1.requests的高級(jí)應(yīng)用 ~ 會(huì)話維持

# 利用Session對(duì)象發(fā)送get請(qǐng)求:from requests import Sessionsession = Session()res = session.get(url=url, headers=headers)# 利用Session對(duì)象發(fā)送post請(qǐng)求:from requests import Sessionsession = Session()data = {"username": "Jeremy","pwd": "123456"}res = session.get(url=url, data=data, headers=headers)

模擬登陸快代理

from requests import Session # 1.實(shí)例化session對(duì)象 session = Session() url = "https://www.kuaidaili.com/login/" data = {... } # 2.發(fā)送post請(qǐng)求 res_login = session.post(...) # 3.訪問(wèn)跟人中心頁(yè)面 res_index = session.get(...) # 4.寫入文件看效果 with open('index.html', 'w', encoding="utf-8") as f:f.write(res_index.text)

2.打碼平臺(tái)

#使用流程:

• 注冊(cè)賬號(hào):
  普通賬戶: 充錢的
  開(kāi)發(fā)賬戶: 調(diào)接口進(jìn)行打碼
• 登陸普通用戶: 查詢剩余積分, 在線充值
• 開(kāi)發(fā)者登陸:
  我的軟件–>創(chuàng)建新軟件: 名字隨便, 秘鑰不要改—>軟件代碼 + 通訊秘鑰
  開(kāi)發(fā)文檔:PythonHTTP操作示例

3.云打碼平臺(tái)接口使用
