python爬虫可视化

一、思路分析

本文采用比特币网站作为爬取目标（https://www.ibtctrade.com/），从中获取prices、CNY、市值等，然后导出所得到的数据到excel、sqlite数据中。使用pyarm中的flask框架搭建可视化平台，使用sqlite数据库的数据制作简单的网页，并制作折线图、柱状图、散点图等等。

二、数据爬取

1.引入库

代码如下：

from bs4 import BeautifulSoup
import re
import urllib.error,urllib.request
import xlwt
import sqlite3
1
2
3
4
5

2.获取目标网页

代码如下：

baseURL = 'https://www.ibtctrade.com/cryptocurrency/p_'  #比特币交易网的数据一共有27页，分别在此网址上加上后缀，即可实现每个网页的获取
head = {'user-agent': 'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904.108 Safari/537.36'

    }
    request = urllib.request.Request(url,headers=head)
    html = ""

    response = urllib.request.urlopen(request)
    html = response.read().decode('utf-8')


    # print(html)
    return html

该处使用的url网络请求的数据。

2.解析网页

代码如下：

findjname = re.compile(r'<strong data-v-2dd1dc90="">(.*?)</strong>')
findname = re.compile(r'<span data-v-2dd1dc90="">(.*?)</span>')
findnewprice = re.compile(r'<li data-v-2dd1dc90="">\n(.*?)</li>',re.S)
findtwofourzhangdie = re.compile(r'<li class=".*" data-v-2dd1dc90="">(.*?)</li>',re.S)
# findtwofourdie = re.compile(r'<li class="down" data-v-2dd1dc90="">(.*?)</li>',re.S)
findcny = re.compile(r'<li data-v-2dd1dc90="">\n(.*?)</li>',re.S)
findshizhi = re.compile(r'<li data-v-2dd1dc90="">\n(.*?)</li>',re.S)
    

def getdata(baseURL):
    datalist = []
    for i in range(1,28):
        url = baseURL + str(i)+'.html'
        html = askurl(url)

        soup = BeautifulSoup(html,'html.parser')
        for item in soup.select('.content>a'):
            data =[]
            # print(item)
            item = str(item)
            jname = re.findall(findjname,item)[0]


            data.append(jname)

            name = re.findall(findname,item)[0]

            data.append(name)
            # print(data)

            newprice = re.findall(findnewprice,item)[0]


            data.append(newprice.strip())
            twofourzhangdie = re.findall(findtwofourzhangdie,item)[0]



            data.append(twofourzhangdie.strip())
            cny = re.findall(findcny,item)[1]
            data.append(cny.strip())
            shizhi = re.findall(findshizhi,item)[2]
            data.append(shizhi.strip())

            datalist.append(data)

    #　print(datalist)
    return datalist

    # print(html)
    return html

使用正则表达式进行数据的筛选和清洗

3.数据保存到excel

代码如下：

path = "比特币简易数据.xls"
dbpath = "比特币.db"
    # askurl(baseURL)
def savedata(datalist,path):
    print('正在saving·······')
    book = xlwt.Workbook(encoding='utf-8',style_compression=0)
    sheet = book.add_sheet('比特币数据',cell_overwrite_ok=True)
    col = ('简称','全称','最新价格','24H涨跌幅','24H成交额','市值')
    for i in range(0,6):
        sheet.write(0,i,col[i])
    for i in range(0,700):
        data = datalist[i]
        for j in range(0,6):
            sheet.write(i+1,j,data[j])
    book.save(path)

代码如下：

path = "比特币简易数据.xls"
dbpath = "比特币.db"
    # askurl(baseURL)
ef savedb(datalist,dbpath):
    init_db(dbpath)
    conn = sqlite3.connect(dbpath)
    cur = conn.cursor()
    for data in datalist:
        for i in range(len(data)):
            data[i] = '"' +data[i]+'"'
            sql = """
                insert into bitebi750
                (jname, name,newprice,twofourzhangdie,cny,shizhi)
                values(%s)"""%','.join(data)
        cur.execute(sql)
        conn.commit()
    cur.close()
    conn.close()




def init_db(dbpath):
    sql = '''

            (id integer primary key autoincrement,
                jname text,

                twofourzhangdie text,
                cny text,

    conn =sqlite3.connect(dbpath)
    cursor =conn.cursor()
    cursor.execute(sql)

三、基于flask框架的可视化

app.py

提示：这里对文章进行总结：
在app.py中对sqlite数据库的数据进行提取处理，主要把参数，传给所需要的数据，来制作图表，每个html的代码过多，不在贴出，可根据index.html自行修改.

from flask import Flask,render_template
import sqlite3
app = Flask(__name__)


@app.route('/')
def index():
    return render_template('index.html')
@app.route('/shuju')
def e():
    datalist = []
    con = sqlite3.connect("比特币.db")
    cur = con.cursor()
    sql = "select*from bitebi750"
    data = cur.execute(sql)
    for item in data:
        datalist.append(item)
    cur.close()
    con.close()
    return render_template('shuju.html',movies = datalist)

@app.route('/zhangdie')
def zhangdie():
    num = []
    sum = []
    con = sqlite3.connect("比特币.db")
    cur = con.cursor()
    sql = "select jname,twofourzhangdie from bitebi750 limit 0,70"
    data = cur.execute(sql)
    for item in data:
        num.append(str(item[0]))
        sum.append(float(item[1][:-1]))
    cur.close()
    con.close()
    return render_template("zhangdie.html",num = num ,sum = sum)
@app.route('/wordcloud')
def wordcloud():
    return render_template('wordcloud.html')


@app.route('/qujian')
def qujian():
    num = []
    sum = []
    con = sqlite3.connect("比特币.db")
    cur = con.cursor()
    sql = "select jname,newprice from bitebi750 limit 0,15"
    data = cur.execute(sql)
    for item in data:
        num.append(str(item[0]))
        sum.append(float(item[1][1:]))
    cur.close()
    con.close()

    return render_template('qujian.html',num = num ,sum = sum)

@app.route('/sandian')
def sandian():
    num = []
    sum = []
    yum = []
    con = sqlite3.connect("比特币.db")
    cur = con.cursor()

    data = cur.execute(sql)
    for item in data:

        sum.append(float(item[1][:-1]))
        yum.append(float(item[2][1:-1]))
    cur.close()
    con.close()
    return render_template('sandian.html',num = num ,sum = sum ,yum =yum)
@app.route('/shuliang')
def shuliang():
    q = 0
    w = 0
    e = 0
    r = 0
    t = 0
    y = 0
    u = 0

    sum = []
    con = sqlite3.connect("比特币.db")
    cur = con.cursor()
    sql = "select jname,shizhi from bitebi750 limit 0,204"
    data = cur.execute(sql)
    for item in data:

        sum.append(float(item[1][1:-1]))
    for i in sum:
        if i>500 and i<1000:
            q += 1
        elif i>100 and i<500:
            w+=1
        elif i>1 and i<100:
            e+=1
    sql = "select jname,shizhi from bitebi750 limit 204,700"
    data = cur.execute(sql)
    for item in data:

        sum.append(float(item[1][1:-1]))
        for i in sum:
            if i>100 and i<=1000:
                r+=1
            elif i>1000 and i<9999:
                y+=1
            elif i > 1 and i < 10:
                t+=1
            elif i > 10 and i < 100:
                u+=1


    cur.close()
    con.close()
    return render_template("shuliang.html",q=q,w=w,e=e,r=r,t=t,y=y,u=u)
if __name__ == '__main__':
    app.run()
