1，获取数据
如李子染，搜索热度，什么时候开始关注
代码
import requests
import os
import csv
fp = open('data.csv','a+',newline='',encoding='utf-8')
writer = csv.writer(fp)
writer.writerow(['time'])
url_1 = 'https://m.weibo.cn/api/container/getIndex'
headers = {
'Accept':'application/json,text/plain,*/*',
'Mweibo-Pwa':'1',
'referer': 'https://m.weibo.cn/search?containerid=100103type%3D1%26q%3D%E8%8B%B1%E5%9B%BD%E7%95%99%E5%AD%A6&sudaref=m.weibo.cn&display=0&retcode=6102&page_type=searchall',
'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/76.0.3809.100 Safari/537.36'
for i in range(5,55):
url_2={
'containerid':'100103type=1&q=李子染',
"sudaref":"m.weibo.cn",
"display":"0",
"retcode":"6102",
"page_type":"searchall",
"page":str(i)
web=requests.get(url_1,params=url_2)
web_json=web.json()
content=web_json["data"]["cards"]
for item in content:
time=item["mblog"]["created_at"]
print(time)
writer.writerow([time])
2，存入csv
3，对数据的分析和统计
import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
df=pd.read_csv("data.csv",encoding="gbk")
#print(df[u"time"])[:0]
counts=df[u"time"].value_counts()
counts=df[u"time"].value_counts(normalize=True)

6，利用画图库，制作折线图和柱状图
7，分析
李子染，在12-10和12-6搜索达到高峰，整个12月开始都是活跃，从11月开始，这与流量推送和媒体大肆爆光相关。
