Today, let's take a look at the usage and parameters of Pycurl

Common methods:

Pycurl. Curl () #创建一个pycurl对象的方法

Pycurl. Curl (). setopt (Pycurl. URL, http://www.pythontab.com) #设置要访问的URL

Pycurl. Curl (). setopt (Pycurl. ConnectTimeout, 60)

Pycurl. Curl (). setopt (Pycurl. TIMEOUT, #连接超时设置

Pycurl. Curl (). setopt (Pycurl. UserAgent, "mozilla/5.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1,. NET CLR 1.1.4322) #模拟浏览器

Pycurl. Curl (). Perform () #服务器端返回的信息

Pycurl. Curl (). GetInfo (Pycurl. Http_code) #查看HTTP的状态 similar to the status attribute in Urllib

Pycurl. Namelookup_time Domain Name resolution time

Pycurl. Connect_time Remote Server Connection time

Pycurl. Pretransfer_time the time after the connection is over to the start of the transfer

Pycurl. Starttransfer_time the time that the first byte was received

Pycurl. Total_time the total time of the previous request

Pycurl. Redirect_time If there is a turn, the time spent

A friend familiar with PHP may have discovered that the Curl Library is very similar to PHP's curl.
