本文主要讲下pycurl 安装使用.

1.安装

首先使用 pip 命令安装.

pip install pycurl

输出如下:

Collecting pycurl

解决安装失败的步骤如下:

1. sudo apt-get install libcurl4-openssl-dev
2. sudo apt-get install python-dev
3. sudo apt-get install libssl-dev
4. pip install pycurl

此时,可以看到安装成功.

2: 使用

pycurl是一个基于libcurl库的Python模块，它支持多种网络协议的，包括HTTP、HTTPS等。

使用pycurl可以进行网络请求、文件上传、下载等操作。

下面是使用get请求 , 访问百度. 并打印response.

import pycurl
# 创建一个Curl对象
curl = pycurl.Curl()
# 设置请求的URL
ccurlsetopt(curl.URL, 'http://www.baidu.com')
# 设置请求的方法为GET
curl.setopt(curl.HTTPGET, 1)
# 执行请求
curl.perform()

# 获取响应内容
response = curl.getinfo(curl.RESPONSE_CODE)
print(response)

# 关闭Curl对象
curl.close()
