使用Ajax请求
Python
@app.route('/_stuff', methods= ['GET'])
def stuff():
cpu=round(getcpuLoad())
ram=round(getVmem())
disk=round(getDisk())
return jsonify(cpu=cpu, ram=ram, disk=disk)
Javascript
function update_values() {
$SCRIPT_ROOT = {{ request.script_root|tojson|safe }};
$.getJSON($SCRIPT_ROOT+"/_stuff",
function(data) {
$("#cpuload").text(data.cpu+" %")
$("#ram").text(data.ram+" %")
$("#disk").text(data.disk+" %")
});
}
使用Websockets
project/app/views/request/websockets.py
# -*- coding: utf-8 -*-
# OS Imports
import json
# Local Imports
from app import sockets
from app.functions import get_cpu_load, get_disk_usage, get_vmem
@sockets.route('/_socket_system')
def socket_system(ws):
"""
Returns the system informations, JSON Format
cpu, RAM, and Disk Usage
"""
while True:
message = ws.receive()
if message == "update":
cpu = round(get_cpu_load())
ram = round(get_vmem())
disk = round(get_disk_usage())
ws.send(json.dumps(dict(received=message, cpu=cpu, ram=ram, disk=disk)))
else:
ws.send(json.dumps(dict(received=message)))
project/app/__init__.py
# -*- coding: utf-8 -*-
from flask import Flask
from flask_sockets import Sockets
app = Flask(__name__)
sockets = Sockets(app)
app.config.from_object('config')
from app import views
使用Flask-Websockets使我的生活更加轻松。这是启动器： launchwithsockets.sh
#!/bin/sh
gunicorn -k flask_sockets.worker app:app
请注意，我没有使用socket.io之类的东西，这就是代码很长的原因。此代码还尝试定期重新连接到服务器，并且可以停止尝试通过用户操作重新连接。我使用Messenger库来通知用户出现问题。当然，这比使用socket.io要复杂一些，但是我非常喜欢对客户端进行编码。
