HTTP requests.post 超时 [英] HTTP requests.post timeout

问题描述

在我下面的代码中，我使用了 requests.post.如果网站宕机，有哪些可能只是继续?

我有以下代码:

def post_test():进口请求url = 'http://example.com:8000/submit'有效载荷 = {'data1': 1, 'data2': 2}尝试:r = requests.post(url, data=payload)除了:return # 如果 requests.post 失败(例如站点关闭)我只想从 post_test() 返回.目前它挂在 requests.post 中而没有引发错误.如果(r.text == '停止'):sys.exit() # 我想终止整个程序 if r.text = 'stop' - 这很好用.

如果 example.com 或其/submit 应用程序关闭，我如何使 requests.post 超时，或从 post_test() 返回?

解决方案

使用 timeout 参数:

r = requests.post(url, data=payload, timeout=1.5)

注意:timeout不是对整个响应下载的时间限制；相反，如果服务器没有发出响应，则会引发异常timeout 秒(更准确地说，如果在timeout 秒的底层套接字).如果没有指定超时时间明确地，请求不会超时.

In my code below, I use requests.post. What are the possibilities to simply continue if the site is down?

I have the following code:

def post_test():

    import requests

    url = 'http://example.com:8000/submit'
    payload = {'data1': 1, 'data2': 2}
    try:
        r = requests.post(url, data=payload)
    except:
        return   # if the requests.post fails (eg. the site is down) I want simly to return from the post_test(). Currenly it hangs up in the requests.post without raising an error.
    if (r.text == 'stop'):
        sys.exit()  # I want to terminate the whole program if r.text = 'stop' - this works fine.

How could I make the requests.post timeout, or return from post_test() if example.com, or its /submit app is down?

解决方案

Use the timeout parameter:

r = requests.post(url, data=payload, timeout=1.5)

Note: timeout is not a time limit on the entire response download; rather, an exception is raised if the server has not issued a response for timeout seconds (more precisely, if no bytes have been received on the underlying socket for timeout seconds). If no timeout is specified explicitly, requests do not time out.
