python pycurl 安装使用

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 pycurlUsing cached pycurl-7.45.2.tar.gz (234 kB)ERROR: Command errored out with exit status 1:command: /usr/bin/python3 -c 'import sys, setuptools, tokenize; sys.argv[0] = '"'"'/tmp/pip-install-b8co1_ap/pycurl/setup.py'"'"'; __file__='"'"'/tmp/pip-install-b8co1_ap/pycurl/setup.py'"'"';f=getattr(tokenize, '"'"'open'"'"', open)(__file__);code=f.read().replace('"'"'\r\n'"'"', '"'"'\n'"'"');f.close();exec(compile(code, __file__, '"'"'exec'"'"'))' egg_info --egg-base /tmp/pip-install-b8co1_ap/pycurl/pip-egg-infocwd: /tmp/pip-install-b8co1_ap/pycurl/Complete output (22 lines):Traceback (most recent call last):File "/tmp/pip-install-b8co1_ap/pycurl/setup.py", line 229, in configure_unixp = subprocess.Popen((self.curl_config(), '--version'),File "/usr/lib/python3.8/subprocess.py", line 858, in __init__self._execute_child(args, executable, preexec_fn, close_fds,File "/usr/lib/python3.8/subprocess.py", line 1704, in _execute_childraise child_exception_type(errno_num, err_msg, err_filename)FileNotFoundError: [Errno 2] No such file or directory: 'curl-config'During handling of the above exception, another exception occurred:Traceback (most recent call last):File "<string>", line 1, in <module>File "/tmp/pip-install-b8co1_ap/pycurl/setup.py", line 970, in <module>ext = get_extension(sys.argv, split_extension_source=split_extension_source)File "/tmp/pip-install-b8co1_ap/pycurl/setup.py", line 634, in get_extensionext_config = ExtensionConfiguration(argv)File "/tmp/pip-install-b8co1_ap/pycurl/setup.py", line 93, in __init__self.configure()File "/tmp/pip-install-b8co1_ap/pycurl/setup.py", line 234, in configure_unixraise ConfigurationError(msg)__main__.ConfigurationError: Could not run curl-config: [Errno 2] No such file or directory: 'curl-config'----------------------------------------

解决安装失败的步骤如下:

sudo apt-get install libcurl4-openssl-dev
sudo apt-get install python-dev
sudo apt-get install libssl-dev
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()
