使用 Python 请求测量网站加载时间 [英] Measure website load time with Python requests

问题描述

我正在尝试构建一个工具来测试我的互联网连接延迟，更具体地说是网站加载时间.我想使用 python requests 模块来加载部分.

I'm trying to build a tool for testing the delay of my internet connection, more specifically web site load times. I thought of using the python requests module for the loading part.

问题是，它没有内置功能来测量获得完整响应所需的时间.为此，我想我会使用 timeit 模块.

Problem is, it's got no built-in functionality to measure the time it took to get the full response. For this I thought I would use the timeit module.

我不确定的是，如果我像这样运行 timeit:

What I'm not sure about is that if I run timeit like so:

t = timeit.Timer("requests.get('http://www.google.com')", "import requests")

我是真的在测量响应到达所用的时间，还是请求构建、发送、接收等所用的时间?我猜我可能会忽略执行时间，因为我正在测试具有很长延迟(约 700 毫秒)的网络?

I'm I really measuring the time it took the response to arrive or is it the time it takes for the request to be built, sent, received, etc? I'm guessing I could maybe disregard that excecution time since I'm testing networks with very long delays (~700ms)?

有没有更好的方法以编程方式执行此操作?

Is there a better way to do this programatically?

推荐答案

至于你的问题，应该是总时间

As for your question, it should be the total time for

1. 创建请求对象的时间
2. 发送请求
3. 接收回复
4. 解析响应(参见 Thomas Orozco 的评论)

测量单个请求加载时间的其他方法是使用 urllib:

Other ways to measure a single request load time is to use urllib:

nf = urllib.urlopen(url)
start = time.time()
page = nf.read()
end = time.time()
nf.close()
# end - start gives you the page load time
