GitHub爬虫项目详解：构建大规模账号池与本地部署实践

账号池搭建

必要性

常见登录方式：

基于Session + Cookie的登录

基于JWT的登录：登录生成JWT字符串

账号池存储cookie或者JWT字符串方便后续发请求爬取数据

本地部署

conda建立一个虚拟环境

conda create -n new_env python=3.x  # 替换 x 为你需要的 Python 版本

激活新建环境
```
conda activate new_env
```
安装依赖项
```
pip install -r requirments.txt
```
修改setting.py配置文件
配置redis数据库

  # redis host
  REDIS_HOST = env.str('REDIS_HOST', '127.0.0.1')
  # redis port
  REDIS_PORT = env.int('REDIS_PORT', 6379)
  # redis password, if no password, set it to None
  REDIS_PASSWORD = env.str('REDIS_PASSWORD', None)
  # redis db, if no choice, set it to 0
  REDIS_DB = env.int('REDIS_DB', 0)

配置检测网址

  GENERATOR_MAP = {
      'antispider6': 'Antispider6Generator',
      'antispider7': 'Antispider7Generator'
  }
  
  # integrated tester
  TESTER_MAP = {
      'antispider6': 'Antispider6Tester',
      'antispider7': 'Antispider7Tester',
  }
  
  TEST_URL_MAP = {
      'antispider6': 'https://antispider6.scrape.center/',
      'antispider7': 'https://antispider7.scrape.center/'
  }

配置生成网址

      def generate(self, username, password):
          """
          generate main process
          """
          if self.credential_operator.get(username):
              logger.debug(f'credential of {username} exists, skip')
              return
          login_url = 'https://antispider7.scrape.center/api/login'
          s = requests.Session()
          r = s.post(login_url, json={
              'username': username,
              'password': password
          })
          if r.status_code != 200:
              logger.error(f'error occurred while generating credential of {username}, error code {r.status_code}')
              return
          token = r.json().get('token')
          logger.debug(f'get credential {token}')
          self.credential_operator.set(username, token)

配置账号密码的生成机制

可以利用虚拟号接受验证码注册账号密码，需要花钱但不贵

def init(self):
    """
        do init
        """
    for i in range(1, self.MAX_COUNT + 1):
        self.account_operator.set(f'admin{i}', f'admin{i}')
