在python中进行线程编程 [英] threading programming in python
问题描述
有一个实现注册的功能。代码如下:
$ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $
...
如果为真:
sendmail()
返回重定向(url_for('onepage'))
我的问题是:
当执行sendmail()时,需要很多时间。所以用户不得不等待片刻,大约4-5秒。这会带来不好的体验。我知道使用线程可以让这两个函数相互独立,但是我已经学习了很短的时间编程,所以我没有线程编程方面的经验,有没有人可以提供一些想法或代码示例来解决这个问题?
你想要的是 线程
而不是低级别 thread
。对于这种简单的情况,不需要继承 threading.Thread
,所以你可以重写 sendmail()
by
threading.Thread(target = sendmail).start()
导入线程
Recently I've been practicing to build a website with flask. Now i encounter a problem.
There is a function which to achieve registration. The code like this:
def register(): ... some judgment ... if true: sendmail() return redirect(url_for('onepage'))
My question is :
When preforming sendmail(), it needs much time. So the users have to wait for a moment to get "onepage", about 4-5s. This will bring a bad experience. I know that using threading can let these two functions independently of each other, but I have learnt programming for a very short time so I have no experience in threading programming, Could anybody provide some ideas or code examples for me at this problem?
What you want is threading
rather than the low-level thread
. For a case this simple, there will be no need of subclassing threading.Thread
, so you could just replase sendmail()
by
threading.Thread(target=sendmail).start()
after an
import threading
