python 爬百度热搜并生成词云_搜索内容 词云

 1、爬取百度body存入txt

def get_baidu_hot():
   url = "https://top.baidu.com/board?tab=realtime"
   headers = {
       "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3"}
   response = requests.get(url, headers=headers)
   response.encoding = "utf-8"
   soup = BeautifulSoup(response.text, "html.parser")
   txt=soup.find_all("body")
   print(txt)
   my_utils.write_file(txt)
'
运行
运行

 2、读取txt正则匹配获取json

data=my_utils.read_file()

 3、将json存入数据库

json2=my_utils.ana_baidu(data)

# 假设表名为 "users"
    table_name = "users"
    # 遍历 JSON 数据中的键值对，生成插入语句
    insert_statements = []
    for i in json2:
        str=f"INSERT INTO {table_name} ("
        for key, value in i.items():
            str= str+f"`{key}`, "
        print(str)
        str=str[:-2]+") VALUES ("
        str2=""
        for key, value in i.items():
            str2= str2+f"'{value}', "
        str3=str+str2[:-2]+");"
        print   (str3)
        my_sql.exe_sql(str3)

 4、读取数据库信息生成词云

    result_content=my_sql.query_sql("select `desc` from users order by create_time desc limit 50")
    result_content=str(result_content)
    result_content=result_content.replace("的","")
    my_wcloud.create_cy(result_content)
