写在前面，最近收到了很多小伙伴们的建议，大屏得展示数据如果采用真实数据分析计算，那就更加贴近小伙伴们的实际工作场景，可以很快在工作中应用，所以应小伙伴需求，就诞生了这篇数据可视化+爬虫的【bilibili排行榜- 数据可视化大屏解决方案】。
之前小伙伴们建议我出一些视频课程来学习Echarts，这样可以更快上手，所以我就追星赶月的录制了《Echart-0基础入门》系列课程（共14节课），希望小伙伴们多多支持。
话不多说，开始分享干货，欢迎讨论！QQ微信同号： 6550523
❤️效果展示❤️
1、首先看动态效果图
2、丰富的主题样式
一、确定需求方案
1、确定产品上线部署的屏幕LED分辨率
1280px*768px，F11全屏后占满整屏无滚动条；其它分辨率屏幕可自适应显示。
2、部署方式
基于免安装可执行程序：支持Windows、Linux、Mac等各种主流操作系统；将可执行程序exe复制到服务器上即可，无需其它环境依赖；观看方式：既可在服务器上直接观看程序界面，也可远程使用浏览器打开播放，支持Chrome浏览器、360浏览器等主流浏览器。二、整体架构设计
前端基于Echarts开源库设计，使用WebStorm编辑器；后端基于Python Web实现，使用Pycharm编辑器；数据传输格式：JSON；数据源类型：本案例采用python request 采集实时数据方式。实际开发需求中，支持定制HTTP API接口方式或其它各种类型数据库，如PostgreSQL、MySQL、Oracle、Microsoft SQL Server、SQLite、Excel表格等。数据更新方式：本案例为了展示数据，采用定时拉取方式。实际开发需求中，采用后端数据实时更新，实时推送到前端展示；三、爬虫采集关键编码实现
1、确定爬虫目标网址
本次采集的目标是bilibili实时热点数据，url地址为：哔哩哔哩排行榜bilibili是国内知名的视频弹幕网站，这里有最及时的动漫新番，最棒的ACG氛围，最有创意的Up主。大家可以在这里找到许多欢乐。/v/popular/rank/ent调用的api地址为：/x/web-interface/ranking/v2?type=all
2、爬取关键代码
def scrapy(url):headers = {"Content-Type": 'application/json;charset=utf-8',# "cookie": cookie,"User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/94.0.4606.81 Safari/537.36"}result_obj = {}try:response = requests.get(url=url, headers=headers, verify=False)result_obj = json.loads(response.text)except Exception as e:print(e)if 0 == result_obj['code']:return result_obj["data"]["list"]else:result_obj['code'] = 'error'return result_obj
四、数据可视化关键编码实现
1、前端html代码
<div class="container_fluid"><div class="row_fluid" id="vue_app"><div style="padding:0px; height:10%; " class="col-xs-12 col-md-12"><dv-decoration-4 :reverse="true" style="height:20%;"></dv-decoration-4><h3 style="color:#cba871;text-align:center;height:80%;" id="container_h">container_h</h3></div><div style="padding: 0px;" class="col-xs-12 col-md-4"><div style="padding: 0px; height:60%;" class="col-xs-12 col-md-12"><dv-border-box-2 style="padding: 12px; " :color="['#cba871', '#25201f']"><h6 style=" color:#cba871; text-align: center; "> - bilibli视频播放（iframe方式） - </h6><div style="padding:5%; height:90%; " id="container_2"><iframesrc="///player.html?aid=891284092&bvid=BV1eP4y1b7Pt&cid=432844457&page=1"scrolling="no" border="0" frameborder="no" framespacing="0" allowfullscreen="true"width="100%" height="100%"> </iframe></div></dv-border-box-2></div></div><div style="padding:0px;" class="col-xs-12 col-md-4"><div style="padding:0px; height:60%;" class="col-xs-12 col-md-12"><dv-border-box-2 style="padding: 12px; " :color="['#cba871', '#25201f']"><h6 style=" color:#cba871; text-align: center;"> - 地区分布 - </h6><div style="padding:5%; height:90%;" id="container_3">container_3</div></dv-border-box-2></div></div><div style="padding: 0px;" class="col-xs-12 col-md-4"><div style="padding: 0px; height:30%;" class="col-xs-12 col-md-12"><dv-border-box-2 style="padding: 12px; " :color="['#cba871', '#25201f']"><h6 style=" color:#cba871; text-align: center; height:3%;"> - 用户年龄&性别分布 - </h6><div style="padding: 0px; " class="col-xs-12 col-md-6"><div style="padding:5%; height:90%;" id="container_4_1">container_4_1</div></div><div style="padding: 0px; " class="col-xs-12 col-md-1"><div style="width: 0.3px; align:center; height: 80%; background: #cba871;"></div></div><div style="padding: 0px; " class="col-xs-12 col-md-5"><div style="padding:5%; height:90%;" id="container_4_2">container_4_2</div></div></dv-border-box-2></div><div style="padding: 0px; height:30%;" class="col-xs-12 col-md-12"><dv-border-box-2 style="padding: 12px; " :color="['#cba871', '#25201f']"><h6 style=" color:#cba871; text-align: center;height:3%;"> - 访问来源&会员等级 - </h6><div style="padding: 0px; " class="col-xs-12 col-md-6"><div style="padding:5%; height:90%;" id="container_5_1">container_5_1</div></div><div style="padding: 0px; " class="col-xs-12 col-md-1"><div style="width: 0.3px; align: center; height: 80%; background: #cba871;"></div></div><div style="padding: 0px; " class="col-xs-12 col-md-5"><div style="padding:5%; height:90%;" id="container_5_2">container_5_2</div></div></dv-border-box-2></div></div><div style="padding:0px;" class="col-xs-12 col-md-12"><div style="padding:0px; height:30%;" class="col-xs-12 col-md-12"><dv-border-box-2 style="padding: 12px; " :color="['#cba871', '#25201f']"><h6 style="color:#cba871; text-align: center; "> - 全站热榜排行(python爬取bilibli) - </h6><div style=" padding:1%; height:90%; " id="container_6">container_6</div></dv-border-box-2></div></div></div></div>
2、前端JS代码
var idContainer_6 = "container_6";var chartDom = document.getElementById(idContainer_6);var myChart = echarts.init(chartDom, window.gTheme);var option;option = {grid: {left: "1%",right: "1%",bottom: "15%",top: "1%",containLabel: true,},tooltip: {trigger: "axis",axisPointer: {type: "none",},formatter: function (params) {return params[0].name + ": " + params[0].value;},},dataZoom: [{type: "slider",xAxisIndex: 0,start: 0,end: 20,bottom: "-5%"},],xAxis: {data: [],axisTick: { show: false },axisLine: { show: false },axisLabel: {color: "rgba(255,255,255,.8)",},},yAxis: {splitLine: { show: false },axisTick: { show: false },axisLine: { show: false },axisLabel: { show: false },},// color: ["#cba871"],series: [{type: "pictorialBar",barCategoryGap: "-100%",label: {normal: {show: true,position: "top",textStyle: {color: ["#cba871"],},},},symbol: "path://M0,10 L10,10 C5.5,10 5.5,5 5,0 C4.5,5 4.5,10 0,10 z",itemStyle: {opacity: 1,},emphasis: {itemStyle: {opacity: 1,},},data: [],z: 10,},],};function asyncData_6() {$.getJSON("json/6.json").done(function (data) {var myChart = echarts.init(document.getElementById(idContainer_6));myChart.setOption(data);}); //end $.getJSON}window.addEventListener("resize", function () {myChart.resize();});myChart.setOption(option);asyncData_6();
3、后端python服务器代码
# -*- coding:utf-8 -*-import jsonimport scrapyBilibili as scrapyBilibilifrom http.server import HTTPServer, SimpleHTTPRequestHandler, ThreadingHTTPServerip = "localhost" # 监听IP，配置项port = 8819 # 监听端口，配置项class MyRequestHandler(SimpleHTTPRequestHandler):protocol_version = "HTTP/1.0"server_version = "PSHS/0.1"sys_version = "Python/3.7.x"target = "./" # 监听目录，配置项def do_GET(self):url = ""data = []# 处理客户端的动态请求if self.path.find("/json/6.json") >= 0:data = scrapyBilibili.filter(scrapyBilibili.scrapy("/x/web-interface/ranking/v2?type=all"))else:SimpleHTTPRequestHandler.do_GET(self)return# 响应http headerself.send_response(200)self.send_header("Content-type", "json")self.end_headers()# 响应http responserspstr = json.dumps(data)self.wfile.write(rspstr.encode("utf-8"))# def do_GET(self):#if self.path.find("/json/") > 0:# print(self.path)# req = {"success": "true"}# self.send_response(200)# self.send_header("Content-type", "json")# self.end_headers()# with open(self.path, 'r', encoding="utf-8") as f:# data = json.load(f)# rspstr = json.dumps(data)# self.wfile.write(rspstr.encode("utf-8"))#else:# SimpleHTTPRequestHandler.do_GET(self);def do_POST(self):data = self.rfile.read(int(self.headers["content-length"]))data = json.loads(data)self.send_response(200)self.send_header("Content-type", "text/html")self.end_headers()rspstr = json.dumps(data, ensure_ascii=False)self.wfile.write(rspstr.encode("utf-8"))def HttpServer():try:server = HTTPServer((ip, port), MyRequestHandler)listen = "http://%s:%d" % (ip, port)print("服务器监听地址： ", listen)server.serve_forever()except Exception as e:print("Exception", e)server.socket.close()if __name__ == "__main__":HttpServer()
