的主页面，并在这个页面中使用socketio和服务端的flask-socketIO进行通信。
代码：
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title></title>
<script type="text/javascript" src="../static/js/socket.io.js"></script>
</head>
<body> <script>
// 命名空间
namespace = '/mofang';
var socket = io.connect('ws://192.168.20.251:5000' + namespace, {transports: ['websocket']});
// socket.on('connect', function() {
// console.log("客户端连接socket服务端");
// });
</script>
</body>
</html>
3.服务端创建orchard蓝图
服务端创建并注册蓝图目录orchard，终端命令如下：
cd application/apps/
python ../../manage.py blue -n=orchard
application/urls.py，代码：
from application.utils import include
urlpatterns = [
include("","home.urls"),
include("/users","users.urls"),
include("/marsh","marsh.urls"),
include("/orchard","orchard.urls"),
applicaion/settings/dev.py，代码:
# 注册蓝图
INSTALLED_APPS = [
"application.apps.home",
"application.apps.users",
"application.apps.marsh",
"application.apps.orchard",
]
4.创建socket连接
在蓝图下面创建socket.py文件，并提供连接接口, orchard/socket.py：
from application import socketio
from flask import request
@socketio.on("connect", namespace="/mofang")
def user_connect():
# request.sid socketIO基于客户端生成的唯一会话ID
print("用户%s连接过来了!" % request.sid) @socketio.on("disconnect", namespace="/mofang")
def user_disconnect():
print("用户%s退出了种植园" % request.sid )
5.客户端vue结合socketio

// ***通过send方法可以直接发送数据,不需要自定义事件,数据格式是json格式***
this.socket.send({"uid":id});
},
go_index(){
this.game.outWin("orchard");
},
}
});
}
</script>
</body>
</html>
基于未定义事件进行通信
服务端orchard/socket.py代码:
from application import socketio
from flask import request # 未定义事件通信，客户端没有指定事件名称
@socketio.on("message",namespace="/mofang")
def user_message(data):
print("接收到来自%s发送的数据:" % request.sid)
print(">>>>data:",data)
print(">>>>uid:"data["uid"])

// **自定义事件用emit提交**
this.socket.emit("login",{"uid":id});
},
go_index(){

def user_login(data):
print("接受来自客户端%s发送的数据:" % request.sid)
print(data)
print(data["uid"])
3.服务端响应信息
1.服务端响应信息给客户端
服务端通过socketio.emit将内容响应给客户端
from application import socketio
from flask import request
from application.apps.users.models import User
# 建立socket通信
@socketio.on("connect", namespace="/mofang")
def user_connect():
# request.sid socketIO基于客户端生成的唯一会话ID
print("用户%s连接过来了!" % request.sid) # ***主动响应数据给客户端***
length = User.query.count()
socketio.emit("server_response",{"count":length},namespace="/mofang")
客户端接收响应信息,orchard.html代码:
