Python技術宛若一把神奇的魔杖,它有著強大的功力,可以幫助開發(fā)者們輕松實現一些頂尖級的技術。
其中,“秒殺”技術就是其中一種最具有代表性的例子。而在這個過程中,Python語言的巨大優(yōu)勢得以充分發(fā)揮,從而使這種技術得以更好的實現。
import requests import json import time class Zhihu: def __init__(self, question_url, answer_id, headers): self.question_url = question_url self.answer_id = answer_id self.headers = headers self.request_session = requests.session() self.request_session.headers.update(self.headers) self.question_id = self.__get_question_id() self.question_title = self.__get_question_title() def __get_question_id(self): question_id = self.question_url.split("/")[-1] return question_id def __get_question_title(self): response = self.request_session.get(self.question_url) question_title = response.text.split('')[1].split(" ")[0] return question_title def get_vote_count(self): url = "https://www.zhihu.com/api/v4/answers/{}/voters?include=data[*].is_following&limit=5000&offset=0".format(self.answer_id) response = self.request_session.get(url) vote_count = json.loads(response.text)["paging"]["totals"] return vote_count def vote(self): """點贊""" url = "https://www.zhihu.com/api/v4/answers/{}/voters".format(self.answer_id) response = self.request_session.post(url) status_code = response.status_code return status_code zhihu_headers = { "User-Agent": "", "Cookie": "" } zhihu_question_url = "" zhihu_answer_id = "" zhihu = Zhihu(zhihu_question_url, zhihu_answer_id, zhihu_headers) print(zhihu.question_title) print("答案點贊數為:{}".format(zhihu.get_vote_count())) while True: result = zhihu.vote() if result == 201: print("點贊成功,當前點贊數為:{}".format(zhihu.get_vote_count())) break else: print("點贊失敗,正在重試...") time.sleep(0.1)
上面這段Python代碼就是一個簡單的知乎“秒殺”例子,它可以幫助你自動點贊一個答案,從而提高答案的曝光率。其中,Python的requests和json庫協作,實現了對知乎網站API的請求與解析;同時,Python的time庫也幫助我們實現了一個簡單的“暫停執(zhí)行”功能,從而使代碼更加穩(wěn)定可靠。
可以看到,Python秘笈的奧妙全在于它的多功能性和高效性。應用它,可以實現很多我們想象不到的功能。而這種用Python實現“秒殺”的技巧則體現了這一點。但同時,也要注意遵守法律規(guī)定,不要隨意侵權或者違反知乎的相關規(guī)定。
