1.微博登录

2.爬取数据

3.mysql存储

4.pyechart本地展示

5.用vue搭建网站web展示

先放图：

1.微博登录

新浪微博的登录不是简单的post就能解决的，他的登录有加密，所以我们要使用一定的解密算法才能正常登录微博，得到我们想要的数据。

先不要慌，第一步当然是import我们需要的库

from urllib import request,parse
import http.cookiejar
import base64
import json
import rsa
import binascii
from PIL import Image
from bs4 import BeautifulSoup
import pymysql

要登录，那肯定要先拿到验证码

    def GetCode(self):
        url="https://login.sina.com.cn/cgi/pin.php?r=694905&s=0&p=gz-52086a8a846fadcdacf4fb058324aa387858"#验证码地址
        img=self.opener.open(url)
        f=open('vv.png','wb')
        f.write(img.read())
        f.close()
        im=Image.open('vv.png')
        im.show()

拿到了验证码还不够，登录之前还有个预登录，拿到我们后面加密需要的参数

def prelogin(self):
        url="https://login.sina.com.cn/sso/prelogin.php?entry=weibo&callback=sinaSSOController.preloginCallBack&su=NDc5MTkyNzQyJTQwcXEuY29t&rsakt=mod&checkpin=1&client=ssologin.js(v1.4.19)&_=1529471491358"
        a=self.opener.open(url).read().decode('utf-8')
        a=a[a.find("(")+1:a.find(")")]
        b=json.loads(a)
        return b
‘’‘
sinaSSOController.preloginCallBack({"retcode":0,"servertime":1540617565,"pcid":"gz-65c55b3534f8a1df1330b4708fb6d1b57273","nonce":"ONED4A","pubkey":"EB2A38568661887FA180BDDB5CABD5F21C7BFD59C090CB2D245A87AC253062882729293E5506350508E7F9AA3BB77F4333231490F915F6D63C55FE2F08A49B353F444AD3993CACC02DB784ABBB8E42A9B1BBFFFB38BE18D78E87A0E41B9B8F73A928EE0CCEE1F6739884B9777E4FE9E88A1BBE495927AC4A799B3181D6442443","rsakv":"1330428213","is_openlock":0,"showpin":0,"exectime":10})’‘’

然后用这些参数对登录参数进行加密，说实在话具体的加密细节我也不记得了，当时做的时候拿了个记事本把所有东西记下来然后分析，也查了很多博客的资料才做好。

def GetMixUser(self,username,password):
        username_struct={'username':username}
        rsaPubkey=int(self.pre['pubkey'],16)
        key=rsa.PublicKey(rsaPubkey, 65537)
        message = str(self.pre['servertime']) + '	' + self.pre['nonce'] + '
' + password
        passwd = rsa.encrypt(message.encode('utf-8'), key)
        upass = binascii.b2a_hex(passwd)
        uname=base64.b64encode(parse.urlencode(username_struct).encode('utf-8')).decode('utf-8')[12:]
        mix={'uname':uname,'upass':upass.decode('utf-8')}
        return mix

拿到加密后的登录参数，可以提交了

def login(self,username,password,code):
        mix=self.GetMixUser(username,password)
        uname=mix['uname']
        upass=mix['upass']
        url="https://login.sina.com.cn/sso/login.php?client=ssologin.js(v1.4.19)"
        print("登录中……")
        postData={
            "door":code,
            "encoding":"utf-8",
            "entry":"weibo",
            "from":"null",
            "gateway":1,
            "nonce":self.pre['nonce'],
            "prelt":72,
            "pwencode":"rsa2",
            "qrcode_flag":False,
            "returntype":"META",
            "savestate":7,
            "servertime":self.pre['servertime'],
            "service":"miniblog",
            "rsakv":self.pre['rsakv'],
            "su":uname,
            "sp":upass,
            "url":"https://weibo.com/ajaxlogin.php?framelogin=1&callback=parent.sinaSSOController.feedBackUrlCallBack",
            "useticket":1,
            "vsnf":1
        }
        postData=parse.urlencode(postData).encode('utf-8')
        result=self.opener.open(url,postData).read().decode('gbk')
        url1=result[result.find("replace")+9:result.find(')')-1]
        result=self.opener.open(url1).read().decode("gbk")
        if(result.find("身份")!=-1):
            return False
        result=result[result.find('location')+18:]
        url2=result[:result.find(')')-1]
        self.opener.open(url2).read().decode("gbk")
        return True

2.爬取信息

先得到用户follow的列表

    def GetUserList(self,uid,pageNum):
        url="https://weibo.com/"+str(uid)+"/follow?page="+str(pageNum)
        try:
            result=self.opener.open(url).read().decode('utf-8')
            html = result.replace('\n', '').replace('\t', '').replace('\r', '').replace('\', '')
            html = html[html.find("<!--关注/粉丝列表-->"):html.find("<!--关欧盟隐私协议弹窗-->")]
            soup = BeautifulSoup(html, "html.parser")
            list_a = soup.findAll(name='div', attrs={"class": "info_name W_fb W_f14"})
            name = []
            uid = []
            for a in list_a:
                try:
                    b = a.find(name="a")
                    b = b['usercard']
                    b = b[3:13:]
                    uid.append(b)
                    name.append(a.text)
                    print("加入用户:" + a.text)
                except:
                    print("No Data")
            dic = {"name": name, "uid": uid}
            return dic
        except:
            pass

再拿到这些用户的主页微博言论，我们得到他们发的所有博文

def GetTalks(self,uid):
        rlist = []
        i=0
        html=""
        while(True):
            try:
                result=self.opener.open("https://weibo.com/u/"+str(uid)+"?page="+str(i)).read().decode("utf-8")
                html = result.replace("\t", "").replace("\n", "").replace("\r", "").replace("\", "")
                html = html[html.find("<div class="WB_feed WB_feed_v3 WB_feed_v4""):]
            except:
                pass
            soup=BeautifulSoup(html,"html.parser")
            list_a = soup.find_all(name="div", attrs={"class": "WB_text W_f14"})
            i = i + 1
            if list_a:
                print("第" + str(i) + "页")
                for a in list_a:
                    at=a.text
                    at=at.replace(" ","")
                    if at:
                        rlist.append(at)
                        print("内容存入："+at)
            else:
                break
        return rlist

3.数据存储

我暂时只做了这些，然后存储到数据库吧。mysql的基础语句很简单，我也就会这么几句，不会的百度吧。。

def sqllogin(self):
        db=pymysql.connect(host='localhost',user='root',db='weibouser',passwd='root',charset='utf8mb4')
        return db
    def sqlProcess(self,db):
        while(True):
            cursor=db.cursor()
            cursor.execute("SELECT * FROM USERS WHERE TAG =1")           #1 表示 未处理 2 表示 正在处理 3 表示完成处理
            result=cursor.fetchone()
            if(result):
                cursor.execute("UPDATE USERS SET TAG=2 WHERE USERID='%s'" % (result[2]))
                talks=self.GetTalks(uid=result[2])
                for i in range(1,4):
                   uids=""
                   names=""
                   userlist = self.GetUserList(uid=result[2], pageNum=i)
                   try:
                        uids=userlist['uid']
                        names=userlist['name']
                   except:
                       break
                   if int(result[4])!=3:
                       for t in range(len(uids)):
                           try:
                               if self.IfExist(db,"users","name",names[t])==False:
                                    cursor.execute("INSERT INTO USERS (NAME,USERID,TAG,CLASS) VALUES ('%s','%s',%d,%d)" % (names[t], uids[t], 1, int(result[4])+1))  # 数据库写userlist
                                    cursor.execute("INSERT INTO FOLLOWS (USERID,FUID,FUNAME) VALUES ('%s','%s','%s')" % (result[2], uids[t],names[t]))
                           except:
                               print("Error")
                for talk in talks:
                    try:
                        cursor.execute("INSERT INTO USERTALKS (USERID,NAME,TALK)VALUES ('%s','%s','%s')" % (result[2],result[1],talk))#数据库写评论
                    except:
                        print("Error")
                cursor.execute("UPDATE USERS SET TAG=3 WHERE USERID='%s'"%(result[2]))
            else:
                break
    def AnotherProcess(self,db):
        cursor=db.cursor();
        cursor.execute("SELECT * FROM USERS WHERE 1");
        results=cursor.fetchall()
        for result in results:
            sex="女"
            try:
                r = self.opener.open("https://weibo.com/u/"+result[2]).read().decode("utf-8")
                html = r.replace("\t", "").replace("\n", "").replace("\r", "").replace("\", "")
                if html.find("female") == -1:
                    sex="男"
            except:
                pass
            soup = BeautifulSoup(html, "html.parser")
            keywords=soup.find(attrs={"name":"keywords"})['content']
            description=soup.find(attrs={"name":"description"})['content']
            cursor.execute("INSERT INTO USERDETAILS (NAME,DESCRIPTION,KEYWORDS,SEX)VALUES('{}','{}','{}','{}')".format(result[1],description,keywords,sex))

4.echart本地展示

import pymysql
from pyecharts import Graph
class DrawCharts:
    raw_nodes = []
    links = []
    def __init__(self):
        self.CreatRelation()
        self.DrawCharts()
    def CreatRelation(self):
        db=pymysql.connect(host='localhost',user='root',db='weibouser',passwd='root',charset='utf8mb4')
        cursor=db.cursor()
        cursor.execute("SELECT * FROM USERS WHERE 1");
        users=cursor.fetchall()
        for user in users:#上海大学
            cursor.execute("SELECT * FROM FOLLOWS WHERE USERID='%s'"%(user[2]));
            results=cursor.fetchall()
            if results:
                for result in results:
                    links.append({"source":user[1],"target":result[4]})
                    print(user[1]+"->"+result[4])
        for i in range(3):
            cursor.execute("SELECT * FROM USERS WHERE CLASS=%d"%(i+1))
            results=cursor.fetchall()
            for result in results:
                self.raw_nodes.append({"name": result[1], "symbolSize": 30-i*13,"category":i})


        db.close()
    def DrawCharts(self):
        graph = Graph("微博关注关系图", width=1200, height=600)
        categories=[
            {
            "name":"一级深度",
            "itemStyle":
                {
                    "normal":{
                        "color":'#CC0033',
                        "borderColor": "#5182ab",
                        "borderWidth": 1.8,
                        "show":"True"
                    }
                }
            },
            {
                "name": "二级深度",
                "itemStyle":
                    {
                        "normal": {
                            "color": '#f44242',
                            "borderColor": "#5182ab",

                        }
                    }
            },
            {
                "name": "三级深度",
                "itemStyle":
                    {
                        "normal": {
                            "color": '#663366',
                            "borderColor": "#5182ab",
                            "borderWidth": 1.8,
                            "show":"True"
                        }
                    }
            }
        ]
        graph.add("",self.raw_nodes,self.links,label_pos="right",graph_repulsion=10, is_legend_show=False,categories=categories,
                  label_text_color=None,is_label_show=True)
        graph.render()

效果就不发了，运行起来比较卡，因为节点太多了，当时老师说怎么怎么加速，也不说细节，我当时一脸懵逼，也就没管了，大不了减少节点数量嘛。

5.web展示

前端两段关键代码。。
