Alf*_*ang 5 python asynchronous http python-3.x
有没有办法像node.js一样让python3异步?
我想要一个最小的例子,我已经尝试了下面的方法,但仍然适用于同步模式。
import urllib.request
class MyHandler(urllib.request.HTTPHandler):
@staticmethod
def http_response(request, response):
print(response.code)
return response
opener = urllib.request.build_opener(MyHandler())
try:
opener.open('http://www.google.com/')
print('exit')
except Exception as e:
print(e)

如果异步模式有效,则应print('exit')首先显示 。
有人可以帮忙吗?
使用线程(基于您自己的代码):
import urllib.request
import threading
class MyHandler(urllib.request.HTTPHandler):
@staticmethod
def http_response(request, response):
print(response.code)
return response
opener = urllib.request.build_opener(MyHandler())
try:
thread = threading.Thread(target=opener.open, args=('http://www.google.com',))
thread.start() #begin thread execution
print('exit')
# other program actions
thread.join() #ensure thread in finished before program terminates
except Exception as e:
print(e)
