curl代理

命令行
=======

http/https代理
-------------------

- 命令行 ``curl`` 可以直接使用代理::

   curl https://reqbin.com/echo -x myproxy.com:8080 -U login:password

举例，我在 :ref:`nodejs_dev_env` 需要安装 ``nvm`` ，但是 raw.githubusercontent.com 被墙，所以需要通过以下命令通过代理访问::

   curl -x 192.168.10.9:3128 -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash

socks5代理
------------

- 命令行 ``curl`` 可以使用 ``socks5h`` 方式::

   curl -x socks5h://localhost:1080 -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash

持久化配置
==========

http/https代理
---------------------

- 环境变量设置::

   export http_proxy=http://192.168.10.9:3128
   export https_proxy=$http_proxy

- 或者采用 ``~/.curlrc`` ::

   proxy=192.168.10.9:3128

socks5代理
------------

比较特别，对于socks代理，变量是使用全部大写字母:

.. literalinclude:: curl_proxy/socks5_proxy_env
