Python基础之数字化大屏
在公司内部或前台，有时需要展示数字化看板，展示公司的业务信息。看着别的公司展示的炫酷的数字化大屏，是否很羡慕？本文以Python+flask+jQuery+eCharts，简述如何开发数字化大屏进行数据展示，仅供学习分享使用，如有不足之处，还请指正。
涉及知识点
- Python+flask开发web系统，实现数据传输。
- jQuery通过ajax技术，实现数据的异步通信，局部刷新。
- eCharts进行图表的展示（包括柱状图，折线图，地图等）。
- html+css页面布局等技术。
示例效果图
在本例中，主要展示某公司的产品累计趋势，产品新增趋势，销售柱状图，地图等内容，包括数字，图表等方式，具体如下所示：
页面设计
为了数据展示，将数字化大屏页面分为8个部分（标题，时间，左1，左2，中1，中2，右1，右2）如下所示：
页面布局核心代码，如下所示：
数字化大屏
某某公司数字化大屏
1123
234
1345
456
累计生产
剩余生产
累计销售
累计返厂
核心代码
后台数据
在本例中，flask做为web开发框架，提供了一个轻量级的实现web服务的功能。另本为了演示，实现了部分功能，其他则为静态数据，如下所示：
from flask import Flask
from flask import request
from flask import render_template
from flask import jsonify
import random
app = Flask(__name__)
@app.route('/main')
def main():
return render_template('main.html')
@app.route('/get_c1_data', methods=['get', 'post'])
def get_c1_data():
"""获取C1数据"""
total_confirmed = random.randint(0, 10000) # 累计生产
remain_suspect = random.randint(0, 5000) # 剩余生产
total_cure = random.randint(0, 10000) # 累计销售
total_dead = random.randint(0, 200) # 累计返厂
return jsonify({"total_confirmed": total_confirmed, "remain_suspect": remain_suspect, "total_cure": total_cure,
"total_dead": total_dead})
if __name__ == '__main__':
app.run()注意：jQuery进行ajax数据访问，返回的json格式的数据，所以引入flask中的jsonify模块，进行数据转换。
ajax访问
在本例中，为了实现局部刷新，采用ajax的方式进行访问，如下所示：
图表展示
在本例中，展示了多种图表，且各自独立，为了方便起见，将各个模块的图表，单独保存在js文件中。
