爬取代理IP
阿新 • • 發佈：2018-12-09
現在爬蟲好難做啊，有些網站直接封IP，本人小白一個，還沒錢，只能找免費的代理IP，於是去爬了西刺免費代理，結果技術值太低，程式還沒除錯好，
IP又被封了。。。
IP又被封了。。。
IP又被封了。。。
於是又開始找其他的免費代理，找到了89免費代理，這個網站提供了API介面。在我除錯過程中發現，這個API介面好像對爬蟲沒啥限制，哈哈哈！！！
下面附上程式碼：
1.這次找了好多User-Agent，以防萬一。

2.傳送請求，通過正則表示式獲取IP列表
def get_ip_list(self,url):
header = random.choice(self.headers)
response = requests.get(url,headers=header)
ip_list = re.findall(r"(.*?)<br>", response.content.decode())[1:]
for ip in ip_list:
self.get_ip_queue.put(ip)3.檢查代理IP是否可用
def check_ip(self): while not self.get_ip_queue.empty(): ip = self.get_ip_queue.get() proxy = {"http": "http://" + ip, "https": "https://" + ip} header = random.choice(self.headers) try: response = requests.get(self.check_ip_url,headers=header,proxies=proxy,timeout=3) except: print(ip,"連線超時") else: print(ip,response.status_code) if response.status_code == 200: self.pass_ip_list.append(ip) self.get_ip_queue.task_done()
4.儲存到csv檔案中
def save_csv(self,pass_ip_list):
pass_ip_df = pd.DataFrame({"ip": pass_ip_list})
pass_ip_df.to_csv("./ip.csv", index=False)5.主執行程式
def run(self):
"""執行程式"""
t_start = datetime.datetime.now()
# 1.獲取代理IP列表
self.get_ip_list(self.get_ip_url)
# 2.驗證代理IP有效性
for i in range(100):
t = threading.Thread(target=self.check_ip)
t.setDaemon(True)
t.start()
self.get_ip_queue.join()
# 3.儲存代理IP至csv檔案
print("*" * 100)
self.save_csv(self.pass_ip_list)
t_end = datetime.datetime.now()
print("儲存成功", t_end.strftime('%Y-%m-%d %H:%M:%S'))
print("用時{}".format(t_end-t_start),"獲取{}個代理IP".format(len(self.pass_ip_list)))

人生苦短，還是要積極地走下去！
