第三方库 requests, fake_useragent

代码语言：javascript复制
import random, requests, re, logging, time
from fake_useragent import UserAgent

日志

代码语言：javascript复制
logging.basicConfig(level=logging.INFO , format='%(asctime)s[%(levelname)s]: %(message)s')
logger = logging.getLogger(__name__)

随机获取请求头User-Agent

代码语言：javascript复制
def getHeader():
    return {'Referer': 'https://blog.csdn.net','User-Agent': UserAgent().random}

解析读取量

代码语言：javascript复制
def parse_html(text:str):
    return int(re.search(r'<span class="read-count">([0-9]*)</span>', text).group(1))

请求网页

代码语言：javascript复制
def requestUrlText(url):
    try:
        header = getHeader()
        response = requests.get(url, headers=header)
        if response.status_code == 200:
            return parse_html(response.text)
    except (requests.RequestException, AttributeError):
        return False

封装为请求url类

代码语言：javascript复制
class request_url():
    def __init__(self, url:str):
        self.url = url
        self.read = 0
    def succeeded(self): #弃用
        logging.debug(f"Request Url{self.url} successfully.")

    def _update(self):
        _res = requestUrlText(self.url)
        if isinstance(_res, int):
            self.succeeded()
            _var = _res - self.read
            self.read = _res
            return _var
        return 0
    def update(self):
        while True:
            r = self._update()
            if r: return r
    def readnum(self) -> int:
        return self.read

封装总调用类

代码语言：javascript复制
class request_urls():
    def __init__(self, *args):
        self.__urls = []
        self.add(*args)
        self.all_add = 0
    def add(self, *urls):
        for url in urls:
            self.__urls.append(request_url(url))

    def get(self) -> int:
        return sum([u.update() for u in self.__urls])
    def total(self) -> int:
        return sum([u.readnum() for u in self.__urls])
    def update(self) -> None:
        add = self.get()
        self.all_add  = add
        logger.info(f"total {self.total()}({len(self.__urls)}blogs), ↑{add} [ALL {self.all_add}]")

运行与主程序

代码语言：javascript复制
def run(urls):
    req = request_urls(*urls)
    req.get() #初始化.
    while True:
        req.update()
        time.sleep(random.randint(60, 70))

if __name__ == '__main__':

什么？ 刷取csdn阅读量？那是不可能 csdn主要靠这几种方式获取你是否在requests

项目

Value

1

时间戳 time.time() 时间计算是一个重要方式 如果你再过少时间内请求多次，则视为增加一次阅读量

2

请求头 header 这是大多数网站返回结果考虑的因素

3

Referer 你从哪里来？

4

Cookie IP 单个IP或者是cookie文件 请求次数过多，也会减少阅读量,但其实这一步可以用代理IP 但效果不怎么样

5

用户信息 如(4), 单个用户只能点赞收藏一次

阅读量并不能代表什么 点赞等，综合指标才能上去所以有时间还是要想想发布一些优质的博文.

tcp/ip 网络安全
