超时可以轻松添加到您请求的URL中。碰巧的是,您正在使用第三方URL并等待响应。在URL上设置超时总是一个好习惯,因为我们可能希望URL在一个响应或错误的时间范围内响应。否则,可能会导致无限期地等待该请求。
我们可以通过使用超时参数来给URL超时,并以秒为单位传递值,如下面的示例所示-
import requests
getdata =
requests.get('https://jsonplaceholder.typicode.com/users',timeout=0.001)
print(getdata.text)
raise ConnectTimeout(e, request=request)
requests.exceptions.ConnectTimeout:
HTTPSConnectionPool(host='jsonplaceholder.typicode.com',
port=443): Max retries exceeded with url: /users (Caused
by Connect
TimeoutError(, 'Connection to jsonplaceholder.typicode.com timed out. (connect
timeout = 0.001)'))
给定的超时如下-
getdata =
requests.get('https://jsonplaceholder.typicode.com/users',timeout=0.001)
执行将引发连接超时错误,如输出所示。给定的超时值为0.001,这对于请求取回响应并引发错误是不可能的。现在,我们将增加超时并检查。
import requests
getdata =
requests.get('https://jsonplaceholder.typicode.com/users',timeout=1.000)
print(getdata.text)
E:\prequests>python makeRequest.py

如果超时时间为1秒,我们可以获取所请求URL的响应。
