問題描述

python中的requests如何中斷請(qǐng)求呢？ 我是多線程并發(fā)去get，但是沒找到停止請(qǐng)求操作，只能wait線程結(jié)束，我以前用過socket套接字，里面寫個(gè)狀態(tài)停止read那種就可以。 requests沒找到類似的方法。

import requestsfrom threading import Threadfrom contextlib import closingimport jsonimport timeclass TestT(Thread): def __init__(self):super(TestT, self).__init__()self.s = requests.session() def stop(self):self.p.connection.close()self.s.close() def run(self):t = time.time()self.p = self.s.get(’http://api2.qingmo.com/api/column/tree/one?Pid=8&Child=1’, stream=True, timeout=10)# 消耗了很多時(shí)間print time.time()-twith closing(self.p) as r: print time.time()-t data = ’’ for chunk in r.iter_content(4096):data += chunk print json.loads(data)print time.time()-tt = TestT()t.start()t.join(30)t.stop()t.join()

改了下，用了流式讀取，但是 get的時(shí)候，還是花了3秒多，如何中斷這3秒？

問題解答

加一個(gè)IsStop變量，然后return停止線程

import requestsfrom threading import Threadfrom contextlib import closingimport jsonimport timeclass TestT(Thread): def __init__(self):super(TestT, self).__init__()self.s = requests.session()self.IsStop = False def stop(self):self.p.connection.close()self.s.close()self.IsStop = True def run(self):t = time.time()self.p = self.s.get(’http://api2.qingmo.com/api/column/tree/one?Pid=8&Child=1’, stream=True, timeout=10)# 消耗了很多時(shí)間print time.time()-twith closing(self.p) as r: print time.time()-t data = ’’ for chunk in r.iter_content(4096):if self.IsStop : return Nonedata += chunk print json.loads(data)print time.time()-tt = TestT()t.start()t.join(30)t.stop()t.join()
