随机构建请求头 User-Agent

from fake_useragent import UserAgent
if __name__ == "__main__":
    # 随机生成 useragent
    ua = UserAgent()
    print(ua.ie)
    print(ua.opera)
    print(ua.chrome)
    print(ua.firefox)
    print(ua.safari)
    print("====== 随机 ==========")
    for i in range(10):
        print(ua.random)

结果：
