fake_useragent

fake_useragent第三方庫，來實現隨機請求頭的設置

安裝

pip3 install fake-useragent

用法

from fake_useragent import UserAgent
ua = UserAgent()
print(ua.ie)
print(ua.opera)
print(ua.chrome)
print(ua.firefox)
print(ua.safari)
print(ua.random)    獲取任意請求頭

報錯：

fake_useragent.errors.FakeUserAgentError: Maximum amount of retries reached

解決

• 禁用服務器緩存

ua = UserAgent(use_cache_server=False)

• 忽略ssl驗證

ua = UserAgent(verify_ssl=False)

• 使用json文件

1、wget https://fake-useragent.herokuapp.com/browsers/0.1.11
2、mv 0.1.11 fake_useragent_0.1.11.json

ua = UserAgent(path="./fake_useragent_0.1.11.json")  #path后面跟下載的json文件路徑

例

#! /usr/bin/python3
# -*- congfig:utf-8 -*-

from fake_useragent import UserAgent

def test():
    ua = UserAgent()
    ua = UserAgent(path="./fake_useragent_0.1.11.json")
    return ua.random
if __name__ == "__main__":
    for i in range(5):
        print(test())
